ENABLING COLLABORATIVE E-HEALTH THROUGH TRIPLESPACE COMPUTING

Abstract The design and promotion of electronic patient summaries as an instrument to facilitate the pervasive delivery of healthcare is emerging as a key technology in eHealth solutions. From the technical point of view this requires powerful middleware systems supporting interoperability, multi-lingualism, security and patient privacy. In this paper we present a semantic coordination model and describe how it can be used to support pervasive access to electronic patient summaries

DESIGN AND IMPLEMENTATION OF A SECURED PERSONAL IDENTITY BASED ECC AND ECDSA: AN INPATIENT SYSTEM

In this research, we developed an e-health system for cases of patient's hospitalization. This system was integrated with an e-id based RFID. E-id contains patient's id, secret key, and personal identity that consist of strong and weak attributes. Strong attributes will be encrypted using ECC Method, while the authentication process will verify the validity of the patient’s personal identity using ECDSA method. The results show that the system which was developed has been able to protect the patient's personal identity. This is because strong attributes have been successfully encrypted. During the authentication process, the received message was authenticated. Therefore, the system that was developed is expected to increase the trust and confidence of patients

Quality framework for semantic interoperability in health informatics: definition and implementation

Aligned with the increased adoption of Electronic Health Record (EHR) systems, it is recognized that semantic interoperability provides benefits for promoting patient safety and continuity of care. This thesis proposes a framework of quality metrics and recommendations for developing semantic interoperability resources specially focused on clinical information models, which are defined as formal specifications of structure and semantics for representing EHR information for a specific domain or use case. This research started with an exploratory stage that performed a systematic literature review with an international survey about the clinical information modelling best practice and barriers. The results obtained were used to define a set of quality models that were validated through Delphi study methodologies and end user survey, and also compared with related quality standards in those areas that standardization bodies had a related work programme. According to the obtained research results, the defined framework is based in the following models: Development process quality model: evaluates the alignment with the best practice in clinical information modelling and defines metrics for evaluating the tools applied as part of this process. Product quality model: evaluates the semantic interoperability capabilities of clinical information models based on the defined meta-data, data elements and terminology bindings. Quality in use model: evaluates the suitability of adopting semantic interoperability resources by end users in their local projects and organisations. Finally, the quality in use model was implemented within the European Interoperability Asset register developed by the EXPAND project with the aim of applying this quality model in a broader scope to contain any relevant material for guiding the definition, development and implementation of interoperable eHealth systems in our continent. Several European projects already expressed interest in using the register, which will now be sustained by the European Institute for Innovation through Health Data

Enabling the European patient summary through triplespaces

One of the main items on the eHealth agenda of the European Community is the design and promotion of electronic patient summaries as an instrument to guarantee the continuity of healthcare across national boundaries and to facilitate the pervasive delivery of healthcare, thus ensuring the right to patient mobility and increasing the productivity and quality of health service delivery. From a technical point of view, this objective requires middleware technology which is able to cope with the stringent interoperability, multi-lingualism, distribution, and privacy requirements arising in eHealth settings. This paper presents triplespace computing, a coordination middleware for the Semantic Web,and demonstrates its relevance to the realization of the European Patient Summary, an infrastructure for sharing and coordinating access to patient summaries at the European level
