f-DP has recently been proposed as a generalization of differential privacy allowing lossless analysis composition, post-processing, and amplification via subsampling. In the setting f-DP, we propose concept canonical noise distribution (CND), first mechanism designed for an arbitrary guarantee. The notion CND captures whether additive perfectly matches guarantee given f. We prove that always e...

This paper presents the extension of an audio watermarking approach to the blind detection of multiple watermarks. The underlying statistical watermarking method working in the fourier domain with different test functions is investigated. The extension of this semiprivate watermarking method to enable a blind detection is presented. To enable the embedding of multiple watermarks the algorithm d...

A fundamental assumption in this article is that not only the public administration but also semiprivate and private agencies provide electronic intermediaries between public services and citizens in a quasi-market situation. The theoretical framework of this study views markets as constructed in contrast to natural phenomena. In these processes of construction the role of technologies such as ...

Pointing on public displays is usually done in a relative and indirect fashion. However, such techniques have two drawbacks: first, a personal pointer is shown on the public screen which decreases the users’ privacy in selection tasks. And second, when multiple displays are present, users need to connect to the one they want to interact with a priori. In this paper we review the strengths of To...
