Watermarking pada Citra Digital dengan Menggunakan Metode DCT-SVD
Abstract - Watermarking is a technique of hiding information on a particular digital media, such as images, sound or video. In this research, the watermark insertion used the DCT and SVD method. The watermark insertion process used the Ruizhen Liu and Tieniu Tan algorithm, watermark image was inserted into a singular matrix of the host image which was obtained from the decomposition process using SVD. The watermarking criterias used to test the performance were fidelity, recoverable, robustness and imperceptibility. The best method is Non DCT-SVD with the alpha value of 0,1. The MSE and PSNR values obtained are 2,25 dB and 40,10 dB on the flower1.JPG testing data, 0,56 dB and 53 dB on the flower2.JPG testing data, 2,86 dB and 39,56 dB on the flower3.JPG testing data.
