A biometric authentication scheme for telecare medicine information systems with nonce.
In recent years, the increased availability of lower-cost telecommunications systems and customized patients monitoring devices made it possible to bring the advantages of telemedicine directly into the patient's home. These telecare medicine information systems enable health-care delivery services. These systems are moving towards an environment where automated patient medical records and electronically interconnected telecare facilities are prevalent. Authentication, security, patient's privacy protection and data confidentiality are important for patient or doctor accessing to Electronic Medical Records (EMR). A secure authentication scheme will be required to achieve these goals. Many schemes based on cryptography have been proposed to achieve the goals. However, many schemes are vulnerable to various attacks, and are neither efficient, nor user friendly. Specially, in terms of efficiency, some schemes are resulting in high time cost. In this paper we propose a new authentication scheme that is using the precomputing to avoid the time-consuming exponential computations. Finally, it is shown to be more secure and practical for telecare medicine environments.
