New Puzzles That Tell Humans From Machines


No, you're not seeing things--that parrot really is upside down.

Have you ever wondered about those squiggly words and letter/number combinations you need to figure out and then type into a box when you register at many online sites lately? They're becoming more and more ubiquitous as many sites and companies now use them to block spam and other illegal postings. They're called captchas, short for “completely automated public Turing test to tell computers and humans apart,”referring to the test proposed by British mathematician Alan Turing to determine if a computer can be said to think like a human.

Here is a short article from today's New York Times describing future possibilities we may see shortly, New Puzzles That Tell Humans From Machines.

The parrot image is one that google researchers are testing that requires people to turn randomly rotated images upright; it can be built around a site's theme. It sounds like we can expect more and more different puzzles in the future.

It is always nice to find a new word. Thank you my dear. I have also never met anyone who actually lived in a salmon.

Oops. Speed reading again.

I used to work with exotic birds. There's only problem I can see with the visual puzzles featuring the birds. Those Toucans, Macaws, and Cockatoos spend most of their time hanging upside down!

As if this old dawg needs something MORE to contend with

Garry, Switzerland, eh? Beautiful. As for living in the salmon, what do you expect from someone who spent 35 years in Oregon? ;-0

Yarntangler, perhaps they spend most of their time upside down, but I'll bet google is hoping most people don't know that. I'll be interested in seeing the types of pictures they choose to use.

Old Newsie, aw c'mon. You already contend with the crinkly words every time you post a comment somewhere on google. I think pictures would be much more interesting. Don;'t know about you, but I sometimes have ar eally hard time trying to figure out the letters.
