Our research work presents findings from literature review and expert interviews with more detailed knowledge of privacy-sensitive data in connected cars. At first we explore which privacy-sensitive data are collected in cars and how they are collected. Then we describe who receives the data, for what purposes and how car users can determine if their privacy-sensitive data are being collected and...
Based on Jadhav and Sonars' model for the selection of software we develop a catalogue of criteria for the comparison of software solutions for high-security voice and data communication for smartphones. Our catalogue consists of five categories: functionality, quality, vendor, cost-benefit ratio and terminal equipment/infrastructure. For each category we define criteria and sub-criteria. Based on...
The market of security software solutions for smartphones has grown considerably in the last few years. A wide range of products is available. The objective of our work is to develop an overview of security software solutions for smartphones. At first we identify basic threats and typical security measures for smartphones. Then we explore current security software solutions and describe how these...

This paper presents findings of a threat analysis of data transmission over GSM/UMTS networks. We explore typical threats of mobile data transmission and describe their possible consequences related to security objectives like confidentiality, availability, and integrity. Furthermore, we develop a catalog of technical and organizational security measures and consider which threats can be prevented...
The paper presents first findings of a study in wireless LAN security (WLAN) in German companies and federal authorities. The study was conducted in spring 2009. We formulate hypotheses derived from several studies in WLAN security. We analyze how the situation in Germany fits these assumptions. Degree of familiarity, frequency of use and reasons for not using wireless LAN security measures are being...
Digital libraries are keystones for satisfying a specialized information demand. One big challenge for a successful digital library project is the consideration of the economic issues. We introduce an approach for the development of a revenue model. A case study for the DMG-Lib project is presented to show the practicability of our approach.
The impact of digital libraries on information processes is steadily growing. Today, a rapidly increasing number of digital libraries with various characteristics are available. Business models for digital libraries evolve from mere content providers to sophisticated service suppliers. They offer a rich variety of information services combined with collaboration, e-learning and portal features. Traditional...
