Digital watermarking is the process of embedding a digital signal within digital media for copyright or authentication purposes. Digital image authentication is a major concern for the digital revolution because it is simple to alter any image. In the past few decades, ensuring the authenticity of digital images has been an imperative concern for researchers. Several suitable watermarking techniques have been developed based on the intended applications to address this concern. However, it is challenging to develop a watermarking system that is both robust and secure. This paper proposes digital watermarking techniques using DWT, SVD, and ECC algorithms with the random spread technique, which has been shown to enhance the output image quality. SVD-based watermarking modifies the singular values of the host image, whereas DWT-based watermarking modifies the coefficients of the high-frequency sub-bands of the host image. In contrast, ECC-based watermarking generates a digital secret using the owner's private key, which is then embedded in the watermark using a secret key. The DWT and SVD techniques offer excellent imperceptibility and robustness, whereas the ECC-based technique offers high security and authenticity. The simulation of these techniques is carried out using MATLAB, and the simulation results demonstrate their efficacy in terms of PSNR, MSE, and RMSE and normalized cross-correlation (NCC).
