Boato, Giulia and De Natale, Francesco G. B. and Fontanari, Claudio and Melgani, Farid (2005) Hierarchical ownership and deterministic watermarking of digital images via polynomial interpolation. UNSPECIFIED. (In Press)
This paper presents a novel method for the secure management of digital images formulated within the mathematical theory of polynomial interpolation. As main innovative features, our approach is based on a hierarchical joint ownership of the image by a trusted layered authority and on a deterministic watermarking procedure, embedding a short meaningful or random signature into the image. Experimental results show that the inserted signature can almost always be fully recovered even in presence of a reasonable amount of image degradation due to image processing operators, such as filtering, geometric distorsions and compression.
