WEBVTT 00:00:06.710 --> 00:00:08.389 Hey it's Norm from tested and I am here with: 00:00:08.389 --> 00:00:09.709 Frank Bullito 00:00:10.178 --> 00:00:12.089 We're here at Adam's shop for another video 00:00:12.105 --> 00:00:14.922 Interesting video this time, it's an experiment. 00:00:15.469 --> 00:00:17.521 yeah An honest to goodness experiment. 00:00:17.781 --> 00:00:20.105 We have no idea how this is going to end. 00:00:20.366 --> 00:00:22.962 So today we're going to talk about technology. Are you comfortable? 00:00:23.232 --> 00:00:25.210 ok.. Special effects and technology 00:00:25.384 --> 00:00:27.904 Last year apple released the iPhone 5-S, 00:00:27.904 --> 00:00:30.494 which was their first product using 'Touch I.D.' 00:00:30.528 --> 00:00:33.417 You've probably heard of Touch I.D., it's a bio-metric sensor system 00:00:33.594 --> 00:00:36.473 for your phone, to double as your password. 00:00:36.639 --> 00:00:38.970 Now this year there are more products using Touch I.D. 00:00:39.122 --> 00:00:40.382 and more services using them, 00:00:40.588 --> 00:00:43.984 it's being used for things like Apple-pay, passwords, one password 00:00:44.162 --> 00:00:48.285 And we wanted to see, basically how fool-proof it was. 00:00:48.442 --> 00:00:52.968 We're not going to hack Touch I.D people have made claims about hacking it 00:00:53.134 --> 00:00:56.638 Last year a hacking group over in Germany 00:00:56.799 --> 00:00:59.194 named 'Chaos Computer Club' released a video 00:00:59.361 --> 00:01:01.454 showing how they 'spoofed' Touch I.D 00:01:01.612 --> 00:01:04.005 and what they did was they duplicated someone's fingerprint 00:01:04.166 --> 00:01:07.880 and put it on acetate and created a relief image, 00:01:08.045 --> 00:01:11.089 and it was a pretty involved process. 00:01:11.338 --> 00:01:14.455 But we wanted to- We wanted to make it more involved 00:01:14.693 --> 00:01:18.059 Even more involved, but basically try to understand how Touch I.D works. 00:01:18.254 --> 00:01:19.835 Um, do you know how this works? 00:01:19.970 --> 00:01:21.118 Why don't you explain. (laughs) 00:01:21.247 --> 00:01:25.628 So beneath this home button on the iPhone and the new iPads 00:01:25.834 --> 00:01:29.102 is a sensor, basically an optical sensor, almost like a camera. 00:01:29.309 --> 00:01:32.767 There is a capacitance sensor, which makes the touch screen work, 00:01:32.926 --> 00:01:35.066 so it knows, it registers that your finger is there. 00:01:35.257 --> 00:01:40.709 But basically it takes a high resolution image, people have said it's about 500 dpi. 00:01:40.876 --> 00:01:46.142 Which is fairly high, Apple talks about sub-dermal imaging, but basically, 00:01:46.467 --> 00:01:50.783 it knows all the grooves and all the curves of your fingerprint 00:01:50.783 --> 00:01:54.240 and registers that, uh because you do need to register it multiple times, 00:01:54.240 --> 00:02:00.920 stores it locally, so when you put your finger on there it recognises that it is your fingerprint. 00:02:01.118 --> 00:02:06.265 So we wanted to see if we could activate, unlock a phone, activate Touch I.D 00:02:06.461 --> 00:02:09.837 without having the actual hand there; a warm bodied hand, 00:02:10.043 --> 00:02:12.325 maybe a.. dismembered hand. There you go. (laughs) 00:02:12.500 --> 00:02:17.486 So this is actually a hand-cast we did a couple of months ago, of my hand 00:02:17.733 --> 00:02:21.468 It's just a silicone hand-cast and based on your experience in the 00:02:21.666 --> 00:02:25.675 special effects industry Frank, how accurate is the fingerprints 00:02:25.675 --> 00:02:27.889 on something like a hand-cast? 00:02:27.889 --> 00:02:30.854 Well, I mean, the silicone doesn't shrink or expand or anything, 00:02:30.854 --> 00:02:33.720 so it's pretty accurate, as long as we got in all the detail 00:02:33.859 --> 00:02:36.610 This was done in an alginate mold, so the detail might be a little soft 00:02:36.794 --> 00:02:39.889 but what we'll do today is we'll do a little silicone cast of your finger 00:02:40.054 --> 00:02:43.210 ..or my finger and we'll see if we can crack it with that. 00:02:43.438 --> 00:02:46.192 So we're talking about mold materials and casting materials 00:02:46.383 --> 00:02:50.479 and we're using silicone as a mold material and in doing it right- 00:02:50.588 --> 00:02:52.368 You're going to get a more accurate casting. 