| Abstract: | This paper describes a ubiquitous user authentication system consisting of a wireless fingerprint identification module and service‐providing equipment that offers services to the user. Users carry their own module and the user can activate the module only by identifying the fingerprint. The wireless communication between the activated module and the equipment enables continuous user authentication. This authentication certifies not only the presence but also the absence of the genuine user. The identification module was built with a fingerprint identification LSI (FIL) that senses and identifies fingerprints on a single‐chip. The LSI makes a small, light, battery‐powered tamper‐proof module possible. Two applications of the system were devised with the module. The experimental results demonstrate that the system authenticates the users continuously. The proposed system achieves ubiquitous user authentication which enables the authentication of the user anytime, anywhere. Copyright © 2007 Institute of Electrical Engineers of Japan.
