Multi-biological feature authentication or identification-based method and system

Abstract

The invention discloses a multi-biological feature authentication or identification-based method and system. The method comprises the following steps of: acquiring a plurality of groups of biologicalfeatures of a first target object set and obtaining biological feature values; in order to recognize each biological feature, distributing a biological feature identifier for each biological feature;establishing a mapping relationship between each biological feature identifier and a preset mapping code set; and after an authentication code or an identification code formed by mapping codes corresponding to a part or all of the biological feature identifiers is determined, carrying out authentication or identification according to the authentication code or the identification code. According tothe system and method, the problem that biological features of natural persons are abused as the biological features of the natural persons are leaked or the using of the biological features of the natural persons is not controlled by the natural persons is avoided, the confidentiality and verifiability of safety information are improved, and the non-repudiation is improved at the same time.

Description

technical field [0001] The present invention relates to the field of information security, in particular to a method and system based on multiple biometric feature authentication or identification. Background technique [0002] In modern society, with the rapid development of computer and network technology, information security has shown unprecedented importance, and identity verification is a necessary prerequisite to ensure system security. In financial, national security, judicial, e-commerce, e-government and other application fields, accurate identification is required. Currently widely used traditional methods such as certificates, personal identification numbers, and passwords to confirm personal identities are facing severe challenges and are increasingly unsuitable for the development of modern technology and social progress. Biometric identification is a science of identification and / or individual verification by using the unique physiological and behavioral char...

Problems solved by technology

[0003] However, the problem that cannot be ignored is that the biometric feature itself cannot be changed. If the characteristic value of the biometric feature is used for identification and authentication of personnel, once the biometric feature is leaked, it is easy to clone the leaked biometric feature to achieve forgery. or tampering for identification or authentication purposes

In addition, if criminals restrict the operator, for example, make the operator unconscious or coerce the operator, it is easy to manipulate the operator's body to successfully complete the collection of biometrics

In this way, information security cannot be guaranteed
