Recycling Authorizations: Toward Secondary and Approximate Authorizations Model (SAAM)

In large and complex enterprises, obtaining authorizations could be communicationally and/or computationally expensive, and, due to infrastructure failures, some times even impossible. This paper establishes the concept of recycling previously made authorizations for serving new authorization requests. It introduces secondary and approximate authorizations model (SAAM) with the semantics of matching best suitable approximate authorizations.
