This chapter presents a DWT-DCT-based audio watermarking method using SVD and quantization [22, 23]. In the proposed method, initially the original audio signal is segmented into non-overlapping frames. DWT is applied to each frame and detail coefficients are represented in matrix form. DCT is...
In this work, a video watermarking technique based on Discrete Wavelet Transformation (DWT) and Fast Fourier Transformation (FFT) is proposed. The proposed watermarking scheme does not require the original host video during extraction process. Here selected frames of the video are decomposed using sec...
Hybrid DWT-DCT-SVD based Digital Video Watermarking For Mid Band Frequency Using Improved Artificial Bee Colony Optimization Algorithm Watermarking is a component of inserting data into the multimedia, for example, image, audio or video. This paper propose a method for video watermarking using hybrid...
The proposed audio watermarking embeds binary bit information into a digital media in the form of audio. The absence of damage to the media that is inserted information is a must in this process. In this research, Discrete Wavelet Transform (DWT) is combined with Histogram Au...

The invention discloses a DWT-SVD-ICA-based digital audio watermarking algorithm. The algorithm is performed according to the following steps: the first step, preprocessing is performed on an original audio signal, and a watermark is embedded in a selected appropriate segment; the second step, ...
In this work, a hybrid approach is presented to perform audio watermarking by using DCT and DWT approaches. In this paper, the presented research model is presented along with proposed algorithm. The implementation results shows that the presented work has provided effective results. The work is ...
In this paper an audio zero watermark scheme based on energy relationship between adjacent audio sections has been proposed. Because of audio watermarking algorithms are not easy to develop. The human ear is far more sensitive than other human sensory organs like eyes. The host audio signal is ...
This resulted in the development of a combination of DWT-SVD-Firefly (Firefly algorithm) watermarking algorithm. In this new implementation, the embedding depth was generated dynamically thereby rendering it more difficult for an attacker to remove, and watermark information was embedded by manipulation...
