Abstract

The invention relates to artificial intelligence, and provides an identity verification method and device, equipment and a storage medium. The method can obtain to-be-verified audio and environment audio, perform loudness compensation processing on the to-be-verified audio and the environment audio to obtain first verified audio and noise audio, remove the noise audio from the first verified audio to obtain second verified audio, and perform compression processing on the second verified audio to obtain a first audio feature. The similarity between the first audio feature and all preset features are calculated to obtain a first confidence value, if the first confidence value is greater than a first preset threshold and the first confidence value is less than a second preset threshold, the similarity between the second audio feature and all preset features is extracted and calculated to obtain a second confidence value, and if the second confidence value is greater than the second preset threshold, it is determined that the identity verification request passes verification. According to the invention, the accuracy of identity verification can be improved. In addition, the invention also relates to a blockchain technology, and all the preset features can be stored in the blockchain.

Description

technical field

[0001] The present invention relates to the technical field of artificial intelligence, in particular to an identity verification method, device, equipment and storage medium. Background technique

[0002] In a service system with query permission requirements, it is necessary to verify the identity information of the caller before authorizing the query of information within the scope of permission. At present, the personal information such as the ID card manually entered by the caller is mainly verified through the background. However, this method is likely to pass the identity verification after the personal information is leaked, resulting in information leakage in the service system.

[0003] In order to improve the security of identity verification, the method of remotely verifying identity through voiceprint has also emerged. However, due to the influence of environmental noise and the low remote voice of the caller, it is impossible to accurately ident...
