Large-Area Biometric Specimen Comparison With Small-Area Biometric Sample
First Claim
Patent Images
1. A method of comparing a biometric sample to a biometric specimen, comprising:
- using a large-area biometric reader to enroll a biometric specimen, the specimen being a representation of a first area of an object;
using a small-area biometric reader to obtain a biometric sample, the sample being a representation of a second area of an object, the first area being larger than the second area;
comparing the sample and the specimen;
determining whether the sample matches a portion of the specimen; and
providing a signal indicating whether a match was determined between the sample and the portion of the specimen.

Abstract
Methods and systems according to the invention may compare a large-area biometric specimen and a small-area biometric sample. For example, a large-area plain surface fingerprint image may be stored in a fingerprint database as a specimen, and then a small-area plain surface fingerprint image may be acquired as a sample. The small-area image sample may be submitted to a fingerprint matching system for comparison with a large-area image specimen from the database. A determination may be made as to whether the small-area image matches a portion of the large-area image.

8. A biometric matching system, comprising:
-
a large-area biometric reader (“
LABR”
) capable of being used to enroll a biometric specimen, the specimen being a representation of a first area of an object;
a small-area biometric reader (“
SABR”
) capable of being used to provide a biometric sample, the sample being a representation of a second area of an object, the first area being larger than the second area; and
a computer, in communication with the LABR and the SABR, and having software running thereon which is capable of (a) making a comparison between the specimen and the sample, (b) determining whether the sample matches a portion of the specimen, and (c) providing a signal indicating whether a match was determined between the sample and the portion of the specimen. - View Dependent Claims (9, 10, 11, 12, 13)
