<P>PROBLEM TO BE SOLVED: To remarkably reduce possibility caused by the determination of non-conformity between a user and feature data by combining both of a fingerprint feature data and the feature data of a blood vessel pattern though personal identification can be performed by using either one of the fingerprint feature data and the blood vessel pattern feature data. <P>SOLUTION: The personal identification device is provided with a fingerprint image reading unit, a means for extracting fingerprint feature data from a fingerprint image read by the fingerprint image reading unit, a reading part for reading a blood vessel pattern image, and a means for extracting the feature data of the blood vessel pattern from the blood vessel pattern image read by the reading part. An area for retreating the extracted feature data is formed and personal identification is performed by using the extracted fingerprint feature data, the blood vessel pattern feature data or the integrated data of the fingerprint feature data and the blood vessel pattern feature data. <P>COPYRIGHT: (C)2004,JPO |
