Communities, Mobilität und Datenschutz : innovative Konzepte zum Schutz der Privatsphäre im Projekt PICOS

Plattformen für Social Communities im Internet, wie Facebook, StudiVZ und XING, haben in den vergangenen Jahren rasant an Popularität gewonnen. Auf ihnen versammeln sich bereits heute Millionen von Nutzern weltweit. Sie verbinden sich über virtuelle Freundeslisten und tauschen sich über gemeinsame Interessen und Aktivitäten aus. Immer häufger werden dazu auch mobile Endgeräte wie Handys verwendet, erlauben diese doch ständig in Kontakt mit der Community zu bleiben. Allerdings wollen viele Nutzer längst nicht jedem Mitglied einer Community alles preisgeben. Doch wie lässt sich die Privatsphäre in solchen Communities besser schützen? Dieser Frage geht das Forschungsprojekt PICOS nach

Mobile Brokerage Infastructures - Capabilities and Security Requirements

This paper investigates the potential of integrated mobile financial information and transaction services which can help private investors in making time-critical investment decisions and portfolio transactions in time. The analysis of intraday stock price reactions following company announcements provides evidence regarding the added value of such services if abnormal price movements can be observed. As efficient capital markets react very quickly to new information available, private investors require combined mobile notification and transaction services. So far, existing concepts can not fulfill these requirements which results from inappropriate implementation of the security mechanisms in order to realize secure and trustworthy processing. After identifying potential weaknesses of current solutions we introduce an adequate system infrastructure which can realize secure information and transaction processing in time by permitting a smart integration of notification and transaction services

Earning Money - A Situation Based Approach for Mobile Business Models

Current mobile business models for mobile commerce do not seem promising with regard to substantial revenue streams for mobile network operators as well as mobile service providers. Today’s settings require customers to “invest” into data transmission before being able to enter a mobile service, i.e. they are forced to pay for all data transmitted regardless whether this data is valuable content or just unwanted marketing messages. In this paper we propose a new business model, which allows mobile service providers to use information about the customer by situation based profiling in order to identify high value customers and sponsor their data transmission costs. It is shown, that by applying this approach revenue streams can be increased significantly for all parties involved, contributing to a more positive perspective for future developments in the mobile market

The impact of Human Choice and Computers and Technical Committee 9 on ICTs and society : a critical sociotechnical tale

In this chapter we briefly recount the history of the Human Choice and Computers conference series, and of Technical Committee 9, and show that not only has there been a marked focus, over more than four decades, on a critical and sociotechnical approach to understanding the relationship be-tween ICTs and society, but that HCC and TC9 might be regarded as the original and continuing home of the critical academic voice in ICT. We show this through a textual analysis of the proceedings of the conferences, and through biographical detail concerning the key players involved
