An identity authentication method and user terminal

Abstract

The embodiments of the invention disclose an identity authentication method and a user terminal. The method comprises the steps of detecting whether the matching degree of the input fingerprint information with the pre-acquired preset fingerprint information is higher than a preset first threshold value or not after a user terminal receives the fingerprint information input by a user; on the condition that the matching degree of the input fingerprint information with the pre-acquired preset fingerprint information is higher than the preset first threshold value, outputting a first prompt message for prompting the input of the voiceprint information; receiving the input voiceprint information input in response to the first prompt message; detecting the matching degree of the input voiceprint information with the pre-acquired preset voiceprint information is higher than a preset second threshold value or not; on the condition that the matching degree of the input voiceprint information with the pre-acquired preset voiceprint information is higher than the preset second threshold value, successfully completing the identity authentication process. The embodiments of the invention can increase the security of identity authentication.

Description

technical field [0001] The invention relates to the field of security technology, in particular to an identity authentication method and a user terminal. Background technique [0002] With the rapid development of electronic technology and the rapid popularization of user terminals, the functions of user terminals are becoming more and more perfect. For example, the user can use the user terminal to access external network data resources, take pictures, and contact with friends. However, when the user terminal brings endless convenience to the user, it also brings concerns to the user, such as the security of data resources stored in the user terminal. In practical applications, in order to improve the security of data resources stored in user terminals, identity authentication is required before viewing data resources stored in user terminals, and corresponding data resources can be viewed only after identity authentication is successful.

Problems solved by technology

[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 security of identity authentication.
