In this paper we make contributions to a non-blind multiple watermarking scheme that proceeds by embedding a binary image in the discrete wavelet transform bands of a gray scale image. Unlike the common wavelet based watermarking techniques, the proposed scheme lies essentially on marking the approximation and diagonal bands of the discrete wavelet transform (DWT) of the cover image achieving a better compromise between fidelity and robustness. Experiments show that our contributions provide the multiple watermarking scheme with robustness to a wide variety of attacks.
