Advanced File Carving Approaches for Multimedia Files
File carving is a recovery technique that recovers files based on information about their structure and content without matching file system information. As files can be recovered from their content and/or file structure this technique is indispensable during digital forensics investigations. So far many approaches for the recovery of digital images have been proposed. The main contribution of ...
متن کاملIn-Place File Carving
File carving is the process of recovering files from an investigative target, potentially without knowledge of the filesystem structure. Current generation file carvers make complete copies of recovered files. Unfortunately, they often produce a large number of false positives – “junk” files with invalid formats that frequently consume large amounts of disk space. This paper describes an “in-pl...
متن کاملClassification 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 reco...
متن کاملUsing parallel processing for file carving
File carving is one of the most important procedures in Digital Forensic Investigation (DFI). But it is also requires the most computational resources. Parallel processing on Graphics Processing Units have proven to be many times faster than when executed on standard CPU. This paper is inspecting the algorithms and methods to use parallel processing for development of file carving tools that wi...
متن کاملOptimal Path Construction for Fragmented File Carving
Fragmented File carving is an important technique in Digital Forensics to recover files from their fragments in the absence of the file system allocation information. In this paper, the fragmented file carving problem is formulated as a graph theoretic problem. Using this model, we describe two algorithms, “Optimal Carve” and “Probabilistic-based Carve”, to perform file reconstruction and recov...