00:02:52.534 --> 00:02:56.794 Hopefully it will be almost exactly 1-to-1, y'know.. microns of accuracy. 00:02:56.964 --> 00:02:58.081 Hopefully. Hopefully. 00:02:58.256 --> 00:03:01.977 And then the casting material, also important. yeah 00:03:02.133 --> 00:03:04.900 'cause you have resins and silicones and all sorts of stuff. 00:03:05.080 --> 00:03:08.134 Well the pad of your fingertip is about a 35-A durometer, but- 00:03:08.299 --> 00:03:11.881 When you say Durometer that's how stiff it is, how rigid it is 00:03:11.881 --> 00:03:14.196 Yeah, the Durometer scale is how you measure how soft 00:03:14.196 --> 00:03:16.921 or how rigid something is. There's an 'A' scale for soft things, 00:03:16.921 --> 00:03:19.194 and a 'D' scale for rigid things. 00:03:19.194 --> 00:03:22.509 And your thumb-tip is about a 35-A. ok 00:03:23.036 --> 00:03:25.890 But, the problem is is that when we push on a button 00:03:26.086 --> 00:03:29.476 it doesn't have enough give to kinda like.. flatten out, 00:03:29.660 --> 00:03:32.095 so I think we want to go a little bit softer. 00:03:32.254 --> 00:03:35.617 So we were doing this off-camera, this casting is done in 00:03:35.811 --> 00:03:40.729 a 20 durometer silicone, which technically is softer than the 35 of your finger. 00:03:40.905 --> 00:03:43.443 I think we want to go softer than that, I have a 10 Durometer. 00:03:43.652 --> 00:03:47.339 That's right, you want it to be able to flatten without pushing the button. 00:03:47.484 --> 00:03:49.401 Yeah. 00:03:49.586 --> 00:03:51.555 Now the other piece of the puzzle is capacitance. 00:03:51.846 --> 00:03:54.462 You need to be able to activate that touch sensor in the first place. 00:03:54.614 --> 00:03:58.895 How are we going to give silicone capacitance? Because if you put a silicone finger, 00:03:58.908 --> 00:04:01.410 or you know, a hot-dog on here, it's not going to activate the touch-screen. 00:04:02.558 --> 00:04:04.712 Maybe a hot-dog will... would a- A hot-dog would, yes. 00:04:04.880 --> 00:04:07.265 But a silicone hot-dog wouldn't. We can make hot-dog fingers. 00:04:07.341 --> 00:04:08.425 uh.. we could do that. 00:04:08.524 --> 00:04:13.205 I think, from what everybody's told me, adding graphite is enough to 00:04:13.205 --> 00:04:17.050 give it capacitance. So that's mixing it into the silicone or powdering 00:04:17.050 --> 00:04:19.888 the surface of the mold, and then putting the silicone behind it 00:04:19.888 --> 00:04:23.731 so that the silicone grabs the surface of the graphite. 00:04:23.731 --> 00:04:25.052 We'll try it. We'll try it. 00:04:25.052 --> 00:04:29.178 Like I said, this is an honest-to-goodness experiment and- 00:04:29.178 --> 00:04:31.312 And there's a good likelihood we'll fail. (laughs) 00:04:31.312 --> 00:04:35.231 But follow along the process, let's go to step one 00:04:35.231 --> 00:04:37.802 which is creating a casting of your finger. 00:04:37.802 --> 00:04:42.755 If you're using 'body double' from 'Smooth-on,' which is just a casting silicone, 00:04:42.755 --> 00:04:47.153 Specifically for life casting. For life casting, it's accurate as possible, 00:04:47.153 --> 00:04:50.615 we've done life-casts with it before, you mix in a little bit of material as well? 00:04:50.615 --> 00:04:56.384 I mix in a thickener called '5X,' instead of using Cabosil or something fumey 00:04:56.387 --> 00:05:00.039 to thicken it, it's just a couple drops of this liquid and it gets thick. 