Your Facebook photos and can be used to circumvent facial recognition systems

Biometric identification is making great strides in recent years as a new method that enhance security-complementing passwords. And the facial recognition is one of the latest trends used by some of the largest technology companies to unlock our phones and computers.

But a group of researchers from the University of North Carolina (UNC) in the United States, has developed an attack with which they could skip this type of security systems. All you have to do is take some of the many personal photos shared on social networks and create a sufficiently detailed to deceive 3D model of our face.

Their study presented him with a show a couple of weeks ago during the security conference of the association Usenix. They make use of virtual reality to display on a mobile a 3D model of our face with movement and depth that often seek them recognition systems, and the five in which it succeeded tested in four.

The key is that we share photos

The great feature of this attack developed by the UNC is not using photos taken by developers study, but turn to gleefully shared on the network. On the show, they took 20 volunteers, and sought their photos via search engines or social networks like Facebook, LinkedIn or Google+, until between 3 and 27 photos of each.

With them, the researchers used a program created to identify the landmarks of the face of each individual, which then used to render it in 3D. Getting the best photos were the ones used to insert into the model data on the texture of the face, which had to be as realistic as possible.

Once created the version of the face of the volunteers, tested whether they could outsmart her five methods of facial recognition as KeyLemon, Mobius, TrueKey, BioID or 1D. All of them available to users in some models of smartphones and top – level software like Google Play Store or iTunes.

For the test, they first configured programs with real faces of the volunteers, and w
