FINGERPRINT RECOGNIZING INTEGRATED CIRCUIT

摘要

PROBLEM TO BE SOLVED: To provide a fingerprint recognizing integrated circuit with which a fingerprint recognizing system can be constituted on an LSI chip and an extremely small fingerprint recognizing system can be constituted.

SOLUTION: The fingerprint recognizing circuit is obtained by mounting on a single integrated circuit a sensor means to detect the fingerprint of a finger as electric signals by laying a plurality of sensor circuits to convert unevenness of the fingerprint to the electric signals and bringing the finger into contact with the same, a fingerprint memory means constituted of memory circuits to which fingerprint data are preliminarily registered, and a fingerprint recognizing means to collate the electric signals transmitted from the sensor means with the fingerprint data in the fingerprint memory means.
