ABSTRACT:
Authorization control has been studied for years, and there are quite a few theory and techniques available for handling access control for a single or centralized system.

However unique and challenging security issues concerning business collaboration in the context of service oriented computing (SOC) have arisen due to the dynamic and loosely coupling nature of the environment in which the business collaboration is normally conducted.

Different types of business collaboration exist in terms of the way that the collaboration iscarried out. We are currently working on these differnces. We look into the characteristics of different collaborations and analyze their policy requirements accordingly.

Various inconsistencies between authorization policies from different business units are identified and suggestions are made according to different types collaboration. We believe our work is laying a foundation for secure cross-organization collaborations.
