#RFC 1984 - or Why You Should Start Worrying About Encryption Backdoors and Mass Data Collection
1:51PM Aug 2, 2020
You have to make sure the person feels that they're helpful. Don't nobody likes to feel like they're wrong So don't ever make somebody feel like they're they're wrong, and be open and honest. So,
greetings from Philadelphia.
This is Bernie s, and this is my botnet server of 50,000 honeybee bots. You're my backyard.
How you doing girls
like the paper.
Check out their friends.
Welcome back to fall 2020. Do you get worried. Authorities say give up a little bit of your privacy, to keep the bad guys away. And this talk is meant for you. From CCTV to Facebook, people have little understanding of why mass collection of data is dangerous. Our next talk, why you should start worrying about encryption back though, and mass data collection or In short, RFC, 1984 by Esther Fay. She's an IP professional with two decades of work experience. And currently, part of library cast live TV team project which is funded by nn net foundation. Esther is looking forward to the next stage of the Internet, and to help bring it back to its decentralized roots. So let's hear that from Esther on how do we slay the Hydra of mass surveillance.
Nice. To start, I'd like to consider the metaphor of putting a small creature, like a frog in a bowl of cool water, and then galatian heating up that water and think about that metaphor well I see a few students but privacy. Now, do we need privacy or family friends to anything online including pictures of their lovely children. And those children grew up, and teenagers have been using the internet since it's been a thing. And so they have no concept of personal sharing everything. So I said, Forget it, let's suppose we put in an interconnected world now we know everything about each other. And we need to give up some of that privacy enemy for biosecurity and against terrorism and to track people who are suffering with COVID-19. So I mean, you're that creature, how's that water feeling for you. So humanity's got a very difficult problem at the moment. We need to be able to explain the concept of privacy and what that means in this modern age. But this isn't the first time humanity's had to grapple with complicated concepts, we had to do that when civilization started off on the Greeks, with Aesop's Fables and Greek mythology, is a good example of explaining those concepts to us. So we'll start off. And I'll give you an example of those myths orbit of it wasn't Greek, he was Roman, And what it was was a ploy. During the last part of the reign of Augustus, and the beginning of the reign of Tiberius Augustus the successor Augustus, Howard effectively won the civil wars, and he began the transition to take power. Absolutely. So, Jared mess he maintained that no he wasn't going to be a dictator. Like dictators, don't like kings either. He wasn't he was not king he wasn't a dictator, what he was was the first citizen. Just because you happen to have other peripheral rules like see consular types, on the point is Maximus, which was the chief priest of jewel, who was the father of gods and is the Roman equivalent to Zeus, not not us just our citizen wasn't keen at all. On towards the end of his brain. He was also transitioning Roman society to be more and more for the focus of Romans to be on the family, and of his being young, being an edgy poet thought Virgil was stuffy and he was gonna like really shock people with what he wrote, and what he thought were a few words like I guess which were about Greek parents. fasti which was about the religious calendar of events Morphosis, which is a treaties on change on the doors. Most often, covering when Gold's going change mortals and names for supposedly frivolous reasons, they got a bit offended. I know when he finally bought his copy copybook entirely by car samata, which pickup artists love notice it apparently tells you who's going seduce a woman, and then get rid of Roman don't classic scholars, do not like that. Do more see to them bulky top set of tiny little bit of a rumored affair with Augustus his granddaughter Juliet. So Augustus decided to perform equivalent of kancil culture was there, or you know was I like to call it consequences of a danger of in exile in the Black Sea and he was lucky, because he could have got killed instead, and spent his time, ultimately finishing up the metamorphosis. But he kept on his salt is about salting authority and fasting when he kept trying to suck up to them to come back from Expo. And when Augustus died, he petitioned Tiberius, and Toby's was having none of it. So, what was the main tale that he that we're covering today, they're often covered. We're going to cover, are you in our guest. Are you an artist, arcus. Oh you was a beautiful, lovely gorgeous men and Zeus beings this Amman who, who had a string of
infractions decided that he wanted some about, so he decided to do one proposition I, I said no. And then just ignore that. And in order to cover up what he was doing because he is wrong, and he also was a bit scared of hair. He covered the entire land in Cologne to cover up what he was doing to write her notice because you know when your person in authority, or you're trying to cover up something that you know is wrong do nippy possibly be Korean people tend to notice because of the cover up. So Hara being up for the Olympics so this massive closed flop suit is up to people again, so she decided to wander on day. And so she saw this there. And what she saw standing there besides this was Carrie, and she went. Hey, there's
just a code that I got given us a gift. And yeah, that's just the code.
