One way to make OCR ineffective against them is to use pictures of something, instead of strings. For example, show photos of well-known people, buildings, or animal species and ask the person to type the name. For a bot to beat that, it would have to do sophisticated pattern-matching against a large library of pictures, making it infeasible for spammers.

Unexpected benefit? Posted Aug 24, 2006 16:13 UTC (Thu) by NAR (subscriber, #1313) [Link] I'm afraid it would be really hard to create a set of images that every user would recognize - after all, "well known" is a relative concept.
