New Advances on Privacy-Preserving Policy Reconciliation

Ulrike Meyer, Susanne Wetzel, and Sotiris Ioannidis


Entities define their own set of rules under which they are willing to collaborate, e.g., interact, share and exchange resources or information with others. Typically, these individual policies differ for different parties. Thus, collaboration requires the resolving of differences and reaching a consensus. This process is generally referred to as policy reconciliation. Current solutions for policy reconciliation do not take into account the privacy concerns of reconciliating parties. This paper addresses the problem of preserving privacy during policy reconciliation. We introduce new protocols that meet the privacy requirements of the organizations and allow parties to find a common policy rule which optimizes their individual preferences.
