Abstract:

This technical report summarizes the work performed under the Detector and Extractor of File prints, DEF, Extension contract for the Air Force Research Laboratory, Rome Research Site, Information Directorate. The focus of the underlying effort was comprised of an improved file tamper protection scheme, new data stream MIME-type identification techniques and improving a portable Java implementation designed to demonstrate that functionality. The existing tamper detection capabilities were enhanced to allow for greater localization of tampering while minimizing storage requirements for the created outputs. Data stream MIME-type identification techniques were expanded to include the use of new statistical DEF measurements and Bayesian classifiers. The report provides conclusions and recommendations on the development, implementation and enhancement of new and existing data integrity and data forensics features using the DEF algorithm.
