Blind Audio Watermarking in Transform Domain Based on Singular Value Decomposition and Exponential-Log Operations

Blind Audio Watermarking in Transform Domain Based on Singular Value Decomposition and Exponential-Log Operations

Digital watermarking has drawn extensive attention for copyright protection of multimedia data. This paper introduces a blind audio watermarking scheme in discrete cosine transform (DCT) domain based on singular value decomposition (SVD), exponential operation (EO), and logarithm operation (LO). In our proposed scheme, initially the original audio is segmented into non-overlapping frames and DC...

A Robust Blind Audio Watermarking Scheme Based on Singular Value Decomposition and Neural Networks

Robust Blind Image Watermarking Based on Multi-wavelet Transform and Singular Value Decomposition

Digital watermarking is a technique for copyright protection of multimedia products such as digital images, which embeds a watermark into a host image. The main challenge in image watermarking is the development of new robust methods against different attacks. This paper presents a robust blind watermarking scheme based on multiwavelet transform (MWT) and singular value decomposition (SVD). By ...

Self-synchronized digital audio watermarking using discrete wavelets transform and singular value decomposition

A self-synchronizing, robust, and inaudible audio watermarking algorithm has been proposed in this paper. The synchronization codes are embedded into the audio along with informative data, to enable self-synchronization capability of embedded data. The algorithm effectiveness brought by successive application of two powerful mathematical transforms: discrete wavelets transform (DWT) and singula...

Robust image watermarking based on discrete wavelet transform-discrete cosine transform-singular value decomposition

With the rapid growth of network multimedia systems and other numerical technologies, images, audio, text and video can be more easily produced, processed as well as stored by digital devices in recent years. To conceal data in transmitting message for copyright protection the secret is very important. Various Digital Watermarking Techniques are developed to protect the secret data. This paper ...
