Abstract: In this paper, the construction of role-based access control model is discussed. Aiming at the complexity of the subjects, combined with the particularity of actions and objects in document management, considering the restriction of subject and the state of object, some improvement is made in the original RBAC model and a new team-role-based document access control model which is named "TRBDAC model" is presented. ;
