Augmented Watermarking
نویسندگان
چکیده
We introduce the concept of augmented watermarking in which in addition to the hidden watermark placed within the image an explicit watermark-dependent random sequence (noise) is added to it. The receiver first detects the watermark, computes the random sequence for which the watermark serves as the seed, and then subtracts out this random sequence. This system can be devised with several watermark and noise layers which define a regime in which different users have different rights related to the quality of the signal.

A Modified Digital Image Watermarking Scheme Based on Nonnegative Matrix Factorization
This paper presents a modified digital image watermarking method based on nonnegative matrix factorization. Firstly, host image is factorized to the product of three nonnegative matrices. Then, the centric matrix is transferred to discrete cosine transform domain. Watermark is embedded in low frequency band of this matrix and next, the reverse of the transform is computed. Finally, watermarked ...

متن کاملIntroducing Capacity Surface to Estimate Watermarking Capacity
One of the most important parameters in evaluating a watermarking algorithm is its capacity. Generally, watermarking capacity is expressed by bits per pixel (bpp) unit measure. But this measure does not show what the side effects would be on image quality, watermark robustness and capacity. In this paper we propose a three dimensional measure named Capacity surface which shows the effects of ca...

متن کاملOptimum decoder for multiplicative spread spectrum image watermarking with Laplacian modeling
This paper investigates the multiplicative spread spectrum watermarking method for the image. The information bit is spreaded into middle-frequency Discrete Cosine Transform (DCT) coefficients of each block of an image using a generated pseudo-random sequence. Unlike the conventional signal modeling, we suppose that both signal and noise are distributed with Laplacian distribution, because the ...
