Abstract

The invention relates to a user identity authentication method and device, computer equipment and a storage medium in the field of information security. The method comprises the steps of acquiring first information corresponding to a first terminal of a logged-in user account, and extracting multi-dimensional features corresponding to the first terminal from the first information; associating themulti-dimensional feature corresponding to the first terminal with the user account; when a password-free payment request sent by a second terminal logging in the user account is received, obtaining multi-dimensional features corresponding to the second terminal; calculating a similar distance between the multi-dimensional feature corresponding to the first terminal and the multi-dimensional feature corresponding to the second terminal; and if the similarity distance exceeds a threshold value, determining that the user identity of the second terminal does not pass the verification, intercepting the password-free payment request, and sending corresponding prompt information to the first terminal. By adopting the method, the security of the password-free payment function can be effectively improved.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a user identity verification method, device, computer equipment and storage medium. Background technique [0002] With the development of Internet technology and the popularization of mobile terminals, mobile payment has become an important payment method in people's daily life. With the increasing use frequency of mobile payment, in order to simplify the operation of mobile payment, a variety of payment software has also introduced the function of password-free payment, that is, when users make payment on mobile terminals, they can complete the payment without entering a password. Although the password-free payment function provides convenience for the user, if the user account is stolen, it will bring great losses to the user. Therefore, how to improve the security of the password-free payment function has become a technical problem to be solved at present. Conte...
