Fingerprint and Voiceprint Dual Authentication Method

Abstract

The invention discloses a fingerprint and voiceprint dual-authentication method and a fingerprint and voiceprint collector. The dual-authentication method includes: collecting a fingerprint and triggering voice collection at the same time; performing fingerprint recognition on the collected user fingerprint to obtain a fingerprint recognition score, performing voiceprint recognition on the collected user voice to obtain a voiceprint recognition score; performing integrated computation on the fingerprint recognition score and the voiceprint recognition score to obtain an integrated authentication score; judging a user identity according to the integrated authentication score; if the integrated authentication score is higher than or equal to a preset threshold, considering that both the fingerprint and the voiceprint come from a claimed user himself and the authentication passes, otherwise, considering that the authentication fails in passing. The fingerprint and voiceprint collector comprises a master control circuit which is connected with a fingerprint collector, a microphone and a fingerprint and voiceprint colligative authentication system. Fingerprint recognition and voiceprint recognition are combined to perform dual authentication, and accurately, safety and reliability of local and remote identity authentication are improved greatly by the dual-authentication mode.

Description

technical field [0001] The invention relates to a fingerprint and voiceprint dual authentication method, which belongs to the technical field of computer authentication services. Background technique [0002] In the field of biometric identification, providing one's own biometrics for identification is called self-identification, and biometric identification includes fingerprint identification, voiceprint identification, and the like. [0003] As an important biometric identification technology, fingerprint recognition has been applied to many occasions of identity authentication, but it can be found from the actual implementation that the existing fingerprint recognition technology is not very good for various intrusion identification, and it is not very good for security. In occasions with high requirements, there are certain risks in using fingerprint recognition alone for identity authentication. In addition, with the continuous advancement of technology, the emergence ...

[0003] As an important biometric identification technology, fingerprint recognition has been applied to many occasions of identity authentication, but it can be found from the actual implementation that the existing fingerprint recognition technology is not very good for various intrusion identification, and it is not very good for security. In occasions with high requirements, there are certain risks in using fingerprint recognition alone for identity authentication

In addition, with the continuous advancement of technology, the emergence of fingerprint cover (also known as fingerprint film) has greatly restricted the application of fingerprint identification technology, especially in the case of remote identity authentication, it is difficult to determine whether a fingerprint cover is used. This undoubtedly has a serious impact on the correctness and security of identity authentication.