00:05:00.039 --> 00:05:04.266 And then you're, in terms of making the mold, you're just doing a thin coating 00:05:04.266 --> 00:05:08.107 of silicone, just to get into those grooves and make sure it's a strong relief, 00:05:08.107 --> 00:05:11.847 a perfect copy, and then just slather that silicone on top. 00:05:11.847 --> 00:05:14.310 Yeah. I kinda smeared it into the grooves of my fingertip. 00:05:14.310 --> 00:05:16.120 And then built it up so that it has some thickness. 00:05:16.120 --> 00:05:18.650 Alright, so now it's time to wait until this cures. 00:05:20.410 --> 00:05:24.002 Ok Frank, while the silicone mold on your finger is curing, 00:05:24.002 --> 00:05:26.777 Let's begin experiment 2. 00:05:26.777 --> 00:05:29.752 Another way we thought we could 'spoof' Touch I.D. is 00:05:29.752 --> 00:05:33.221 if someone left their fingerprint on a piece of glass for example, 00:05:33.221 --> 00:05:39.805 and we'd captured it photographically. So we had you put you finger right here 00:05:39.805 --> 00:05:44.173 on some baby powder and put it right on this piece of foam-core. 00:05:44.173 --> 00:05:49.277 This is basically the equivalent of putting your greasy finger on glass, for example. 00:05:49.277 --> 00:05:54.771 Which is what the 'C.C.C.' did. So, we took a photo of this, 00:05:54.771 --> 00:05:57.826 took a macro photo, blew it up, very high resolution 00:05:57.835 --> 00:06:01.543 with my camera and then processed it on a computer 00:06:01.548 --> 00:06:04.641 to scale it, to be exactly the size of your finger. 00:06:04.647 --> 00:06:08.742 Measured it, it was about an inch tall. And then I laser etched it. 00:06:08.742 --> 00:06:13.859 So I tried several variations, laser etched of different relief. 00:06:13.859 --> 00:06:15.934 With laser etching y'know- Different depths. 00:06:15.934 --> 00:06:19.387 Yeah. Different depths, changed the colour, inverted it, uhh but basically 00:06:19.387 --> 00:06:25.666 used this as a substitute for your finger and then mold on top of that, 00:06:25.666 --> 00:06:29.669 or cast on top of that. We're not sure if that's going to work either, 00:06:29.669 --> 00:06:31.882 but we also want to create the molds here. 00:06:31.882 --> 00:06:33.789 And also using silicone. Sure. 00:06:34.297 --> 00:06:37.125 I ran some 'Body Double' onto these etched parts, 00:06:37.267 --> 00:06:40.696 to see how they come out and some of them look like they're actually going to work. 00:06:40.871 --> 00:06:43.464 So what we want to do is we want to dust them with graphite. 00:06:43.627 --> 00:06:46.419 And then, put some more silicone on top of this, and then 00:06:46.648 --> 00:06:48.135 we can use it as kind-of a finger pad, 00:06:48.363 --> 00:06:53.106 You know, because it's thin and flexible and maybe that.. that will work. 00:06:53.298 --> 00:06:57.744 So we're going to do some mental gymnastics here, 00:06:57.907 --> 00:07:02.876 the photo of your fingerprint, which I blew up and high-contrasted, 00:07:03.081 --> 00:07:06.323 made sure that all the curves were very visible. 00:07:06.563 --> 00:07:10.058 That was the reverse of what your fingerprint actually is. 00:07:10.188 --> 00:07:15.328 So without inverting it, without flipping it back, just etching that, 00:07:15.503 --> 00:07:19.209 basically, what you're going to get on the etch is what you would get 00:07:19.375 --> 00:07:22.788 on the foam-core here or a fingerprint on the phone. 00:07:22.983 --> 00:07:27.507 And so when we create the silicone casting on top of that, 00:07:27.613 --> 00:07:30.129 this isn't the mold, this is the fingerprint. Yes. 00:07:30.313 --> 00:07:34.914 Ok. So put some graphite on there and we'll mix up some more 'Body Double' 00:07:35.076 --> 00:07:38.525 And we'll add a little graphite into the 'Body Double' 00:07:38.686 --> 00:07:41.551 Just to help with capacitance maybe, I dunno. 00:07:50.645 --> 00:07:52.845 It's black like tar! 00:07:55.415 --> 00:07:58.350 So the cast of your finger is about done. Yeah, this is all solid now so.. 00:07:58.917 --> 00:08:02.028 What you do is just kind of peel it off. 00:08:02.028 --> 00:08:04.433 Because it's in all the detail of my finger it's got a lot of suction. 