A new algorithm for information hiding in digital image

Abstract

For information hiding, the robustness of a watermarking scheme against various attacks is an essential importance. Many proposed robust watermarking schemes may achieve good robustness but sacrifice the good quality of the watermarked image and lack of anti-noise ability. This paper proposes a transparent robust watermarking scheme which embeds the secret information in digital image. ICA method is employed in this paper to filter the Gaussian white noises. This ICA algorithm technique can guarantee transmitting the good visual quality of a watermarked image within strong Gaussian noises. Simulating result shows that the proposed watermarking method can achieve higher robustness performance.
