Abstract
An effective asymmetric watermarking procedure has been recently devised in literature, named Transformed-key Asymmetric Watermarking (TKAW). A weakness point of this system is its vulnerability against projection attacks, as well shown by Chen and Ye. This work discusses a modified version of the TKAW to provide robustness against projection attacks, by means of a non-linear transformation, without increasing the computational complexity of the original method but with the same performancesFile in questo prodotto:
