Privacy is not about hiding things that we want to keep secret. It is about our right to choose, when, for what purpose and who can see certain data about us. It’s about control. Even data that might seem meaningless, like separate internet application logs or IP address that changes apparently with every new session, but put together they might reveal a lot about Internet user with surprising accuracy. We might lose track of what we have put online, but Internet doesn’t forget. It may even guess things that you never told anybody. Unfortunately usage of digital shadow, especially for profiling purposes, is not regulated by law. What can you do to reduce your digital shadow or stop others form using it against you?

Since the first stories revealing the extent of mass surveillance appeared in the Guardian in June 2013, the Snowden files have helped to shine a light on the government agencies who monitor the online activity of their citizens and the companies who collect their customers’ personal data. Julia Powles (University of Cambridge), Mike Harris (Don’t Spy On Us), Josh Levy (Access Now) and Katarzyna Szymielewicz (Panoptykon Foundation) in a panel chaired by James Ball (The Guardian) explore who owns our data, how to take control of our online lives and ask what is the future of our personal data.

Our data shadows and digital dandruff can be used to track and record our activities online. Even if there is nothing to hide, this can become problematic. Katarzyna Szymielewicz discuss these problems with Jeremy Malcolm (Electronic Frontiers Foundation), Joana Varon (Centre for Technology and Society in Rio de Janeiro), Niels ten Oever (Article 19) and Harry Halpin (World Wide Web Consortium - W3C).

Panoptykon presents four short animated movies about family life "under surveillance". Series intend is to show how surveillance affects all of us: how use of modern tools such us cameras, ID cards, databases, scripts, and ad tracking tools - control all spheres of our lives.

"All indications are that the attack on the editorial offices of satirical magazine Charlie Hebdo will provide a pretext for the introduction of further limits on our civil liberties - a new order the victims of which are unlikely to be terrorists … Independent analyses confirm that data inflation and the growing use of algorithms in intelligence work do not improve the effectiveness of threat detection.
