The primary focus of the UK e‐Science Programme is the development of software architectures, middleware and applications to support the end‐user scientific community in the undertaking of large‐scale research. A significant subset of e‐Science projects is concerned with the healthcare domain: as well as satisfying the needs of the end users, such projects have to consider the legal, ethical and security constraints associated with the use of sensitive patient data—these concerns are particularly relevant within the context of the U.K.'s National Health Service (NHS). In this paper we present a vision for Grid‐enabled healthcare that is sensitive to the information security requirements both of the NHS and the projects themselves. Although our motivation is principally derived from U.K.‐based e‐Health projects, this paper should be of interest to the worldwide health Grid community. By restricting ourselves to information security, we do not consider, for example, physical security or audit trail capabilities, which are outside the scope of this paper. The vision we describe is grounded in terms of experience, and reflects the challenges faced by the e‐DiaMoND project team. Copyright © 2005 John Wiley & Sons, Ltd.

Blockchain's evolution during the past decade is astonishing: from bitcoin to over 2.000 altcoins, and from decentralised electronic payments to transactions programmable by smart contracts and complex tokens governed by decentralised organisations. While the new generation of blockchain applications is still evolving, blockchain's technical characteristics are also advancing. Yet, immutability, a hitherto indisputable property according to which blockchain data cannot be edited nor deleted, remains the cornerstone of blockchain's security. Nevertheless, blockchain's immutability is being called into question lately in the light of the new erasing requirements imposed by the GDPR's “Right to be Forgotten (RtbF)” provision. As the RtbF obliges blockchain data to be editable in order restricted content redactions, modifications or deletions to be applied when requested, blockchains compliance with the regulation is indeed challenging, if not impracticable. Towards ...

Abstract-In recent years, research and presentation of cultural heritage have an important ally: technology. The "Ark of Refugee Heirloom" is a project of high cultural importance, since it aims at the recording and documentation of unknown heirlooms, kept mainly in private collections. The objective is the classification and publication of primary data, in order to support further research on the field of Cultural Heritage. The project tracks down heirlooms in the five prefectures of Eastern Macedonia and Thrace that belong to refugees whose origins lay in regions of the Ottoman Empire, south Russia, Bulgaria and others surrounding the Black Sea.

The principle aim of the e-DiaMoND project is to develop a prototype Grid infrastructure to support the needs of the breast care community. The prototype system is but one major deliverable of the project; the other is a blueprint document that describes how a system such as e-DiaMoND might be deployed throughout the United Kingdom to support the NHS Breast Screening Programme. A key consideration of both the prototype and the blueprint document is security. We provide a summary of the generic security issues faced by e-Health projects such as e-DiaMoND. 1.

By applying the latest technologies in image compression for managing the storage of massive image data within cultural heritage databases and by exploiting the universality of the Internet we are now able not only to effectively digitize, record and preserve, but also to promote the dissemination of cultural heritage. In this work we present an application of the latest image compression standard JPEG2000 in managing and browsing image databases, focusing on the image transmission aspect rather than database management and indexing. We combine the technologies of JPEG2000 image compression with client-server socket connections and client browser plug-in, as to provide with an all-in-one package for remote browsing of JPEG2000 compressed image databases, suitable for the effective dissemination of cultural heritage.

In this paper we discuss the use of XACML policies to describe access control for use in health grids. We discuss the motivations for the use of role-based access control (RBAC) in a medical context. Using a simple motivating example we consider the use of the RBAC profile for XACML and discuss the limitations of the current profile. Finally, we discuss various solutions to providing fully flexible RBAC support in XACML, and consider their impact on the existing language. 1.

Overview This e-DiaMoND blueprint document serves two key purposes: the first is that, by complementing the e-DiaMoND prototype and the research data collected during the project, it constitutes the third major deliv-erable from the two-year e-DiaMoND project; the second is that this document should provide the basis of a framework for projects—both technological and clinical—that might follow on from e-DiaMoND. The original intention of this document was that it would determine how a full e-DiaMoND system might be deployed within the UK to support the National Health Service Breast Screening Programme. For example, such a system would have to be capable of interfacing with systems already operating within the National Health Service and would also have to meet the legal and ethical requirements associated with the storage and transfer of medical data. Recent developments have made the full deployment of such a system—at least within the foreseeable future—unlikely. As such, a signi...

The incremental divergence between the Data Protection Directive 95/46/EC and the massive world changes in all spheres, effectively saw the obsolescence and inapplicability of the previous law, with regards to the relationship between business and consumer. The preceding law was a directive, which is different from a regulation. The directive was implemented differently in every EU country, while a regulation applies equally across all member states of the European Union and EU economic areas.
