Abstract
A biometric authentication unit includes a position detecting section for detecting a user's finger position from a pressure distribution detected by a right-side pressure detecting plate, a left-side pressure detecting plate, a front-side pressure detecting plate, a rear-side pressure detecting plate and a fingertip pressure detecting plate; corrects a finger vein pattern of a registrant data on the basis of the difference between the detected user's finger position and a correct position; collates the acquired user's finger vein pattern with the corrected registrant data; and authenticates whether the user is the registrant.
Claims8
A biometric authentication unit comprising:
- an imaging section for taking through an opening an finger image of a person to be authenticated, the finger being placed opposed to the opening;
- a position detecting section for detecting a finger position of the person to be authenticated by a plurality of sensors arranged around the opening, the finger placed being opposed to the opening;
- and
- an authenticating unit for collating, by using the finger position of the person to be authenticated detected by the position detecting section, a finger vein pattern acquired from the finger image of the person to be authenticated taken by the imaging section with a previously registered finger vein pattern of a registrant, to authenticate whether the person to be authenticated is the registrant.
