Replacing Humans With CGI Animations To Protect Anonymity In Video Footage (thestack.com)

Posted by samzenpus on from the privacy-please dept.

An anonymous reader writes: New research (PDF) from the University of Zagreb proposes the de-identification of innocent individuals in closed circuit footage by replacing them with CGI animations which either guess their skeletal motion or impose the animation via Kinect-style movement sensors. In order to preserve the raw footage, the original frames are then re-encoded via steganographic techniques into the final amended output.

    How is this different than simply blurring out other than being more complicated?

    Nice idea from academia but it seems like it's something that current operators of CCTV wouldn't use unless they were legally forced to.

    I'm confused. If you want to keep the original, why not just keep it somewhere else rather than jumping through hoops and potentially bringing its authenticity into question?

    "...the de-identification of innocent individuals"

    So whoever is left is guilty, right? That'd be a convenient way for juries to decide things...

      That is one of the ways they use a game engine to gamify/monetize stuff like airport security in Neal Stephenson's REAMDE. Except I think they used orcs.

      That group of bovine standing over there appears quite portentous. That's right it's an ominous cow herd.
