Abstract:The access control policy defines the rights and privileges for different users on database objects. In order to maintain the security of these database systems, the database security should be controlled to protect the contents of the access database, as well as to preserve the integrity and consistency of the data. In order to achieve consistent database access control strategy, in this paper, we propose a temporal reflection database access control (TRDBAC), a new access control strategy, aiming to eliminate the limitations of RDBAC. To express the time limit our new strategy has demonstrated the results of a case study on a student information system, where strategies are written in the reflective database access control (RDBAC) for extended time based. Finally, we analyze the behavior of the new model.
