Dialogue: 0,0:00:09.35,0:00:11.25,Default,,0000,0000,0000,,So I thought I'd talk about identity.
Dialogue: 0,0:00:11.25,0:00:13.77,Default,,0000,0000,0000,,That's sort of\Nan interesting enough topic to me.
Dialogue: 0,0:00:13.77,0:00:16.95,Default,,0000,0000,0000,,And the reason was,\Nbecause when I was asked to do this,
Dialogue: 0,0:00:16.95,0:00:20.51,Default,,0000,0000,0000,,I'd just read, in one of the papers,\NI can't remember,
Dialogue: 0,0:00:20.51,0:00:23.65,Default,,0000,0000,0000,,something from someone\Nat Facebook saying, well,
Dialogue: 0,0:00:23.65,0:00:25.89,Default,,0000,0000,0000,,"we need to make everybody\Nuse their real names"
Dialogue: 0,0:00:25.89,0:00:28.24,Default,,0000,0000,0000,,and then that's basically\Nall the problems solved.
Dialogue: 0,0:00:28.24,0:00:29.86,Default,,0000,0000,0000,,And that's so wrong,
Dialogue: 0,0:00:29.86,0:00:33.80,Default,,0000,0000,0000,,that's such a fundamentally,\Nreactionary view of identity,
Dialogue: 0,0:00:33.80,0:00:35.90,Default,,0000,0000,0000,,and it's going to get us\Ninto all sorts of trouble.
Dialogue: 0,0:00:35.90,0:00:37.40,Default,,0000,0000,0000,,And so what I thought I'd do
Dialogue: 0,0:00:37.40,0:00:41.57,Default,,0000,0000,0000,,is I'll explain four\Nsort of problems about it,
Dialogue: 0,0:00:41.57,0:00:43.53,Default,,0000,0000,0000,,and then I'll suggest a solution,
Dialogue: 0,0:00:43.53,0:00:45.54,Default,,0000,0000,0000,,which hopefully\Nyou might find interesting.
Dialogue: 0,0:00:45.54,0:00:47.65,Default,,0000,0000,0000,,So just to frame the problem,
Dialogue: 0,0:00:47.65,0:00:49.24,Default,,0000,0000,0000,,what does authenticity mean?
Dialogue: 0,0:00:49.24,0:00:53.100,Default,,0000,0000,0000,,That's me,\Nthat's a camera phone picture of me

Dialogue: 0,0:00:55.31,0:00:56.34,Default,,0000,0000,0000,,[What's the Problem?]
Dialogue: 0,0:00:56.34,0:00:58.07,Default,,0000,0000,0000,,That's a painting that was painted
Dialogue: 0,0:00:58.07,0:00:59.25,Default,,0000,0000,0000,,by a very famous forger,
Dialogue: 0,0:00:59.25,0:01:01.51,Default,,0000,0000,0000,,and because I'm not very good\Nat presentations,
Dialogue: 0,0:01:01.51,0:01:04.26,Default,,0000,0000,0000,,I already can't remember the name\Nthat I wrote on my card.
Dialogue: 0,0:01:04.26,0:01:08.13,Default,,0000,0000,0000,,And he was incarcerated in,\NI think, Wakefield Prison
Dialogue: 0,0:01:08.13,0:01:11.70,Default,,0000,0000,0000,,for forging masterpieces by,\NI think, French Impressionists.
Dialogue: 0,0:01:11.70,0:01:14.72,Default,,0000,0000,0000,,And he's so good at it,\Nthat when he was in prison,

Dialogue: 0,0:01:16.90,0:01:19.34,Default,,0000,0000,0000,,wanted him to paint masterpieces\Nto put on the walls,
Dialogue: 0,0:01:19.34,0:01:20.76,Default,,0000,0000,0000,,because they were so good.
Dialogue: 0,0:01:20.76,0:01:22.25,Default,,0000,0000,0000,,And so that's a masterpiece,
Dialogue: 0,0:01:22.25,0:01:23.93,Default,,0000,0000,0000,,which is a fake of a masterpiece,
Dialogue: 0,0:01:23.93,0:01:30.44,Default,,0000,0000,0000,,and bonded into the canvas is a chip\Nwhich identifies that as a real fake,
Dialogue: 0,0:01:30.44,0:01:31.97,Default,,0000,0000,0000,,if you see what I mean.
