My friend just bought a new phone, and despite all the recommendations a few of us have given him, he went and bought an iPhone :facepalm: As well as it being a total waste of perfectly good money, the iPhone has a feature enabled which also broadcasts your location to everybody in the whole world who has an internet connection. Geo-tagging.
Why anyone would want to have this turned on is completely beyond my belief, but the scary thing is - it's enabled by default. Worried yet? Well, if you're an iPhone owner then you probably should be, especially if you share your photos on the internet via social networking sites, or even upload them to Photobucket or Imageshack.
Geo-tagging allows your iPhone to access it's GPS system, pinpoint your location at the time you took your photograph, and write that information to the EXIF data stored in the image. If you don't know what EXIF data
is, then I suggest clicking that link and reading the Wikipedia page on it. The information is stored inside the image, and if you don't remove it before uploading it to the internet... Well, that's how people are able to see exactly where you are and where you've been.
So, if you own an iPhone and are conscious about your privacy then you should seriously consider disabling this terrible feature!
