I. Introduction
Due to the various market (consumer, product, service) entering into the social media, reliable and secure communication between the users are one of the most important problems to be addressed. In recent years, both single and multimodal biometrics user authentication have been explored extensively in addressing this challenge. A collaborative Face Recognition [1] with the aid of social graph addressed the problems related to hit rate, ensuring authentication rate. Game theoretic models were presented in [2] [3] using fingerprinting to minimize the collision rate. At the same time, a multimodal biometric system was proposed in [4] [5] using behavioral traits to measure the presence of students in virtual classroom. An additional factor of gestures for different face characteristics was presented in [6]. Identity authentication was on the other hand ensured in [7] through keystrokes.
