We propose IMAGINATION (IMAge Generation for INternet AuthenticaTION), a system for the generation of attack-resistant, user-friendly, image-based CAPTCHAs. In our system, we prod...
In this paper, we present a bio-inspired unified model to improve the recognition accuracy of character recognition problems for CAPTCHA (Completely Automated Public Turing Test t...
Efforts to defend against automated attacks on e-commerce services have led to a new security protocol known as a CAPTCHA, a challenge designed to exploit gaps in the perceptual a...
