Classification and Recovery of Fragmented Multimedia Files using the File Carving Approach

File carving is a recovery technique which does not consider file tables or other meta-data which is used to organize data on storage media. As files can be recovered based only on their content and/or structure, this technique is an indispensable task during digital investigations. The main contribution of this paper is the description of procedures that allow for successful content-based recovery of multimedia files from their fragments. So far many approaches for the recovery of digital images have been proposed. After a short discussion of relevant representatives in this domain the authors focus on the applicability of these approaches to the recovery of multimedia files.
