Secure data transfer from data owners to the cloud servers, secure data storage and patient data privacy with authorized access control and fine-grained policies.
As mobile computing collects large amount of data from cloud integrated body senor network, it is a challenging issue to keep data privacy and security.
The fusion of health data and social data may pose series of privacy and security issues in smart cities.

Limitation
Total computational cost is proportional to the number of privileges and storage space is proportional to the number of DRs. Need to improve scalability.
No validation for real access of PPPs available.
Storage cost is not evaluated.
Real PPPs and access scenarios are not evaluated for performance measurements.
