Are we sleepwalking into a surveillance society?

Personal Identity technology (ID-tech) is the complex of devices and techniques by which the identity of individuals is established and/or verified. It largely consists of biometric systems, that is, automated technical systems that measure physical human characteristics, some of them dynamically and in real time. The biometric device matches the input sample against a stored template, in order to include or exclude an individual from some action or activity. It is used for verifying who you are (with smart card, username or ID number) or identifying who you are. The data so collected could be used for purposes other than those initially intended.

Fingerprint biometrics were first used at the 2004 Olympic Summer Games, Athens. In the USA, Australia, UK, EU and other countries biometrics are being introduced into passport and visa control. For example, citizens of Brazil have their signature, photo, and 10 rolled fingerprints collected by passport requests. There is a very wide variety of uses e.g. in immigration, customs, ATMs, retail, schools, policing, and intelligence.
