Abstract :
This paper presents a novel method for steganographic image watermarking with two main innovative features: i) it involves a hierarchical control, committing the watermark reconstruction to a trusted layered authority; and ii) it is deterministic, embedding a short meaningful signature into the cover image. Experimental results show that the embedded signature can be accurately recovered even in presence of a reasonable amount of image degradation due to image processing operators, such as filtering, geometric distorsions and compression.
