In this paper, a new robust image watermarking technique adopting an optimum encoding framework is proposed. This technique namely, the twin image watermarking algorithm TIWA, utilizes a particular kind of optimum two dimensional codes, based on complete complementary codes, for the introduced watermark encoding process. The TIWA algorithm is first presented for single user, then supported with the optimum code arrays properties, is developed to support multi-message hiding. The enhanced robustness, the developed security, and the remarkable performance compared to conventional technique are the main advantages of the proposed technique shown by the simulation results