She said was Percy anyway yes yes dictate code, that's fine. I'm just going to go now.
And Zeus, gets away, scot free. In the meantime heritage sites that she's going fifth simply and punished for by you. So she puts you under constant surveillance on imprisonment, and the way she does this is with that Shepard called artists and artists on artists binoculars as a journey. But what he also has are hungry eyes, and they're dotted all around his body. And he doesn't really need sleep, to show, which will affect his surveillance, because only two his eyes need to close in order for him to sleep. So I O is imprisoned by the shepherd. He follows her everywhere she has a limited amount of space to go and run. And she has no privacy. So she's suffering there but eventually she wants to get away for a tiny bit. And she gets to work her father, who then puts a lot of pressure on Sue. Sue. Sue starts to feel, you know, tiny bit guilty, maybe the optics aren't very good when you go to record slagging off. And so he decides to do something meditech. And he went to harm he suddenly got problem. Get this code, a week from artist and Hermes is like yeah all sorted for you. Oh 100 bees, it was he said difficult to do a social export. On August, notice, so we wonder told August is really, really boring story. An artist fell asleep. And he's killed him. Or you managed to run away. And Hara not quite been done yet because she still wants to punish the victim decided to go and send the gadfly off the island. And no matter how far, or you fled the gun flight procedure and kit, lighting, and you know, there's definitely some modern day perils that when you see whistleblowers like Snowden, and eventually she wanted over in Europe or Asia stopped or further have now killed or from exhaustion and became human again. What did all of it, bring to the table well Tiffany, because the original greatness actually hard. Are you as he says love are so heavy as media,
though, but just swipe it No really.
And the other thing that he brought to the tail was Gox Hara was so suicide avert her
means of constant surveillance so another being being killed, she decided to immortalize him by placing his eyes or mark of a peacock. But what does this have to do with nowadays. So starting from the political ramifications and relevance of folding teaches us. We're still inspired quite a bit by August you notice that hungry, giant. We care more about technology. If you're a modern firm and you want to show that you're a really good surveillance option. You're calling yourself you know army's video and in the middle of that your slap the big iron right in the middle of your logo. And even the formalities. The Army's konocti cannot please inspire Jeremy Bentham Benson was kind of industrial revolution, philosopher, and he helped anything from this tech group. He wanted to improve a lot of things. And he created the pinup skin. And it's a very simple concept. You have a series of cells ranging for, say, a building filled with cells, and in the center of that building you have a tower. The tower is mainly closed off, but the light shines through terror, and it can shine a light on any one of the cells that are dotted around the structure, the people within each cell cannot see who's watching them, that means they're being surveilled. And this is a this is a very effective way of encouraging people to see, keep on with that work because Bentham's idea was originally for things like managing prisons, but it was also for managing hospitals and the time of quarantine.
And also for industrial processes for factories, so
he was trying to industrialize people make them atomic bombs and Michel Foucault in his Greek discipline and punishment explains this further in the section of his book called docile bodies where he explains where the panopticon could have been beneficial when he talks about a time during the 17th century, when there was plenty going on and had to quarantine. And all of the human rights violations that had to happen people have to be kept in sight.
