摘要: This article presents a survey of authorisation models and considers their ‘fitness-for-purpose’ in facilitating information sharing. Network-supported sharing is an important technical capability that underpins collaboration support dynamic unpredictable activities such as emergency response, national security, infrastructure protection, supply chain integration emerging business based on the concept ‘virtual organisation’.
