So I did talks at both that Black Hat and Def Con this year. 375 00:22:05,730 --> 00:22:10,410 And so that the Def Con talk will be posted publicly when Def Con posts us. 376 00:22:10,410 --> 00:22:13,850 And I

really highly encourage anybody interested in this topic 377 00:22:13,850 --> 00:22:16,330 to watch it because I show how I show the math, right? 378 00:22:16,370 --> 00:22:18,610 Go into how this works and all of those kind of things. 379 00:22:18,850 --> 00:22:21,250 But the Kickstarter has been insane, right? 380 00:22:21,250 --> 00:22:24,650 So what that proves to me is that people care about their privacy, right? 381 00:22:24,650 --> 00:22:27,890 So what I'm releasing is basically three garments. 382 00:22:27,890 --> 00:22:31,610 I'm releasing a T-shirt, a hoodie, and I don't know if you've ever watched 383 00:22:31,610 --> 00:22:35,410 a show, Survivor, but yeah, Buff, like a tube of fabric. 384 00:22:35,410 --> 00:22:38,330 You can either wear the headband or over your face. 385 00:22:38,850 --> 00:22:41,050 And each one of them target different things. 386 00:22:41,050 --> 00:22:45,810 So the T-shirt and the hoodie target the object model, the person object model. 387 00:22:45,810 --> 00:22:51,370 So if you are wearing this T-shirt or hoodie, you are not identified as a person, right? 388 00:22:51,370 --> 00:22:54,810 And what I mean by that is that little bounding box is not drawn. 389 00:22:54,810 --> 00:22:56,370 They don't know what you are. 390 00:22:56,370 --> 00:23:00,570 Yes.
