This paper proposed a cloud-assisted mobile-access of health data with privacy and audit-ability. The system consists of two components: searchable encryption and auditable access control. Upon receiving the health data from users, the private cloud processes and stores it on public cloud such that storage privacy and efficient retrieval can be guaranteed. The private cloud engages in the bootstrapping of data access and audit-ability scheme with users so that it can later act on the users’ behalf to exercise access control and auditing on authorized parties. The System provides storage privacy requirements Data confidentiality, Anonymity, Unlink-ability, Keyword privacy, Search pattern privacy. In emergency data access, the users may be physically unable to grant data access or without the perfect knowledge to decide if the data requester is a legitimate EMT (Emergency medical technician). Require authorization to be fine-grained and authorized parties’ access activities to leave a cryptographic evidence.
