摘要：

Digital watermarking is a technique of hiding information for copyright protection and authentication. In this paper, an invisible digital watermarking algorithm on Discrete Wavelet Transform (DWT) and Discrete Cosine Transform (DCT) domains is presented. Herein, a binary watermark image was embedded in the middle sub-band coefficients of a video stream. The experimental results of proposed algorithm indicates that the PSNR values of the watermarked videos were as high as almost up to 37 dB with the optimal watermarking strength. The proposed algorithm was proven robust against HEVC stream compression. It is hence anticipated that it could be effectively applied for copyright protection and authentication.
