Abstract

When we write access-control description of the Web Applications using the group and the role, there is a problem that it is difficult for a user to decide the joint ownership partner of data. Therefore, there are the trials for describing access-control using social networks. However, unexpected defects might sneak in this description if it is marked in a careless manner. In this paper, we propose the formal definition of the access-control description consist of the first-order predicate logic for the automatic checking.
