Abstract:

In order to implement watermarking scheme for embedded systems, we present an energy efficient and robust watermarking mechanism based on DS-CDMA. The DS-CDMA based watermarking can obtain the capacity according to the orthogonal spreading codes. The high capacity can improve the robustness efficiently. For power saving, we propose a low complexity frequency domain transform for the DS-CDMA embedding method. The experimental results show that our approach not only reduces 82.19% energy consumption, but can survive from various signal distortions such as JPEG compression, sharpening, blurring, intensity adjustment, and cropping.
