Of course the principle drawback with captcha codes is that they are designed to be somewhat tough to read (you might be surprised how many on the market can now be “read” by a computer program). This could be a downside, especially for the visually impaired. One answer is to offer an audio model of the captcha code.
CAPTCHA is weak to a relay attack that uses humans to resolve the puzzles. One approach entails relaying the puzzles to a group of human operators who can solve CAPTCHAs. In this scheme, a computer fills out a kind and when it reaches a CAPTCHA, it offers the CAPTCHA to the human operator to solve.
