Abstract: 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 are inefficient in distributed m-healthcare systems. To solve the problem, in this paper we have established a novel authorized accessible privacy model using AES (Advanced Encryption Standards) and Homomorphic algorithms to provide multi-level privacy-preserving cooperative authentication scheme. Distributed m-healthcare realizing three levels of security and privacy requirement and patients can authorize physicians by setting an access tree supporting flexible threshold predicates.
