With spammers having already written software to match humans at solving some CAPTCHAs, many are predicting the end of the CAPTCHA. Not so, says Luis von AhnÂ (developer of the reCAPTCHA system) in a New Scientist article that asks why not set the spammers further AI tasks that they can solveÂ inadvertently.
Software that can solve any text-based CAPTCHA will be as much a milestone for artificial intelligence as it will be a problem for online security. [â€¦]
“If [the spammers] are really able to write a programme to read distorted text, great â€“ they have solved an AI problem,” says von Ahn. The criminal underworld has created a kind ofÂ X prizeÂ for OCR.
That bonus for artificial intelligence will come at no more than a short-term cost for security groups. They can simply switch for an alternative CAPTCHA system â€“ based on images, for example â€“ presenting the eager spamming community with a new AI problem to crack.
