Digital Photo Forensics
Neal Krawetz · 2015
Abstract The abundance of graphics applications has made it easy for anyone to modify digital pictures. However, modified pictures can cause problems for fields where altered photographs may give the wrong impression. Issues arise when altered images are used to convey misleading news, alter a product's performance in advertisements and scientific research, or are associated with identity theft or court proceedings. Forensic imaging provides algorithms, tools, and techniques for detecting image tampering. This chapter focuses on the problem space and some of the more common approaches to address problems in this field.
