Failure Feedback for User Obligation Systems
In recent years, several researchers have proposed techniques for providing users with assistance in understanding and overcoming authorization denials. The incorporation of environmental factors into authorization decisions has made this particularly important and challenging. An environmental factor that has not previously been considered in this effort to provide such assistance to users arises in systems where obligations can depend on and affect authorizations.
