Recent improvements in technology enable digital content to be amended and accessed without significant specialist delivery and without restrictions. Without emerging safety techniques, it is highly challenging to rely on digital storage and communication systems for commercial, military, and medical uses. The watermarking process is one technique that assists in safeguarding digital assets from unauthorized access. In the present article, many watermarking systems for videos are addressed, which are based on transformation techniques including principal component analysis (PCA), discrete wavelet transformation (DWT), discrete cosine technique (DCT), and discrete Fourier transform (DFT).
