Kind Code:
A1
Abstract:
The present application discloses a handwritten password-based identity authentication method and device. Wherein, the method comprises: receiving a password to be verified that a user enters by handwriting; extracting password information to be verified of the password to be verified, wherein the password information to be verified comprises characters to be verified and features to be verified in the password to be verified, wherein the features to be verified comprise at least one of a character image to be verified corresponding to the characters to be verified and a handwriting behavior feature to be verified corresponding to the characters to be verified; if the similarity between the password information to be verified and pre-stored preset password information of a preset password set by user handwriting meets a first preset condition, determining whether the identity verification is successful. The method can judge whether the image handwritten by the user is a password image, judge whether it is the user's own handwriting action through the behavior, and perform the verification in three aspects of the content, the image and the action, which greatly improves the accuracy of user identity verification.
