'Personal Healthcare Records' (PHR) is a service for providing individual clinical data to patients. PHR service should be useful for the patient and healthcare service providers. This study has aimed at not only providing patients' clinical data but also developing optimized healthcare service for every patients. The research has been conducted as 3 phases: formal case analysis, caregivers interviews and patients interviews. The patients interviews were limited to cancer patients. As results, 3 key functions have been developed. First, it offers patient's clinical pathway as a personalized medical treatment scheduler. Second, it supplies Question & Answer board on online. Last, it supports patients to input their healthcare record. This Myongji PHR service has 3 months of pilot test on web and mobile application(android version). For further commercialized PHR service, the standardization for clinical pathway registration and user convenience need to be considered.

Personal Health Records(PHR) service offers patients a convenient and easy-to-use solution for managing their personal health records, crucial medical files, and emergency contacts. In spite of the indispensable advantages, PHR service brings critical challenges that cannot be avoided from consumer side if the security of the data is concerned. The problem of user's privacy infringement and leaking user's sensitive medical information is increasing with the fusion of PHR technology and healthcare. In this paper, therefore, we analyze the various security aspects that are vulnerable to the PHR service and needed to be resolved. Moreover, we analyze the security requirements from the point of view of the PHR users and application service providers and provides the PHR security mechanism for addressing PHR security threats and satisfying PHR security requirements.

PHR is integrated into the server, so the problem has managed. Thus, the highly sensitive information stored on the server. PHR should be limited to the access rights. In this paper, the access rights of PHR as a way to distinguish the role of each approach based on a distributed hierarchical key to ensuring the privacy of PHR by key distribution protocol is proposed.

PHR(Personal Health Record) to support the lifelong healthcare of their medical information to consumers anytime, anywhere can view and manage health information to help direct input can be defined as a service. The PHR is to provide services efficiently and PHR systems and health-related information systems should be integrated and linked. However, the current healthcare information systems field in order to meet the growing demand for healthcare construction and operation of various systems, and accordingly continues to increase budget for information, but the current system, although the association between a variety of system integration and linkage is being made. This paper proposes a Integrated information system on Healthcare based on Web service to solve problems mentioned above. SOA(Service Oriented Architecture) is a major method of integrating services on the Web. It enables new requirements to be added to existing systems without modification of legacy services, so it makes rapid adaption to varying business environment. Therefore, In this paper, PHR services based on SOA as a platform for the health care sector to design and implement an integrated information system by web services based PHR services for the construction of a new integrated information system is proving to be a suitable model.

With the advance of Information Technology (IT) and dynamic requirements, diverse application services have been provided for end users. With huge volume of these services and information, users are required to acquire customized services that provide personalized information and decision at particular extent of time. The case is more appealing in healthcare, where patients wish to have access to their medical record where they have control and provided with recommendation on the medical information. PHR (Personal Health Record) is most prevailing initiative that gives secure access on patient record at anytime and anywhere. PHR should also incorporate decision support to help patients in self-management of their diseases. Available PHR system incorporates basic recommendations based on patient routine data. We have proposed decision support service called "Smart CDSS" that provides recommendations on PHR data for diabetic patients. Smart CDSS follows HL7 vMR (Virtual Medical Record) to help in integration with diverse application including PHR. PHR shares patient data with Smart CDSS through standard interfaces that pass through Adaptability Engine (AE). AE transforms the PHR CCR/CCD (Continuity of Care Record/Document) into standard HL7 vMR format. Smart CDSS produces recommendation on PHR datasets based on diabetic knowledge base represented in shareable HL7 Arden Syntax format. The Smart CDSS service is deployed on public cloud over MS Azure environment and PHR is maintaining on private cloud. The system has been evaluated for recommendation for 100 diabetic patients from Saint's Mary Hospital. The recommendations were compared with physicians' guidelines which complement the self-management of the patient.

It is needed to support intelligent customized health information service for user convenience in PHR based Personal Health Care Service Platform. In this paper, we specify an ontology-based health data model for Personal Health Care Service Platform. We also design a knowledge search algorithm that can be used to figure out similar health record by applying machine learning and data mining techniques. Axis-based mining algorithm, which we proposed, can be performed based on axis-attributes in order to improve relevance of knowledge exploration and to provide efficient search time by reducing the size of candidate item set. And K-Nearest Neighbor algorithm is used to perform to do grouping users byaccording to the similarity of the user profile. These algorithms improves the efficiency of customized information exploration according to the user 's disease and health condition. It can be useful to apply the proposed algorithm to a process of inference in the Personal Health Care Service Platform and makes it possible to recommend customized health information to the user. It is useful for people to manage smart health care in aging society.

We developed a Smartphone application based on PHR(Personal Health Records) provided by a tertiary hospital to provide users personalized diet, exercise contents. It uses Relevance ratio algorithm of diet and excercise being correlated with diseases listed on PHR to provide personalized contents to management of individual diseases and record the amounts of food taken and exercise along with calories consumed through exercise. Besides, developed U-Health Service also considering users' conditions and conveniences, as a service to use contents and record suitable for the individuals who share the information on restaurants locations, their menus, and nutrition based on users' location information.

In the 4th Industrial Revolution, the healthcare industry is undergoing a paradigm shift from post-care and management systems based on diagnosis and treatment to disease prevention and management based on personal precision medicine. To optimize medical services for individual patients, an open ecosystem for the healthcare industry that allows the exchange and utilization of personal health records (PHRs) is required. However, under the current system of hospital-centered data management, it is difficult to implement the linking and sharing of PHRs in practice. To address this problem, in this study, we present the design and implementation of a patient-centered PHR platform using blockchain technology. This platform achieved transparency and reliability in information management by eliminating the risk of leakage and tampering/altering personal information, which could occur when using a PHR. In addition, the patient-consent system was applied to a PHR; thus, the patient acted as the user with ownership. The proposed blockchain-based PHR platform enables the integration of personal medical information with scattered distribution across multiple hospitals, and allows patients to freely use their health records in their daily lives and emergencies. The proposed platform is expected to serve as a stepping stone for patient-centered healthcare data management and utilization.
