Abstract
Abstract The identification system comprises input means for collecting a fingerprint from the front end of a finger and converting the fingerprint to image data; an image memory for storing the image data; and means for storing the features of a plurality of fingerprints. The respective feature includes a plurality of feature points and the relationship between one of the feature points and the adjacent feature points. Furthermore, there are provided selecting means for selecting one of the features of the plurality of fingerprints; and identifying means for verifying the features of the image data obtained by the input means according to the feature of the fingerprint selected by the selecting means. This identification system is accurate, high reliable, inexpensive and suitable for controlling of entry to and exit from security areas and of commercial transactions.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
103 words
An identification system comprising; input means for collecting a streaked pattern of a fingerprint from the surface of a finger and converting said streaked pattern to image data; an image memory for holding said image data; storing means for recording pattern features of a plurality of registered fingerprints, said pattern feature including a plurality of feature points and relationships between said feature points; selecting means for selecting one of said pattern features corresponding to one of said registered fingerprints; and identifying means for verifying the features of said image data referring to said one of said pattern features selected by said selecting means.
Claim 2
Dependent Claim
103 words
An identification system comprising; input means for collecting a streaked pattern of a fingerprint from the surface of a finger and converting said streaked pattern to image data; an image memory for holding said image data; storing means for recording pattern features of a plurality of registered fingerprints, said pattern feature including a plurality of feature points and relationships between said feature points; selecting means for selecting one of said pattern features corresponding to one of said registered fingerprints; and identifying means for verifying the features of said image data referring to said one of said pattern features selected by said selecting means.
