Renewable and Anonymous Biometrics-Based Remote User Authentication Scheme Using Smart Cards for Telecare Medicine Information System

A rise of prevalence ageing population and chronic diseases in Saudi Arabia, patients need to be regular face-to-face meet Doctors/physicians for consultation and treatment. Telecare Medical Information System (TMIS) enables patients to gain remote access their medical information and medical services. Patient authentication and privacy-preserving have become more challenging. Recently, some biometric based remote user authentication schemes using smart cards for TMIS have been proposed. The schemes are not secure against the tampering and theft by way of a stored biometric template, privilege insider attack, and stolen/lost the smart card. Furthermore, these schemes have computation and communication costs overruns. This paper presents an improved efficient and secure biometric remote user authentication scheme with renewability and anonymity has been proposed to remedy the weakness of these schemes. The security analysis and performance comparison of the proposed scheme is formally given and showed the advantages over these schemes.
