Today’s talks covered a variety of topics, from effective and efficient strategies for managing RFID data in the supply chain, to a framework for security in interoperable RFID networks, to probabilistic RFID data cleaning and even RFID in mobile E-commerce.

One interesting talk on “Interoperable Internet Scale Security Framework for RFID Networks” was given by Tingting Mao at the MIT AUTO-ID lab. This work describes a framework whereby businesses can define policies for sharing EPC data and the associated business events. A key feature of this system is that it uses authentication and authorization based on an aggregation of business rules, enterprise information, and RFID tag information. In another talk, Antti Sirkka from TietoEnator discussed “Modelling Traceability in the Forestry Wood Supply Chain”. This work aims to use RFID to improve information on processes in the forestry wood production system – a pressing problem given the equivalent of Є5 billion of wood raw material going to waste in Europe.

There were also great talks and discussion from panelists Yanlei Diao (University of Massachusetts, Amherst) and Fusheng Wang (Siemens Corporate Research).

Slides from the talks will eventually be posted online at: http://rfid.cs.washington.edu/rfdm08/
