Eye Tracking Solutions in Cognitive CAPTCHA Authentication

Abstract

This paper will describe new areas of eye tracking application connected with secure user authentication, using cognitive CAPTCHA codes. Cognitive CAPTCHA require special knowledge or perception skills, during selection of visual parts for personal authentication. In such protocols can be also implemented contactless interfaces in the form of eye tracking devices. Application of such technology allow to trace the point of attention which should be focused on proper visual elements in proper semantic order for successful user authentication.
