Executive Summary

Off late rich service offer in the World Wide Web increasingly requires the disclosure of personal user data. Service providers' appetite for personal user data, however, is accompanied by growing privacy implications for Internet users. Addressing this rising threat, privacy-enhancing technologies aim at aiding users in protecting their personal data. Even though effective privacy laws facilitate users to edit and revoke already disclosed personal data, few PET solutions support users in exercising this right.

This paper introduces the Data Disclosure Log component within a user-centric privacy architecture. Built on a browser-based logging extension, the paper presents a visualization tool that displays past personal data disclosures from different perspectives.
