An Efficient Biometric and Password-Based Remote User Authentication using Smart Card for Telecare Medical Information Systems in Multi-Server Environment

摘要: The medical organizations have introduced Telecare Medical Information System (TMIS) to provide a reliable facility by which patient who is unable go doctor in critical or urgent period, can communicate through server via internet from home. An authentication mechanism needed TMIS hide the secret information of both parties, namely and patient. Recent research includes patient's biometric as well password design remote user scheme that enhances security level. In single environment, one responsible for providing services all authorized patients. However, problem arises if wishes access several branch servers, he/she needs register servers individually. 2014, Chuang Chen proposed an multi-server environment. this paper, we shown their scheme, non-register adversary successfully logged-in into system valid To resist weaknesses, environment where patients root telecare called registration center (RC) time get registered smart card. Security analysis comparison shows our provides better with low computational communication cost.
