Der vorliegende Beitrag stellt die Entwicklung und Einführung einer Software zur Unterstützung kollaborativer Reflexion am Arbeitsplatz vor. Dabei wurden schon während früher Entwicklungsphasen Datenschutzfragen viel Raum eingeräumt und im weiteren durch enge Einbindung verschiedener Akteure, etwa durch Workshops und Fragebögen, versucht theoretische Konzepte des Privacy By Design in den agilen...

In certain circumstances an individual may not be in control of their private location information and thus vulnerable to a privacy violation. In this paper, we ensure location privacy through the establishment of a prohibitive contract in a situation where an individual wishes to minimize privacy loss and a service provider aims to maximize profits. Given the possible strategies we show that a...

The improvement of energy efficiency is an important target on all levels of society. It is best achieved on the basis of locally and temporally fine-grained measurement data for identifying unnecessary use of energy. However, at the same time such fine-grained measurements allow deriving information about the persons using the energy. In this paper we describe our work towards a privacy preser...

Today, simple analogue assistive technologies are transformed into complex and sophisticated sensor networks. This raises many new privacy issues that need to be considered. In this paper, we investigate how this new generation of assistive technology incorporates Privacy by Design (PbD) principles. The research is conducted as a case study where we use PbD principles as an analytical lens to i...
