Abstract

The invention discloses an encryption method of biological features, an encryption matching method and an encryption system, and an encryption matching system. The encryption method comprises the following steps: respectively computing similarity and / or difference of a to be identified biological feature with each feature base in N feature base spaces to obtain a corresponding data set, thereby realizing the encryption on the biological feature; respectively computing the similarity and / or the difference of two to be identified biological features with each feature base in the feature base space, comparing the computing result in the one-to-one correspondence, thereby realizing the matching of two to be identified biological features. The to be identified biological feature is converted into a group of abstract code data, the group of code data supports the one-way encrypted storage, the matching of the biological feature based on the code data or the cipher text is realized, the requirement of the clear text of the biological feature is avoided, and the security of the biological feature on the identification is guaranteed.

Description

technical field

[0001] The invention relates to the technical field of biological feature identification, in particular to an encryption method of biological features, an encryption matching method and an encryption system. Background technique

[0002] Usually, the process of identity verification and authentication on the network is as follows: when a user needs a certain service (such as a mailbox), he needs to enter his account number and password on the client, and a well-managed service provider usually encrypts the user's input information It is transmitted to the server through a communication link, and the account password previously established by the user is stored on the server side in an encrypted manner. The server compares the information entered by the user with the stored account password to confirm their consistency, thus completing the identity verification process. It is easy to see that if the factor of the user side is not considered, the leak of the p...
