Apparatus and method of fingerprint recognition for a mobile terminal
First Claim
1. An apparatus for recognizing a fingerprint of a mobile terminal comprising:
- a fingerprint sensing unit for scanning a fingerprint of a user;
a storage unit for storing a comparison model of the fingerprints of the user; and
a controller for comparing a similarity between the scanned fingerprint and the comparison model with a certain threshold value, and releasing a lock function set in a mobile terminal or releasing the lock function and updating the comparison model according to the comparison result.

Abstract
An apparatus for recognizing a fingerprint includes a fingerprint sensing unit for scanning a fingerprint of a user; a storage using for storing a comparison model of the fingerprint of the user and various threshold values; a control unit for obtaining similarity between the fingerprint of the user scanned by fingerprint sensing unit and the comparison model stored in the storage unit, comparing it with a certain threshold value, and controlling a mobile terminal according to the comparison result; and a display unit for transferring a result (success or failure) of the fingerprint recognition or a request from the control unit to the user.

15. A mobile terminal apparatus comprising:
-
a fingerprint sensor to recognize a fingerprint inputted from a user;
a memory to store a reference fingerprint of the user; and
a processor cooperating with the fingerprint sensor and the memory to perform the steps of, determining whether the inputted fingerprint matches the stored reference fingerprint, authorizing the user if the determining results in a match, and updating the memory to replace the stored reference fingerprint with the inputted fingerprint, if the inputted fingerprint has a quality that exceeds a threshold value. - View Dependent Claims (16, 17)