everybody thinks about the idea of being surveilled or they don't think about why what purpose surveillance is for
George Orwell. He is in 1984. goes into this further. Everybody focuses on the Newspeak on the brainwashing But what they don't focus on is the simple act of everybody being constantly surveilled, and everybody feeling the need to report on everybody else. This is, he explores the idea of what it's like to live in economic society. It's not just people are being observed to tell the screen so they better behave themselves is actively brainwashing people to be docile, not question things not to question and government, not to protest. And part of that is ensuring that the citizens don't have privacy. And it was that very idea to privacy, that inspired the IETF in 1996, due to the long term in the article on cryptography. On the latest attempt by the US government to listening on encrypted communications by the clipper chip. We decided we had to create an RFC, as a statement of intent to see that we did not approve of what the government was trying to do, because we felt it was incredibly important for every user in the internet to have an adequate degree of privacy. The new that as time went on it. People want to buy and sell stuff on the internet, they want to exchange information and privacy is an incredibly important part of that. And in 2015, they decided to make it best common practice. Just because everybody was starting to think that privacy is quite an important thing, especially after the Snowden revelations.
Everybody shoots more about this RFC is quite an important.
The statement, or the RFC goes on about certain aspects, so they were worried about governments imposing restrictions on cryptography. And they were incredibly worried about governments making organizations produce software with weakened encryption that would be easy for those governments to break. Because if governments can break it you can guarantee that foreign governments can break it criminals can break it. And they also didn't agree with the idea of having a central registry of keys and a third party because that's a central repository of cryptographic keys.
And of course some visions out there don't like cryptography have told there is no privacy for people under those reliefs.
we shouldn't be worried about it we should know what is threatening our privacy. Governments for one thing. There is a constant need for them to push for putting a backdoor into all encrypted communications and the police don't need that backdoor. they already get lots and lots of information and intelligence, and they can't even sit through the existing stuff we've had terrorist incidents where the police have known about these terrorists, but they've been overwhelmed with the information and commercial organizations have a vested interest in collecting all of that data, partly for advertisers but also partly so we can sell that on to other interested individuals on our family on our friends want to use things like DNA testing companies because it's hard to find like a strain it's encouraged and you probably should know if there's anything wrong with you if there are any genetic things you should worry about in the future. All of these things are a threat to you. And if we look specifically at the political parts of it. Governments, haven't wanted people to use encryption at all. They've been conveniently ignoring the fact that we need them for our banking, there are certain things that shouldn't be unencrypted on, they also want to be able to wiretap our communications in the kind of digital crocodile clip that we used to be able to hold for months. William Barr the Attorney General in the US, keeps pushing for backdoors to be put into commercial software. And when you consider legislation to protect children to try and prevent child trafficking. They're trying to push in the agenda of knowledge math. Math, knowledge and mass data collection via things like airnet, and the online the harm suck which is meant to try and control what children see online and who they communicate with. And of course we're in the middle of a major pandemic where we're being encouraged to install applications on our form with varying degrees of security. Some are open source, some aren't. And we don't know what's going to be done with that data afterwards, there is no transparency on the process for how long that data needs to be kept for. And we should be worried about the aftermath of COVID-19 data collection. Because patient data can be D anonymized well de identified, and it can be sold on it has been sold on to pharmaceutical firms and private health firms to try and develop research which is a Moodle idea but what else can access like Doctor Who else can access some data. And we're being stored. Because if people aren't careful to secure that data, it can be found online. And even when you have a legal right to access large data, sometimes individuals who are in your organization can take a copy of it illegally and access it elsewhere or sell it onwards, political organizations have a vested interest in collecting all sorts of data including magazine subscriptions on how they're going to vote because we want to know who to the target there, who do the target who are swing voters who community, push to vote for one party or another. And all of that data can be collated together for firms like palantir to help organizations like immigration enforcement in the US to pick people up off the street, who are tangentially connected to that data to individuals. Under, we're normalizing this lecture No, we already live in a panoptix society with CCTV, we've grown up with cameras gradually taking over our city spaces and taking over airports, as well as we have it in our commercial spaces as businesses are encouraged to put CCTV in to protect themselves to be able to enforce the law to provide proof of prejudgment rather than looking at the causes of what causes crime.
And because we're all so worried about crime and about property theft rather than people. We ended up buying things like rain and contributing to social networks, where we put our own biases in those reports.
