Disabling GPS Tracking of Your Whereabouts

Geotags make it very easy for friends, relatives, bosses, spouses, parents, enemies, law enforcement, stalkers and thieves to know exactly where you are.

With the increased use of Internet-enabled mobile devices such as the Blackberry, Droid and iPhone, geotagging has seen a huge increase in popularity. When social media users take a picture or video and upload it to their page, they are probably transmitting far more data than they think. With the ability to quickly add GPS information to media, smartphones make geotagging a simple task.

So What is Geotagging?

Simply, geotagging is where location or geographical information, such as your GPS coordinates, are added and embedded to different types of media (.jpg, .mov files, etc.). Invisible to the naked eye and the casual observer, geotags are part of the meta-data, or underlying data about the data, that accompanies each file. Examples of meta-data include when the file was created or modified, by whom, using what device and software. This data is often loaded on to your computer along with the original file. Browser plug-ins and certain software programs can reveal the location information to anyone who wants to see it.

Twittervision makes great use of geotagging. Twittervision is a web mashup combining Twitter with Google Maps to create a real time display of tweets across a map. It also has a 3D mode that displays a globe of the Earth which spins to pinpoint arriving messages from Twitter.

So, who would want to know where you are?>BR>
While most of the uses are not fully apparent yet, your real-time location can reveal your home address, work address, places you visit often and at what time of day. It can reveal if you go to the doctor, a lawyer, a court date, or any other type of private meeting. Geotags make it very easy for friends, relatives, bosses, spouses, parents, enemies, law enforcement, stalkers, and thieves to know exactly where you are.

Telling everyone on your Facebook status that you are out for the evening can invite burglars; geotagging can do the same without you updating your status in any way. By taking a picture at the Barry Manilow concert and uploading it to your twitter account, you are broadcasting the fact that you are probably over 40, away from home and, thanks to the geotag, exactly how far away you are.

If you've never seen Minority Report with Tom Cruise (where ads are served up to you on giant screens based on biometrics and your current location as you walk through the city ), it's worth your time. Of course the movie exaggerates reality, that is one of the hallmarks of science fiction. But it does so in order to make you think about the possibilities and future realities. And that is exactly what corporations are doing. Using geotags that you upload into social networks (photos, videos, check-ins), they can see that you enjoy Starbucks and live in a certain neighborhood, so they may purchase a billboard in the area or more likely, target an ad to you on your Facebook wall. Although this can seem harmless, it will eventually raise larger concerns on consumer privacy.

In this fast paced electronic world, more and more people are using smartphones and therefore we can expect an increased use of geotags in the future. The problem with geotagging is that since it is not visible to the naked eye, most people don't even realize they are sharing their location data. So what if you don't want to transmit your location data?

Keeping location data private can be difficult, but here are some places to start:

-- Understand that anytime you take a picture, video or post an update from a networked device (somehow connected to the internet), your location is probably being appended to the file, even though it is hidden from you. As with all things technological, there are advantages and disadvantages to all features. Location based services also allow you to use ha
