This paper presents a robust method for embedding and extracting watermarks in video frames using Discrete Cosine Transform (DCT). The method ensures high imperceptibility and maintains the quality of the video while embedding the watermark in the luminance component of each frame. Extensive experiments demonstrate the method's robustness against common video processing operations, including compression, noise addition, and cropping. The proposed approach is computationally efficient, making it suitable for real-time applications. Future work aims to optimize the algorithm for faster performance and enhance robustness against more sophisticated attacks. Practical applications include digital rights management, content verification, and forensic analysis.
