Roadmap to Approaches for Carving of Fragmented Multimedia Files

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 a survey about new approaches in the file carving research field and a roadmap that outlines the necessary steps towards video file carving. So far many approaches for the recovery of digital images have been proposed. After a short discussion of relevant representatives in this domain we focus on the applicability of these approaches to the recovery of multimedia files. Further this paper discusses ideas from the forensics wiki for their applicability to such a file carver. Finally our findings are summarized verbally and visually as a roadmap.
