Embodiment Construction

[0018] The above and other objects, features and advantages of the present invention will become apparent from the following description taken in conjunction with the accompanying drawings of the present invention.

[0019] Voice is the most basic and convenient way of communication and transaction for human beings. The voice information generated by users using the authentication system can contain both user identity information and user personal wishes information. The present invention makes full use of the advantages of the voiceprint authentication technology, especially the text-independent voiceprint authentication technology, and at the same time combines the method of confirming the pronunciation status of a real person present to improve the overall security of the authentication equipment, and confirm the authenticity through the interactive authentication process. The pronunciation is in a state of clear consciousness.

Abstract

The disclosed sound-groove identification device to validate whether the actual person present comprises: a voice input device to receive the user voice, a sound-groove identification device to compare the input voice and the model and validate user ID, a field identification device to compare the input imitative voice and random prompt voice selected from the prepared voice set and determine the actual person pronounces in place, and a decision device to decide whether user presents according to said results. This invention rejects the personator effectively and improves the security of sound-groove identification.

Description

technical field [0001] The invention relates to a voiceprint authentication device and method, in particular to a voiceprint authentication device and an authentication method for verifying the presence of a real person. Background technique [0002] With the progress of social economy and the development of information technology, people have more and more demands and dependence on information security and identity authentication technology. Traditional identity authentication methods are mainly based on passwords, which have the advantages of simplicity and speed, but have obvious shortcomings, for example, they are easy to be forgotten, guessed or stolen, etc. Once this happens, it is very difficult May cause great trouble or loss to the user. [0003] The root of the deficiency of the password verification method is that it has no internal connection with the holder itself. If any other person obtains and tries to authenticate with the person's password, the system will...
