discuss a formal model that decides a comparable trade-off for releasing both data
and their associated provenance while hiding provenance in the case of intoler-
able losses. In Chapter 19 we discuss some novel approaches for inference control
including game theoretic models amd mathematical programming techniques.
All of our security mechanisms explored so far for provenance suffer from what
is known as an inference attack. at is, a user may employ different inference strat-
egies in order to arrive at new information ...
