DFRWS 2006 Forensics Challenge Overview

Overview  |   Challenge Details   |   File Image Layout   |   Results

Data carving is the process of extracting a collection of data from a larger data set. Data carving techniques frequently occur during a digital investigation when the unallocated file system space is analyzed to extract files. The files are "carved" from the unallocated space using file type-specific header and footer values. File system structures are not used during the process.

The results of existing file carving tools typically contain many false positives. An investigator must test each of the extracted files by opening them in an application that supports the file type. The goal of the DFRWS 2006 Forensics Challenge was to design and develop file carving algorithms that identify more files and reduce the number of false positives.
