The Internet of Things (IoT) and cloud technologies have significantly facilitated healthcare. In such a context, medical data are collected by the terminals from patients, manipulated, stored on hospitals (doctors). This brings asymmetry problems in access control, processing, storage between doctors which results sharing face many challenges as privacy leakage malicious feedback servers queries. To solve these problems, this paper proposes scheme with cloud-chain cooperation policy fusion...
In medical data sharing, the access control authorities of sharing entities and computing capabilities platforms are asymmetric. This asymmetry leads to poor patient over their data, privacy disclosure, difficulties in tracking sharing. aarticle proposes a cooperation model cloud chain (CMCC) for secure data. CMCC, power equivalence blockchain nodes limits authority between doctors patients Moreover, server is used store some node-side computations handed cloud, which addresses asymmetric...
