Audio CAPTCHAs Cracked; ReCAPTCHA Remains Strong

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."

I'm half afraid to admit this publicly, but did anyone else try clicking the "play" button on screenshot of the audio CAPTCHA player in the first article? I took me a few tries before I realized it was only an image.

Solution to AI research?

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!

trust me, his mom would be down for that. in fact, she handles multiple requests simultaneously. in the true multiple cores way, not the hyperthreading way

Audio requred by law

[tepples]

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.

I'm trying to figure out what that translates to, but it's making my head hurt. So hyperthreading means she is "emulating" multiple "interfaces" with just one... Ow.

BTW, CAPTHCA for this post? "Receptor".

Don't know what your problem is- I'm a perl script and I understood it just fine.
