Abstract

The invention discloses a biological characteristic encryption method. The method comprises the steps of obtaining biological characteristic information of a user; generating a biological characteristic plaintext according to the biological characteristic information; and generating a biological characteristic ciphertext through encryption of the biological characteristic plaintext in a hardware encryption mode. The invention also discloses a biological characteristic encryption device. The biological characteristic information of the user is encrypted through a hardware encryption circuit; the dependence of an algorithm on a processor is reduced; encryption is realized in a same chip; and the data transmission security and efficiency can be improved.

Description

technical field [0001] The invention belongs to the field of biological feature identification, and more specifically relates to a biological feature encryption method and device. Background technique [0002] With the development of electronic technology, biometric identification technology has been widely used in smart mobile devices. Taking smart phones as an example, biometric identification has become a mainstream configuration. Currently, biometric identification chips are used in smart devices as an independent module. The biometric identification chip collects the biometric information of the user in advance, and stores the biometric information in the mobile phone processing chip. In the verification stage, the user inputs the biometric information, and the input biometric information is compared with the preset fingerprint characteristic information; if the verification is successful, the unlocking can be completed. [0003] In the current biometric identificatio...
