Design and implementation of a secure and user-friendly broker platform supporting the end-to-end provisioning of e-homecare services

We designed a broker platform for e-homecare services using web service technology. The broker allows efficient data communication and guarantees quality requirements such as security, availability and cost-efficiency by dynamic selection of services, minimizing user interactions and simplifying authentication through a single user sign-on. A prototype was implemented, with several e-homecare services (alarm, telemonitoring, audio diary and video-chat). It was evaluated by patients with diabetes and multiple sclerosis. The patients found that the start-up time and overhead imposed by the platform was satisfactory. Having all e-homecare services integrated into a single application, which required only one login, resulted in a high quality of experience for the patients

A systematic literature review of cloud computing in eHealth

Cloud computing in eHealth is an emerging area for only few years. There needs to identify the state of the art and pinpoint challenges and possible directions for researchers and applications developers. Based on this need, we have conducted a systematic review of cloud computing in eHealth. We searched ACM Digital Library, IEEE Xplore, Inspec, ISI Web of Science and Springer as well as relevant open-access journals for relevant articles. A total of 237 studies were first searched, of which 44 papers met the Include Criteria. The studies identified three types of studied areas about cloud computing in eHealth, namely (1) cloud-based eHealth framework design (n=13); (2) applications of cloud computing (n=17); and (3) security or privacy control mechanisms of healthcare data in the cloud (n=14). Most of the studies in the review were about designs and concept-proof. Only very few studies have evaluated their research in the real world, which may indicate that the application of cloud computing in eHealth is still very immature. However, our presented review could pinpoint that a hybrid cloud platform with mixed access control and security protection mechanisms will be a main research area for developing citizen centred home-based healthcare applications

The European Institute for Innovation through Health Data

The European Institute for Innovation through Health Data (i~HD, www.i-hd.eu) has been formed as one of the key sustainable entities arising from the Electronic Health Records for Clinical Research (IMI-JU-115189) and SemanticHealthNet (FP7-288408) projects, in collaboration with several other European projects and initiatives supported by the European Commission. i~HD is a European not-for-profit body, registered in Belgium through Royal Assent. i~HD has been established to tackle areas of challenge in the successful scaling up of innovations that critically rely on high-quality and interoperable health data. It will specifically address obstacles and opportunities to using health data by collating, developing, and promoting best practices in information governance and in semantic interoperability. It will help to sustain and propagate the results of health information and communication technology (ICT) research that enables better use of health data, assessing and optimizing their novel value wherever possible. i~HD has been formed after wide consultation and engagement of many stakeholders to develop methods, solutions, and services that can help to maximize the value obtained by all stakeholders from health data. It will support innovations in health maintenance, health care delivery, and knowledge discovery while ensuring compliance with all legal prerequisites, especially regarding the insurance of patient's privacy protection. It is bringing multiple stakeholder groups together so as to ensure that future solutions serve their collective needs and can be readily adopted affordably and at scale

Cloud Computing in Healthcare – a Literature Review on Current State of Research

Nowadays, IT resources are increasingly being used in all areas of the health sector. Cloud computing offers a promising approach to satisfy the IT needs in a favorable way. Despite numerous publications in the context of cloud computing in healthcare, there is no systematic review on current research so far. This paper addresses the gap and is aimed to identify the state of research and determine the potential areas of future research in the domain. We conduct a structured literature search based on an established framework. Through clustering of the research goals of the found papers we derive research topics including developing cloud-based applications, platforms or brokers, security and privacy mechanisms, and benefit assessments for the use of cloud computing in healthcare. We hence analyze current research results across the topics and deduce areas for future research, e.g., development, validation and improvement of proposed solutions, an evaluation framework

A prototype and demonstrator of Akogrimo’s architecture: An approach of merging grids, SOA, and the mobile Internet

