Privacy-preserving Verifiable Data Audits
The main aim of this project was to build a prototype system that adds transparency to the way different parties interact with sensitive data by maintaining Verifiable Privacy Audit Logs. The system records a log containing timestamped information of the participants involved in the privacy-sensitive data processing event in a verifiable (append-only, tamper-proof) data structure every time such an interaction takes place. Verifiable Data Structures recently exploited for projects such as Certificate, Key or General Transparency were investigated for the purpose of building such a system.
