Essay: What is Biometrics
Biometrics, an automated method of recognizing a person based on physical or behavioral attributes, has long been used by the government’s super-secret agencies for access-control applications and by law enforcement for large-scale fingerprint applications.
Now, as the cost of the technology has decreased and biometrics increasingly is integrated into keyboards and mice, federal agencies are expanding the technology’s use into applications such as battling entitlement fraud. The FBI has begun using the technology to replace handwritten signatures to secure the “chain of custody” for criminal records. “It does provide a positive verification that the person is who she is supposed to be,” said Ken Scheflen, director of DOD’s Defense Manpower Data Center.
