IMPROVING PRIVACY IN SHARING OF PERSONAL HEALTH DATA STORAGE ON CLOUD

PHRs grant patients access to a wide range of health information sources, best medical practices and health knowledge. In patient centric secure sharing, patients will create, manage and control their personal health data from one place using the web. In cloud computing, it is attractive for the health record service providers to shift their patients data applications and storage into the cloud, in order to like the flexible resources and diminish the operational cost, but by storing health records in the cloud, the patients be unable to find physical control to their personal health data, which makes it required for each patient to encrypt the data prior to uploading to the cloud servers. Under encryption, it is difficult to achieve fine-grained access control to personal health data in a scalable and well-organized way. Existing cryptographic enforced access control schemes are mostly designed for the single-owner scenarios. In this, suggest a patient-centric frame work and a suite of mechanism for data access control to PHRs stored in semi-trusted servers. To allow fine-grained and scalable access control for PHRs, control attribute based encryption (ABE) techniques to encrypt every patients data. Different from earlier works in protected data outsourcing, center on the multiple data owner scenario, and separate the user in the system into multiple security domains that really decreases the key managing complexity for owners and users. In this way, a high degree of patient privacy is assured concurrently by developing multi-authority ABE

Connected Health User Willingness to Share Personal Health Data: Questionnaire Study

Abstract Background: Connected health has created opportunities for leveraging health data to deliver preventive and personalized health care services. The increasing number of personal devices and advances in measurement technologies contribute to an exponential growth in digital health data. The practices for sharing data across the health ecosystem are evolving as there are more opportunities for using such data to deliver responsive health services. Objective: The objective of this study was to explore user attitudes toward sharing personal health data (PHD). The study was executed within the first year after the implementation of the new General Data Protection Regulation (GDPR) legal framework. Methods: The authors analyzed the results of an online questionnaire survey to explore the willingness of 8004 people using connected health services across four European countries to share their PHD and the conditions under which they would be willing to do so. Results: Our findings indicate that the majority of users are willing to share their personal PHD for scientific research (1811/8004, 22.63%). Age, education level, and occupation of the participants, in addition to the level of digitalization in their country were found to be associated with data sharing attitudes. Conclusions: Positive attitudes toward data sharing for scientific research can be perceived as an indication of trust established between users and academia. Nevertheless, the interpretation of data sharing attitudes is a complex process, related to and influenced by various factors
