Spammers Solving Difficult AI Problems With An Underground X Prize
from the fascinating dept
Slashdot points us to an interview with Luis von Ahn (who we're a big fan of), where he talks about how spammers who are frustrated by various types of CAPTCHA tests have set up their own sort of "innovation prize," offering up somewhere in the range of $500,000 for software that can automatically pass CAPTCHA and reCAPTCHA reading tests (the things where you have to fill in a series of letters to sign up for a service or post a comment). As von Ahn points out: "If [the spammers] are really able to write a programme to read distorted text, great -- they have solved an AI problem." It is, effectively, an "X Prize" for optical character recognition. Not that we like to encourage spammers, but it is rather fascinating how the underground business seems to mirror the above ground innovation world as well.

Awesome
The neat thing is that it forces you to decipher *two* words, one of which is already known and one which is not. If you get the known word right, you pass. Once enough people give the same answer for a particular unknown word, though, that information is passed back upstream to the book digitizers.
If the spammers can solve this reliably, it means that they've made a great advancement in the field of OCR which can be passed back to the book digitizers for great benefits. And it still won't defeat reCAPTCHA unless the new software is *perfect* - there will still be words that can't be read by the new software.
