This video is a presentation of the publication " Mass Surveillance - Part 1: Risks, Opportunities and Mitigation Strategies" written for the Scientific Foresight Unit (STOA) of the European Parliament's Research Services (EPRS). When using the internet, we are leaving digital traces, composed of metadata, which, when analysed can reveal who your family, friends and colleagues are, where you have been at a certain point in time, when you have communicated with whom, for how long and on which device. Credit card use, mobile phone location data and internet address can be combined to draw conclusion about you based on the websites you have visited. Intelligence, security, and law-enforcement agencies are intercepting metadata indiscriminately and on a massive scale. The fundamental civil rights and liberties on which democracy is built are threatened by mass surveillance, as individuals cannot consider themselves free anymore if they are being watched. If you want your privacy to be respected, you should be able to decide who can access your digital traces. The most effective way of evading surveillance is to encrypt your content and anonymise your connection data.
