Comment Re:Scope of site content vs. scope of CAPTCHA cont (Score 1) 267
my point was simple questions that require simple, one word, case insensitive answers. regardless of the type of site one is visiting. the color of blood (three letter word), what is a three letter word for frozen water, what do chickens lay that has a yolk...
and if, in turkish, the word ice has seven letters, then the question, which would be in turkish when on a turkish site, would reflect that.
the point isnt to check for capitals or proper use of apostrophes. the point is that unless a bot is built to recognize specific questions and have a matching answer, it shouldnt be able to enter a correct response. multiple choice questions might be easier but a bot can be built to guess an answer.
an issue that i believe would make textual captcha useless is if the questions are presented too simply, such as the ones above, you could probably build a bot that passes the question to a search engine and tries to determine which word is the answer based on the first page of the results. so maybe it would work better in the form of:
blood is: [input box]
hint: color, 3 letters
again, this is a harder system to develop than the current because it requires a lot of creativity while maintaining simplicity and you dont have the option of random generation. but if done correctly, its easier for humans yet just as difficult (if not more) to decipher programmatically.