And it's a very privileged thing to do
with these networks. It's not us who are suffering with this is people at the margins of society who like the sharp edge who suffer from this, and we should be concerned when companies light comes in whoa very cozy relationship with law enforcement and sell these devices to sell the problem. And these networks are bad enough, but what happens when you add in official range and artificial intelligence to augment that facial recognition to do to consumers, it sold as a frictionless way to go about our lives we can no more performance we can get door entry, we can access government services. But what's that mean it means that governments have a copy of some of our biometrics we have more choice in this if we want to travel around the world, and schools are using it to track attendance. In some cases to track if students are paying attention in classes.
And we get
if we want to feed things back to see a 711 store a bike, about how nice and served facial recognition is use their to our DNA testing kits, of course it's natural to be curious about where you came from. But people don't realize the consequences of signing up to these services to get your report back. There was a Bloomberg article in 2018, where the journalist found that she couldn't get her data that we did afterwards we legally couldn't do it. And not don't tell what can and will be handed over to law enforcement to track criminals. And sometimes that data is so going to pharmaceutical firms in order to help them develop trucks, I mean what's wrong with that i mean it's it's helping science. And surely, there's nothing wrong with doing that is that, well, you should be worried about it because your DNA. In addition to see medical records that have been de identified could be put together. And then imagine if publicly available medical records. Under DNA are combined and see sold to a company like palantir, whose secondary businesses insurance know for now we're meant to have safeguards. But there's no guarantee that those safeguards will always be in place. And once the data is collected and stored somewhere. It's forever. And when you consider using things like biometrics and gait recognition to ensure that people can get into security areas, you're collecting this data, but you're putting it somewhere where it can be stored. And that data can be hacked into to be spiked these systems aren't safe, just because unique identifiers are put into that system about you. I mean, all of these different things, individually they're not that much of a danger. But putting together, what you get, you get a modern version of the pinup ticket, except instead of that physical prison with the cells in the central tower. What you have instead are everybody looking at your profile. Every cell is available, with a focus on you, who you're contacting what you could talk about yourself, the trips you take on your own social network can be used against you, but it can also be used against other people.
So let's go back to that peripheral in that water heating up your that frog. You're feeling a bit toasty.
So do we need privacy. I mean our families are all in it. And we've all had those arguments, we've asked them, and you may well be in a stage where you're getting up, but you can't give up because there's still a risk to your privacy
and saying that teenagers don't care.
That's not true. Teenagers are used to being under constant surveillance and they don't like it,
but they've been used to encrypting their own messages. They've not even been using encryption to do it, they've been using steganography. They've encoded messages to each other that their parents don't know about. They've worked out with Taylor their message to different audiences. And they're actively protesting, and trying to disrupt data collection. They know to give false information, they're using it as a form of protest, but we're actively protesting against facial recognition on campuses, the next generation, absolutely have this. Do we need to give up privacy for, you know, our security, do I really thought worried about terrorists. I mean, the years President Eisenhower, he was fairly clear that yeah you can have security but you know you've got a new deputy. And that's an important part of human rights, you deserve to live your life with privacy and with dignity and without your government spying on every action you do, because this is what we're looking at. If you don't hold our governments in check. If we allow them to just collect and Doctor willy nilly because it's not really about active intelligence. This is about building cases. Afterwards, if you somehow fall for what you've done. And it doesn't matter where you are in society. It doesn't pay much for their own site.
