Copyright infringement is a serious problem in the creative industry especially with the massive growth of digital content creations. Digital watermarking is a method that could be used for protecting copyright infringement. The aim is to embed a digital watermark secretly into the digital content (image). This paper proposes Discrete-Haar Wavelet Transform (DHWT) method and (LSB) steganography method for digital watermarking. As a demonstration of concept, an application is developed for watermarking color images. The testing and evaluation results show that the average PSNR for images with 512×512 pixels resolution is 76.918 dB, for images with 1024×1024 pixels resolution is 85.065 dB, and for images with 2048×2048 pixels resolution is 85.15 dB.
