چکیده

A synchronization code improvement scheme based on moving average is proposed for robust audio watermarking in the paper. Prior work has shown that the synchronization code scheme based on moving average is robust, but it was suitable for the same rule was adopted in embedding watermark and synchronization code, and the imperceptibility and the search efficiency isn’t be paid attention to. Hence, in this paper, we improved the original scheme. The main contribution of this paper is as following: (1) improve the algorithm in surviving from desynchronization attack, (2) improve the scheme in inaudibility, (3) optimize the choice of parameters, (4) analyze the imperceptibility of the scheme, and (5) comparison of robustness and search efficiency with other synchronization code schemes. The experimental results show that the proposed watermarking scheme maintains high audio quality and is robust to common attacks such as additive white Gaussian noise, requantization, resampling, low-pass filtering, random cropping, MP3 compression, jitter attack and time scale modification. Simultaneously, the algorithm has high search efficiency and low false alarm rate.

A Robust Digital Image Watermarking Scheme Based on DWT

In this paper a wavelet-based logo watermarking scheme is presented. The logo watermark is embedded into all sub-blocks of the LLn sub-band of the transformed host image, using quantization technique. Extracted logos from all sub-blocks are merged to make the extracted watermark from distorted watermarked image. Knowing the quantization step-size, dimensions of logo and the level of wavelet tra...

Robust Audio Watermarking Algorithm Based on Moving Average and DCT

Noise is often brought to host audio by common signal processing operation, and it usually changes the high-frequency component of an audio signal. So embedding watermark by adjusting low-frequency coefficient can improve the robustness of a watermark scheme. Moving Average sequence is a low-frequency feature of an audio signal. This work proposed a method which embedding watermark into the max...

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 ...
