Design of a Wireless Fingerprint Authentication Service Platform Using the SOPC Technology
Fingerprint authentication is becoming an important security requirement in various embedded systems. While traditional identification method, user ID plus password cannot satisfy users' needs due to various defects, they are increasingly being replaced by biometric technologies such as fingerprint, face, and voice recognition, which are known to provide higher levels of security for user authentication. In this paper, an effective wireless fingerprint authentication system is presented. The authors designed the wireless fingerprint authentication based on Altera's Nios II processor. The whole system design includes real-time fingerprint image collection, image preprocessing, feature extraction, matching processes, a database and wireless transmission.