The trend of merging telecommunication infrastructures with traditional Information Technology (IT) infrastructures is ongoing and important for commercial service providers. The driver behind this development is, on one hand, the strong need for enhanced services and on the other hand, the need of telecommunication operators aiming at value-added service provisioning to a wide variety of customers. In the telecommunications sector, the IP Multimedia Subsystem (IMS) is a promising service platform, which may become a ''standard'' for supporting added-value services on top of the next generation network infrastructure. However, since its range of applicability is bound to SIP- enabled services, IMS extensions are being proposed by ''SIPifying'' applications. In parallel to these developments within the traditional IT sector, the notion of Virtual Organizations (VO) enabling collaborative businesses across organizational boundaries is addressed in the framework of Web Services (WS) standards implementing a Service-oriented Architecture (SOA). Here, concepts for controlled resource and service sharing based on WS and Semantic Technologies have been consolidated. Since the telecommunications sector has become, in the meantime ''mobile'', all concepts brought into this infrastructure must cope with the dynamics mobility brings in. Therefore, within the Akogrimo project the VO concept has been extended towards a Mobile Dynamic Virtual Organization (MDVO) concept, additionally considering key requirements of mobile users and resources. Especial attention is given to ensure the duality of the merge of both, SOA and IMS approaches to holistically support SOA-enabled mobile added-value services and their users. This work describes major results of the Akogrimo project, paying special attention to the overall Akogrimo architecture, the prototype implemented, and the key scenario in which the instantiated Akogrimo architecture shows a very clear picture of applicability, use, and an additional functional evaluation

Profile Management System in Ubiquitous Healthcare Cloud Computing Environment

A shift from the doctor-centric model to a patient-centric model is required to face the challenges of the healthcare sector. The vision of patient-centric model can be materialized integrating ubiquitous healthcare and the notion of personalization in services. Cloud computing can be the underlying technology for ubiquitous healthcare. The use of profiles enables the personalization in healthcare services and the use of profile management systems facilitates the deployment of these services. In this paper, we propose a profile management system in ubiquitous healthcare cloud computing environment. The proposed system exploits the cloud computing technology and the smart card technology to increase the efficiency and the quality of the provided healthcare services in the context of the patient-centric model. Furthermore, we propose generic healthcare profile structures corresponding to the main classes of the participating entities in a ubiquitous healthcare cloud computing environment

Service-Oriented Architecture for Patient-Centric eHealth Solutions

The world is in shortage of about 7.2 million healthcare workers in 2013, and the figure is estimated to grow to 12.9 million by 2035, according to the World Health Organization (WHO). On the other hand, the median age of the world’s population was predicted to increase from 26.6 years in 2000 to 37.3 years in 2050, and then to 45.6 years in 2100. Thus further escalating the need for new and efficient healthcare solutions. Telehealth, telecare, and Ambient Assisted Living (AAL) solutions promise to make healthcare services more sustainable, and to enable patients to live more independently and with a higher quality of life at their homes. Smart homes will host intelligent, connected devices that integrate with the Internet of Things (IoT) to form the basis of new and advanced healthcare systems. However, a number of challenges needs to be addressed before this vision can be actualised. These challenges include flexible integration, rapid service development and deployment, mobility, unified abstraction, scalability and high availability, security and privacy. This thesis presents an integration architecture based on Service-Oriented Architecture (SOA) that enables novel healthcare services to be developed rapidly by utilising capabilities of various devices in the patients’ surroundings. Special attention is given to a service broker component, the Information Integration Platform (IIP), that has been developed to bridge communications between everyday objects and Internet-based services following the Enterprise Service Bus (ESB) principles. It exposes its functionalities through a set of RESTfulWeb services, and maintains a unified information model which enables various applications to access in a uniform way. The IIP breaks the traditional vertical “silo” approach of integration, and handles information dissemination task between information providers and consumers by adopting a publish/subscribe messaging pattern. The feasibility of the IIP solution is evaluated both through prototyping and testing the platform’s representative healthcare services, e.g., remote health monitoring and emergency alarms. Experiments conducted on the IIP reveal how performance aspects are affected by needs for security, privacy, high availability, and scalability
