Data access control for energy-related services in smart public infrastructures

In smart urban infrastructures, access control technology is needed to provide appropriate consumer data to appropriate service providers. In this paper, we analyse the characteristics of and problems with data access in the service platform for smart city public infrastructures to clarify requirements for data access control. Then, we propose a data access control method that satisfies these requirements. The data access control method encompasses a data model for access authorization information that reflects the contracts between consumers and service providers. We develop a prototype system that implements the proposed access control method and experimentally show that the proposed method satisfies performance requirement using the prototype system.
