Publishing L2TAP Logs to Facilitate Transparency and Accountability

We propose publishing L2TAP privacy logs to facilitate pri-vacy auditing tasks that involve multiple auditors, an increas-ingly common requirement in the context of social computing and big data driven science. Our proposal utilizes two on-tologies, L2TAP and SCIP, designed for deployment in a Linked Data environment. L2TAP provides provenance en-abled logging of events. SCIP synthesizes contextual integrity concepts to express key privacy-related semantics associated with log events. We describe SPARQL query-based solu-tions for privacy log construction, obligation derivation, and compliance checking. The solutions facilitate accountability and transparency among participants (privacy auditors in particular). 1