So, is there hope dough, we're back to good Mexican. Best Group myth is with
a very, very distantly relation distant relation to oil, which was heavily so we use the Greek name of this problem in the Roman Empire to lease. Because, heck Hercules originally wasn't born had a place he was renamed terror, in an attempt to go and appease her because yet again. Zeus had she's with actually getting consent. And what he did this time was disguised himself as the husband of her Clarice's mother, because the husband was away at Moore's doing battle. This way. I know what we'll do. I'll go and disguise myself as this king, get my anyway. And then, you know what, I'll be fine. Oh, yeah, Mark. Awesome. And so he he was determined to his mother, and he went, hey, I did so well in this bottle because I'm like your husband's. She's like, Oh, I see savvy Coleman, do things. And then of course we throw that day, I realized he comes home he goes hey babe, but when the boss is just like but but you are here already. Anyway, no it was just like. So, this man that Harry please had a fraternal twin brother because Greeks obviously didn't have modern medicine genetics. So, Hara being justifiably upset that this is don't again decides that she's going to yet again. Take it by on the victim, and also in the victim's children this time I mean, Goddess of currents are what she first of all attempted to stop Zeus from being bored by kidnapping the gods to childbirth. And then eventually this is born as Mrs brother, but the damage was done because Hercules had a cousin on, basically, we've got to the kingdom. The line was whoever was born first so because it got priced in Hercules got to be a hero and said, yay, participation. But,
Hercules grew up got strong and married and had children of inherit still been a tiny, tiny bit vindictive sense of mud, so hard that he murdered his wife and children. Once Hercules got our sovereignty back who is quite rightfully gravely upset about it, knowing that it can bring bad luck to him and once we went to go. What do we do better and heroin well you must have torn. And in order for you to at all, you're gonna have to go to your cousin that he's going to give you 10 tasks to do things and only once he's satisfied. will you be forgiven. No, Ted. Ted Talks on peace Hercules is famous for 12 tasks. But we'll get into that. I'm actually going to focus on one of the tasks in particular, which was sadly not alone does the task. So this task was a learning in Hydra. This was a nine headed monster that was terrorizing the type of learner. No terrorizing wasn't bad enough. It was also events, so it was poisoning the vocal waterlilies for the assembly just back to the tape. So this was a saved as a task by Heather who is his cousin. So how to please go along to the circle Yeah, just chop his head off. Chop the Hydros head off. one of
the head you back and he's like,
and try chopping off again. No, scroll back, and had a Gleason score oh it was with
a little grab a burning grant, we can cauterize it. So how to please try third time,
saw me so hard head goes off, I was cauterizes in the head. This goes on for nine heads. All the worst ones immortal, because it was a mythical creature. And so, what he did was, when I say what are you don't want to birdie it did be fine. How to police it that defeated the monster and this goes away. You hired help this task does not count. No, technology, like tonight any technology we have is a tool can be used for good can be used for evil on things like mass data collection on facial recognition are Hydras. We're never going to get rid of it. But what we can do is we can limit the use of these technologies, so back from mythology land, once again, the thing you have to realize is that it does not want to call it technology that cannot kill mass surveillance. This is the Hydra in our society is built on data, how we interact with that data. It's a mortal. We're never going to get rid of it. We can temporarily disable these technologies we can put laws in to try and check abuse of those technologies, mass data collection is a hydrated facial recognition is a Hydra head. we can look at a lot more surveillance technologies, and they're all Hydra heads. How do we do these cut off the head, how do we stop and going back in Legends. The last Hydra head is more to the right, it's not practical for you. You can't worry technology, you can lift it to use you can find it, you can discuss avoid these things aren't a good idea, which is why it's really good, that the mainstream press is starting to catch up with what's going on. We have the documentaries like the great heart we have the Snowden revelations we have a constantly updating sphere of information mainstream press, as they wake up to just how much power is being polluted with mass collection data on the legislature is waking up certain cities in the US are actively farming official records recognition. The EU was considering a five year moratorium and then walk it back but the conversation is still open. And that's the important thing. And, as I said earlier. The Kids Are All Right, they're going to keep protesting because it's not just about on individual spirits about what we want to be as a society. And you're all here watching this talk, and other talks. I hope you're learning how to do nice things you're looking at starting conversations. So, we can defeat the Hydra we can disable it, we can call it on to do that, you need to do your own research. You will have various human rights violations careless collections of data going on in your area and it's important to keep an eye on your local networks. And if you're a developer, look really hard at your doctor collection flows. Think about what you really need to collect doctor, make sure that communication is encrypted, build that in from the beginning, and get more information from privacy focused organizations online. Keep an eye on what darker legislation like GDPR and Privacy Shield, and other bits are doing. But, like anything before you can help anyone else you've also got to have a look at what your weaknesses are in terms of privacy, what services are you use. You've got kind of thrown that oxygen mask yourself before you help anyone else. And if you want your parents and your friends and your chosen family to stop using places like Facebook, you have got to build the new community for them to find Facebook started going in the first place, because of word of mouth, it wasn't just people going there's this new social network. It was. I've joined Facebook come and join me. It's organic, you can build these things. Join networks mastered under threat, if you haven't already
and use popular culture, use mythology use books, get people to start to empathize with each other and understand because you've got to get people to realize that they are that poor and financially that the beginning, poor or you got brutalized and turned into a cow, and then imprisoned, and constantly surveilled to nothing that she did, because that's happening to people out there right now they're being imprisoned about traveling are being surveilled, they're being brutalized and you have to get the rest of us to understand that, but you have to do it gently you can't run into people,
because we're all in the cab.