00:08:04.629 --> 00:08:06.340 That's good. Yeah. 00:08:06.797 --> 00:08:12.383 Take a look at that, you can flip it inside-out and see all those ridges and grooves, 00:08:12.575 --> 00:08:15.441 There you go Internet, copy this and go hack all my passwords. 00:08:15.586 --> 00:08:17.669 That's a good looking fingerprint. 00:08:17.853 --> 00:08:21.761 So what we'll do is put a few different materials into this. 00:08:21.933 --> 00:08:27.369 But, we have another copy of the fingerprint etched at a different DPI 00:08:27.506 --> 00:08:30.024 and we'll smear some more stuff into that. Yeah. 00:08:30.220 --> 00:08:35.419 My question and my concern with the laser etching is the resolution you can etch. 00:08:35.617 --> 00:08:42.321 And you can change that on the laser cutter, so I have 500ppi, 600ppi and 800ppi. 00:08:42.497 --> 00:08:45.797 ppi or dpi? It's.. sort of the same, points per inch. 00:08:45.990 --> 00:08:46.652 ok. 00:08:47.022 --> 00:08:54.026 And the higher we go the more chance that the acrylic will get fused into the crevices 00:08:54.220 --> 00:08:59.280 and the dust will take away some of the detail, but that- you can recognise it as a fingerprint 00:08:59.423 --> 00:09:02.748 I just don't know if it will be good enough to fool Touch I.D. 00:09:02.887 --> 00:09:05.556 You don't know if we're good enough to fool Touch I.D? 00:09:05.716 --> 00:09:08.010 Are we smarter than Apple? Probably not. 00:09:19.775 --> 00:09:24.101 Alright, back to experiment 1, the hand-cast - the finger cast 00:09:24.277 --> 00:09:26.543 and you're going to put some silicone in there. Yeah. 00:09:26.652 --> 00:09:29.291 So first thing I'm going to do is hit it with a little bit of release 00:09:29.431 --> 00:09:31.909 This is just 'Ease-release 200.' 00:09:32.088 --> 00:09:34.035 We actually haven't seen you use mold remover before, 00:09:34.222 --> 00:09:36.274 this extends the life of your molds. 00:09:36.502 --> 00:09:39.440 Yeah, if you want to cast like Urethane parts or something like that 00:09:39.615 --> 00:09:43.321 this works great, it just happens to be what I have sitting around right now. 00:09:43.530 --> 00:09:47.977 I want to put release on here because nothing sticks to silicone but other silicone, 00:09:48.153 --> 00:09:50.464 but we're putting silicone in here so.. Oh.. 00:09:50.661 --> 00:09:53.908 So I'm spraying it in and just sort of rubbing it around 00:09:56.875 --> 00:10:04.273 So what I'm going to do on this first is I'll rub some graphite into the surface 00:10:04.437 --> 00:10:06.186 kind of like how I dusted the etching. 00:10:06.414 --> 00:10:09.450 You've gotta be careful, this is really tricky because we want just enough graphite 00:10:09.655 --> 00:10:15.821 to activate Touch I.D, and the activation I think happens around the ring of the home button 00:10:16.030 --> 00:10:20.695 But we don't want too much graphite, because that might take away the detail. 00:10:20.889 --> 00:10:25.481 I want to Imagine Apple engineers watching this and just laughing their butts off. 00:10:25.638 --> 00:10:30.260 'Those fools, those morons, they'll never do it.' 00:10:32.905 --> 00:10:35.854 So this is the rubber I'm going to use, the 10 Durometer, 00:10:36.077 --> 00:10:38.250 for this stuff we were using the 'Body Double' because it was real thin and 00:10:38.477 --> 00:10:40.736 it'll just serve as a pad you put on your finger. 00:10:40.937 --> 00:10:45.702 So this one- I'll make kind of a full finger, sort of like this stuff. 00:10:45.982 --> 00:10:50.573 And I'll do another one that's just kind of a pad we can put on another finger. 00:11:05.131 --> 00:11:08.452 Alright, so the castings are done. The silicone has cured, 00:11:08.492 --> 00:11:10.719 It's time to pop 'em out of the molds. Yep. 00:11:11.030 --> 00:11:13.792 So what we have here, we actually did more than 1. 