基于3D的CAPTCHA验证码研究

Research on the security code based on 3D-CAPTCHA

使用验证码的主要目的是保证网络的用户是真实的用户而非机器自动产生的用户,这有利于保证网站的安全,而CAPTCHA技术主要用于验证码的生成,传统的验证码生成采用的是2D-CAPTCHA技术,目前该技术已经比较成熟,因此,针对此技术的攻击的研究也比较多,导致了该技术使用的不安全性系数增加.针对这一问题,文章研究了CAPTCHA技术的发展新动向3D-CAPTCHA技术.

The security code is used to validate whether the user of a web site user is a real person or a machine automatic user,which can be used to ensure the security of the web sites.The main technology of the security code madding is CAPTCHA.The conventional technology of the security code madding is based on 2D-CAPTCHA,and lots of people study this technology,so lots of the attack technology of 2D-CAPTCHA has been studied,which made the web sites not secure too.In terms of this problem,this paper made a research on the new CAPTCHA technology——3D-CAPTCHA technology.
