It has been claimed that quantization-based data-hiding methods offer an advantage over spread-spectrum schemes. In this paper we review this assertion by presenting a new look on the assumptions made for these claims, and we give a new performance comparison between both approaches under random additive channel distortions. The existence of a threshold in the distortion level for the goodness of each of the methods is shown.
