COMPOSING HETEROGENOUS ACCESS POLICIES BETWEEN ORGANIZATIONSMay 7th, 2003
One crucial aspect of information technology for e-Society is security, where authorization is one of the three important factors, besides availability and integrity.

In this approach called Modular Authorization, we were able to provide techniques for a decentralized definition of access policies, which are inherited along the organizational structure.
