Building a Responsibility Model using Modal Logic - Towards Accountability, Capability and Commitment Concepts

This paper aims at building a responsibility model based on the concepts of Accountability, Capability and Commitment. This model's objective is firstly to help organizations for verifying the organization structure and detecting policy problems and inconsistency and secondly to bring a conceptual framework to support them for defining their corporate, security and access control policies. Our work provides a preliminary review of the research performed in that field and proposes, based on the observations, an UML responsibility model and a definition for all its components. Thereafter, we suggest and explain a deontic logic formalization of the most significant concepts. To achieve that, our innovation stands in the adaptation of the Traditional Threefold Classification from the alethic logic to an adapted threefold classification that targets "Responsibility" and based upon which commitment is somewhat refined.
