【Abstract】 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.更多还原
