Abstract. This paper investigates how to restrict the spread of sensitive informa-tion. This work is situated in a military context, and provides a tractable method to decide what semantic information to share, with whom, and how. The latter de-cision is supported by obfuscation, where a related concept or fact may be shared instead of the original. We consider uncertain information, and utilize Subjective Logic as an underlying formalism to further obfuscate concepts, and reason about obfuscated concepts.
