<p><P>PROBLEM TO BE SOLVED: To provide a personal identification system for quickening an authentication speed, and for decreasing an others acceptance rate. <P>SOLUTION: An electronic key 2αtransmits finger information added to an ID code signal for showing which of five fingers has been designated as a finger to be authenticated. A collation device selects biological information data (pattern data C) related with the finger (middle finger) designated by the finger information included in the ID code signal as reference data. Then, the collation device collates detection data by a finger vein sensor as a sole reference data, and when the both data are matched, the collation device decides that a testee is a legal user. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
