Voice-print authentication system having voice-print password picture prompting function and realization method thereof

Abstract

The invention discloses a voice-print authentication system having a voice-print password picture prompting function, which comprises a password establishing module, a voice recognition module and a voice-print recognition module; the password establishing module is connected with a server, a password is a random password or consists of a random password and a fixed password, the server generates the random password, and the random password is displayed on a login terminal of a user in a picture format; the voice recognition module is used for analyzing content of voice provided by the user and for performing the mode matching of the voice content provided by the user and the password content generated by the server, if the voice content is not matched with the password content, the password provided by the user is proved not to satisfy the requirement, and if the voice content is matched with the password content, the voice-print recognition module is entered; and the voice-print recognition module is divided into a register unit and a test unit, wherein a speaker model is established in the register unit, and the test unit calls the speaker model to analyze the characteristics of the provided voice in test and to execute the confirmation judgment so as to determine to accept or to refuse. In addition, the invention also discloses a realization method of the system. Due to the adoption of the system and the method, the security of the voice-print authentication can be improved.

Description

Technical field [0001] The present invention relates to a voiceprint authentication system, in particular to a voiceprint authentication system prompted by a voiceprint password picture; in addition, the present invention also relates to a realization method of the voiceprint authentication system prompted by a voiceprint password picture. Background technique [0002] Currently, password-based identity authentication systems usually need to set different passwords for different objects for security, which increases the user's memory burden and difficulty in use. The voiceprint recognition method is adopted to confirm the identity through the voice characteristics of the user, and only the voice of the real user can pass the authentication. In order to reduce the user's memory burden, the server provides text content (such as idioms and number strings), and the user only needs to read the corresponding content as required. However, there are various security risks on the network...

Problems solved by technology

However, there are various security risks on the network. If the attacker directly obtains the text content, it is possible to carry out various attacks, such as threatening the user's password security by splicing user voices and stealing user voices.
