Mobil bilgi işleme dayalı tıbbi bulut veri tabani servis sisteminin tasarımı ve uygulanması

In modern healthcare environments, a fundamental requirement for achieving a ubiquitous system is the provision of an easy access to a distributed health records of patients at the point of healthcare or treatment in a unified and integrated manner in the cloud. Nevertheless, integrating crucial patient health records from different hospitals at a center in the cloud raises concerns about security, privacy and authorization measures to be implemented. In this work NFC (Near Field Communication) technology is presented to prevent attacks. NFC allows secure exchange of small amounts of data by proximity or touch. In addition, access control measures must guarantee that only authorized users have access to such Critical records and for a legitimate motives, or otherwise for illegimate motives and unauthorized users, access to the records must be denied at the data center. The aim of this paper is to propose a unified access control scheme capable of supporting a selective sharing of patients compounded electronic health records (EHRs), by using different standards of granularity and more importantly providing the required privacy protection and security for the aggregated data. Moreover, for mobility and easy access, a medical passport card system is proposed using NFC technology. A simulation work of a normal healthcare service system and a comparison of that to the proposed system has been carried out, which showed a more advancement in the treatment process and at the same time cost effective.
