Composite Access Control Model for RFID Information in Supply Chain
Youlun Xiong · 2008
The dynamic,crossover,versatility and complex relation among entities in a supply chain brings great challenges for the access control of RFID data and related information.Based on the analysis of relation between entities,user and entities,a composite access control model for the RFID data and related information in digital supply chain was presented,which combines some of the existed access models.An authorization specification for information access was designed,the map between user and information access authorization is established,and the workflow to decide whether a use can access some information is given.An implementation for such composite access control model is given based on relational database and workflow engine.
