Advanced Watermarking and its Applications
نویسندگان
چکیده
Audio watermarking is a technique for the transmission of additional data along with audio material within existing distribution channels. Recent research has produced a number of algorithms for the embedding and retrieval of watermarks in audio signals. While most known systems operate in the linear domain, few are capable of embedding watermarks into compressed material. This paper investigates the different areas of applications and their specific requirements with respect to watermarking technology. Both watermarking in linear and compressed domain are contrasted in their concepts and properties and recent technological advances are described. ————————————————————————

Optimum 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 ...

This paper investigates digital data hiding schemes. The concept of information hiding will be explained at first, and its traits, requirements, and applications will be described subsequently. In order to design a digital data hiding system, one should first become familiar with the concepts and criteria of information hiding. Having knowledge about the host signal, which may be audio, image, ...

Watermarking systems have specific feathers in accordance with their applications. In many applications transparency and robustness are needed which are the most important features. These two features are in contrast to each other and are controlled by a parameter named watermark strength. With decreasing the watermark strength, transparency of the watermarking system increases while the robust...

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...
