Abstract

The present invention provides a method for protecting a biological characteristic formwork, a device and a system thereof, wherein the method comprises the following steps: ciphering the biological characteristic data of the user with the key for generating the ciphered biological characteristic data; and bonding the key with the biological characteristic data of the subscriber for generating the biological key corresponding with a ciphered biological characteristic data. The invention ciphers the biological characteristic data with the conventional key and bonds the conventional key with the biological characteristic data of the subscriber to generate the biological key corresponding with the ciphered biological characteristic data thereby obtaining the purpose of increasing the security and reliability for protecting the biological characteristic data. At the same time the security and reliability of biological identification are increased.

Description

technical field [0001] The invention relates to the field of image and recognition technology, in particular to a method, device and application for protecting biometric data. Background technique [0002] Biometric authentication is an effective identity authentication method. This method usually relies on comparing the biometric sample provided by the user with the biometric template generated during the registration stage. If they match, the user's identity is confirmed. [0003] But at present, apart from the reliability of biometric authentication technology itself, the key factor affecting its large-scale application is security. Among several security-related issues, the protection of biometric templates is an extremely important issue. It can be said that it is a biometric The foundation of authentication security. [0004] In the prior art, traditional encryption methods can be used to protect the biometric template. In this method, the security of the biometric te...
