An Information Hiding Method Based on Sampling Theory

Abstract

Abstract: In this paper, the sampling theory, combined with the nonlinear image transformation technique, is introduced as a method for image scrambling, providing a means for improving the imperceptibility and robustness of watermark algorithm. Practical examples are presented to illustrate the efficiency of the method.