And we're all facing the panopticon we're facing that self, just because it's not physical doesn't mean it's not there. So, you have to find ways to open up the conversation with your friends and family just to have quite a coffee. Finding shows to watch together above water law. Use this time, Mo we're starting to come out with the pandemic. Just look what's happened watch along. Watch The Winter Soldier. And if you are posting about things and trying to get your friends and family interested in it. Consider how to start a conversation. Don't just say things like these networks are wrong if you bake knowledge for you so you can also use Facebook to communicate with your community and your friends. But what exactly are they doing with our data, make it a gentle argument because your friends and families they're scared stiff about what's going on out there, they know that they're, they're suffering. They know that Facebook's Facebook and other corporations have a lot of power over them, but they don't know what to do about it and run it and tell them that we're all just nice they're not going to come to you with their worries they're not going to come to you to see that they need help to protect themselves.
And every culture is different.
The English language is not the only one there, every culture has the wrong attitude to privacy so you have to think about what that means locally. And once you've become better at talking to your friends, your family, you and your friends and family can go and put proper pressure on your political representatives, you know don't underestimate the power of old people who don't have much to do other than write letters to the representatives, that's the kind of power you want, do you want everyone of every age to join you, to fight for privacy.
see. It's about control, it's about power. Knowledge is power, every doctor that goes into the hands of your government can be used against you. And it is important that we do not normalize this. Anytime that our CCTV cameras, just get the positive, you can do it as part of conversation. You can start to say this is normal, and it shouldn't be.
Because that semantic panopticon to me is a lot scarier than the idea of the physical penalty.
Just knowing how your social contacts, and what you and me, can do to use against you for them to try and predict your movements to predict how you can see been manipulated just go on election. And as I say, the last head of the Hydra is mortal we're never going to get rid of technology. And we shouldn't want to, but we should open a conversation to how it should be used ethically stayed vigilant, stay connected. And don't give up. This fight is never ending. But it doesn't mean you should stop and absolutely use the hashtag RFC mentality for use it when farms, aren't putting encryption into the products use it when they're using really lazy encryption, use it when you find out that governments have come to put pressure on those businesses to disable encryption, especially when we have companies like Clearview who are using that data inappropriately and so you wanted police forces.
Thank you, Esther for a wonderful presentation. Now it's time for question and answers from our audience.
A false question, your pick up background and screen layout, are great. What tools, did you use to produce your presentation.
Um, I had a little bit help with that. But we used FFmpeg, it's quite a, quite a good set of hashes for putting these things together, and I did produce the film on a digital camera. And I also quite like using latex as well to produce my slides because it means that I'm doing my content I can just focus on the content rather than how the layout is a big fan of simplicity.
There's another question. RFC 1984 published in 1996. What has changed. Do you think the authors from 1984 IFC had a clear and accurate vision, based on what we know today.
