[PHP] Ticketmaster.com and Word Images
Does anyone know how sites like Ticketmaster.com creates the Word Image used for ticket purchase verification? Do they generate the image on-the-fly from a dictionary, or do the images pre-exist and they are pulled from a DB along with the word.

The simplest is to generate the image yourself, and you can use a pseudo-caching method to pull them statically if they are not already generated. This method can still be automated, but it is at least more difficult than writing a simple script, as it requires some OCR. If you want to go the extra mile, check out this site: http://www.captcha.net/ gimpy-r is what Yahoo! uses for their registration. These images are extremely difficult to reliably read with a computer program, so they offer much stronger protection against automated attacks. If you specifically want to know what TicketMaster/CitySearch uses, you should ask on the mod_perl mailing list, because a few of those guys work there. Hope that helps.
