It's also not so good for the visually impaired because you can't really provide an audio version of the challenge, whereas identifying the letters in a random string is easier to present as audio.
- togasystems 16y agoDo captcha bots ever use the audio string? Could you not hook up a voice recognizer to the audio portion?

- what 16y agoThat's true. Maybe you could do something with profiles from FB. Show a small collections of faces one of which is your friend on FB. Then you have to select your friend. For the visually impaired you could read peoples' names. A real person would instantly recognize one of their friends and even the guy getting paid to solve captchas would have a hard time. Of course, you then have the problem of getting someone to connect FB to the CAPTCHA service for the first time instead of abandoning the form.
