SemanticLIFE is a project that stores all information an individual works with in a semantically enriched form. Ontologies are used to improve the search process and to express queries in the way humans think - e.g. "Find the draft I've been working on when traveling home from the conference in Chicago". When people cooperate on projects they obviously need to share information without spending time on entering keywords and thinking about who should be able to access which data; the issue is to correctly configure access controls so that only required information is shared with the appropriate people. Using a combination of the Chinese Wall and the Bell LaPadula model we show how access controls can be configured correctly with little effort by the users. [ABSTRACT FROM AUTHOR] |
