The characters are part of a 4 character saying - but rearranged in a different order. You are supposed to take the characters and put them in the correct order. For your original image, it is 不约而同.

P.S. You can attach images inline if you go to the "more reply options".

For your new image it should probably be 天清气朗, however Google tells me 天朗气清 is also an acceptable combination. Not sure how the captcha system handles it when there is potentially more than one acceptable answer.

Is it just me, or does this new capcha scheme seem INCREDIBLY easy to break by a computer? With a 4 character phrase, there are only 24 possible arrangements. Send all 24 to google, pick the one with the most number of hits. I got to believe this would have a, what, 95%+ success rate?

How many is too many? How long a time? How long do capchas last?

You can also send to different search engines. Wonder if www.google.com talks to www.google.co.uk about this. Could also ask baidu. [Would need to send at least one same sequence to both to allow calibration.]

Just seems too easy.

Capcha is supposed to work by posing a problem that's too hard to solve by computer, like recognizing bad handwriting, or words on a noise background. These characters are much more legible than the usual Capcha. Unscrambling a few characters is not a Capcha. That's easily done by matching against a dictionary.

Actually, this is a fairly typical capcha and is indeed a capcha. The goal of a capcha is to prevent automation and this falls within that realm as if you autmated what's going on here, it would be much more than a few lines of code. Doing math like "3+2" or using words like what's "three minus two" are all forms of capcha and this is another form as well. Unscrambling english is something common too. Never seen chinese since I don't go on as many of those websites, but it seems to be a variation of unscrambling english.
