HUGO Source Code

The Highly Undetectable steGO (HUGO) algorithm is a state-of-the-art spatial-domain steganography algorithm that is highly resistant to known steganalysis techniques. It was originally published in “Using High-Dimensional Image Models to Perform Highly Undetectable Steganography” and an implementation was made available for the Break Our Steganographic System (BOSS) contest. Unfortunately, the links on the BOSS contest website have been dead for some time. We are therefore hosting this content here as it is no longer available on the internet.

  • Implementations of HUGO embedding simulation, SPAM features extraction and tools for using with LibSVM, for Unix-based systems. This implementation has been updated to work on Ubuntu 12.04 through 16.04 LTS.
  • The BOSSbase image database is available from a different link to the one advertised on the BOSS contest website. This link is provided here for convenience.
