Abstract

Several models of authorization for object-oriented databases, supporting different levels of granularity, have been proposed. However, these models do not support authorization based on database content and context. A way of handling context and content-dependent authorization is by using views. In this paper, we present a model of authorization that supports content-based access control on instances of a class.
