Most digital cameras export images in the JPEG file format. This
lossy compression scheme employs a quantization table that controls
the amount of compression achieved. Different cameras typically
employ different tables. A comparison of an image's quantization
scheme to a database of known cameras affords a simple technique for
confirming or denying an image's source. Similarly, comparison to a
database of photo-editing software can be used in a forensic setting
to determine if an image was edited after its original recording.
