Compatibility Checking Between Privacy and Utility Policies: A Query-Based Approach

Résumé

Data sharing over the internet through smart devices is susceptible to disclose sensitive information of data producers. To protect the privacy of data producers, we propose a querybased approach where data producers keep their data on decentralized personal data servers and only disclose data to data consumers over secure communication links according to their privacy policies. Data consumers specify the data needed to provide services as utility policies. In our approach, we express the privacy and utility policies as sets of temporal aggregated conjunctive queries. We make explicit several sufficient conditions of compatibility between privacy and utility policies based on their query expressions. On the basis of these results, sensitive data breaches can be prevented by checking whether one of these sufficient conditions is satisfied.
