Will Microsoft's CAPTCHA project Assira be ready for prime time by Dec '09?
Background: Security researchers say that spammers have found ways of circumventing the CAPTCHA test protocols used to protect free email services, and that new approaches are needed to prevent spammers from abusing these systems. Spammers have developed several techniques to defeat CAPTCHAs, including using mechanical turks, people who either directly or indirectly create accounts traded online. Other spammers use software to crack CAPTCHAs, which is what CAPTCHA security researchers have focused on preventing. Microsoft is working to enhance its CAPTCHA system to make it both more readable for people and less vulnerable to automated attacks. Some improvements include new image distortion logic, overlapping characters, and dynamic monitoring to observe attacks in real time to make quick adjustments. One Microsoft CAPTCHA project, dubbed Asirra, asks users to identify 12 photographs as either cats or dogs. Another project, called Inkblot Authentication, asks users to form semantic associations with a set of randomly generated inkblot-like images, which are used to authenticate the user. Asirra is already in use as a prototype at several organizations. Microsoft researcher John Douceur says the challenge in designing a CAPTCHA is creating a way of generating several unique instances of the test and making it possible for the system to easily determine whether the user answered the CAPTCHA correctly
