Abstract

The interoperability among different data formats over the Internet has drawn increasing interest recently due to more and more heterogeneous data models are used in different Web services. In order to ease the manipulation of data models for heterogeneous data, generic model management has been intensively researched and also implemented in a prototype since its first introduction. Access control specifications attached to each individual data model require significant amount of efforts to manually specify. Based on a general security model for access control specifications on heterogeneous data models and its visual representation, we present secure model management operators for managing access control specifications.The secure model management operators disccussed in the paper include a secure match operator and a secure merge operator. We introduce a novel graphical schema matching algorithm and extend the algorithm to make a secure match operator. The paper also discusses secure merge principles for the integration of data models.
