And people wonder why I don't belong to any of the social media and I don't use my cell to photograph. Of course being a bit of a nut for photography I usually have one of my cameras with me.

Its called Geo tagging and all you need to do is keep your gps turned off
Uh no, GPS doesn't have to be on for geo tagging to work. You have to turn off the setting in your camera or in your system settings. My gps is off by default and it still displayed the geo tagging info when I took pictures on my camera phone. This was from a Samsung Galaxy, the first version.

Cell Phone Camera Privacy Warning


Outline

Circulating message warns that cell phone photographs posted online contain information that can allow strangers to identify the location where the pictures were taken. The message contains a TV news video that discusses the issue.


Brief Analysis

The warning contains factual information that is worth heeding, but is nevertheless somewhat overblown. If GPS is enabled on the phone, geolocation data may indeed be included in the EXIF metadata that accompanies an image taken with the phone's camera. If the image is then uploaded to some websites, a viewer could use software to read the image's metadata and see the location where the photograph was taken. However, Facebook, Twitter and many other social networks now automatically remove metadata from images that are uploaded, thereby eliminating the potential problem on those networks. The news video in the message is several years old and is now quite outdated. Nevertheless, as a precaution, you can easily configure your phone so that GPS is disabled for your camera, thereby eliminating any potential risk.

Origins: Digital photographic devices (e.g., digital cameras, smartphones, scanners) typically use a standard known as Exchangeable image file format (Exif) that specifies how additional informational data may be stored with images as they are created. When you snap a picture with your digital camera, you may also (depending upon the type of camera and its settings) be capturing information about the date and time you took the photo, the camera type and the settings you used to take the picture, a description of the photograph, and copyright information. All of this information is stored as metadata in the same file that holds your photo.


One of the types of data that may be stored with images created by devices that use the Exif format is location information. Many mobile phones (and some digital cameras) now have built-in GPS receivers that can record precise information about where a picture was taken in the photograph's Exif header (commonly known as geotagging). When such photographs are shared with others (by posting them on the Internet, for example), it is possible that viewers can examine the Exif metadata stored with those images to find out information such as where the pictures were taken, and use tools that map the stored GPS information to specific locations (such as a particular house or school). This poses potential privacy and security issues, especially since some users may be completely unaware that their cameras are set up to store location information by default:




The storage of location based data, in the form of Latitude and Longitude inside of images is called Geotagging; essentially tagging your photograph with the geographic location. This data is stored inside if the metadata is JPEG images and is useful for tying the photograph to a location. Want to remember exactly where you took those photographs while on vacation? This information is for you.

However, most modern digital cameras do not automatically add geolocation (Latitude and Longitude) metadata to pictures. The process for adding the geolocation data either requires specialized add on hardware, or post processing with software on the desktop after the pictures are taken.

There is a large exception to this rule: Smartphones. With the proliferation of smart phones that contain GPS locator technology inside, the cameras in these devices are already equipped with the specialized hardware to automatically add geolocation information to the pictures at the time they are taken.

Most people don't realize that the action of automatic geotagging takes place on their smart phones, either because it is enabled by default, not exposed the user as an option, or was asked and then forgotten. As a result, individuals often share too much information about their location, right down to the exact Latitude and Longitude when snapping photos with their smartphone and posting them online.



However, this isn't really a "new" danger (the news video linked above is nearly four years old), and the potential for harm is much less now than it was when the story was originally reported. Where and how you post your photographs on the Internet makes a big difference: If you put up photographs on the Internet by directly copying them to your own web site, then geotagging might be an issue you need to take heed of. But if you use one or more of the currently popular photo-sharing and social media web sites (such as Facebook and Twitter), geotagging is not much of an issue because those sites now automatically strip some or all of the Exif metadata from uploaded pictures in order to protect user privacy. (Other sites may leave Exif metadata intact or provide users with the option of whether or not to make the Exif information from their uploaded photos available to other viewers.)


Picture-takers have a number of ways of avoiding storing location information with their photographs or eliminating it from existing pictures. Turning off your device's GPS feature is the most straightforward way: if your camera or smartphone can't use GPS to determine where you are when you take a picture, it can't store that information with your photo. After the fact, you can use an Exif metadata editor to remove or change information stored with your photographs, or you can use a photo editor or converter program to save your photographs in a format that does not support Exif metadata.
