Biological characteristic template protection method with safety threat monitoring capability

Abstract

The invention discloses a biological characteristic template protection method with the safety threat monitoring capability and relates to terminal password equipment, a certificate management system, a biological certificate signing service, a template honey pot monitoring service and a certificate certification service. The method is characterized by comprising a biological secret key generation and template honey pot forging, a template parameter secret storage and template honey pot publicity, a feature rapid matching and recognition of a biological certificate, a template parameter retrieval and template threat detection, a biological secret key recovery and on-line signature application. Based on the above manner, the safety threat of the biological template can be monitored in real time based on a honey pot and a certificate. Therefore, the template attack problem of the biological template based on the publicity of the digital certificate is effectively solved. As a result, the novel characteristic of the biological characteristic encryption application of the online signature and offline verification is realized. Meanwhile, safety targets, such as identifiable identity of the biological characteristic application, the non-repudiation of the signature, the non-tampering of data and the like, are achieved.

Description

Technical field [0001] The method of the invention belongs to the application field of biological identification, is a combination of biological feature encryption technology and a public key infrastructure PKI certificate system, and is suitable for network security applications such as electronic signatures and identity authentication based on biological features. Background technique [0002] With the rapid development of Internet technology, especially in the context of the application of big data processing in the current cloud computing environment, while people are enjoying the convenience of information networks, network security issues have become increasingly prominent. The rapid development of biometric encryption technology in the past ten years, as a new direction and new application of the integration of biometric identification and cryptography, provides an opportunity to solve the key management problem in the Internet environment. At the same time, because o...
