A Peer-To-Peer Approach for Resolving RFIDs

We present a system using a Peer-to-Peer network for re- solving associations of Radio Frequency Identification (RFID) tagged objects to their virtual presence. A query, which consists of an identification string, is sent to the net- work and receives the appropriate resolution data. We pay particular attention to the authenticity and security of the exchanged data, in order to prevent tracing of resolution queries. The usage of a Peer-to-Peer network enables an non-authoritarian yet easily managed extension by further resolving services, such that these services do not need to share any information with an authoritative organization. Supply Chain Management (SCM) and Customer Relation- ship Management (CRM) represent potential application areas.
