This deliverable presents the overall design and implementation effort for the tools described in WP4. The first tool is targeting both regular end-users and corporate end-users and is comprised of a webbrowser plug-in and a user configuration panel. This tool enables the users with two main functionalities: the detection of trackers and blocking them, as well as the detection and reverse engineering of targeted advertisements. The second tool is a cookie proxy that detects privacy violation of end-users (regular and corporate) and safeguards them against such violations. The
functionalities of all tools are described in more detail and how they fulfil user and industry-related requirements.
