With the increasing importance of correctly handling
privacy-sensitive data, significant work has been put in expressing
and enforcing privacy policies. Less work has been done however on
process itself is considered privacy-sensitive. In this paper, we
present a formal definition of the mutually privacy-preserving
policy negotiation problem, i.e.~the problem of negotiating what
data will be revealed under what conditions, while no party learns
anything about the other parties' preferences other than the outcome
of the negotiation.
