From the INS to ATM's, both the public and private sectors are making extensive use of biometrics for human recognition. As this technology becomes more economically viable and technically perfected, and thus more commonplace, the field of biometrics will spark legal and policy concerns. Critics inevitably compare biometrics to Big Brother and the loss of individual privacy. The probiometric lobby generally stresses the greater security and improved service that the technology provides. Is biometrics privacy's friend or privacy's foe? This paper explores the various arguments for and against biometrics and contends that while biometrics may pose legitimate privacy concerns, these issues can be adequately addressed. In the final analysis, biometrics emerges as privacy's friend.
