Abstract

Mediation techniques support integrated query processing among heterogeneous  databases.  While such techniques help data sharing among different distributed sources,   they increase the risk for data security, such as violating access control rule. Successful protection of information by an effective  access  control  mechanism is    a  basic requirement for data integration among  heterogeneous sources. How to protect the object  with fine-granularity, how to support the  access  control  specification at   different points,  and  how to support the semantic heterogeneity in the access control become the major challenges in the data protection of  the  mediation system. Currently few existing  approaches address all three security challenges inmediation system. With the purpose of solving  the aforementioned  challenges faced by the access  control in  mediation system, we present an architectural   and practical solution to assure the data security in the process of data integration from different sources.
