Building a Data Trust: Fine(r)-Grained Attribute Based Policy Machine

With the increase in data sharing and a growing number of data consumers, access control can become a challenging task to manage. This paper introduces the development of the Finer-Grained Attribute-based Policy (FiGAP) machine, an innovative framework designed to manage access within a Data Trust. FiGAP leverages fine-grained access control mechanisms with inheritance to facilitate enhanced data sharing across different organizational boundaries. Unlike other access control models, this paper develops and thoroughly explains a distinct framework that allows for the establishment of an adaptable Data Trust, potentially as a service. Additionally, this approach also provides an exceptionally detailed level of permission control.
