Integration of Access Control in Information Systems: From Role Engineering to Implementation
Résumé
Pervasive computing and proliferation of smart gadgets lead organizations to open their information systems,
especially by extensive use of mobile technology: information systems must be available any-time,
any-where, on any media. This cannot be done reasonably without thorough access control policies. Such
access control must be able to deal with user profile, time and even with more complex contexts including
geographical position. This paper shows that it is possible to take into account confidentiality constraints
straight into the logical data model in a homogeneous way, for various aspects generally treated independently
(user profile, time, geographical position, etc.). We propose a language called RAPOOL which
allows the expression of authorizations at the class level. We first present the syntactical aspects, then the
semantics of the language, based on the object-oriented paradigm.
