This document discusses digital footprints and how technology collects information about individuals. It defines a digital footprint as the trail of data left behind by a person's interactions online and through various technologies. Examples discussed include information collected from social media use, mobile phones, credit cards, location services, and other devices. The document also notes scenarios where digital footprints are collected through technologies like mobile phones, wireless networks, cable TV systems, ATMs, and traffic cameras. It addresses concerns about how much personal data is out there and how it is used, and provides some tips for minimizing privacy risks online.

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…!

8. Conspiracy Theory ???
No ! Minimum knowledge will help me to
build the digital footprint that fits me ….

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?

10. Applications
CRM - Customer Relationship Management
 Help companies to fit there offer to each client profile
Facebook
 Adjusts the best adds in your FB profile
Youtube
 Suggest the videos that you “perhaps” like more

12. How is the association of a single
phone and its user?
Mobile ID – IMEI;
SIM.

13. Where is my phone?
Is for sure near to a Communication
Tower (outdoor/indoor antenna);
Is my GPS on?
I am using any Location Based
Application ?

14. Surfing the WEB
ISP controls the Internet Access:
Adjusts the traffic speed;
Allocates an IP address:
IP address can be traced to:
Find geographic position of the user…!
How? Check: http://www.iplocation.net/

16. Ordinary daily scenario
After waking up, i start zapping on my cable TV;
While eating my breakfast - I surf on my tablet;
I am going to work, while my car (in the

17. Any of you have “googled” your
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%.
17

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 ….

19. How do we handle our personal
problem?
 Personal data spread in a non homogeneous form;
 Worldwide replication;
 Complex to be quantified;
 Dynamically changing.
Some companies already earn money in Googlewashing…!
