- W2183101311 abstract "These days’ data and multimedia is taking on digital format. To protect this data from any kind of intentional and unintentional attacks, a protection mechanism is needed. Watermarking is one of the methods to achieve data authorization and security of digital data. Watermarking is the process of inserting or hiding valuable information behind a cover work. This paper focuses on two digital watermarking techniques, Discrete Cosine Transform (DCT) and Discrete Wavelet Transform (DWT). DWT have been studied using the haar wavelet. Wavelets have strong capability of reconstruction thus preserving image quality and robustness under various attacks. We will calculate Peak Signal-to-Noise Ratio (PSNR) and Mean Square Error (MSE). For this purpose algorithms corresponding to both domains are implemented using MATLAB and the results are analyzed and compared visually and along with the parameters. It has been observed that DWT provides better results than DCT." @default.
