Identity authentication method, apparatus, and identification terminal

Abstract

The invention provides an identity authentication method, an apparatus and an identification terminal. The method comprises: receiving motion information and finger pressure information sent by the motion sensing signature pen, wherein the motion information and the finger pressure information are collected by the motion sensor module when a user signs with the motion sensing signature pen; extracting a motion eigenvalue from the motion information and extracting a pressure eigenvalue from the finger pressure information; judging whether the motion eigenvalue is greater than a preset maximum authentication threshold value, and judging whether the pressure eigenvalue is within a preset authentication range; if the motion eigenvalue is larger than the preset maximum authentication thresholdand the pressure eigenvalue is within the preset authentication range, the user identity authentication being confirmed to be passed, so as to reduce the probability that the signature is forged and improve the accuracy of the user signature recognition.

Description

technical field [0001] The invention relates to the technical field of signature pens, in particular to an identity authentication method, device and identification terminal. Background technique [0002] With the rapid development of information technology, various applications of the Internet have gradually penetrated into all aspects of our lives. While the Internet has brought huge economic benefits and convenience to society, it has also brought unprecedented challenges to network security. Therefore, real-time and accurate personal identity authentication is very important. Handwritten signature authentication is an effective method in personal identity authentication technology. Compared with other biometric features, it has the advantages of non-invasiveness and easy acceptance. [0003] At present, the handwritten signature recognition of paper documents is to collect paper signature pictures through scanners, cameras and other input devices, and compare the paper...
