This document provides an overview and agenda for a tutorial on extracting intelligence from digital traces and trails left by web and mobile users. It discusses the proliferation of digital devices that create extensive data about people's online and mobile activities. Examples are given of different types of digital traces, including cookies, web bugs, location data, and social media interactions. Concerns about privacy are also mentioned as vast amounts of personal data are now collected and analyzed.

12. Lifelogging: MyLifeBits – Gordon Bell “ I’m losing my mind… By the way so are you.” “ Soon… you will have the capacity for Total Recall. You will be able to summon up everything you have ever see, heard, or done And you will be in total control, able to retrieve as much or as little as you want at any given time.”

13. Total Recall: Reminiscent of the Memex “ A memex is a device in which an individual stores all his books, records, and communications, and which is mechanized so that it may be consulted with exceeding speed and flexibility.” Vannevar Bush (1945)

20. 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]

33. 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 "interact" with it (commenting or offering improvements) and the other 89 will just view it.

35. 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?
