碩士 === 國立臺中科技大學 === 資訊管理系碩士班 === 103 === The technology developing quite fast nowadays, each medical institutions have proprietary information systems, the recorded information of the diagnostic treatment stored in a medical information system. However, medical resources only deposited in each medical institutions of medical information systems, if the patient needs to apply for medical resource records, subject to cumbersome procedures and time and from medical facilities. When conflict occurs, such as the user simultaneously grab beds equipment, testing equipment occurred resources used. Taiwan&;apos;&;apos;s large-scale special event recently occurred, resulting in a considerable number of patients with severe acute, but not effective configuration severe acute beds, so patients miss golden rescue time or spend a lot of time waiting for beds. With cloud computing technology is gradually being taken seriously, how effective configuration and management of medical resources to meet the users (patients, medical institutions staff) needs and to maintain security, to become a research topic worth exploring. This study investigated the medical information systems allocate and share medical resources through cloud computing. By application of multi-tenant (Multi-tenancy) The environment provides users to share the same platform in a multi-user environment, according to the needs of users to develop customized lease demand, and ensure that resources between user isolation, quarantine management and Customized mechanism. Looting occurred simultaneous users or user roles by resource conflicts,by using Dynamic Separation of Duty (DSOD),the concept of a user can only play a role at the same time. Apply Role-based access control (RBAC), access rights to develop the role of medical institutions in the various units within the corresponding medical resources, thereby controlling health care resources can be used by users, access rights, use range, then the role assigned to the user roles and permissions session to address users (patients, medical institutions staff) role conflict. In practical operation, the study will be designed to integrate medical resources and services, used in medical IT environment. Practical operation, the design of medical resources integration platform architecture applied Swift implementation of multi-tenant environments, simulated situations medical institutions and medical resources simulate conflict, blending experimental allocation of medical resources, segregation of duties and other dynamic relationship comparison. For medical institutes to provide cloud computing environment to help medical institutions to achieve integration and consistency. Combine Dynamic Separation of Duty with the multi-tenancy and using service level agreements (SLA) to find out the conflict point ,design the rule of Dynamic Separation of Duty that suits medical resources situation and prevent Multi-tenancy conflict.
