Effective facial recognition detection software and systems have beeen in development in various parts of the world for several years. While the ability to recognise faces of real people moving through crowded urban environments in real-time is not yet a reliable prospect and/or an affordable reality in most cities (at least according to CCTV operators I've spoken to), the ability to scan static faces and two dimensional images has been getting more sophisticated for a while. Recently, for instance, the US Federal Bureau of Investigations announced that it would be adding facial recognition software and databases to its 'Next Generation Identification System', thus enhancing their biometric capabilities.
So, not surprisingly, facial recognition has become the target of activists concerned with issues of surveillance and privacy. Check out URME Surveillance, which offers a range of products designed to help people beat the recognition systems (and to raise awareness of the issues associated with new facial recognition technologies). Among the ideas here is the URME Surveillance Personal Suveillance Identity Prosthetic, which is a 3D printed mask letting you wear the artist's face instead of your own. There's a novel use of 3D printing ... go Leo!
