Towards mobile cloud authentication and gait based security using time warping technique

Abstract

In this paper, we propose an effective algorithm called multi-cross template matching using fast dynamic time warping (MuCFdTW) and is used in authentication and data security through gait based encryption, in mobile cloud services. MuCFdTW improves the authentication of the user in lesser time with an accuracy of more than 99%. The data flow between the mobile device and cloud server is secured through encryption using Organization ID and private key. These keys are derived from the parameters of Gait cyclic patterns, which enhances the security by double fold. This framework effectively addresses the efficiency limitations of public key generation and computational overhead. It also removes the revocation issues as the access of the users will be automatically revoked as they move out of the organization sites. Experimental results and comparison reveals that false positive rate is better compared to other existing identity based systems with encryption and decryption time ranging from 3 to 5 ms and the time taken is comparatively less ranging from 3.4 $${\pm }$$ 0.5%.
