ABSTRACT This paper deals with the steganographic algorithm LSB (modification of the Least Significant Bits) in JPEG images. The focus is on minimizing of the number of modified DCT coefficients using (2k − 1, 2k − k − 1) Hamming codes. Experimental part of the paper examines the dependencies between the coding, efficiency and saturation.
