| 摘 要： | 随着越来越多的“网络机器人”在Intemet上活动，网站的安全性问题显得越来越严峻。全自动人机识别系统（CAPTCHA），一个让人类能够通过测试，而当前的计算机不能通过的程序出现了。它的原理建立在未解决的人工智能问题领域。通过对几种在实际安全应用中的不同CAPTCHA结构的考察，描述了它们的原理、模型和优缺点，并结合我国情况，提出了基于中文文字识别的CAPTCHA模型，详细描述了在中文CAPTCHA编程设计中的实现策略。

| Abstract: | With more and more web "bots" crawling on internet like a human,security of web sites are more serious than before.CAP-TCHA,an automated test that humans can pass,but current computer programs can't pass: Any program that has high success over a CAPTCHA was used to solve an unsolved artificial intelligence(AI) problem.Since CAPTCHAs have many applications in practical security,several novel constructionsofCAPTCHAs are introduced.And,theirprinciple,practicing model,advantage and disadvantage are described.Herewith the security of Chinese websites,based on Chinese character identification CAPTCHA model is constructed.Detail policy in programming and realizing Chinese CAPTCHA is introduced. |
