Two factor remote authentication in healthcare

In order to control access of health related data stored in public cloud, efficient authentication mechanism needs to be considered. Biometrics authentication is more reliable than traditional means of authentication because of its uniqueness and low intrusiveness. To ensure high accuracy level, two factor authentication mechanism is proposed here. In this framework, biometrics authentication is fused with secret PIN. The first factor uses simple and effective behavioral biometrics keystroke analysis model whilst the second factor uses secret PIN mechanism. In factor one authentication, keystroke analysis is proposed where raw data are collected first; then processed data are stored and trust scores are generated finally. End-user gets trust score at each factor of authentication and decision is taken based on final trust score of end-user. Performance analysis of the proposed mechanism shows its efficiency to authenticate end-users.
