摘要:
针对因特网安全防范中验证码的普遍使用,讨论了验证码的功能原理、常用的识别方法,选取了部分网站干扰不同的验证码进行了分割、识别实验.结果表明:互联网上有相当多的验证码不能有效地保证系统的安全.提出一种验证码的改进方法,该方法程序简单,产生的新验证码可以提高识别难度和降低破解的准确率,具有一定的推广价值.最后给出了验证码设计的建议.
Abstract:
In a llusion to thew ide use of identify ing codes in internet security and identification authentication, the paper d iscusses the func tiona l pr inc iples o f identify ing codes and commonly used w ay s o f recognizing identify ing codes. Seg m enta tion and recogn ition exper im ents of identify ing codes arem ade. The experim ental results ind icated tha t the ex isting identify ing codes are no t effective in ensu ring the system security. An improved m ethod is propo sed in th is paper. Its prog ram is sim ple and effec tive, and the new ly gene rated identify ing codes can increase the d ifficulty o f recogn ition and decrease the accuracy o f dec ipherm ent. Thus, it has a good value of prom otion. Som e suggestions on identifying code design ing are g iven in the end of th is paper.
