The integration between access control and version control emerges as a new technique in security for a recent year. This thesis introduces a framework that enhances access control in the digital repository system by integrating access control and version control with time constraint. Even though previous access control researches mostly use subject attributes and resources attributes for a decision making, in this framework, only resource attributes and time constraint are used for requesting document construction. The access control policy document is created by analyzing a changed content in each version of protected documents. Moreover, the dependency of access control policy document and XML versioned relevancy-based access control are also introduced UR - http://203.159.5.9/ait-thesis/detail.php?q=B09506 ER -
