Geotagging helps add a location to your digital photographs, video, websites or even news feeds. In devices like iPhones and other smartphones, additional information is automatically captured, such as longitude and latitude of where the image was taken.
Using particular tools and programs, a person determined to find out this type of information can decipher any geotagged image and retrieve the information for their own purposes. For example, sharing a photo taken at your house, may advertise the address of your house.
Most smartphones have the geotagging feature automatically enabled, so you need to put in the effort to prevent it from doing this.
It’s recommended that you disable the geotagging ability and enable it again when you make a conscious decision to use it; it’s far better to opt in than to try to remember to opt out.
