New idea for CAPTCHA?

[lupus6x9]

I thought of this last night. I haven't seen anything like it, so maybe it's my original idea? (Don't have those often! :D)

I have seen CAPTCHA's that simply make you type the words in the image into the box, and I have seen ones that make you solve a math problem. But I haven't seen any yet that simply ask you generic knowledge questions, and so I think that this might be more difficult for a computer to crack. After all, computers can be programmed to try to "read" the phrase, regardless of the background, and they are designed, after all, to perform mathematical operations, but I think my idea might be better.

For example:

What fruit is named after the color of its peel? orange
What comes next in the pattern? One, ten, two, nine, three, _____. eight, 8
What is a very common four-legged household pet (three letters)? dog, cat, rat
What is the common name for floating white blobs in the sky? cloud
What color are the spots on a white cow? black
What animal makes the "oink" sound (three letters)? pig

Of course, it would check case-insensitively and be lenient enough to allow for punctuation in the answer as well as having a plural answer.

Yep, approaches like these make it very fun for the user. I've done a few of these before on some phpBB forums. :)
For example, I discovered http://justhumans.com/ about 2 weeks ago. Its very fun unlike a regular CAPTCHA which might just be annoying to some.

And a rat is a common household pet? :P

It was three letters. What if someone didn't think of "cat" or "dog"?! :D

Here's another one:

How many letters are in the answer to the question, "How many letters are in the word 'two?'" (just to really confuse them; the answer is five [5], obviously)

The problem with this type of captcha is that people are stupid. :)

Jay Leno went around asking people who the Vice President of the United States is (**** Cheney, btw) and almost no one knew. See. ;)

Actually, I considered adding a question, "Who was the first president of the United States?" but, seeing as not all users may be American, that could be a pain. But who DOESN'T know what color a white cow's spots are?!

Yeah, that would be very annoying. Someone who hasn't seen a cow before. :P (Lol, sorry)
I have a stupid idea, but how about adding "type this word backwords or in all case LOL."

Ok it took me ages to work out how there are 5!

That's a good idea, actually. And it's probably easier for most people, since there's no "trivia" involved (you know, since knowing the colors of a cow are TRIVIAL). :D

Yeash and what if you live in a country where there are no cows? And cows can also be just brown! (Edit: I see now, its white cows spots)
