A novel PSMPA technique for m-healthcare cloud computing systems

Abstract

In m-healthcare cloud computing systems, the personal health data often distributed among the patients located in particular social networks suffering from the similar disease for shared support, as well as across distributed healthcare providers (HPs) prepared with their own cloud servers for medical consultant. However, it brings regarding the challenge of keeping each the information confidentiality and patients’ identity privacy at the same time. Several existing access management as well as anonymous authentication schemes cannot easily exploited. For that in this project, we propose an authorized accessible privacy model (AAPM). Then, based on it, by devising a new technique of attribute-based designated verifier signature (DVS), a patient self controllable multi-level privacy-preserving cooperative authentication design (PSMPA) realizing three levels of security as well as privacy requirement in distributed m-healthcare cloud computing system is proposed.
