M-Healthcare Cloud Computing System for Multilevel and Single Handled Privacy Preserving Cooperative Authentication in Patient Diagnosis

A patient attribute-based designated verifier signature a patient self controllable multi-level privacy-preserving cooperative authentication security and privacy requirement in distributed m-healthcare cloud computing system. Distributed m-healthcare cloud computing system significantly sencourages productive patient treatment for therapeutic discussion by sharing individual wellbeing data among human services suppliers. Nonetheless, it brings regarding the challenge of keeping each the information confidentiality and patients’ identity privacy at the same time. Numerous current get to control and unknown validation plans can't be clearly abused. To take care of the issue, in this paper, a novel approved open protection Model (AAPM) is set up. Patients can authorize physicians by setting an access tree supporting flexible threshold predicates. At that point, in light of it, by formulating another method of characteristic based assigned verifier signature, a patient self-controllable multi-level privacy-preserving cooperative validation scheme (PSMPV) realizing three levels of security and privacy requirement in distributed m-healthcare cloud computing system is proposed. The directly approved physicians, the indirectly approved physicians and the unauthorized persons in medical consultation can restorative decipher the personal health information and/or verify patients' identities by satisfying the access tree with their own attribute sets. Privacy in the distributed m-healthcare cloud the formal security evidence and simulation results illustrate our scheme can resist various kinds of attacks and far outperforms the past ones as far as computational, communication and capacity overhead.
