Online signature identification method and system

Abstract

The invention discloses an online signature identification method and system. In different application occasions of electronic signature identification, contradiction between accuracy and cost is solved. The method comprises the steps that electronic signature sample collection is carried out by taking population as a target; when each person in the population is registered, multiple samples are collected to form a sample library of the population; whether a specified signature is corresponding to a designated person object is identified; if the specified signature is not corresponding to the designated person object, an identification process is ready to start; before identification starts, an identification algorithm is adjusted according to a preset straying rate and false rejection rate; and the identification process is carried out to find out the real signer from the sample library of the population. According to the invention, a flexible electronic signature judging method is ultimately realized; a reasonable work method is selected according to different application occasions; and high identification accuracy or low cost is realized.

Description

technical field [0001] The invention relates to a method and system capable of identifying computer online signature data. Background technique [0002] The "Electronic Signature Law of the People's Republic of China" was passed by the Eleventh Session of the Standing Committee of the Tenth National People's Congress of the People's Republic of China on August 28, 2004, and came into effect on April 1, 2005. The law is considered China's first legislation in the sense of a true e-commerce law. Because since the United Nations promulgated the "Model Law on Electronic Commerce" in 1996, e-commerce legislation in various countries in the world has been in full swing. Some countries have promulgated e-commerce laws or transaction laws, and some countries have promulgated electronic signatures or digital signatures. Two legislative approaches. However, my country's e-commerce legislation was finally introduced under the guidance of the national informatization strategy. It can ...

Problems solved by technology

[0004] Due to the complexity of the actual situation, it is inevitable that there will be deviations in judgment in the identification of electronic signatures, and the tolerance for identification deviations in different application environments is also different. In some important occasions, the accuracy of identification is higher, but The improvement of identification accuracy will inevitably increase the cost of identification time and workload. However, in some applications with a large amount of identification and low accuracy requirements, a large amount of cost caused by high accuracy is likely to Unbearable
