Contribution
It introduces a novel steganographic method leveraging Lehmer code and palette transformations for blind detection in palette images.
Findings
Effective blind detection without cover image modification
Utilizes palette color permutations for data embedding
Achieves reliable data extraction through palette-RGB transformation
Abstract
To hide a binary pattern in the palette image a steganographic scheme with blind detection is considered. The embedding algorithm uses the Lehmer code by palette color permutations for which the cover image palette is generally required. The found transformation between the palette and RGB images allows to extract the hidden data without any cover work.
