Method and device for recognizing handwritten signature and starting system by handwritten signature

Abstract

The invention discloses a method for recognizing a handwritten signature, which comprises the following steps: acquiring signature data and preprocessing the same; extracting global characteristic information and local characteristic information of the signature data; matching the global characteristic information with the global characteristic information of a preset signature sample and judging whether a first preset condition is satisfied; and if the first preset condition is satisfied, matching the local characteristic information with the local characteristic information of the preset signature sample; if the first preset condition is not satisfied, returning to the result of the failed matching directly; and if the matching result of the local characteristic information satisfies a second preset condition, returning to the result of the successful matching. The method can improve the efficiency and the accuracy of handwritten signature recognition so that a user can obtain a better using experience.

Description

technical field [0001] The invention relates to the technical field of identification, in particular to a handwritten signature recognition method, a handwritten signature recognition device and a handwritten signature boot system. Background technique [0002] Handwritten signature recognition technology is a technology that compares the image, stroke order, speed and pressure of handwritten signatures with real signature samples by computer to identify the authenticity of handwritten signatures. This technology is internationally recognized as an identity authentication method that is more easily accepted by the public, and it is also a frontier topic in the field of computer identity identification. [0003] In practice, this handwritten signature recognition technology can be used to solve the system security and confidentiality problems in computer equipment. Usually, the realization of this handwritten signature recognition technology requires pre-stored real signature...

AI Technical Summary

Problems solved by technology

[0012] It can be seen that, in the process of handwritten signature recognition, the above scheme adopts the method of overall matching for each signature input by the user. A matching authentication process needs to go through the similarity calculation step, the weighted average calculation step of the input signature, and the registered The authentication / rejection judgment step can only be entered after the weighted average calculation step and the weighted average deviation calculation step of the signature are processed. The matching process is too complicated, and it also needs to occupy more system resources in practice, resulting in low matching efficiency. It will definitely affect the recognition efficiency of handwritten signatures
