JPEG attribution

FEATURES MOVED, REPOSITORY DISCONTINUED

• The attributes which found to perform the best (attributing jsteg, f5 and outguess) have been implemented in a new JPEG analysis tool called JPEG investigator.
• This repository will remain online only for transparency reasons; it was used to generate data in "Stego-Malware Attribution: Simple Signature and Content-based Features Derived and Validated from Classical Image Steganalysis on Five Exemplary Chosen Algorithms" (SECURWARE '23, p. 33-42).

More efficient implementation in Python featuring more detailed evaluation of identified jpeg stego attributes.
