Authentication method, system and apparatus

Abstract

The present invention provides an authentication method. The method comprises: receiving to-be-authenticated audio; performing signal-to-noise ratio estimation on the to-be-authenticated audio; and determining whether the signal-to-noise ratio of the to-be-authenticated audio reaches a first threshold, if yes, detecting whether content of the to-be-authenticated audio is consistent with content of corresponding original audio, and if yes, determining that the authentication is passed, or otherwise, determining that the authentication is not passed. With the adoption of the authentication method, an environmental impact can be reduced and speech recognition accuracy can be improved, so that the accuracy of authentication is improved and misjudgments are reduced. Furthermore, another authentication method and an authentication system and apparatus are provided.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a verification method, system and device. Background technique [0002] In many application scenarios, it is necessary to verify whether the user is a "real human being". Captcha is a public automatic program that is currently effective in distinguishing whether the user is a computer or a human. Users need to answer the verification questions raised by the website service provider before they can be considered human beings by the terminal and continue to enjoy the service. Practice has proved that the verification method based on verification codes can greatly reduce common network security risks such as malicious brute force cracking passwords, swiping tickets, flooding forums, and swiping pages. [0003] The read-write verification code is the most common verification code. Usually, the server provides a picture containing a string and requires the user to enter the...
