Signature authenticity identification system for signature pen

Abstract

The invention discloses a signature authenticity identification system for a signature pen. The system comprises an information entry module, a sample database module, a feature model building module,a feature extraction module, a similarity measurement module and an identification and output module. The identification process is that the feature model building module carries out spatial modelingon feature information collected by the information entry module, the feature parameters of relationship of two types of features including writing horizontal pressure and a holding pen posture withtime and handwriting length are extracted from a spatial geometric model, and a matrix input system is constructed. The average information entropy of each type of features is used to calculate a weight coefficient, and a comprehensive feature similarity of information to be measured and sample information are calculated with the combination with a method of matrix similarity measurement. In the identification and output module, the comprehensive similarity and similarity thresholds corresponding to different signers are compared, and the authenticity of a signature is identified and a final authentication result is outputted. The invention provides signature authentication and identity authentication methods, and the result is objective and stable.

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...
