The internet is slowly (and painfully) discovering that security is a hard mistress. I mean fingerprints have been hacked, and passwords have not been delivering for a long time. Next step was having a camera look at your face to see if you are really you.
Of course, the early systems could be hacked with a high quality printed photo. So security added a “check if it’s alive” method. That in turn was hacked using tablets and videos. The next step was to check if the received images makes sense (so videos were out). But then hackers started using 3D printed masks.
But 3D masks are hard to create. Why not just grab a few of your social media photos, and use those to create a model that looks so real that it fools security systems.
And this is what the team at University of North Carolina did.