00:11:14.051 --> 00:11:20.015 A silicone casting from a silicone mold, pops out and how do the fingerprints look? 00:11:20.207 --> 00:11:25.941 I think that the detail is really great, it's about as exact of a replica of a fingerprint 00:11:26.158 --> 00:11:29.458 as you can get from your fingerprint, but we'll see if it reads on the Touch I.D. 00:11:29.619 --> 00:11:32.780 And then also the silicone we used on top of the laser etching, 00:11:32.933 --> 00:11:37.645 we pulled those out as well. And the advantage of these is that 00:11:37.814 --> 00:11:42.010 if someone wanted to 'spoof' someone elses fingerprint, this is more likely 00:11:42.157 --> 00:11:45.338 how they would be able to do it. They're not going to be able to get someone to 00:11:45.501 --> 00:11:47.984 put their finger in a mold for 15-20 minutes. 00:11:48.200 --> 00:11:50.012 They're more likely to take a photo of their fingerprint, 00:11:50.193 --> 00:11:52.000 from a touchpad or piece of glass or something, 00:11:52.190 --> 00:11:54.637 and see if they can laser etch it. Yeah. 00:11:54.867 --> 00:11:58.081 Plus these are thinner. Yeah, that'll help with the capacitance. 00:11:58.256 --> 00:12:03.020 It's like if you're wearing a rubber glove you can still activate your phone. 00:12:03.261 --> 00:12:06.797 So let's do a first test which is a test of capacitance. 00:12:06.938 --> 00:12:12.077 Let's unlock this phone, I'll just type in the passcode.. 00:12:12.089 --> 00:12:20.421 And show that using the graphite infused silicone works, just to manipulate the touch screen. 00:12:20.581 --> 00:12:22.875 Alright, that seems to be working. 00:12:24.312 --> 00:12:32.199 Let's try with this now, this is Franks finger. Oh, no capacitance. 00:12:32.784 --> 00:12:37.995 Umm.. we could try wetting it or..- Putting some graphite on top of it. 00:12:37.995 --> 00:12:39.716 Yeah we could try those two things. 00:12:42.325 --> 00:12:45.376 This is tough because water just beads off silicone. 00:12:47.980 --> 00:12:51.574 Ok, a wet finger, a wet finger-casting. 00:12:52.117 --> 00:12:54.407 That activates the screen. Mm-hmm. 00:12:54.407 --> 00:12:58.347 But we don't know how that will affect Touch I.D. 00:12:58.347 --> 00:13:02.161 So this one's dusted with extra graphite. We'll see if that works. 00:13:02.815 --> 00:13:04.583 It does! Great. 00:13:04.745 --> 00:13:08.952 So capacitance is working, so here comes the moment of truth. 00:13:09.068 --> 00:13:11.231 Or failure. Or failure. 00:13:11.243 --> 00:13:12.183 (laughs) 00:13:12.408 --> 00:13:15.073 The moment of failure, potential failure. We'll call it that. 00:13:15.586 --> 00:13:19.313 I'll hit the top button on the screen, it's going to want to unlock. 00:13:19.671 --> 00:13:24.473 And we'll show that, for example, my finger doesn't unlock this. 00:13:25.733 --> 00:13:30.699 Your finger does unlock. My finger that was molded does unlock. 00:13:33.602 --> 00:13:39.286 And now let's put that on top of there. (gasp) 00:13:39.323 --> 00:13:40.935 It unlocked! It unlocked! 00:13:42.302 --> 00:13:45.702 Holy moly! We fuckin' did it! 00:13:45.702 --> 00:13:48.291 I'm genuinely shocked, I didn't think it was going to work. 00:13:48.834 --> 00:13:51.089 Let's see if we can duplicate that. Alright.. 00:13:54.291 --> 00:13:59.031 Let's do- let's prove that this finger here does not work. 00:14:01.387 --> 00:14:04.958 Try again Does not work, ok. 00:14:05.196 --> 00:14:08.058 (gasp!) We did it. 00:14:08.921 --> 00:14:12.178 (laughs) Huge success. 00:14:12.927 --> 00:14:15.238 Test 1, experiment 1; Success. 00:14:15.807 --> 00:14:17.585 I'm going to try it on my finger. 00:14:22.552 --> 00:14:24.555 So let's talk about what did work. Ok. 00:14:25.047 --> 00:14:30.636 Experiment 1: we did a silicone casting of your finger, with a silicone mold 00:14:30.951 --> 00:14:33.586 that you carefully made, also of the same index finger. 00:14:33.860 --> 00:14:37.771 Now with the silicone casting we infused it with graphite, which by itself 00:14:37.952 --> 00:14:43.326 didn't seem to activate the capacitance ring on the Touch I.D sensor. 