Spread Spectrum based M-ary Modulated Robust Image Watermarking
Spread Spectrum (SS) modulation principle has been widely used in digital watermarking due to its distinguishing characteristics viz. excellent security and robustness in performance. The use of wide spectrum of the host signal in message hiding process puts a limit on the data rate subject to a given embedding distortion. In SS communication the use of M– ary modulation is a popular extension ...
متن کاملPerformance Improvement in Spread Spectrum Image Watermarking Using Wavelets
This paper investigates the scope of wavelets for performance improvement in spread spectrum image watermarking. Performance of a digital image watermarking algorithm, in general, is determined by the visual invisibility of the hidden data (imperceptibility), reliability in the detection of the hidden information after various common and deliberate signal processing operations (robustness) appl...
متن کاملComparative performance of watermarking schemes using M-ary modulation with binary schemes employing error correction coding
A common application of digital watermarking is to encode a small packet of information in an image, such as some form of identification that can be represented as a bit string. One class of digital watermarking techniques employs spread spectrum like methods where each bit is redundantly encoded throughout the image in order to mitigate bit errors. We typically require that all bits be recover...
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 ...
متن کاملImproving Spread Spectrum Based Image Watermarking Through Non-binary Channel Coding
In this paper, we investigated on how to combine M-ary modulation with shortened Reed-Solomon (RS) codes, in the context of spatial spread spectrum based watermarking schemes. Analytical expressions and bounds for the bit error rate are derived and compared with empirical results for several types of images. It is shown that, for low output error rates, there exists an improvement in performanc...
