File Format
Name F5
Ontology

F5 by Andreas Westfeld is an algorithm for BMP, GIF, and JPEG steganography.

Release 11 adds the switch "-c comment" to change or remove the default comment in the file. The JPEG compressor's comment header "JPEG Encoder Copyright 1998, James R. Weeks and BioElectroMech. " is very uncommon. If you change (or remove: -c "") the comment header, also the version of the APP0 marker is changed to the more common version 1.01.

nsF5 (non shrinkage F5) is an evolution of F5 that can hide more information.
