Most of today's smartphones with cameras, as well as scanners, compact digital cameras and SLR cameras, have the ability to incorporate information such as the geographic location in which they were taken, the date, the camera model, sometimes even the serial number, the author of the photo and numerous other traceable attributes.
This information is stored in the EXIF metadata.
