指纹鼠标的开发

Developing of Fingerprint Mouse

指纹鼠标开发目的是将具有唯一性、稳定性的生物特征用于计算机用户身份识别 ,加强计算机信息安全。核心是把现场采集的指纹特征与存储的指纹通过可靠的匹配算法验证用户身份。根据鼠标内部较大空间、贴片式指纹识别芯片及微处理器体积很小特点 ,开发出集鼠标与用户身份识别功能于一体的“指纹鼠标” ,既方便快捷、又唯一可靠。主要介绍“指纹鼠标”技术基础、方案设计、开发要点。

The mouse is developed with the purpose of providing reinforcement of database s ecurity for computer users, whose validity can be verified by taking advantage o f the fingerprint identity, which is the unique, immutable biological characteri stic of human body. A robust one-by-one matching algorithm, rendering between pr essured data and field acquisitions of finger print image, contributed to the vi tal heart of dactylogram verification with the mouse. The mouse has been made po ssible by taking account of the roomy space within mouse, tiny chip patch for fi ngerprint identification, together with small size of available microprocessors, The mouse can be used as an normal pointing device while maintaining the capabi lity of user identity distinguishing. The usage of this device is very easy and reliable. The purpose, principle and system design of the mouse are introduced i n this paper. The characteristics and applications of the device are also presen ted.
