What is JPEG

Chapter 5
Handbook of Research on Computational Forensics, Digital Crime, and Investigation: Methods and Solutions
A compressed format for digital still photographs, referencing the Joint Photographic Experts Group (JPEG) who originated the standard. Actually includes several formats within a common framework. JPEG’s Sequential Mode format is lossy (permanently discards information) and ubiquitously supported by digital still cameras and image processing software.

Digital Camera Photographic Provenance

Abstract
Whether investigating individual photographs or a large repository of images, it is often critical to establish some history of the generation, manipulation and/or distribution of the images, which is to say the provenance. The applications of image provenance are wide, including the detection of steganographic messages and image tampering, the clustering of images with like provenance, and the gathering of evidence which establishes (or refutes) a hypothetical source. This chapter considers published research and identifies research gaps which address the general challenges of digital image provenance with an explicit emphasis on evidence related to the camera or other digital source.

Web Map Servers Data Formats
Joint Photograph Group. Standard image format created to store photograph as a compressed rectangular array of pixels. The compressed images usually have lower quality compared to the originals but, for some compression ratios this is not noticeable by a human eye.
