“…In the system-based transform domain watermarking approach, a host frame in a video sequence is transformed into a new domain before the watermark is embedded [20]. The most widely used transforms include fast Fourier transform (FFT) [21], discrete cosine transform (DCT) [22], discrete wavelet transform (DWT), dual-tree complex wavelet transform (DTCWT) and singular value decomposition (SVD) [23,24]. Each of these transformations, which are used to simulate video frames in multiple ways, have unique characteristics.…”

Watermarking digital media content could undoubtedly discourage and prevent such illegal sharing activities, safeguarding the copyrights of the original creators. Such content could make use of invisible watermarking, not just for robustness and security, but also for imperceptibility. The proposed research presents a frame selection strategy based on the difference between the absolute histograms of consecutive frames. To increase security and robustness and avoid embedding the watermark frame by frame, ten frames with the maximum absolute histogram value are selected for watermark embedding. The size of the watermark would determine the number of nonoverlapping blocks that a key frame is divided into in order to embed the watermark. The watermarks are embedded into the LSB of the frame-blocks, which have the most matched location where the embedding error will be minimum with high imperceptibility. Security can be further enhanced by generating a secret key based on non-sequential video frames, block location, and watermark size. The proposed method surpasses other comparable methods in terms of imperceptibility and robustness to image processing and geometrical attacks, and it is also computationally inexpensive. The results of the proposed method outperformed the best state-of-the-art methods in MPSNR and MNCC by 16 dB and 0.018, respectively.

“…Watermarking is a derivative of steganography, which has resistance to attacks (hackers), even though the inserted data is visible in the document that using by other parties. A watermark (watermark) is data that attached to a digital document, whether video, audio, text, where its presence does not affect the further processing of the document [2][8] [9]. This watermarking program works by inserting a watermark image into the original image to get an image containing a watermark.…”

“…For example, there is a matrix A with m rows and n columns, and the rank r≤n≤m.. Matrix A can be decomposed into 3 matrices, that is, A=USVT. The analogy of the number of rows and columns of the U, S, and VT matrices [2]. Matrix U is an orthogonal matrix mxm : U=[u1,u2,...ur+1,...,um]; Vector ui, for i = 1,2,...,m comes from the orthogonal set…”

“…As the use of watermarks is only considered an art in document writing, but in quotes from several journals, there are many other opinions stating, among others : Watermark is a technique of hiding data or information into other data to be "boarded" (host data), but people are not aware of the presence of additional data in the data host [1]. Applying Singular Value Decomposition (SVD) on the host image to determine the modified singular value by adding a watermark, then SVD is reused in the resulting matrix to calculate the modified singular value [2]. If a document that on the internet is in the form of text or images, if there is no copyright for the digital work, it will open up opportunities for copyright infringement of other people's works [3].…”

Watermark is a part of steganography that is used by many users in electronic and non-electronic documents. Watermark certainly does not guarantee the safe use or modification of the document, but only the legitimacy of ownership of the document.

Establishing a digital watermark will improve the owner's document security. Hiding a label by inserting datum bits in the image segment using Singular Value Decomposition (SVD), as a part of Watermarking. Watermark domains are digital documents in the form of videos, images, text, sound. Watermarking applications built by applying singular value decomposition to numbers
