Last week, New York Mayor Michael Bloomberg joined NYPD Commissioner Ray Kelly to unveil a major new police surveillance infrastructure, developed by Microsoft. The Domain Awareness System links existing police databases with live video feeds, including cameras using vehicle license plate recognition software. No mention was made of whether the system plans to use - or already uses - facial recognition software. But, at present, there is no law to prevent US government and law enforcement agencies from building facial recognition databases. And we know from industry newsletters that the US military, law enforcement, and the department of homeland security are betting heavily on facial recognition technology. As PC World notes, Facebook itself is a market leader in the technology - but military and security agencies are close behind. According to Homeland Security Newswire, billions of dollars are being invested in the development and manufacture of various biometric technologies capable of detecting and identifying anyone, anywhere in the world - via iris-scanning systems, already in use; foot-scanning technology (really); voice pattern ID software, and so on. What is very obvious is that this technology will not be applied merely to people under arrest, or to people under surveillance in accordance with the fourth amendment. No, the targets" here [include] everyone. In the name of "national security", the capacity is being built to identify, track and document any citizen constantly and continuously.
