Trust framework for RFID tracking in supply chain management

RFID tracking systems are in an open system environment, where different organizations have different business workflows and operate on different standards and protocols. RFID tracking to be effective, it is imperative for RFID tracking systems to trust each other and be collaborative. However, RFID tracking systems operating in the open system environment are constantly evolving and hence, the related trust and the collaborations need to be dynamic to changes. This paper presents a seven-layer RFID trust framework to promote the resolution of merging with both social and technology traits in enhancing security, privacy and integrity of global RFID tracking systems. An example of integration of our trust framework with supply-chain management applications and trust evaluation is also presented
