Access control for cooperative systems: A comparative analysis

Abstract

Collaboration allows sharing, processing and exchanging large amounts of data between individuals as well as groups and organizations. In this context, security and access control are important issues that should be studied, specified and enforced. In this paper, we discuss the different approaches that address access control for cooperative systems while putting emphasis on some important proposals; we conclude with a comparison between some interesting approaches, and we introduce some perspectives that help developing the domain.
