Abstract: An implementation wherein RFID data is shared across independent organizations has been addressed. RFID data is usually spread across different parties, e.g. enterprises in a supply chain and thus, efficient query processing across all parties is required. Traceability is emerging as one of the key applications of RFID technology. A generic data model is introduced for querying RFID data across a network of independently operated data sources. The model can be used to facilitate traceability query processing and give a set of representative traceability queries. A newly designed process-and-forward approach is implemented for executing traceability queries.

Abstract: Methods and apparatus, including computer program products, implementing and using techniques for managing security and privacy associations between an electronic product code value and an address of a repository containing information about an item represented by the electronic product code. A security certificate is issued to each of one or more parties that are authorized to use the repository. In response to a party among the one or more parties sensing the electronic product code, a record is created in the repository. The record represents the sensing of the electronic product code and includes a security certificate belonging to the party that sensed the electronic product code.
