AndyB Posted April 5, 2007 Share Posted April 5, 2007 Readable by every human and unreadable by every shape recognition bot, right? Let's think about that for a moment ...

per1os Posted April 5, 2007 Share Posted April 5, 2007 The best way is to create a sentence IE: What is the maximum number out of 10, 14, 23 and 22? And have that displayed in the image. This way the bot does not know what it is looking for and a user can easily read it and write "23" in the textbox. It is best to have it random so the next question might be: Who invented the light bulb, Edison, Jordan or Shaq? That is the best right now until someone figures out how to crack that.

mattd8752 Posted April 6, 2007 Share Posted April 6, 2007 As a response to the last post, be careful with the questions. I had a script like that, I asked how many colors are in the Canadian flag and most people answered 3 because there are 3 different stripes... Log the results to questions so that you can check the answer. Or even What color is in the *shape name* and have multiple shapes one with that color as the fill then a few choices. Questions are actually getting better than CAPTCHA, more like CAPTCHA is being beaten, but you should get my drift.
