网上考试系统中指纹验证模块的研究与算法实现

网上考试中运用指纹认证方法,可以有效地杜绝代考现象的发生.文中探讨了网上指纹验证过程中的算法实现,综合运用图像处理和模式识别技术,研究了指纹识别的理论和技术,建立了一对一的指纹识别系统.整个系统框架采用浏览器/服务器(B/S)结构,用户在客户端提交指纹图像,而服务器端则完成指纹图像的预处理、匹配算法等,再将识别信息反馈给客户端.

Research on Algorithm Realization of Fingerprint Verification Module in Internet Exam System

Along with the rapid development and popularization of Internet in the world, the technology of on line exam rapid development. Using the method of fingerprint verification in the on-line exam system, one may effectively prevent the substitution as for exam. In view that biology recognition technology can realize authentic identification, more and more on-line exam systems work with fingerprint verification. The paper describes the algorithm realization of fingerprint verification module in Internet exam system. Using technology of image processing and pattern recognition, we investigate the theory and methods of fingerprint identification. The whole system uses the structure of B/S. The user puts forward the finger at the browser and the image preprocess and recognition are all done by the server. After the recognition information is processed by server, it is send back to the browser.
