It sounds like a futuristic sci-fi fantasy. But the future is here.
The pictures and videos that you can be with your smartphone and then online books reveal your location to anyone who looks at the photo. It's called geotagging.
What is Geotagging?
Geotagging is the process of adding geographic information to a photo, a video, a website or an RSS feed. This information reveals your exact latitude and longitude when the photo was taken. The encryption is often done using geo-coordinates and GPS or global positioning system data.
Is it accurate? Absolutely. The geotags can identify a location within feet from where the photo was taken.
Metadata: what it is and why you should give
The data in the pictures is that embedded metadata. Metadata is hidden information is not easily seen by the normal viewer.
But with some simple technology (available online), this information is easily caught and read. Online software can scan the photos and produce the embedded coordinates. Once the coordinates have been noted, the street of Google maps offer a convenient way to locate exact addresses and street views.
Not every phone connect the metadata in the photos and videos, but many do. The phone must have been a built-in GPS in order to add geotags photos.
Lawful use for Geotagging
This technoloty can be useful for some people. For example, law enforcement agencies that solving crimes or get help to those who need hang in there. Further, photographers find it helpful if they catalog and systematizing their work.
Dream of a criminal
But of geotagging dangers lurk everywhere.
The implications for safety are staggering. Many people don't think twice about snapping a picture of the kitchen table they have for sale and placing it on Craigslist. Or the expensive jewelry they are trying to sell. But if the camera that they used the tagging photos, a thief can learn the precise location of seller home and help themselves to the items. If the seller also the best times to be achieved by the phone, the thief has also displayed an idea of when the House is empty now.
Stalking is also a real danger when it comes to geotagging. Twitter photos, Facebook photos, and casual snapshots on blogs can display all the stalkers information about their victims-where they live, what their favorite restaurants, where they are shopping, etc. It's essentially as a digital track be analysed and followed. A quick scan with software and a comparison with the Strait of Google maps is all that it takes. The outcome? Address and street view.
Disabling
Some people don't mind their information becomes public. But others do. If you are among those who want their photos tagged with geographic coordinates, you can disable it.
The settings can be changed on any phone that this metadata is embedded. Why is it turned on in the first place? Perhaps when the phone is bought, the seller did not mention the function, or if they did, the consequences of having it activated were not immediately clear.
Some of the phones that have this feature are:
• iPhone
• Blackberry
• Palm
• Google Android
To disable this feature, navigate to settings, and then find an option that is something similar to ' location ', entitled "location services", or "GPS." With some phones have, this feature can be disabled if the multiple times is associated with different applications.
For additional information about how to disable geotagging on your phone, can Ben Jackson and Larry Pesce help. They provide detailed instructions on their website. Visit http://icanstalku.com/how.php
Protect yourself
Search for disabling the software. There are software programs available for download right to your iPhone that scans your outgoing data for geotags and delete it.
If you saved pictures on Flicker that you suspect may be embedded location data, you can delete a batch GPS. Choose the photos you want to edit, and then select the location menu ' change ' and ' delete ' geoprivacy card information.
Your friends place photos of you online? If so, be aware that their cameras and phones can be embed as well as information on the location.
Geotagging can be useful and life-saving technology. But in the wrong hands, it is dangerous. You can safely continue aware of her presence and by his in control of your own data.
