Research On The Data Security And Privacy Protection Of The Stroke Medical Association Cloud Platform

With the rapid development of cloud computing and the reform of medical system, the health care industry information sharing is also developing. The stroke medical association information sharing platform based on the cloud computing as part of the medical information, and cerebral apoplexy use cloud computing technology to build information sharing platform,to realize the medical information sharing between hospitals at all levels within the couplet body and interaction.However,there are some potential safety hazard,the traditional Chinese medicine of couplet cloud platform, with the increasing number of users, the security problem will expose more and more privacy. Inside the management o of platform user account,identity authentication and user access and sharing of data transmission, it’s in need of a set of practical and effective solution to ensure the data security and privacy protection in cloud platform.The data security and privacy protection of the stroke medical association cloud platform as the research object.Firstly, according to the characteristics of data resources in cloud computing and conjoined. Analysis of cloud computing security threats faced by the medical system under the environment, and stroke medical association cloud platform demand in terms of data security and privacy protection; Secondly, according to the requirements within the platform proposed identity authentication, access control, and user behavior tracking and the three layers of protection system of the audit; On the outside of the platform using the physical isolation technology, the VPN network and PKI technology related to ensure the safety of the user access and data transmission security. Finally, in view of the user’s privacy, and puts forward a kind of medical couplet of cloud platform oriented user access control model, this model introduced user behavior trust level and the concept of personalized authorization, RB AC role in the activation and the trust of the user behavior value combination, and gives the calculation method of trust level, and realize the dynamic authorization of the cloud computing environment; On the basis of the RBAC model to add personalized authorization policy, implement the fine-grained access control of medical resources.In this paper, on the basis of existing research put forward a set of cloud data security and privacy protection scheme, on the whole protection of data security in cloud platform cerebral apoplexy. And the scheme of access control model is optimized, and through theory analysis and experiment show that the model on the safety, technology and economy has a larger advantage., and proposes the valuable advice for the stroke medical association cloud platform data security and privacy protection, put forward valuable opinion, also for other diseases of the expansion of couplet of medical mode and medical couplet body provide certain reference data security.
