Information leakage is a growing public concern. This paper describes a visualization system for tracing leaks involving confidential information. In particular, the system enables administrators to determine which hosts have confidential documents and the means by which confidential information is transmitted, received and duplicated. The visualization system is scalable to large organizations...

In the context of multi-agent hypothetical reasoning, agents typically have partial knowledge about their environments, and the union of such knowledge is still incomplete to represent the whole world. Thus, given a global query they collaborate with each other to make correct inferences and hypothesis, whilst maintaining global constraints. Most collaborative reasoning systems operate on the a...

Information flow security in a multilevel system aims at guaranteeing that no high level information is revealed to low level users, even in the presence of any possible malicious process. This requirement could be too demanding when some knowledge about the environment (context) in which the process is going to run is available. To deal with these situations we introduce the notion of secure c...

Responses of a small sample (N = 67) of former drug treatment clients interviewed using procedures exactly modeled on the National Household Survey on Drug Abuse were compared to their clinic records. The accuracy of reports compared to clinic records varied by drug, wi...
