Abstract

The embodiment of the invention provides a user identity authentication method and device, a user terminal and a server. The method comprises the steps of obtaining signature sensor data collected bya sensor of a user terminal in the current user signature process and handwriting screenshot data formed by a user in the signature process; based on the signature sensor data and the handwriting screenshot data, respectively identifying user identities; and if the verification results based on the signature sensor data and the handwriting screenshot data are legal, passing the identity authentication. According to the invention, the behavior characteristics of the handwriting process and the biological characteristics of the handwriting are fused for use, so that the identity authentication of the handwritten signature is carried out more accurately, and the identity authentication speed can be improved.

Description

technical field [0001] The present invention relates to the technical field of artificial intelligence, in particular to a user identity authentication method, device, user terminal and server. Background technique [0002] Currently, there are various methods for authenticating a user. For example, a set of parameters is selected from the obtained handwritten signature to represent the signature, and the authenticity of the signature to be verified is judged by comparing the parameters of the training signature and the signature to be verified. These parameters include the horizontal and vertical coordinates, displacement, velocity and acceleration of the signature, as well as the average value, variance, maximum value and minimum value of these parameters. [0003] But existing technology has the following defects: [0004] First, signature identity authentication needs to be performed based on a dedicated handwriting device (special tablet and stylus); [0005] Second,...
