| Abstract: | The verification code technology is used to produce an image made up of random mathematical number of signs, so as to prevent the net users from using robots to automatically register, logon and paste junk info. This technology is difficult to be applied, and thus an image technology based on PHP verification code is inteoduced,which proves easy and efficient. |
