Ontology Security Strategy of Security Data Integrity

There exists a variety of heterogeneous data that need to be integrated within a secure domain. How to integrate the security data from various data source safely is a challenge for database researchers. In this paper, we introduce a new model for security data integrity, Weight-value-Extended MLS (WEMLS), which is development based on MLS. Compared with MLS, WEMLS can not only guarantee the security and integrity of data accessing, but also provide a more flexible mechanism for data accessing. Finally, WEMLS has been verified by proposing a security data integration model based on ontology.
