  Abstract

In this letter, we propose a novel subsampling based image watermark sequentially embedding scheme to reduce the risk of common permutation attack. The image is still perceptual after watermarking, and experimental results also show its effectiveness and robustness.

Key Words: DCT, watermark, subsampling, permutation, ordering

Manuscript received November 15, 2006.
