Software request

I was posting a couple of comments on Kaiser’s blog, and I’m finding the CAPTCHA’s there increasingly hard to read. I was thinking that some good software would be helpful.

Is there a browser attachment I could download that would automatically read CAPTCHA’s and translate them into letters and numbers? This would be very helpful. I’d appreciate any tips in this direction.

  1. Wouldn't it defeat the purpose of CAPTCHA if such software existed? In fact, I'm pretty sure this is why they are getting harder to read – to outpace the ability of software to interpret the letters and numbers.

    Or maybe this post is some sort of subtle joke…

  2. If such a thing existed, CAPTCHAs would be completely pointless. Spammers would use it to post spam comments, automatically create millions of accounts with free email services, etc. Indeed, the process of developing such a tool is called "breaking" a CAPTCHA, analogously to breaking a lock. I'm sure that some CAPTCHAs have been broken, but I do not know the details.

  3. Well sometimes you can cheat on ReCaptcha (the one which shows you two words), only one word is known. Thus you can write the easier one among the two and any random letters for the other one, this guarantees 50% chance of passing the captcha.

  4. Plowshare actually uses standard OCR libraries quite successfully for the captchas on Megaupload and the like. Captchas aren't as hard as they might seem, for many sites.
