Embodiment Construction

[0026] Attached below figure 1 , attached figure 2 , attached image 3 The present invention will be further described.

[0027] as attached figure 1 As shown, a privacy-protected biometric authentication method in a cloud environment includes the following steps:

[0028] a) The authenticated user submits an authentication request to the identity authentication server, and the identity authentication server identifies the user's ID and password. After the identification is passed, the identity authentication server transmits the user ID to the database server through the network, and the database server indexes to the user registration time through the user ID The palmprint feature Feature, the database returns the palmprint feature Feature to the revocable feature server;

[0029] b) The revocable feature server obtains the palmprint feature Feature and extracts the competitive code feature of the special vector in the palmprint feature Feature, performs IoM processing ...

Abstract

The invention discloses a biological characteristic authentication method under a cloud environment with privacy protection. The authentication process of the biological characteristics is respectively put into three different servers, and the revocable biological characteristics are generated in the revocable characteristic server by using the revocable palm print competition code characteristicidentification method of the IoM, so that the safety of the biological characteristics is ensured; the pseudorandom sequence is processed by using a cyclic exclusive-OR algorithm in the pseudorandom characteristic server to obtain a pseudorandom identity characteristic; and finally, in the identity authentication server, identity authentication is realized by comparing the pseudo-identity characteristics. By using the algorithm, the security of biological characteristics can be ensured, the security and privacy of the template can be ensured, and remote cloud identity authentication can be realized.

Description

technical field [0001] The invention relates to the field of biometric authentication, in particular to a biometric authentication method in a cloud environment with privacy protection. Background technique [0002] Today, biometrics are a common application for identity management. However, if the biometric template is only stored unprotected, it will cause some security and privacy issues when the biometric template is compromised. For example, an attacker could use a stolen template to gain unauthorized access to the system. In addition, due to the irrevocability of biometrics, once leaked, the biometrics will no longer be valid. Therefore, biometric template protection is crucial for biometric recognition systems. In general, biometric template protection falls into two broad categories: revocable biometrics and biometric cryptosystems (or biometric encryption). [0003] It is understood that the security risks of biometric encryption technologies such as fingerprint...
