Secure information sharing in digital supply chains

Modern organizations interact with their partners through digital supply chain business processes for producing and delivering products and services to consumers. A partner in this supply chain can be a sub-contractor to whom work is outsourced. Each partner in a supply chain uses data, generates data and shares data with other partners, and all this collaboration contributes to producing and delivering the product(s) or service(s). The main security challenge in supply chains is the unauthorized disclosure and data leakage of information shared among the partners. Current approaches for protecting data in supply chain rely on the use of standards, service level agreements, and legal contracts. We propose an auditing based approach for protecting shared data in digital supply chains
