Fingerprint-based user-friendly interface and pocket-PID for mobile authentication

This paper presents an enhanced user interface, "fingerprint user interface (FpUI)", that exploits fingerprint identification technology, and discusses its application to information systems, specifically to a mobile authentication terminal for networked services and digital appliances. FpUI utilizes information regarding not only who put a finger on its sensor but which specific finger it was. A user can assign commands, data objects, status, or personalized settings to individual fingers for user-friendly direct manipulation. A mobile terminal, "pocket-PID", with fast, accurate fingerprint identification capability is proposed which features: an easy-to-use FpUI, high security, and secure and usable non-contact communication capability which facilitates implementation of networked services based on biometric user identification.
