Abstract

The invention provides handwriting input equipment and a data acquisition method, and belongs to the fields of computer information and electronics. The handwriting input equipment simultaneously acquires handwriting information and palm side surface information of a pen holding hand, which are generated in a writing process. An information acquisition device of the equipment comprises a side palm print sensor, a display screen and an antenna array, wherein the antenna array is located below the outside of the display screen; the side palm print sensor is located above the outside of the display screen, and used for acquiring two-dimensional image information of a side palm print; the antenna array is used for acquiring the handwriting information; and the display screen is used for displaying handwriting track information, and presents the handwriting track information to a user. Compared with acquisition of handwriting and other physiological characteristics, the attack difficulty can be increased effectively by simultaneously acquiring the handwriting information and palm side print information of the pen holding hand, which are generated in the writing process, so that the security of a certification system is improved.

Description

technical field [0001] The invention relates to the fields of computer information and electronics, in particular to a handwriting input device including palm side surface 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 authentication system. In the Chinese Patent Publication No. CN1794266A, entitled "Identification and Authentication Method ...
