Abstract :
Hiding is an important characteristic of the object-oriented paradigm. The author shows how hiding can be exploited to support data security and privacy. The model is based on a single type of authorization, that is, the authorization of a user to execute a method on a given object. The rationale of the authorization model is described. A formal definition of the model is presented, and the algorithms for the main authorization functions, such as grant and revoke, are described