Dialogue: 0,0:01:31.97,0:01:33.16,Default,,0000,0000,0000,,(Laughter)
Dialogue: 0,0:01:33.16,0:01:35.41,Default,,0000,0000,0000,,So when we're talking about authenticity,
Dialogue: 0,0:01:35.41,0:01:40.87,Default,,0000,0000,0000,,it's a little more fractal than it appears\Nand that's a good example to show it.
Dialogue: 0,0:01:40.87,0:01:44.73,Default,,0000,0000,0000,,I tried to pick four problems\Nthat will frame the issue properly.
Dialogue: 0,0:01:44.73,0:01:46.29,Default,,0000,0000,0000,,So the first problem, I thought,
Dialogue: 0,0:01:46.29,0:01:48.64,Default,,0000,0000,0000,,chip and PIN, right?
Dialogue: 0,0:01:49.60,0:01:52.95,Default,,0000,0000,0000,,I'm guessing everyone's got\Na chip and PIN card, right?
Dialogue: 0,0:01:52.95,0:01:54.72,Default,,0000,0000,0000,,So why is that a good example?
Dialogue: 0,0:01:54.72,0:01:58.19,Default,,0000,0000,0000,,That's the example of how\Nlegacy thinking about identity
Dialogue: 0,0:01:58.19,0:02:01.11,Default,,0000,0000,0000,,subverts the security\Nof a well-constructed system.
Dialogue: 0,0:02:01.11,0:02:03.90,Default,,0000,0000,0000,,That chip and PIN card\Nthat's in your pocket
Dialogue: 0,0:02:03.90,0:02:07.14,Default,,0000,0000,0000,,has a little chip on it\Nthat cost millions of pounds to develop,
Dialogue: 0,0:02:07.14,0:02:08.72,Default,,0000,0000,0000,,is extremely secure,
Dialogue: 0,0:02:08.72,0:02:10.88,Default,,0000,0000,0000,,you can put scanning\Nelectron microscopes on it,
Dialogue: 0,0:02:10.88,0:02:13.06,Default,,0000,0000,0000,,you can try and grind it down,\Nblah blah blah.
Dialogue: 0,0:02:13.06,0:02:16.65,Default,,0000,0000,0000,,Those chips have never been broken,\Nwhatever you read in the paper.
Dialogue: 0,0:02:16.65,0:02:19.88,Default,,0000,0000,0000,,And for a joke,\Nwe take that super-secure chip
Dialogue: 0,0:02:19.88,0:02:23.40,Default,,0000,0000,0000,,and we bond it to a trivially\Ncounterfeitable magnetic stripe
Dialogue: 0,0:02:23.40,0:02:27.02,Default,,0000,0000,0000,,and for very lazy criminals,\Nwe still emboss the card.
Dialogue: 0,0:02:27.02,0:02:30.52,Default,,0000,0000,0000,,So if you're a criminal in a hurry\Nand you need to copy someone's card,
Dialogue: 0,0:02:30.52,0:02:33.63,Default,,0000,0000,0000,,you can just stick a piece of paper on it\Nand rub a pencil over it
Dialogue: 0,0:02:33.63,0:02:35.21,Default,,0000,0000,0000,,just to sort of speed things up.
Dialogue: 0,0:02:35.21,0:02:37.70,Default,,0000,0000,0000,,And even more amusingly,\Nand on my debit card too,
Dialogue: 0,0:02:37.70,0:02:41.17,Default,,0000,0000,0000,,we print the name and the SALT code\Nand everything else on the front too.
Dialogue: 0,0:02:41.17,0:02:43.44,Default,,0000,0000,0000,,Why?
Dialogue: 0,0:02:43.44,0:02:47.54,Default,,0000,0000,0000,,There is no earthly reason why your name\Nis printed on a chip and PIN card.
Dialogue: 0,0:02:47.54,0:02:49.18,Default,,0000,0000,0000,,And if you think about it,
Dialogue: 0,0:02:49.18,0:02:52.30,Default,,0000,0000,0000,,it's even more insidious and perverse\Nthan it seems at first.
Dialogue: 0,0:02:52.30,0:02:54.11,Default,,0000,0000,0000,,Because the only people that benefit
Dialogue: 0,0:02:54.11,0:02:56.68,Default,,0000,0000,0000,,from having the name\Non the card are criminals.
