A signature authenticity identification system for signature pen

Abstract

The invention discloses a signature authenticity identification system oriented to a signature pen. It includes information entry module, sample database module, feature model building module, feature extraction module, similarity measurement module and identification and output module. The identification process is that the feature model building module performs spatial modeling on the feature information collected by the information input module, and extracts the feature parameters of the relationship between the writing level pressure and the pen-holding posture with time and the length of the handwriting from the spatial geometric model, and constructs a matrix input system. The average information entropy of each type of feature is used to calculate its weight coefficient, and the comprehensive feature similarity between the information to be tested and the sample information is calculated by combining the method of matrix similarity measurement. In the identification and output module, the comprehensive similarity is compared with the similarity threshold corresponding to different signers, and the authenticity of the signature is verified and the final identification result is output. The signature verification and identity verification method proposed by the invention has objective and stable results.

Description

technical field [0001] The invention relates to a signing pen-oriented authenticity identification system of a user's signature, which belongs to the technical field of digital image processing and signature identification. Background technique [0002] The 21st century is the information age. Key industries and enterprises such as finance, medical care, government and public utilities are all covered by big data. The emergence of various digital products has brought people efficient and convenient lives and greatly improved people's lives. quality, but at the same time, it inevitably brings many problems in information security. The identity authentication of personnel involved in daily transactions and affairs is one of the problems that needs to be solved urgently. With the in-depth research on the identification technology based on human biometrics, the human biometrics currently investigated by researchers have begun to shift from inherent characteristics such as perso...

[0002] The 21st century is the information age. Key industries and enterprises such as finance, medical care, government and public utilities are all covered by big data. The emergence of various digital products has brought people efficient and convenient lives and greatly improved people's lives. quality, but at the same time, it inevitably brings many problems in information security

However, at present, no matter whether it is theoretical research or practical application, no researchers have set their sights on these features obtained from signature pens, and there is no research on signature authentication technology for signature pens.
