User identity verification method and system, electronic equipment and storage medium

Abstract

The invention provides a user identity verification method and system, electronic equipment and a storage medium, and can be applied to the field of computers, the field of big data or the field of finance. The method is applied to a privacy computing platform and receives target user information of a target user; respectively acquiring a first target encrypted biological characteristic fragment, a second target encrypted biological characteristic fragment and a third target encrypted biological characteristic fragment corresponding to the target user id from each security node; wherein each encrypted biological characteristic fragment is generated by utilizing the biological characteristic of the corresponding user and the user id; according to the first target encrypted biological characteristic fragment, the second target encrypted biological characteristic fragment, the third target encrypted biological characteristic fragment and the encrypted biological characteristics of the target user, calculating the verification similarity of the target user; if the verification similarity is greater than a preset similarity threshold, determining that the identity verification of the target user is passed; and if the verification similarity is not greater than a preset similarity threshold, determining that the identity verification of the target user is not passed.

Description

technical field [0001] The present invention relates to the field of computer technology, and more particularly, to a method, system, electronic device and storage medium for user authentication. Background technique [0002] With the continuous development of computers, more and more businesses are carried out by banking institutions. In order to ensure the security of banking business, users can be authenticated when they handle banking business. [0003] In the prior art, the user's biometrics can be collected in advance, so that when the user comes to the bank for banking business, the user's current biometrics are collected, and the currently collected biometrics are compared with the previously stored biometrics. However, in this comparison method, if the user is maliciously attacked by a third party when obtaining the user's biometric features or performing identity verification, it is easy to cause data leakage, and it is impossible to provide comprehensive privacy a...
