<p>This will be a wide-ranging lecture covering databases, privacy, and “computer-aided investigation.” This talk will include numerous examples of investigative online resources and databases, and will include an in-depth demonstration of an actual online investigation done on a volunteer subject. Emphasis will be placed on discussing the “digital footprints” that we all leave in our daily lives, and how it is now possible for an investigator (or government agent) to determine a person’s likes and dislikes, religion, political beliefs, sexual orientation, habits, hobbies, friends, family, finances, health, and even the person’s actual physical whereabouts, solely by the use of online data and related activity. The final half hour of the talk will be devoted to Q&A.</p>
