It turns out that while you're proving to the web server you're a human, you might also be pitching in to provide one of Google's services to its corporate customers. A woman filed a class action lawsuit against Google last Thursday in US District Court in Massachusetts, alleging that Google's reCAPTCHA service has harvested unpaid image-to-text transcription work from millions of web site visitors. Google markets reCAPTCHA as a service to web site owners; its customers include Facebook, Twitter, and Ticketmaster. Like other CAPTCHA implementations, reCAPTCHA challenges site visitors to type in the text corresponding to a visually distorted word. But reCAPTCHA differs from the others in that its images often contain two distorted words, as noted by the civil complaint:

One of those words is a “known” word, which the website user must enter correctly to access the website as a security measure. That is, because Google already knows what word is being displayed in the first distorted image, if the user enters the word correctly, Google knows the user is likely to be a human, and thus permits the users to continue using the website...

The other of the two words, however, serves no security purpose. The second word is an image with text that Google is attempting to transcribe. The sole purpose of the second word is to require the user to read and transcribe the word for Google’s commercial use and benefit, with no corresponding benefit to the user.

The lawsuit notes that Google makes use of optical character transcription for its own products such as Google Books and Street View, and also provides an archive digitization service to newspapers, including the New York Times.

This was apparently never a dark secret; the use of reCAPTCHA to "crowdsource" digitization of old printed materials was publicized as a feature by both Luis von Ahn (who invented reCAPTCHA as a graduate student at Carnegie Mellon University) and Google (who acquired the reCAPTCHA technology in 2009):

reCAPTCHA technology was developed not merely with an eye toward improving cyber security, but also as a way to harness and reuse the collective human time and mental energy spent solving and typing CAPTCHAs—a concept von Ahn has dubbed “human computation.” By constructing CAPTCHAs using words tagged as unreadable in the digitizing of books and other printed material, millions and millions of cyber users play a part every day in the digitization and preservation of human knowledge by transcribing words. Tests have shown that reCAPTCHA textual images are deciphered and transcribed with 99.1% accuracy, a rate comparable to the best human professional transcription services.

    When I work for free, I tend to really put myself into my work. If it is food, a bit of spittle is usually enough. And for google, I spit into the captchas, just to have some ownership of the work. Copyright is nothing compared to actual DNA!

      Au contraire, mon ami! That is only if you wipe it off. Right now, I can barely read Google, let alone understand what it means. Maybe there is no reality beyond this, the Google universe, and all those who speak of the "ungooglebar" are only deluded fools, wishing for a transcendent reality that does not exist, and cannot exist because if it could it would be "Googlebar". I believe these terms are Swedish, but I am not sure, only being a small fraction Swede and having none of the language. Hummmm,, Google translate! See? I told you! Felix Navigation!

    See, this is why people want labels on food containing DNA []! ;)
