Inc. MasterCard is testing a fingerprint system and has considered voice recognition, face recognition, and eye-scanning security systems. There has been a stabilization among the players. The most significant thing is really the fact that the biometrics industry now has behind it more than 20 years of history and thousands of organizations that have successfully used the products. Because of the higher level of professionalism, research and development are bringing performance up and prices down. Physiological biometric identifiers include fingerprints, hand geometry, eye patterns, and facial features.
Behavioral identifiers are the voice and signature.
Voice print and signature analyzers are generally considered less conclusive because they are subject to such limitations as illness and imitation. Advances in computer technology and communication networks have made even huge fingerprint databases available for instant searches. The county database will eventually contain seven million records and be used by 10,000 users, including police, court, and pro-bation officers. Los Angeles County uses a similar system to isolate welfare fraud. Arizona uses an AFIS from Morpho Systems of Tacoma, Washington to enroll applicants for public assistance.
