Smartphones and digital cameras use a standard to specify formats for images and sounds that are recorded using them. This standard is called the exchangeable image file format (EXIF). Various EXIF data viewers are available. They provide details such as type of camera, focal length, type of lens, and so on. Most importantly, EXIF data viewers provide the geo location information that is stored for each image. In fact, by default, all smartphones have the GPS setting switched on. So, this can potentially leak the location where the image was taken. The accuracy is such that the latitude and longitude will be provided by the EXIF data viewer when extracting the EXIF data, thus leaking very private information.
