摘要 验证码技术现已成为提高网站安全的一个手段,但是由于只有简单的形变处理,当前很多应用的验证码缺乏可靠的安全性,具有很高的破解率。因此,设计了一种具有字符拥挤效果的、拥有多种变形特征的随机汉字验证码生成算法,并将其成功应用于JSP动态网页中。实验表明,产生的验证码具有更高的安全性,且易于用户使用。 CAPTCHA is a means to improve Web security nowadays.Since only a simple transfigure processing,the most of CAPTCHAs are lack of security and have a high rate to be cracked.Hence the paper designed some new methods of generating random Chinese CAPTCHAs which had crowd effect and multi-transfigure feature,and applied it in JSP dynamic Web successfully.Experiments show the CAPTCHAs generated by the paper are more secure and easy to use.
