6.
Proliferation of Traces & Trails <ul><li>Our lives have been leaving increasingly complete and detailed traces in cyberspace as two-way electronic communications devices have proliferated and diversified. Telephones were the first such devices to find widespread use; they soon yielded telephone billing data – records of when, where and by whom calls were made. Then bank ATM machines and point-of-sale terminals began to produce transaction records. As personal computer were plugged into commercial online networks, they too began to create electronic trails… There is more of this to come. As switched video networks become extensively used for everyday purposes – shopping, banking, selecting movies, social contact, political assembly – they potentially will grab and keep much more detailed portraits of private lives than have ever been made before. And wearable devices – ones that continuously monitor your medical condition, for example, or perhaps a cybersex suit that some journalists have avidly imagined – may construct the most up-close and intimate records. </li></ul>

7.
Where there's data … <ul><li>Data mining technologies are pervasive in our society. The are designed to capture, aggregate, and analyze our digital footprints, such as purchases, Internet search strings, blogs, and travel patterns in an attempt to profile individuals for a variety of applications (Jason Millar, Problem for Predictive Data Mining, Lessons from Identity Trail, 2009) </li></ul>

8.
Digital Trails: Their Value & Misuse <ul><li>The value of this data is unprecedented in the history of mankind. If you consider the sum of your online searching, mapping, communicating, blogging, news reading, shopping, and browsing, you should realize that you've revealed a very complete picture of yourself and placed it on the servers of a select few online companies. </li></ul><ul><li>The thin veneer of anonymity on the web is insufficient to protect you from revealing your identity. If you aren't even a little concerned, you should be. The value of this information is staggering and ripe for misuse. </li></ul>

9.
Digital Traces and/or Trails: Informal Definitions <ul><li>Digital traces refer to the traces of activities and behaviors that people leave when they interact in digital environments (en.wikipedia.org/wiki/Digital_traces). </li></ul><ul><li>Digital trails refer to the associations or interconnections of these traces with other traces and with other sources of information </li></ul>

Digital Traces: How much is a free smartphone worth? In the fall of 2008, 100 undergraduate students living in Random Hall at M.I.T. agreed for one year to swap their privacy for free smartphones in exchange for participating in a n MIT study aimed at understanding the impact of social interaction on social diffusion. When the participating students dialed other students, sent e-mails, or listened to songs the researchers knew…Every moment the students had their Windows Mobile smartphones with them, the researchers knew where they were and who was nearby. [ Translated into 350,000 hours of data – e.g. 65,000 phone calls, 25,000 SMS messages, 3.3 million scanned bluetooth devices and 2.5 million scanned 802.11 WLAN APs]

1% Rule (or something like that) 434 It's an emerging rule of thumb that suggests that if you get a group of 100 people online then one will create content, 10 will &quot;interact&quot; with it (commenting or offering improvements) and the other 89 will just view it.

34.
The Evidence of the 1% Rule <ul><li>YouTube -- each day there are 100 million downloads and 65,000 uploads - which is 1,538 downloads per upload - and 20m unique users per month. </li></ul><ul><ul><li>That puts the &quot;creator to consumer&quot; ratio at just 0.5%, but it's early days yet; not everyone has discovered YouTube (and it does make downloading much easier than uploading, because any web page can host a YouTube link). </li></ul></ul><ul><li>Wikipedia -- 50% of all article edits are done by 0.7% of users, and more than 70% of all articles have been written by just 1.8% of all users. </li></ul><ul><li>Yahoo Groups discussion lists -- &quot;1% of the user population might start a group; 10% of the user population might participate actively, and actually author content, whether starting a thread or responding to a thread-in-progress; 100% of the user population benefits from the activities of the above groups,&quot; he noted on his blog ( www.elatable.com/blog/?p=5 ) in February. </li></ul>

Day in the life … Recording without even trying http://newsinitiative.org/story/2006/08/15/digital_trails We log onto computers at school and work, use our debit cards to buy lunch, scan our membership cards at the gym; the list goes on and on. With each of these everyday acts we leave a digital bread crumb that enables others to track our movements. But how often do we stop and wonder, who is following these virtual trails?
