EXECUTIVE SUMMARY
This deliverable describes the design and implementation of four privacy violation detection tools for end users and regulators alike. These include browser add-ons for detecting the
presence of trackers and for reverse engineering the online advertisement placement, a web-based auditing tool for testing whether specific web-sites and the advertisers/data aggregators
working with them are collecting/processing sensitive personal data of users, and a crowdsourced database for building a corpus of data for further privacy analyses by independent investigators or automated tools.
