Summary:

Users have the right to consent to the use of their data, but current methods are limited to very coarse-grained expressions of consent, as “opt-in/opt-out” choices for certain uses. In this episode, George talks about how he and his group identified the need for fine-grained consent management and how they formalized how to express and manage user consent and personal contracts of data usage in relational databases. Their approach enables data owners to express the intended data usage in formal specifications, called consent constraints, and enables a service provider that wants to honor these constraints, to automatically do so by filtering query results that violate consent; rather than both sides relying on “terms of use” agreements written in natural language. He talks about the implementation of their framework in an open source RDBMS, and the evaluation against the most relevant privacy approach using the TPC-H benchmark and a real dataset of ICU data.
