Better way of fighting spam register bots
By pavic | November 11, 2006
Working on budgetzen app, and chatting with ingenious Brian Breslin from Infinimedia, I’ve felt on my mind an new idea how to fight spam register bots, since some of them can recognize captcha images.
Let them recognize em, was my idea, but let there be 2 antispam images, and input box, that requires sum of those 2 numbers.
No spam bot yet sums the numbers.
So here is it in action: www.budgetzen.com
For initial purpose I used jpgraph, but any set of images can be used trough ordinary php or gdlib.
