Secure access wrapper: mediating security between heterogeneous databases

Organizations today are faced with an ever-increasing need to become more efficient in their methods for exchange of information with consumers, collaborators, and partners. Unfortunately existing mechanisms for such information exchange provide nowhere near the levels of both security and automation required to satisfy this need. Effective information sharing and dissemination can take place only if the data holders have assurance that access constraints on the information they own or manage will be respected and that, while releasing information, disclosure of sensitive information is not a risk. The Secure Access Wrapper (SAW) project is a collaborative effort between SRI International and Stanford University to develop techniques that provide substantially more automation and assurance than has previously been available for secure, selective information sharing. The SAW project is sponsored by DARPA ITO under the Wrappers and Composition focus area of the Information Survivability program.