00:14:43.620 --> 00:14:49.187 But by brushing graphite on top of it, that actually made it register as a finger. 00:14:49.449 --> 00:14:55.346 And, with one of our castings we were able to unlock the phone. 00:14:55.942 --> 00:15:01.384 And the cooler thing even, is that on new iPhones 6 and 6+, is theoretically 00:15:01.565 --> 00:15:05.896 more improved, the sensor on the inside is higher resolution. 00:15:06.132 --> 00:15:11.548 And even on the 6+, where we trained beforehand, your index finger but not mine... 00:15:12.735 --> 00:15:14.293 It unlocks! 00:15:14.905 --> 00:15:17.321 So now I can unlock Will's phone any time I want. 00:15:18.146 --> 00:15:20.963 Well.. if your fingerprint was stored in it, yes. (laughs) 00:15:21.366 --> 00:15:24.454 But the other thing we have to test of course is the laser etching process. 00:15:24.696 --> 00:15:30.985 This is taking a high resolution photograph left on a surface, laser etching it 00:15:31.222 --> 00:15:33.409 and then creating a mold of that. 00:15:33.882 --> 00:15:36.323 So we've cut out a bunch of our laser etched fingers, 00:15:36.962 --> 00:15:40.565 Let's go back to the 5-S, ok, and let's see if that works. 00:15:43.280 --> 00:15:47.789 So here I have your fingerprint theoretically, on top of mine.. 00:15:50.703 --> 00:15:53.728 ..'try again.' 00:15:55.689 --> 00:15:57.968 Come on!..... do something!.. 00:16:00.158 --> 00:16:07.059 So unfortunately, the laser etched and then cast silicone fingerprint doesn't work. 00:16:07.545 --> 00:16:13.667 What's interesting is that it does recognise on the Touch I.D, it is trying a fingerprint. 00:16:14.003 --> 00:16:17.468 Which, if you put any other capacitive surface on there- Like a hot-dog. 00:16:17.825 --> 00:16:21.181 Right. It knows that that's not a finger, so it wouldn't even try. 00:16:21.509 --> 00:16:25.220 So we got it to try, we got it to fail, but we couldn't get it to 00:16:25.400 --> 00:16:28.016 recognise it as your finger. Well.. 00:16:28.351 --> 00:16:31.213 At least we got one of them. At least we got one of them. 00:16:31.553 --> 00:16:35.904 This is really cool, we get to learn basically how Touch I.D. works in practice. 00:16:36.154 --> 00:16:39.780 We recognise it doesn't need a warm finger. Mmhmm. 00:16:39.994 --> 00:16:44.620 All you need is something that has the fidelity, the resolution of your fingertip 00:16:44.769 --> 00:16:48.868 and has enough capacitance to activate the ring. Yeah. 00:16:49.036 --> 00:16:53.360 So if your finger was chopped off, theoretically, it would still work. 00:16:53.553 --> 00:16:54.916 There you go. There you go. 00:16:55.789 --> 00:16:58.882 Touch I.D. tested, it's a fun project with Frank Bellino 00:16:59.942 --> 00:17:01.644 What else do you do? You do a bunch of other tests here or- 00:17:02.000 --> 00:17:05.309 Well, during the week, when I was at lunch and stuff like that, I tried a bunch 00:17:05.479 --> 00:17:08.661 of different things. One thing I did was take a ball of clay and just push 00:17:08.869 --> 00:17:12.470 my finger into it, to get a fingerprint in the clay, and put silicone into there. 00:17:12.556 --> 00:17:17.115 That didn't work either, these are attempts at just doing a fingerprint in clay. 00:17:17.289 --> 00:17:22.290 That's not enough resolution, the silicone mold gets a better resolution. 00:17:22.335 --> 00:17:24.202 So that's kind of the way to do that. 00:17:24.202 --> 00:17:27.782 Try different ways and you know what? If you have experience with special effects 00:17:27.868 --> 00:17:34.181 or casting.. or new ideas.. the Choas Compter Club, they posted their instructions 00:17:34.374 --> 00:17:39.873 we'd love to see your videos or your attempts at 'spoofing' Touch I.D. 00:17:40.069 --> 00:17:41.803 But this was a lot of fun! Yeah it was cool 00:17:41.966 --> 00:17:46.837 I've never- I've always thought about this but never really tried it, but now we kind of know 00:17:47.033 --> 00:17:48.510 sort of what works. It's a fun experiment. 00:17:48.672 --> 00:17:52.448 Touch I.D tested here on Tested.
