Current ePedigree creation and discovery services rely on a centralized framework, i.e., EPCglobal network. The centralized system has several restrictions to prevent it from being widely adopted. For example, it is un-scalable when ePedigree service requests are increased dramatically due to the item-level product tracking; it has little privacy protection since the product historical information can be easily derived from the Object Name Service (ONS) provided by the centralized EPCglobal network; it is cumbersome since the ePedigree information will be amplified in the local databases along with the product transportation stops; and so on. To overcome the above mentioned problems, we propose a distributed EPC Information Service (EPC-IS), which makes the ePedigree creation and discovery more robust, scaleable, and secure. Using our approach, the ePedigree historical records of a product is created and stored in the ePedigree creating parties' EPC-IS servers; in addition, each EPC-IS server maintains a look up table that stores the EPC-IS providers' one-hop up/down stream information. In this way, the ePedigree service creation and discovery are processed following a chain of processes with a distributed manner. The distributed ePedigree architecture and a set of EPC-IS service protocols are described in this paper.
