一种基于汉字笔画的验证码生成技术

A verification code generation technique based on strokes of chinese characters

文章提出一种基于汉字笔画的验证码生成技术.该验证码生成技术利用GIF动态验证码的优点,采用笔画、汉字以及GIF动画提示,要求验证者在给出笔画中按顺序选出汉字的正确笔画,并从给出的汉字中选中正确的汉字,利用DES加密算法实现B/S通信的传输安全,有效防止OCR识别技术,提高验证码安全性,增强了用户的体验感.

This paper proposes a verification code generation technique based on the strokes of Chinese char-acters, the verification code generation technique using the advantages of GIF dynamic verification code, considering strokes, Chinese characters and GIF animation tips, and the users were asked to select the cor-rect Chinese character strokes and the correct Chinese characters from which were given, and the DES en-cryption algorithm was used to ensure B/S communication transmission security. Therefore the verification code generation technique can efficiently prevent the OCR recognition technique, improve the security of ver-ification code, and enhance the user, s experience feeling.
