Abstract

The present invention provides an electronic key device which can combine a fingerprint with an input ID code to generate a key signal to initiate a computer system. The key device comprises a fingerprint input module for inputting a user's fingerprint to generate a fingerprint image signal, and a fingerprint encoder having a memory for storing the fingerprint image signal, an input ID code and a fingerprint encoding program, and a processor for executing the fingerprint encoding program. The fingerprint encoding program is used for converting the fingerprint image signal according its characteristics into a digital fingerprint code, and encoding the fingerprint code and the input ID code according to a key encoding procedure to generate the key signal.
