Method for Encrypting and Identifying Fingerprint Image in Fingerprint-Identifying System

摘要

A method for fingerprint image encryption and recognition in the fingerprint recognition system includes: inputting a characteristic fingerprint image through a fingerprint acquisition device of the said system by a user as per a selected angle of imaging; extracting characteristic data from said characteristic fingerprint image; and storing said characteristic data in a form of data module to complete the encryption of the fingerprint image. A method of the present invention may change the data information of existing individual fingerprint characteristics by changing the angle of imaging when a fingerprint is input into the system so that the fingerprint image can be encrypted. Thus, the adverse consequences of a stolen fingerprint image can be avoided despite of objective openness of individual fingerprints. Methods of the invention minimize the security risks and protect users' interests.
