Abstract

Captcha is a security mechanism designed to differentiate between computers and humans, and is used to defend against malicious bot programs. Text-based Captchas are the most widely deployed differentiation mechanism, and almost all text-based Captchas are single-layered. Numerous successful attacks on the single-layer text-based Captchas deployed by Google, Yahoo! and Amazon have been reported. In 2015, Microsoft deployed a new two-layer Captcha scheme. This appears to be the first application of two-layer Captchas. In this paper, we examine the security of the two-layer Captcha. We attack this scheme by a series of processing.
