Digital Watermark Algorithm Using Image Relocation and Traversal Detection for Remote Sensing Image

    Abstract: A blind watermarking algorithm based on image relocation and traversal detection for remote sensing image was presented.In the watermark embedding processing,the image was segmented by block and the low frequency of DCT was got.Then,the watermark was embedded in the low frequencies based on the quantitive method.Lastly,the inverse DCT was done,and the watermarked image was obtained.In the watermark detecting processing,the location of image was determined by the image expansion.The correct watermark information was got by the inverse process of the watermark embedding.Experimental results show that the method can effectively resist compression,filtering and other common image processing attacks,but also effective against cutting attacks.
