一种彩色图形验证码在WEB开发中的应用研究

摘要

在开发 WEB网站或应用系统程序时，为了防止一些黑客盗取或恶意破解密码、刷票、论坛灌水、刷页以及对某一个特定注册用户用特定程序暴力破解方式进行不断地登陆尝试等操作，需要在登录页面中加入附件验证码程序，而运用彩色图形验证码生成技术，编写相关程序，可更好地达到保护的目的。%In the development of WEB site or application programs, an attachment program verification code on the login page is needed no only to prevent some malicious hackers from stealing, cracking passwords, brushing votes, spamming, brush pages and other similar operations, but also to effectively prevent hackers from constantly trying to login in a particular registered user's account by a specific program. In this paper, color graphics authentication code generation techniques, preparation of related programs and its application to the WEB development is studied.
