Reversible digital watermarking has been indicated as the technology to be adopted when image security is to be granted in a medical application scenario. The work presented hereafter provides a new lossless watermarking algorithm designed to really be integrated in a Picture Archiving and Communication System matching the requirements coming from radiological experts. The proposed technique has been developed by modifying and improving the methodology implemented in [3]. Experimental results carried out on medical imagery are provided to demonstrate performance enhancement.
