چکیده

The paper presents the results of implementation in the Matlab environment for watermarking embedder and extractor based on the Direct Sequence Spread Spectrum (DSSS). A block diagram of watermarking system, an analysis of watermarked signal reproduced as well as watermarking system robustness to degrading factors: lossy compression, signal-to-noise ratio (SNR) as well as a change in sampling frequency, were shown.

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 ...

A survey on digital data hiding schemes: principals, algorithms, and applications

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, ...

From Image to Audio Watermarking Using Self-Inverting Permutations

The intellectual property infringement in music due to the proliferation of the internet and the ease of creating and distributing identical digital objects has brought watermarking techniques to the forefront of digital rights protection. Towards this direction, a significant number of watermarking techniques have been proposed in recent years in order to create robust and imperceptible audio ...
