A New Images Hiding Scheme Based on Chaotic Sequences

摘要

We propose a data hidding technique in a still image. This technique is based on chaotic sequence in the transform domain of eovert image We use different chaotic random sequences multiplied by multiple sensitive images, respectively, to spread the speetrum of sensitive images. Multiple sensitive images are hidden in a eovert image as a form of noise. The results of theoretical analysis and computer simulation show the new hiding technique have better properties with high security, imperceptibility and capacity for hidden information in comparison with the conventional scheme sueh as TSB (Least Significance Bit).
