Privacy-preserving Data Sharing for Secure Economic Utility: A Game-Theoretic Approach

For the future economy -- and particularly for the banking, finance and regulatory sectors – data information utility provides a vital form of economic utility (the ability of the service and good to satisfy a customer's needs). A key means to capturing, and improving, data information utility is the detailed sharing of consumer information amongst different entities, such as different banks and prudential organisations. However, the sharing of such consumer data must preserve each consumer’s rights to privacy --- as a legally-mandated, commercial and ethical imperative, which also protects commercial confidentiality for relevant financial institutions. Thus, there is a clear barrier to unlocking the significant gains from economic utility that could otherwise be achieved by data sharing, in such a need for secure economic utility. This project will provide the methodology to directly remove such a barrier to data sharing, and, moreover do this in an optimal manner – as the best, and viable, balance between data information utility and consumer privacy preservation – by a game theoretic approach.
