When Mark Zuckerberg appeared before the House Energy and Commerce Committee last week in the aftermath of the Cambridge Analytica revelations, he tried to describe the difference between “surveillance and what we do.” “The difference is extremely clear,” a nervous-looking Zuckerberg said. “On Facebook, you have control over your information… the information we collect you can choose to have us not collect.” But not a single member of the committee pushed the billionaire CEO about surveillance companies who exploit the data on Facebook for profit. Forbes has uncovered one case that might shock them: over the last five years a secretive surveillance company founded by a former Israeli intelligence officer has been quietly building a massive facial recognition database consisting of faces acquired from the giant social network, YouTube and countless other websites. Privacy activists are suitably alarmed.
