Signature forgery detection device and method, computing equipment and storage medium

Abstract

The invention discloses a signature forgery detection device and method, computing equipment and a storage medium, the device comprises an interaction layer, an interface layer and a service layer, the service layer comprises a receiving module suitable for receiving a to-be-detected signature picture scheduled by the interface layer and a character mark of the to-be-detected signature picture; a first segmentation module which is suitable for carrying out single character segmentation processing on the to-be-detected signature picture to obtain each to-be-detected character picture; a first feature extraction module which is suitable for extracting a hash code of each to-be-detected character picture as a character picture feature; a comparison module which is suitable for querying in a character feature library according to the character marks, comparing the character picture features of the character pictures to be detected with the queried character picture features, and if the character picture features of at least one character picture to be detected are similar to the queried character picture features, determining that the to-be-detected signature picture is a forged signature picture. The device can improve the precision and accuracy of detecting the forged signature picture.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a signature forgery detection device, method, computing equipment and storage medium. Background technique [0002] With the rapid development of social information technology, handwriting input has become a natural and convenient form of human-computer interaction. In the digital age, handwritten signatures on smart devices (mobile phones, tablet) have been used in more and more agreement signing scenarios, such as: payment voucher signature, bank business processing confirmation signature, paperless business work order Signature, etc., the user signs his name on the handwritten signature device to confirm the business information. While safeguarding the legitimate rights and interests of both Party A and Party B, it improves the efficiency of business handling and brings convenience to people's production and life. However, when the client collects the user's signatur...

Problems solved by technology

[0005] However, the inventor found in the process of realizing the present invention that although the handwritten character recognition method can recognize the text content, it cannot perform adaptive update on the user's handwritten characters, and cannot effectively monitor whether there is a feature almost identical to the handwritten character. text template, so there is no basis to judge whether the signature is forged; and the anti-counterfeiting of the page covering invisible signature certificate needs to be printed on the signature medium on the certificate, etc., using color-matched ink, which depends on printing technology and paper media, and the operator's industry. The paper signature scenario is not suitable
