The availability of individual load profiles per household in the smart grid end-user domain combined with non-intrusive load monitoring to infer personal data from these load curves has led to privacy concerns. Privacy-enhancing technologies have been proposed to address these concerns. In this paper, the extension of privacy-enhancing technologies by wavelet-based multi-resolution analysis (M...

Privacy risks have been addressed through technical solutions such as privacy-enhancing technologies (PETs) as well as regulatory measures including Do Not Track. These approaches are inherently limited as they are grounded in the paradigm of a rational end user who can determine, articulate, and manage consistent privacy preferences. This implies that self-serving efforts to implement individu...

The paper introduces an approach to privacy enhancing technologies that sees privacy not merely as an individual right, but as a public good. This understanding of privacy has recently gained ground in the debate on appropriate legal protection for privacy in an online environment. The jurisprudential idea that privacy is a public good and prerequisite for a functioning democracy also entails t...

Satellites had been successful in the past due to their wide area coverage and speedy deployment of new services especially in remote regions of Europe and the rest of the world. The future development of broadband satellite systems providing services based on the Internet Protocol (IP) needs to be stimulated by means of common standards. This paper presents the ETSI BSM PEP architecture which ...

The move towards service-oriented architectures and the increasing usage of mobile devices to access such services are two of the major changes in modern computing. Information about the user, their location and their trajectory can provide additional context information to a service, leading to useful applications such as directing a user to the nearest bus stop and displaying which buses are ...

Satellite link characteristics cause reduced performance in TCP data transfers. In this paper we present SaTPEP, a TCP Performance Enhancing Proxy which attempts to improve TCP performance by performing connection splitting. SaTPEP monitors the satellite link utilization, and assigns to connections window values that reflect the available bandwidth. Loss recovery is based on Negative Acknowledg...

Privacy-enhancing technologies can be used to enhance the privacy of individuals who interact with information processing systems. This paper considers such technologies that can be used by the organisation to safeguard personal information it processes. The paper focuses on how access control could be used to protect the individual against misuse of personal data inside the organisation. More ...

The peculiar characteristics of the satellite links affect performance of the TCP protocol, largely used by most of the Internet applications. Then, to achieve good performance TCP Performance Enhancing Proxy mechanisms are often used. In principle, a TCP PEP mechanism accelerates TCP transfers requiring access to TCP headers in intermediate nodes. As a drawback, this conflicts with IPsec, whic...

This paper presents a new Forward Error Correction Scheme with several priority levels. It is useful for applications dealing with real-time transport streams like video and audio. Those streams consist of several data parts with diierent importance. PET allows to protect those parts with appropriate redundancy and thus guarantees, that the more important parts arrive before the less important ...

As a pivotal task in cancer therapy, outcome prediction is the foundation for tailoring and adapting a treatment planning. In this paper, we propose to use image features extracted from PET and clinical characteristics. Considering that both information sources are imprecise or noisy, a novel prediction model based on Dempster-Shafer theory is developed. Firstly, a specific loss function with s...
