Dialogue: 0,0:00:01.84,0:00:03.60,Default,,0000,0000,0000,,So I thought I'd talk about identity.
Dialogue: 0,0:00:03.63,0:00:06.15,Default,,0000,0000,0000,,That's sort of an interesting\Nenough topic to me.
Dialogue: 0,0:00:06.17,0:00:09.56,Default,,0000,0000,0000,,And the reason was,\Nbecause when I was asked to do this,
Dialogue: 0,0:00:09.58,0:00:13.01,Default,,0000,0000,0000,,I'd just read in one of the papers,\NI can't remember,

Dialogue: 0,0:00:18.54,0:00:20.98,Default,,0000,0000,0000,,and then that's basically\Nall the problems solved."
Dialogue: 0,0:00:21.00,0:00:22.46,Default,,0000,0000,0000,,And that's so wrong,
Dialogue: 0,0:00:22.48,0:00:26.21,Default,,0000,0000,0000,,that's such a fundamentally\Nreactionary view of identity,
Dialogue: 0,0:00:26.23,0:00:28.63,Default,,0000,0000,0000,,and it's going to get us\Ninto all sorts of trouble.
Dialogue: 0,0:00:28.65,0:00:30.20,Default,,0000,0000,0000,,And so what I thought I'd do is,
Dialogue: 0,0:00:30.22,0:00:34.18,Default,,0000,0000,0000,,I'll explain four sort of\Nproblems about it,
Dialogue: 0,0:00:34.20,0:00:35.100,Default,,0000,0000,0000,,and then I'll suggest a solution,

Dialogue: 0,0:01:13.12,0:01:16.30,Default,,0000,0000,0000,,And so that's a masterpiece,\Nwhich is a fake of a masterpiece,
Dialogue: 0,0:01:16.32,0:01:23.01,Default,,0000,0000,0000,,and bonded into the canvas is a chip\Nwhich identifies that as a real fake,

Dialogue: 0,0:01:25.29,0:01:27.58,Default,,0000,0000,0000,,So when we're talking about authenticity,
Dialogue: 0,0:01:27.60,0:01:29.90,Default,,0000,0000,0000,,it's a little more fractal\Nthan it appears,
Dialogue: 0,0:01:29.92,0:01:32.10,Default,,0000,0000,0000,,and that's a good example to show it.
Dialogue: 0,0:01:32.13,0:01:37.43,Default,,0000,0000,0000,,I tried to pick four problems\Nthat will frame the issue properly.
Dialogue: 0,0:01:37.46,0:01:39.95,Default,,0000,0000,0000,,So the first problem, I thought,\Nchip and PIN, right?

Dialogue: 0,0:01:46.56,0:01:48.00,Default,,0000,0000,0000,,So why is that a good example?
Dialogue: 0,0:01:48.03,0:01:50.80,Default,,0000,0000,0000,,That's the example\Nof how legacy thinking about identity
Dialogue: 0,0:01:50.83,0:01:53.68,Default,,0000,0000,0000,,subverts the security\Nof a well-constructed system.

Dialogue: 0,0:02:09.28,0:02:12.54,Default,,0000,0000,0000,,And for a joke,\Nwe take that supersecure chip,
Dialogue: 0,0:02:12.56,0:02:16.22,Default,,0000,0000,0000,,and we bond it to a trivially\Ncounterfeitable magnetic stripe.
Dialogue: 0,0:02:16.24,0:02:19.43,Default,,0000,0000,0000,,And for very lazy criminals,\Nwe still emboss the card.
Dialogue: 0,0:02:19.46,0:02:23.11,Default,,0000,0000,0000,,So if you're a criminal in a hurry\Nand you need to copy someone's card,

Dialogue: 0,0:02:33.66,0:02:35.21,Default,,0000,0000,0000,,Why?
Dialogue: 0,0:02:35.75,0:02:39.87,Default,,0000,0000,0000,,There is no earthly reason why your name\Nis printed on a chip-and-PIN card.

Dialogue: 0,0:02:41.81,0:02:44.81,Default,,0000,0000,0000,,it's even more insidious and perverse\Nthan it seems at first.
Dialogue: 0,0:02:44.84,0:02:48.35,Default,,0000,0000,0000,,Because the only people that benefit\Nfrom having the name on the card

Dialogue: 0,0:03:17.83,0:03:19.87,Default,,0000,0000,0000,,So if you drop your card in the street,

Dialogue: 0,0:03:27.20,0:03:28.88,Default,,0000,0000,0000,,Why do we put the name on the card?
Dialogue: 0,0:03:28.90,0:03:32.49,Default,,0000,0000,0000,,Because we think identity\Nis something to do with names,
Dialogue: 0,0:03:32.51,0:03:36.55,Default,,0000,0000,0000,,and because we're rooted\Nin the idea of the identity card,
Dialogue: 0,0:03:36.58,0:03:37.75,Default,,0000,0000,0000,,which obsesses us.
