Fingerprint authenticating system for carrying out a fingerprint authentication by using a small fingerprint sensor
First Claim
1. A fingerprint authenticating system comprising:
- a fingerprint registering unit; and
a fingerprint collating unit, wherein said fingerprint registering unit takes a first fingerprint data indicating a first portion of a first fingerprint from a first fingerprint sensor, registers said first fingerprint data to a memory unit, and takes a second fingerprint data indicating a second portion of a second fingerprint from a second fingerprint sensor, said fingerprint collating unit collates said second fingerprint data with said first fingerprint data to confirm whether or not said first fingerprint is equal to said second fingerprint, and an area of said first portion is equal to or larger than an area of said second portion.

Abstract
A fingerprint authenticating system includes a fingerprint registering unit and a fingerprint collating unit. The fingerprint registering unit takes a first fingerprint data indicating a first portion of a first fingerprint from a first fingerprint sensor, registers said first fingerprint data to a memory unit, and takes a second fingerprint data indicating a second portion of a second fingerprint from a second fingerprint sensor. The fingerprint collating unit collates said second fingerprint data with said first fingerprint data to confirm whether or not said first fingerprint is equal to said second fingerprint. Here, an area of the first portion is equal to or larger than an area of the second portion.
