This was in today's ACM Tech News. I haven't read the aarticle yet, but it looks like it may be of interest:
Penn State researchers presented the paper "Privacy-preserving Semantic Interoperation and Access Control of Heterogeneous Databases" at the recent ACM Symposium on Information, Communication and Computer Security in Taiwan. In the paper, the researchers describe the development of new software that allows databases to communicate with each other without jeopardizing the security of their data and metadata. The Privacy-preserving Access Control Toolkit (PACT) is designed to act in the manner of a filter by encrypting queries, data communicated, and other information. "The software automatically regulates access to data, so some information can be exchanged while other data remains confidential and private," explained Prasenjit Mitra, assistant professor of information sciences and technology at Penn State. "Often when we implement security, we decide not to give access to data." The researchers took a more generic approach to designing PACT compared with the special-purpose applications that organizations develop for sharing data, which are expensive, take more time to develop, and do not address security issues. Research on PACT will continue with the development of a new rule language to enhance interoperability as well as improvements to boost the performance of query processing.
