Description

Distributed m-healthcare systems support for efficient patient treatment of high quality, but it brings about series of challenges in personal health information confidentiality and patient’s identity privacy. Many existing data access control and anonymous authentication schemes inefficient in distributed m- healthcare systems. M-healthcare mobile social network has emerged as a promising next-generation healthcare system increasingly adopted by the US and European governments, with the rapid development of sensor and wireless communication technologies. Due to the high cost of building and maintaining data centers, third-party service providers provide healthcare service. But while using third party service providers there are many security and privacy risks in the system. In distributed m-healthcare cloud computing system, only the authorized physicians or institutions that can recover the patient’s personal information during data sharing. In this project, the system proposed a patient self-controllable multi-level privacy-preserving cooperative authentication scheme (PSMPA) realizing three levels of security and privacy requirement in distributed m-healthcare cloud computing system.
