Surveillance system scrambles people's faces

Example footage
A Swiss company has released a CCTV filtering system that masks the appearance of people in the video feed until an encryption key is used to unmask a specific individual:

Its developers say the system could let law enforcers use closed circuit television (CCTV) cameras without invading the privacy of those being watched. For example, a video stream could remain anonymous until its operators realise that a crime has been committed. The video could then be unscrambled by authorities with the necessary encryption key.

The potential application for this is huge. One of the key issues with servicing Subject Access Requests for CCTV footage is the thorny legal problem of whether to permit other faces to appear on the footage when it is released to the data subject; if this can be used to get around it then it removes one of the barriers to access to personal information held on video.
