Nice presentation by the Army called “Geotags and Location-based Social Networking.”
It offers important information on the potential dangers of leaving on Global Positioning System (GPS) services on electronic devices (such as smartphones and cameras) and using location-based social networking services.
– “Geotagging is the process of adding geographical identification to photographs, videos, websites, and SMS messages. It is the equivalent of adding a 10-digit coordinate to everything you post on the Internet.”
– Location-based social networking applications focus on ‘checking-in’ at various locations to earn points, badges, discounts” and even become mayor for the day.
Exposing your location is not only dangerous if your in the military and engaged on an operation. But rather, for all of us, broadcasting location and patterns of movement can be detrimental to personal privacy and security.
As the geotagging safety presentation advises, consider when (and when not) to:
- Turn off the GPS on devices such as smartphones and cameras.
- Keep geocoded photos offline from the Internet (i.e. Flikr, Picasa, etc.)
- Avoid use of location-based social networking services (e.g. FourSquare, Facebook Places, Gowalla, SCVNGR, etc.)
Sharing information–including where you are, were and are going–with family, friends, and colleagues can be a healthy and fun interchange; but sharing that information with “the wrong” people can leave you exposed and sorry.
Think twice–think about your privacy and security.
