摘    要:针对网络考试缺乏有效监控措施问题,设计了一种基于虹膜识别的网络考试防作弊系统。此系统采用阈值分割和微积分算子法定位虹膜区域,利用二维Log-Gabor滤波器提取虹膜特征,以及使用汉明码距离匹配虹膜特征来完成身份认证,且采用RSA算法在网络中加密传输。整个系统具有身份认证识别率高和安全可靠性高的特点。经测试,使用效果良好。

关 键 词:网络考试  身份认证  虹膜识别  Log-Gabor  RSA

Abstract:In view of lacking effective monitoring measures, a network examination anti-cheating system was designed based on iris recognition. To complete the personal identification, the system used threshold segmentation and calculus operator method to locate the iris region, 2D Log-Gabor filter to extract the iris feature and Hamming distance to match iris features. And the RSA algorithm was used in the network encrypted transmission. The whole system has a high recognition rate, safety and reliability. It was proved effective in the tests.
Keywords:network examination  personal identification  iris recognition  Log-Gabor  RSA
