Hand-wirte signature recognition program, method and device

Abstract

The invention provides a handwritten signature authentication program, method and device. When registering a signature, input a Japanese signature such as "Fujitsu" ("Fujitsu") or an English signature such as "Fujitsu" n times through the input device of the input device of a signature authentication system, and calculate handwriting shape, writing speed, and writing acceleration and elements of writing pressure. Set the combination of nC2 for each element of the input data n times, get the inverse of each similarity, calculate the average value of the similarity of each element, determine the weight of each similarity according to the average value, and calculate the four elements and define it as the total similarity of the registered signatures. During the authentication process, the signature data to be compared is input / output m times. The total similarity of the signatures to be compared can be obtained in the same way.

Description

technical field [0001] The present invention relates to a handwritten signature authentication program, method and device. The handwritten signature authentication program, method and device can improve the matching accuracy by preprocessing or postprocessing the matching data of the handwritten signature. Background technique [0002] Usually, an authentication method based on the feature quantity of a handwritten signature is used as a biometrics authentication method (a method of authenticating a user based on a person's physical characteristics such as fingerprints, retina, iris, voiceprint, etc., when people access a network or start a personal computer) ) is well known. In this case, the matching check is performed by comparing feature quantities of handwriting shape, writing speed, writing acceleration, writing pressure, etc. between the handwritten signature signed at the time of registration and the handwritten signature signed when the user is authenticated.

AI Technical Summary

Problems solved by technology

Therefore, in the conventional common comparison logic obtained from the total value of the similarity of the characteristic quantities of the respective writing components, the above-mentioned deviation characteristics depending on each individual are ignored, and an optimal comparison result for each individual cannot be obtained.

Therefore, someone who should be authenticated may be denied by mistake, or an improper person may be authenticated by mistake
