Surveillance Society: I read an article in the prestigious North American magazine "Technology Review" titled Big Brother Logs On of Ivan Amato (September of 2001). The article does an interesting swing of the recent developments in the modern digital technologies of vigilance. While cameras invade our streets, and programs record our expressions facial while we buy, our privacy is inevitably lost?! Most of the systems developed involve diverse forms of identification and verification through the biometric.
Biometrics is the science and technology of measuring and analyzing biological data. In information technology, biometrics refers to technologies that measure and analyze human body characteristics, such as fingerprints, eye retinas and irises, voice patterns, facial patterns and hand measurements, for authentication purposes.
Authentication by biometric verification is becoming increasingly common in corporate and public security systems, consumer electronics and point of sale (POS) applications. In addition to security, the driving force behind biometric verification has been convenience.
Biometric devices, such as fingerscanners, consist of:
A reader or scanning device Software that converts the scanned information into digital form and compares match points A database that stores the biometric data for comparison
To prevent identity theft, biometric data is usually encrypted when it's gathered.

To prevent identity theft, biometric data is usually encrypted when it's gathered.
Here's how biometric verification works on the back end: To convert the biometric input, a software application is used to identify specific points of data as match points.
The match points in the database are processed using an algorithm that translates that information into a numeric value. The database value is compared with the biometric input the end user has entered into the scanner and authentication is either approved or denied.
Also, I found this usefull link:
- The Biometric Consortium is a U.S. Government-sponsored focal point for information about biometrics, particularly for security uses.
