In light of a pilot project on the use of devices for biometrical face recognition at a Berlin train station, the Berlin Data Protection Officer, Maja Smoltczyk, has pointed out the severe risks of such techniques in a press release. Unlike conventional video surveillance that only observes passengers, biometrical face recognition can also identify and profile them. Given this technique could be used without the knowledge of the persons concerned, Smoltczyk stated that devices used for biometrical face recognition severely interfered with personality rights and may be used only under very strict conditions.
