Based On C/S Mode To Research Of On-line Handwriting Authentication

With the rapid development of information technology to experience all sides of life brought great convenience, but also can cause some problems at the same time, the most obvious is the problem of information security, and to real-time accurate judgment particularly major personal identity authentication. For computer network, computer control system, mobile communication, such as requiring authentication, research and explore the mechanism of on-line handwriting signature verification, to develop efficient and fast on-line handwritten signature authentication feature extraction and recognition algorithm, realize sign the handheld terminals(smartphone) to achieve the purpose of authentication.For traditional authentication of password, IC card, id card, those may be lost or stolen, but handwritten signature authentication without this problem and is suitable for the current widespread use in checks, contracts, the receipt and sign your name on e-commerce and other fields for identification and recognition. By hand-held terminals(smartphone) signature to extract characteristic information, then save in the computer database. When being used by that time, by person signature to sign words and deposited text in the database information characteristics compared to identify. Here used the FFT, DTW, HMM and dynamic methods of deep after comparing. Based on the theoretical research has developed a sign system for identification authentication. Experiment proved that each matching method has its advantages and disadvantages, and the selection of signature matching is the key to the accuracy of the algorithm combination design, using the method of dynamic deep after fitness can better to simplex accelerated, opposite to the random search exploration, to keep its time and space to two or more things, improve the matching efficiency.Based on physical characteristics and behavior characteristics, its obvious than the traditional way to identify safety and convenient, and has good security, the advantages of easy to carry, not easily lost and forgotten. So in government, finance, transportation, etc have broad application prospects. Therefore, research on handwritten signature certification not only has special theoretical significance, and has important application value.