Dialogue: 0,0:02:56.68,0:02:58.33,Default,,0000,0000,0000,,You know what your name is, right?
Dialogue: 0,0:02:58.33,0:02:59.23,Default,,0000,0000,0000,,(Laughter)
Dialogue: 0,0:02:59.23,0:03:01.48,Default,,0000,0000,0000,,And when you go into\Na shop and buy something,
Dialogue: 0,0:03:01.48,0:03:03.82,Default,,0000,0000,0000,,it's a PIN, he doesn't care\Nwhat the name is.
Dialogue: 0,0:03:03.82,0:03:07.04,Default,,0000,0000,0000,,The only place where you ever have\Nto write your name on the back
Dialogue: 0,0:03:07.04,0:03:08.37,Default,,0000,0000,0000,,is in America at the moment.
Dialogue: 0,0:03:08.37,0:03:09.87,Default,,0000,0000,0000,,And whenever I go to America,
Dialogue: 0,0:03:09.87,0:03:12.66,Default,,0000,0000,0000,,and I have to pay with a mag stripe\Non the back of the card,
Dialogue: 0,0:03:12.66,0:03:15.82,Default,,0000,0000,0000,,I always sign it Carlos Tethers anyway,\Njust as a security mechanism,
Dialogue: 0,0:03:15.82,0:03:17.84,Default,,0000,0000,0000,,because if a transaction\Never gets disputed,
Dialogue: 0,0:03:17.84,0:03:21.47,Default,,0000,0000,0000,,and it comes back and it says Dave Birch,\NI know it must have been a criminal,
Dialogue: 0,0:03:21.47,0:03:23.74,Default,,0000,0000,0000,,because I would never sign it Dave Birch.
Dialogue: 0,0:03:23.76,0:03:25.21,Default,,0000,0000,0000,,(Laughter)
Dialogue: 0,0:03:25.21,0:03:27.24,Default,,0000,0000,0000,,So if you drop your card in the street,
Dialogue: 0,0:03:27.24,0:03:29.50,Default,,0000,0000,0000,,it means a criminal\Ncan pick it up and read it.
Dialogue: 0,0:03:29.50,0:03:31.99,Default,,0000,0000,0000,,They know the name,\Nfrom it they can find the address,
Dialogue: 0,0:03:31.99,0:03:34.13,Default,,0000,0000,0000,,and then they can\Ngo off and buy stuff online.
Dialogue: 0,0:03:34.13,0:03:36.27,Default,,0000,0000,0000,,Why do we put the name on the card?
Dialogue: 0,0:03:36.27,0:03:39.99,Default,,0000,0000,0000,,Because we think identity\Nis something to do with names,
Dialogue: 0,0:03:39.99,0:03:43.69,Default,,0000,0000,0000,,and because we're rooted\Nin the idea of the identity card,
Dialogue: 0,0:03:43.69,0:03:44.80,Default,,0000,0000,0000,,which obsesses us.
Dialogue: 0,0:03:44.80,0:03:47.49,Default,,0000,0000,0000,,And I know it crashed and burned\Na couple of years ago,
Dialogue: 0,0:03:47.49,0:03:51.95,Default,,0000,0000,0000,,but if you're someone in politics\Nor the home office or whatever,
Dialogue: 0,0:03:51.95,0:03:53.17,Default,,0000,0000,0000,,and you think about identity,
Dialogue: 0,0:03:53.17,0:03:56.46,Default,,0000,0000,0000,,you can only think of identity in terms\Nof cards with names on them.
Dialogue: 0,0:03:56.46,0:03:59.72,Default,,0000,0000,0000,,And that's very subversive\Nin a modern world.
Dialogue: 0,0:03:59.72,0:04:01.98,Default,,0000,0000,0000,,So the second example I thought I'd use
Dialogue: 0,0:04:01.98,0:04:03.62,Default,,0000,0000,0000,,is chatrooms.
Dialogue: 0,0:04:03.62,0:04:04.84,Default,,0000,0000,0000,,[Chatrooms and Children]

Dialogue: 0,0:04:22.67,0:04:27.39,Default,,0000,0000,0000,,Because that was very interesting,\Nwatching that experience as an old person.
