5. Definitions
 A digital footprint is a trail left by interactions in a digital
environment; including the usage of TV, mobile phone,
internet and world wide web, mobile web and other devices
and sensors.
 Digital footprints provide data on what has been performed in
the digital environment; and are used in behavioral targeting,
personalization, targeted marketing, digital reputation, and
other social media or social graphing services.
 In social media, a digital footprint is the size of a person's
"online presence" measured by the number of individuals
with whom they interact. [Wikipedia, 25 Jan 2013]

6. A shorter definition
A person's “digital footprint” reflects how he
or she actively participates in the digital
universe, including use of the Internet and
social networks, e-mail, cell phones, digital
cameras and credit cards.

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?
 When you do a simple post, how many people can spread it /
read it ?
 Our digital interactions are not only based in Internet…..
 Do you own a mobile device?
 Do you have a Via Verde ID?
 Do you have a credit card?
 Do you have cable TV?
 In how many data bases own information about you?

own name? Try it ….
47 % of American users have at leas once
searched on the Internet their own name.
Five years ago the number was only 22%.

18. Who profits with that?
 The collected data can be used by the several players, in order
to redirect marketing attacks in a one-to-one approach ….
