摘要
目前基于J2EE平台的信息系统的使用越来越广泛,但是,它在身份认证技术方面还存在一些不足,例如,它易于被自动填表机器人程序利用反复提交表单,从而抢占了网络连接。文中提出了一种基于CAPTCHA的认证模块与身份认证技术JAAS相结合的实现方式,它扩展了一般的身份认证技术的功能,解决了区分真人和计算机的问题,使认证更安全。最后把该技术应用到了实际的项目中,取得了满意的效果。
Ahhough application systems based on J2EE platform is more popular, it is insufficient in ID authentication, such as automatically submiting form by computer prcgrams called Auto- Filling Robot,then net connections are wasted. The article brings forward a method to implement the integrating CAPTCHA with JAAS. We extend the common authentieation＇s function and solve the problem how to tell computers and humans apart by this kind of method that makes authentication more secure, Finally, our project apply the technology,and it works not bad.
