Embodiment Construction

[0031] The invention provides an identity verification system and method based on voiceprint recognition, which performs voiceprint verification and semantic verification on voice information input by a user at a terminal, thereby confirming the user's identity. Through the present invention, the user does not need to memorize any password or question answer, not only the operation is convenient, but also the problem of using recording to crack in the existing voiceprint verification system can be effectively avoided.

[0032] Such as figure 1 Shown is a schematic diagram of the first embodiment of the identity verification system of the present invention. The system includes a transceiver unit 12 , a semantic verification unit 14 , a voiceprint verification unit 15 and a voiceprint feature library 16 .

[0033] The voiceprint feature database 16 is used to store one or more voiceprint features, wherein each voiceprint feature corresponds to a user. When storing, each voicep...

Abstract

The invention relates to an identity authentication system which comprises a voiceprint feature library, a receiving and sending unit, a semanteme authentication unit and a voiceprint authentication unit, wherein the voiceprint feature library is used for storing one or more voiceprint features, and each voiceprint feature corresponds to an account; the receiving and sending unit is used for sending one or more characters to terminals and receiving the input accounts and voice signals from the terminals; the semanteme authentication unit is used for confirming that the identity authenticationfails when the voice signals which are received by the receiving and sending unit are not matched with the pronunciations of the characters which are sent to the terminals; and the voiceprint authentication unit is used for confirming that the identity authentication fails when the voice signals which are received by the receiving and sending unit are not matched with the voiceprint features corresponding to the accounts in the voiceprint feature library. The invention also provides a corresponding method. By combining the voiceprint authentication with the semanteme authentication, the invention realizes safe identity authentication and is convenient for users to operate.

Description

technical field [0001] The present invention relates to the field of safety verification, and more specifically relates to a system and method for identity verification combined with human physiological characteristics. Background technique [0002] With the advent of the information age, digitization has increasingly affected people's daily life, such as using the Internet to browse or send and receive information, online shopping through the Internet, and currency payment through online banking. In order to ensure the security of personal information in digital life, it is necessary to accurately identify personal identities in digital life. [0003] Currently the most commonly used method of personal authentication is a password. In this authentication method, the user must keep in mind the password, such as the user's bank account password, credit card password, network login account password, and the like. Since different applications have different requirements for p...
