Document Type and Number:

WIPO Patent Application WO/2021/043014

Kind Code:

A1

Abstract:

The present invention relates to an identity authentication method based on a biometric feature, and a system thereof. The method comprises: obtaining, by means of a base station associated with a user entering a specified area, mobile terminal numbers of all users entering the specified area, so as to generate a first mobile terminal number list; identifying a biometric feature of the user, and obtaining, on the basis of a pre-established binding relationship between biometric features of the users and the mobile terminal numbers, a second mobile terminal number list composed of n mobile terminal numbers having the highest similarity with the biometric feature; and comparing the first mobile terminal number list with the second mobile terminal number list, if the intersection of the two is one mobile terminal number, determining that the user of the mobile terminal number is a user whose identity authentication is successful, and if the intersection of the two is greater than one number, determining that the user of a mobile terminal number, with the highest biological feature similarity, in the intersection is a user whose identity authentication is successful. According to the present invention, the range of facial recognition N can be reduced, and a user only need carry a mobile phone to complete 1 : N facial recognition without additional operations.
