Enhancing Privacy Using Crowdsourcing Mechanisms.

Personal data have become a merchandisable asset encouraging various stakeholders to collect data and trade them without the end-useru0027s awareness and acceptance. Privacy Flag combines crowd sourcing, ICT technology and legal expertise in order to enable citizens to monitor and control their privacy with a user friendly solution provided as a smart phone application and a web browser add-on. In this paper, firstly, we focus on collective protection frameworks and tools that intend to address the arising challenges with respect to citizen awareness over data protection. Then, we present the Universal Privacy Risk Area Assessment Methodology, as well as the main functionalities of two Privacy Flag tools we developed; the browser add-on and the smartphone application.1
