Abstract: Most of the existing digital watermarking schemes mainly target a single or a few required objectives. The novelty of the proposed technique is to meet the four main objectives of the digital watermarking namely copyright protection, data authentication, usage monitoring, and user authentication. This scheme uses multiple watermarks for meeting these goals using discrete wavelet transform (DWT) and singular value decomposition (SVD) transforms. This technique achieves high peak signal-to-noise ratio (PSNR) and high robustness against average filtering, median filtering, salt and pepper noise, gamma correction, and contrast enhancement attacks. The experimental results show that the proposed method is effective in achieving four primary goals of watermarking. The validation of the proposed technique is tested using the images from BOWS and SIPI datasets.
