Selective access for supply chain management in the cloud

Abstract

Abstract-Object-level tracking along supply chains, enabled by the low-cost and wide availability of Radio Frequency Identification (RFID) technology, permits companies to collect large amounts of data (e.g., time, location, handling) about the goods they produce. Combining the data collected by the different companies along a supply chain can provide considerable advantages to all of them. However, such a sharing sometimes needs to be selective. Indeed, companies may need to keep some information about their business operations secret. In this paper, we propose a solution that enables selective sharing of data collected along a supply chain. Our solution uses the services offered by cloud providers for sharing data among companies, and relies on selective encryption for enforcing access restrictions over such data.
