A Federated Privacy-Enhancing Identity Management System (FPE-IMS)

Privacy and identity management should not been treated as generic problems providing generic solutions and architectures. A systematic approach is required against the problems of conducting identity management effortlessly, conveniently and smoothly solving interoperability problems that impede the communication and creation of unified infrastructures and produce an interoperable solution for identity management. This paper aims to contribute towards the proposal of a federated privacy-enhancing identity management system providing all the main tools and services in order address the major privacy requirements, required for the achievement of privacy aware e/m-transactions. This system can be embedded to each reconfigurable framework, enhancing privacy issues on existing web services based platforms, which delivers privacy-aware e/m-organizational services.

Innovative, Secure and Interoperable E/M-Governmental Invoicing

Research into initiatives worldwide shows that although some of the legal and organizational barriers for the adoption of new technologies in e/m-government have been lifted, there are still not many implementations of actual e/m-government services that have been designed based on a common and systematic approach. The most prevailing requirements for e/m-government services, interoperability and security, pose major challenges to e/m-government architects and it is now being slowly understood that Web Services in combination with PKIs may provide the necessary solutions. In this context, this paper presents an innovative e/m-government service based on these technologies, focusing basically on their security and interoperability aspects. The goal of the paper is to demonstrate the services specifications and use cases so that it may act as example for further research and development.

A Secure Mobile Framework for m-Services

Public key infrastructures (PKIs) is recommended as the most appropriate solutions for achieving secure mobile services. This paper identifies the need for security in mobile communications and investigates the use of lightweight protocols such as the XML Key Management (XKMS) protocol for accessing PKI services. Finally it presents a secure mobile framework based on XML and Web Services-technologies and standards that adopts these protocols.

Open issues on privacy and trust in collaborative environments

Exploiting the advantages of Web 2.0 technologies and collaborative applications and tools such as wikis, blogs, forums, real-time text editors and other groupware systems, modern services and Information Systems have evolved towards collaborative and social environments where user-generated content is a common task. In this paper we will identify the additional privacy and trust requirements posed by collaborative knowledge tools and suggest a number of guidelines for the development of privacy-aware Identity and Access Management systems that are capable to ensure trust in the context of collaborative workspaces.

Design principles of secure federated e/m-government framework

The implementation of large-scale enterprise frameworks for providing advanced e/m-government services necessitates the clear specification, the address, and maintenance of core fundamental design principles, strategies and guidelines. These will accelerate and assure the catch of common goals and benefits such as, to increase intrinsic interoperability, federation, vendor diversification options, business and technology domain alignment, organisational agility, and reduce IT burden. This paper proposes a synchronous e/m-government SOA framework, giving constant emphasis on how and where fundamental design principles are applied with the ultimate goal of producing high quality, secure and interoperable governmental, added-value services.

ODYSSEUS: An Advanced, Collaborative and Trusted Framework for the Provision of Migration Services

Migration policy making and monitoring constitute critical issues for European countries, given the impact of modern phenomena such as illegal employment on economic growth and future prosperity. The dynamic and complex nature of migration problems demands common approaches and collaborative actions among all stakeholders both at National and European level. Policy and decision makers need to systematically collaborate towards sophisticated approaches that facilitate legal immigrants to be effectively integrated in labor markets and public administration processes. Existing research initiatives and migration-oriented automated tools and services fail to provide a complete, robust and widely available framework for the collaborative development of common pan-European migration policies and the harmonization of processes and documents formats. Identifying these weaknesses as well as the need for enabling and supporting legal immigrants to be informed and provide their valuable feedback, this paper focuses on the description of a web-based communication framework for open collaboration on migration issues. The proposed system, ODYSSEUS, aims at enhancing existing Migration Information Systems by providing an advanced, collaborative and trusted framework for the provision of migration services.

Collaborative, Trusted and Privacy-Aware e/m-Services

This book constitutes the refereed conference proceedings of the 12th IFIP WG 6.11 Conference on e-Business, e-Services and e-Society, I3E 2013, held in Athens, Greece, in April 2013. The 25 revised papers presented together with a keynote speech were carefully reviewed and selected from numerous submissions. They are organized in the following topical sections: trust and privacy; security, access control and legal requirements in cloud systems; protocols, regulation and social networking; adoption issues in e/m-services; new services adoption and ecological behavior; knowledge management and business processes; and management, policies and technologies in e/m-services.

Collaborative information and knowledge management environments: The ‘what’ and ‘how’

Information and knowledge management has obviously acquired immense value in business analysis and strategic planning. Targeting towards this direction, the role of collaborative systems and collective knowledge tools becomes highly important in supporting the exploitation of business knowledge and the harnessing of collective intelligence. Although existing technological advancement appears today more mature than ever in providing a stable technology framework, the use of which can lead to innovative knowledge management techniques and mechanisms, architects still struggle to define fundamental principles, strategies and integration approaches in designing and implementing successful collaborative information and knowledge management environments. This article aims at identifying all critical operational and technical requirements posed by such demanding enterprise solutions, and presents an overall system architecture that demonstrates all their indispensable characteristics. In addition, it proposes effective integration practices for achieving a greater level of maturity and predictability when building modern collaborative information and knowledge management environments.

Migration-aware policy-making in decentralised and dynamic social and collaborative environments

Migration for employment is acknowledged to have direct consequences on National economies, as well as the overall economic situation of the European Union (EU). Migration policy and decision-makers need to systematically collaborate towards sophisticated approaches that facilitate legal immigrants to be effectively integrated in labour markets and public administration processes. Latest ICT developments, which integrate Web 2.0 technologies, collaborative knowledge management systems, and semantic analysis technologies, allow participatory governance and citizen-generated policy making. This paper presents a collaborative migration policy-modelling centre, techniques, solutions and overall services for collaborative development of immigration policies, as well as for supporting related decisions.

Assessment of advanced cryptographic antiviral techniques

The engineering world appears today more mature than ever in providing stable technology premises in order to build large scale, real interoperable and secure enterprise information systems, and strengthening the fundamental structure of private and public organisations. However, as technology has evolved, more opportunities have become available for virus writers to express their imagination in malicious code. Computer viruses are a major problem in modern day computing, threatening the structure of organisations, their enterprise systems and eliminating user-acceptance of electronic and mobile services provided. Detection tools such as virus scanners have performed poorly, particularly when facing previously unknown virus or novel variants of existing ones. This paper proposes and performs assessment on advanced proactive and reactive cryptographic measures that ensure the robustness and security of enterprises and computer systems.
