In virtue of advances in smart networks and the cloud computing paradigm, smart healthcare is transforming. However, there are still challenges, such as storing sensitive data in untrusted and controlled infrastructure and ensuring the secure transmission of medical data, etc. The rapid development of watermarking provides opportunities for smart healthcare. In this paper, we propose a new data-sharing framework and a data access control mechanism. The applications are submitted by the doctors, and the data is processed in the medical data center of the hospital, stored in semi-trusted servers to support the selective sharing of electronic medical records (EMR) from different medical institutions between different doctors. Our approach ensures that privacy concerns are taken into account when processing requests for access to patientsí medical information. For accountability, after data is modified or leaked, both patients and doctors must add digital watermarks associated with their identifications (I.D.s) when uploading data. Extensive analytical and experimental results are presented which show the security and efficiency of our proposed scheme.
