Anonymous network access using the digital marketplace

With increasing usage of mobile telephony, and the trend towards additional mobile Internet usage, privacy and anonymity become more and more important. Previously-published anonymous communication schemes aim to obscure their users' network addresses, because real-world identity can be easily be derived from this information. We propose modifications to a novel call-management architecture, the digital marketplace, which will break this link, therefore enabling truly anonymous network access

Individual Risk Management for Digital Payment Systems

Despite existing security standards and security technologies, such as secure hardware, gaps between users’ demand for security and the security offered by a payment system can still remain. These security gaps imply risks for users. In this paper, we introduce a framework for the management of those risks. As a result, we present an instrument enabling users to evaluate eventual risks related with digital payment systems and to handle these risks with technical and economic instruments.Payment Systems, Digital Money

Systematizing Decentralization and Privacy: Lessons from 15 Years of Research and Deployments

Decentralized systems are a subset of distributed systems where multiple authorities control different components and no authority is fully trusted by all. This implies that any component in a decentralized system is potentially adversarial. We revise fifteen years of research on decentralization and privacy, and provide an overview of key systems, as well as key insights for designers of future systems. We show that decentralized designs can enhance privacy, integrity, and availability but also require careful trade-offs in terms of system complexity, properties provided, and degree of decentralization. These trade-offs need to be understood and navigated by designers. We argue that a combination of insights from cryptography, distributed systems, and mechanism design, aligned with the development of adequate incentives, are necessary to build scalable and successful privacy-preserving decentralized systems

Identity Management in Information Age Government: Exploring Concepts, Definitions, Approaches and Solutions

Our research question is the following: What could be a useful working definition of Identity Management in government at present? a) What are conceptualisations, definitions and approaches of IDM in government according to academic literature? b) Which e-authentication solutions have been developed in other jurisdictions
