Is anyone else seeing the possible security risk shown in the 'Vision and Face Recognition' section? The main concern I would have is someone spoofing the visual recognition system with something as crude as photographs, or something more advanced like a mask. He states in that section, "Once it identifies the person, it checks a list to confirm I'm expecting that person, and if I am then it will let them in and tell…

Rather what the hell happened to the guy that had tape on his laptop camera and microphone. Suddenly he's got an always on listening device. How does one go from one to the other?

I think it's just to demonstrate a fun and cool hack. Security wasn't at the forefront here when designing it.

> Add face recognition, so it can recognise people at his door and automatically open it if they are expected I wonder if you could open his door with an A4 printout of his face. That's the sort of thing I'd worry about creating this system. Edit: Forgive me HN, it looks like a lot of people have wondered this. I only commented so high up because I commented before reading all the comments! Go upvote the more creativ…

There's a decent way to handle this method: use one of the Intel close RGBD cameras. I think they go by RealSense. Now, do facial recognition with the depth component. "Oh look, paper. How quaint... NOPE!" You could also log all people coming by with a known-unknown axis. You could train the system so that all they need do is look at the door, and they have the appropriate access they need. And it could also, instead…

So I make a 3d printed head of zuckerberg from a composite of online photos. Easy.

Somewhere in between he was also the guy who used the password "dadada" for at least two of his online profiles.

More than anything else, what stood out to me was his discipline for knowing how to manage his time in a way that enabled him to build something like this while still juggling the n number of other things on his plate.

I dunno--like any CEO or even VP or SVP-level executive, I'm sure he can afford executive assistants at work and nannies/assistants/drivers/servants at home to take care of all the normal mundane aspects of life that suck up so much of normal people's time, getting in the way of side projects.

I'd guess he has more free time than the random "3rd engineer from the left" on one of his company's projects.

Indeed. Security isn't a binary. There's plenty of layers. And we went from

"Print picture" to

"Compute Sfm 3d object from thousands of photos, and have access to a 3d printer that large that can print human-sized heads, and paint it appropriately in the correct color-space as to trigger the right facial recognition"

It's then trivial to add a feature of 'Blink' and 'Smile'. We have public, free haar and lbp cascades for those. It would be a few lines to add in a check that requests those 2 actions.

"Then you have to print an articulated skull and musculature that activate the appropriate smile/blink responses, with the correct coloring across the face."

And then hope that the video feed of the disjoined head trying to pass as human isn't just sent to the butler or a family member for "quality control"....

Sounds like he knows where the data being recorded is always going and what's being done with it. Pretty different from the chance that a camera/mic on a laptop might be randomly sending data to some third party.

I've wanted to test something similar - holding up a giant "Speed Limit: 75MPH" sign when a google car drives by on these little 30mph Mountain View roads and see what happens. Probably nothing but I can't shake the comical thought of one of those little bugs rocketing to turbo mode while the dude inside is frantically slapping the big red "stop" button.

It hopefully uses it's GPS in combination with the Google mapping data for speed limits along with signage on the road. Hilarious to think about nonetheless.

Probably right, because when I use google maps' navigation mode, it sometimes has a little speed limit sign in the top right corner.

Here's what I absolutely love about this... He's still a hacker. CEO of one of the biggest internet companies of our time and he still hacks. I explain to people all the time, true hackers are like true writers. I've heard writers talk about the same thing. It's like an urge of creativity inside you, you have to release it into something. You can also see in the comments section, he's replying to people and providing…

Funny thing: Based on the screenshot in the post header, he's using async/await and therefore the Hack language (instead of vanilla PHP): https://docs.hhvm.com/hack/async/introduction
