Poster: BlinkSecure: Risk-aware Continuous Authentication using Blink-based CAPTCHA and Face Recognition

Text-based password credentials have evolved into biometric authentication, specifically facial recognition. CAPTCHAs have been widely used to prevent automated bots and(or) unintended actors from performing malicious actions. CAPTCHAs have also evolved from the transcription of random distorted text from an image to behavior-based CAPTCHAs. In this paper, we propose a research prototype titled BlinkSecure, which provides a risk model aware combination of authentication and bot detection that uses the same biometric face where face recognition authentication is coupled with the eye blink-based CAPTCHA. It can be used in a wide range of applications such as eLearning and also beneficial for accessibility.