I don't say yes or no, because at the time when they were making Masonic See, you'd things like the clipper chip which was meant to be like the old pitting the crocodile clips on two phone lines on the original engineers who started the started the physical network itself in the 60s, they were concerned about privacy as it was so they had an idea about it, but I don't think the realized how much the collection of data and how much about how much we'd end up relying on that data in society. No, I don't think any of us in the earlier days of the internet back in the 90s thought it would be so ubiquitous.
And attendee wrote. So it's a question when I was reaching out to you. I am a teenager and I care. That is why I'm attending your talk, saying, teenagers, don't care is not fair, what is supposed to happen. When I haven't lived in a world without the Patriot Act and the PSA. It's kinda just hopeless. What's your response to this attendee.
Well, part of the reason why I said that question in the first place is because it tends to be brought up in our arguments, and it has been brought up since the days of MySpace and Bebo. People always like to say oh teenagers they're just on WhatsApp all the time they're just putting everything on porn lane without realizing that they view these networks, and they know they're not getting heavily supervised with that network but of course they care about privacy, because we were all teenagers once and we weren't used
to having our own privacy
and being able to have that privacy is important and certainly when you, when you have a car attacked the TSA when you're so used to your movements, being tracked and monitored. It's gonna be. Yeah, it's a different world from what
we have to let me start again,
you're not used to that world, and a lot of us have become that world we forgotten what it's like to be free that world. But privacy, part of the reason why it's an important human right is because you need privacy, you need to be able to formulate your thoughts and your arguments, so that you can form your own opinion that's one of the reasons why things like the metadata filter Arts in Australia, on the online harms on the internet are quite nasty, because the argument is used as we need to protect the children, and we need facial recognition to do that well there's more tools than just facial recognition to be able to track child predators, and things and teenagers still need to be able to search safely online. They need to be able to look up books like the case cookbook without it causing a whole raft of consequences. They need to have their privacy and they won't get it will be zapped, and the people who only benefit at the end of the day from these acts. And from that technology are actual criminals who can figure out how to evade it.
Still we just lost your audio.
Okay. You hear me.
Yes, it's better now. Okay, I have one last question,
please summarize your key requests or suggestions to our audience, and how they could help fight mass surveillance.
I would see start to reopen the conversation with the people that you care about that you know aren't as aware of what's going on out there, because there are lots of doctors here at home, and who have spoken at home in the past about the dangers and how to face those dangers. But one of the main things when I talk to friends in our space is that people don't want to listen, they're not open to the conversation yet. So we need to be open to that we need to be open to listening to our friends and family. See, and we need to be able to gently come to those arguments rather than going from a technical correct point of view of these are bad communities these Facebook is bad for you we need to try and rephrase it so it's perhaps we should consider looking elsewhere. And if you want to change the world, you need to help us change it, you need to join networks like mustard and white diaspora and get involved with activity pub, please.
All right, there's one more question. Hope has had similar talks about information literacy and fact checking how do those topics overlap with the privacy topic, you've just emphasized.
That's an interesting question. It can be interpreted in key ways.
But like, I think we have fact checking things out there, and we can definitely talk to each other and verify how accurate, our new uses, certainly, in terms of information resources whenever possible, we don't only rely on on official sources, but we look elsewhere we share them, and we make sure as much information as possible is up on the information archive, and we get involved with local groups as well because there are lots of local organizations who are concerned about surveillance.
All right, thank you so much Esther for talking to us and sharing your views, at home, 2020, we had a wonderful talk and interactive session with the audience. Thank you so much.
Thank you very much to you and to the whole audience for having me. Bye bye.
Money rock from Hawaii, I just wanted to say that great. Aloha to everyone out there well wishes of healthiness and happiness.
I'm a cybersecurity Project Manager for a government contractor
company here in
Hawaii. I'm also a pollination and
fire dancer, so I live a well balanced life in
technical and personable work, hope you're enjoying hope 2020 is a
little sample of my fire arts. Enjoy.
fabrication process that adds electrical functionality to various materials. You can create clothes which measure your body movement, provide heat in the cold, or even track your motion for VR, or lightened sound control. Our next talk is about fabric augmentation using tools you can find in any kitchen, we prevent. We present Cedric on a with Polly sense, reverse engineering flex sensors and destroying your kitchen with chemistry for electrical functionalisation of everyday objects.
