COTCHA is an acronym for Coded Objective to Tell Computers and Humans Apart.
Edit By BS Editor: Have a web form that spammers are using for their own Devious purposes? Many times these forms are actually used by Robots-- programs which surf the Internet and submit junk into web forms everywhere. The problem for these robots is that theyre not very SMART. Usually any sort of challenge which would be obvious to a human will completely confound a program. My COTCHA script is one of these challenges. It generates a numeric sequence and displays it right in your form -- even a form that you have had made for you, or one that youve downloaded from the Internet. When the user or robot submits the form, my script checks to see if this numeric code has been typed correctly. If not, the process is interrupted. Right now the COTCHA number is plain text茂驴陆 the next step of this script茂驴陆s development is to Create an image of the 茂驴陆Cotcha茂驴陆 code using ImageMagick. Since most web servers don茂驴陆t come with the ImageMagick program preinstalled, I茂驴陆m going to leave it off until it茂驴陆s absolutely critical or someone makes a special request for the code to be imagefied. So if you茂驴陆re having trouble with comment spam, feel free to get this script.
