Andy Bair, Klayton Monroe, and Jay Smith were announced as winners of the 2006 File Carving Challenge at the 6th Annual Digital Forensic Research Workshop (DFRWS). Challenge participants were asked to develop new tools and techniques to extract as many files as possible from a DFRWS-prepared data set while reducing the number of false positives. Data carving techniques are used during digital forensic investigations and existing file carving tools typically produce many false positives.

Andy will present the results of the challenge, following this draft outline.
