Audio CAPTCHAs Cracked; ReCAPTCHA Remains Strong

Posted by ryuzaki0 on from the captcha-captcha-chameleon dept.

Falkkin writes "Ars Technica reports that audio CAPTCHAs consisting of only distorted digits or letters can be easy to crack using machine learning techniques. This includes most of the audio CAPTCHAs currently in use on the Web. The reCAPTCHA team has discussed their new audio CAPTCHA, which is resistant to this attack."

    They should just make a CAPTCHA that requires strong AI to crack; we could make a great leap ahead in AI by letting the spammers solve all the problems for us!

    In my crystal ball I see some fool who does not turn off the sound on the PC in an office.

    By law, offices of companies over a certain size must accommodate people whose disability requires sound to do their jobs.

    Unfortunately, history has shown that many people also still have digital camera's that make the *click* noise

    By law, camera phones must make the click noise when operated within some countries to help fight voyeurism.
