Embodiment Construction
[0042] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0043] The online handwriting authentication method based on finger information of the present invention comprises the following two stages:
[0044] In the registration stage, several handwriting feature information of the user are extracted, and the handwriting handwriting information set is separated from several handwriting feature information for training to obtain the first authenticator, and the static information set of the writing finger in contact with the writing plane is trained to obtain the second authentication device. Finally, the two authenticator parameters are stored in the database.
[0045] In the authentication phase, the user to be tested submits his claimed user identification number and test handwriting feature information, and the authentication system will input the two types of feature information separate...

The invention discloses an online handwriting authentication method and system based on finger information. The method includes: registering the handwriting feature information of the user, extracting the handwriting feature information of the user to be tested, and performing authentication. authentication, otherwise the authentication is rejected, the handwriting characteristic information is two types of characteristic information including handwriting handwriting information in a writing process and static information of fingers in contact with the writing plane acquired at the same time. The present invention separates and calculates the handwriting information written by the finger from the handwriting feature information acquired at the same time, and performs multi-feature fusion for the finger static information of the finger in contact with the writing plane for authentication, avoiding the use of independent features in the prior art The security problems brought about by the collection and authentication are improved, thereby improving the overall security of the authentication system.
Description
technical field [0001] The invention relates to an online handwriting authentication method, in particular to an online handwriting authentication method and system based on finger information. Background technique [0002] With the rapid development of e-commerce, the problem of user identity authentication in the network environment has become increasingly prominent. Handwriting is naturally suitable for applications in the network environment because of its various characteristics. However, due to the inherent differences between real handwriting and the threat of potential imitation of handwriting with high similarity, the current online handwriting authentication methods cannot fully meet the security requirements of application systems. Therefore, people think of fusing handwriting with other physiological features to improve the overall security of the system authentication system. In the Chinese Patent Publication No. CN1794266A, entitled "Identification and Authen...
