Controlled Query Evaluation in General Semantics with Inc...
Werner, Johannes Martin
Inauguraldissertation an der Philosophisch-naturwissenschaftlichen Fakultät der Universität Bern.
The thesis describes possible mechanisms that allow manipulations of query-sequences in order to hide secret information from a potentially malicious query-agent.
This is investigated in a strictly formal way: The surrounding information framework is reduced to general semantics and allows modelling of incomplete information.