Hi everyone, my name is Cedric, and we are going to present present an accessible process that makes fabrics smarter. Okay, so. This presentation will be chronological from the original problem to solutions that we found a few unexpected discoveries and opportunities for the future.
Let's start with the initial motivation.
So, this project was done, a hackerspace could achieve focus on index eyes, such as this matrix. Pressure Sensor. So these start to get a sense our uses two kinds of materials. Let's discuss first the conductive fabric. So on the right. We can see horizontal stripes used to sequence and power the Center for rasterization. We. On the left, we can see vertical stripes that are connected to the analog input of the afternoon. With a bit of base used to print versus the singer, and the as we know, reports the signal to the computer.
And in the middle. You can see a darker fabric.
This is the pixel resistant material. It changes its resistance when you press it. This material is expensive. It's about 200 grams per square meter. And it became harder to get over time. So, what this is a resistivity anyway. One of our goals on this project. And I'm gonna reason maybe some of you met her last year she was giving a couple of sessions and excite, and she is frequent visualization of what's happening inside. So we illustrated here as a layer of conductive particles are these brackets. But I think it's better to see it as fibers that were kept, and it's like a pepakura visualization of the fabric. So windows pressed together. The overall conductance increases, because each of them is fully conductive, but still conductive. So the fact that the conductance increases, it makes complete momentary behavior and the resistance. So, the resistance decreases when present. We can measure that with the Arduino. So we tried to make our own coating with silver, copper, carbon particles. And we really never got anything that were either would oxidize, It would not conduct at all.
Secondly, challenge was,
we realized that we didn't really understand the material.
And fortunately I made it train with a collaborator on that particular system from this book. And I spent a week in her material science lab. And after a few analyses, including Raman spectroscopy. We understood better, what could be in this reference better. So the Raman spectroscopy, to look looks a lot like a laser, but it's actually much smarter than that. What's happening inside is that there is. So you click a macro microscope. And it has a laser that shoots light in whatever you observing and it looks at what is coming back. The ladies first at a certain frequency. It's actually a scan swipe frequency and. And you can see what comes back, a bit like. It's try with it. If you think about it on the acoustic domain. When you look under
You can hear a specific acoustic signature. And when you look on something is unlike my phone. You can hear a different kind of sound. And this can be represented as a spectrogram. Well, this tool that I'm showing on the screen is doing the same but instead of sending an acoustic inverse, it sends a, an optical inverse. And we can see at the bottom right, some spectrograms that are representing the materials that we're observing. So, with the software you can point at the specific part of the method that you want to observe and it will tell you something like this looks like carbon graphite PSS or many other kinds of methods. And in our case, it's another one that I'm going to. So, thanks to the expertise of those friends, we have various ways to replicate this amazing thought that has this futuristic behavior. And we really worked out a secret process, but you didn't really get in your kitchen, so you don't have this method to that. You can see on the screen. We found this simple approach that only use two chemicals. One is called the hero. It's a mono layer, and I'll explain a bit later What are those things what what are their functions and what are their behavior, and the other is iron carbide. It's a fairly common chemical that is used in to make PCBs, so when you,
When you make a pre printed circuit boards.
Like the classic Arduino or whatever, you start from Plato's Cotter, and he was this thing. Most of the time. All
right, it has it anyway. It's fairly common in charity.
So, we use the magnetic stirrer, and you can see at the bottom. But you could use whatever you want the washing machine to to a blender I think you to me You're better.
Another Blender that has made us though because then.
So you can stick with whatever you want in your thing.
Pressure Sensor in about one hour with all of this data.
So you can see on the right. The first test that we did, so we dry the site, and we just measure the Z pressure. So the pressure between the bottom and the top. But we can measure the pressure, the resistance in different ways.
let's talk a bit about applications. Here's one of one of the applications that we did, we demonstrate one of them with Goggin.
