A CAPTCHA in the Rye


How effective are CAPTCHAs as a security mechanism against malicious automation? We report and analyze four case studies and draw conclusions as to the best ways to implement CAPTCHAs as an integrated part of a security strategy. Specifically, security teams should use novel CAPTCHA methods that make the CAPTCHA into something enjoyable, like a mini-game. Also, we help identify how to present a CAPTCHA only when users exhibit suspicious behavior by implementing various automation detection mechanisms.
