Image-based JPEG steganography

Matúš Jókay, Tomáš Moravčík

Abstract


This paper deals with the steganographic algorithm LSB (modi-

cation of the Least Signicant Bits) in JPEG images. The focus is on minimizing of the number of modied DCT coeffients using $(2^k-1, 2^k-k-1) $ Hamming
codes. Experimental part of the paper examines the dependencies between the
coding, efficiency and saturation.
