7. Is this fresh new concern?
 A big amount of personal data is distributed among several
heterogeneous Databases … many people think about it!
1994: George Orwell publishes the book “1984”;
1997: Wim Wenders directs the movie “The End of Violence”;
2007: Mary Madden, Susannah Fox, Aaron Smith and Jessica
Vitak publishes the book “Digital Footprints”;
2009: Tony Fish publishes the book “My Digital Footprint”;
2013: NSA monitors people all over the world?
2014: Every month we find new vulnerabilities in mobile
phones…!

9. Our concerns
 In a daily bases, our life is full of interactions with the digital
world….
 How long do you use social networks in a normal day?

 Do you own a mobile device?
 Do you have a Via Verde ID?
 Do you have a credit card?
