That could generate a lot of OCR corrections, while disguised as a "normal" part of daily Internet life.Ballardhttps://www.blogger.com/profile/01319346878358165365noreply@blogger.comtag:blogger.com,1999:blog-6569681.post-4108643972010118552007-05-30T00:52:00.000-07:002007-05-30T00:52:00.000-07:00There are two notable sites that works on cracking...There are two notable sites that works on cracking captchas, http://sam.zoy.org/pwntcha/ and http://www.ocr-research.org.ua/list.html<BR/><BR/>Both of their guidelines may deduce that reCaptcha's technology isn't anything new.<BR/><BR/>Funnily enough, am working on a captcha, soon to be released. Following strictly on the guidelines that those websites have given, I think I might have beat it, for now. ;)KwangErn Liewhttps://www.blogger.com/profile/13959942175376408140noreply@blogger.comtag:blogger.com,1999:blog-6569681.post-74223660705130789692007-05-29T15:18:00.000-07:002007-05-29T15:18:00.000-07:00Luis Von Ahn's work is indeed very clever.However,...Luis Von Ahn's work is indeed very clever.<BR/><BR/>However, his human computation games actually lie to players though this doesn't seem to bother many people. The deception is clever after all.<BR/><BR/>In particular, when playing a two-player game, there is a clear expectation that you will be playing with another human live. But this is not always the case. See for example see the sections on pre-recorded gameplay and cheating here:<BR/><BR/><A HREF="http://www.cs.cmu.edu/~biglou/ESP.pdf#page=3" REL="nofollow">http://www.cs.cmu.edu/~biglou/ESP.pdf#page=3</A><BR/><BR/>As for reCaptchas you may be getting free labor out of users without their permission. And even if users were to be informed of what is going on, I would expect that many of them would not really understand it. But you will be getting free labor out of them anyway.Anonymousnoreply@blogger.com
