Abstract
A fragmented JPEG image is currently not possible to reassemble without knowing the ordering of the fragments. This is a problem for the police when they search for illegal digital images. This paper presents a method to reassemble fragmented JPEG images containing restart markers. Empirical evaluations show that it is possible to reassemble images taken from a set containing fragments of several images.
