Building Consumer Trust in Pervasive Retail 
George Roussos (University of London, UK)

Abstract. At the core of the vision of pervasive computing lies the ability to augment physical artefacts with electronic properties and to create physical manifestations of electronic entities. The first widely available technology to offer this capability is RFID. When combined with the EPC Global network it is possible to track products from the time of manufacture until the consumer waste bin. To be sure, this development offers unique opportunities for the transformation of the shopping experience. Yet, it also brings considerable dangers in that consumersf activities can also be tracked and their privacy violated. Even worse, this can happen without any visible sign and thus completely transparently to the consumer. It is no surprise then that RFID use has generated considerable concerns across the globe. In this lecture, I will explore consumer perceptions of pervasive retail and discuss approaches that can help develop consumer trust in RFID-based systems.

Interaction Design for Future Smart Environments
Norbert A. Streitz (Fraunhofer IPSI, Darmstadt, Germany)

Abstract. The design of smart environments is based on the idea to integrate information technology, especially sensor technology as, e.g., RFID in everyday objects and combine the resulting smart artefacts into ensembles populating architectural spaces as, e.g., so called Cooperative Buildings. The integration is not limited to sensors but to a range of devices. The computer "disappears" as a device but its functionality is ubiquitously available and provides new forms of interacting with information. Our approach is to develop environments that exploit the affordances of real everyday objects and at the same time use the potential of computer-based support. Combining the best of both worlds requires an integration of real and virtual worlds resulting in hybrid worlds. In my talk, I will first present prototypes illustrating our Roomware® concept focussing especially on two examples (Passage, ConnecTable) exploiting sensor technology. This is followed by giving an overview of the EU-funded proactive initiative "The Disappearing Computer" (DC), a cluster of 17 related projects designing new people-friendly environments in which the "computer-as-we-know-it" has no role. Finally, I present results from the DC-project "Ambient Agoras: Dynamic Information Clouds in a Hybrid World". It aims at transforming places into social marketplaces ('agoras') of ideas and information. This is achieved by developing combinations of ambient displays and mobile devices. I will show examples of smart artefacts (Hello.Wall, ViewPort, Personal Aura) that address especially the possibilities of being sensed in smart environments and the related issue of privacy. One application scenario is the support of informal communication between remote teams at different locations using ambient displays.

Bio. Dr. Dr. Norbert Streitz (Ph. D. in physics and Ph.D. in psychology) is the head of the research division "AMBIENTE - Smart Environments of the Future" at the Fraunhofer institute IPSI in Darmstadt, Germany, where he also teaches at the Department of Computer Science of the Technical University Darmstadt. He was a post-doc fellow at the University of California, Berkeley and a visiting scholar at Xerox PARC and at the Intelligent Systems Lab of ETL-MITI, Tsukuba Science City. He is the Chair of the Steering Group of the EU-funded research initiative "The Disappearing Computer" and was co-chair of CONVIVIO: the EU-funded Network of Excellence on People-Centred Design of Interactive Systems. His research interests include Cognitive Science, Human-Computer Interaction, Hypertext/ Hypermedia, Computer-Supported Cooperative Work, Interaction Design, Ambient/Pervasive/Ubiquitous Computing. He has published/edited 16 books and authored more than 100 technical papers. He serves regularly on the program committees of national and international conferences and on several editorial boards and is often invited to present keynote speeches to scientific as well as commercial events in Europe, USA, South America, Malaysia, Singapore, and Japan.

Privacy Concerns and Traceability in RFID System
John Ayoade (National Institute of Information and Communications Technology, Japan)

Abstract. There is a possibility of modification of information contained in the transponder when necessary authentication procedure is not established. Moreover, illegal access to the tag by a malicious reader could create innumerous threats to the user's privacy. In this paper, we are focusing on finding solution to the illegal access of reader into the transponder/tag and more importantly considering the importance of tracing and tracking the illegal access in RFID system. A good authentication procedure is necessary and this is the reason why we proposed APF- Authentication Processing Framework. APF is an authentication framework that will register every reader before it can access any transponder.

Tea Gardens: RFID and Common Pool Resources
Andrew Wilson (The Media Centre, UK)

Abstract. This paper outlines popular concerns about RFID technology and its implications for privacy and civil liberties. These concerns are based on the assumption that RFID will be used for "top down" surveillance by governments and corporations against individual citizens. This assumption is contrasted with Elinor Ostrom's work on the self-organised "bottom up" management of Common Pool Resources, such as irrigation water and fish stocks, which rely on mutual monitoring, or "peer to peer" surveillance, to preserve these renewable resources. A role for wireless sensor technology in lowering the transaction costs of mutual monitoring is proposed. The paper then describes a practical experiment using RFID to manage a simple but unusual CPR.
