Geolocation Data for Tax Collection

From the Law of Data Security & Investigations blog:

Social media like Yfrog, Flickr, Twitter, Instapaper, Foursquare and innumerable others broadcast an astonishing trove of publicly-accessible geolocation data about users.

This data can be aggregated so an observer can track people who are, for example, using mobile devices to tweet, “check-in” and publish photo albums of their minute-to-minute lives. Some mobile apps broadcast geolocation data constantly, automatically. A program aptly named “Creepy” demonstrates how to aggregate geolocation data from multiple public sources. It can plot a social media enthusiast’s up-to-the minute movement on a Google map!
