Security and robustness are the main significant properties in watermarking system. In this paper, we propose an effective and secure certificateless public key watermarking scheme based on Singular Value Decomposition (SVD) and Discrete Wavelet Transform (DWT). The proposed method guarantees the non prior knowledge two parties to communicate covertly over an insecure and public channel. Moreover, we examine the robustness of the proposed scheme by analyzing different, original and watermarking images. The results demonstrate that our scheme fulfills all the security requirements of watermarking system and it is a powerful against various types of advanced attacks.
