“…Therefore, although the visual quality of the video is not affected by this type of attack, this type of attack causes the destruction of the watermark. So it is advisable to be evaluate any proposed system of video watermarking versus temporal attacks [24]. Tables- (1,2) shows that the proposed watermarking algorithm's indices are highly robust against almost all types of attacks.…”

This paper adopted a new video watermarking scheme based on hybrid transforms to achieve the watermarking requirements, that is, robustness, imperceptibility, and security. Where In our system first of all, the original video will be divided into frames to transform it using the Slantlet Transform into four sub-bands (i.e., LL, LH, HL, and HH). Secondly, The HL sub-band will be chosen for further decomposition using Contourlet Transform (CT), and then the low subband of CT will be selected to decompose it to fixed size non overlapping blocks to employ the DCT (Discrete Cosine Transform) on each block. lastly, to improve the security and robustness, the watermark logo is scrambled using AT(Arnold transformation ) as a prelude to embed it's on the each transformed nonoverlapping blocks. Experimental results show that the proposed system achieves good imperceptibility and high resistance against various attacks.

“…Because of the fact that it is easier to obtain a high algorithm robustness in the transform domain, this type of algorithms is more popular compared to spatial algorithms. Among numerous proposed methods one may notice the large number of algorithms in the DCT [10,29,32] and DWT [4,26,47,51] domains (because of the fact that most popular lossy compression standards-JPEG and JPEG2000 operates in DCT and DWT). Also two transforms are used, e.g.…”

“…In addition, imperceptible methods may be further divided into those which use the perceptual models of a human being [4,55]-the Watson model may be given as an example [16,43]. There are many methods which do not take into account the perceptible models [9,17,18,27].…”

The protection of copyrights of digital images authors is one of the most important tasks set before watermarking. What is especially important is to ensure the high robustness of a watermarked images against attacks, preventing the reading of additional information about the author. In addition, the used processing of the original image must be absolutely invisible. The presented algorithm embeds information in a parallel way-independently of the luminance and chrominance matrices in the spatial and frequency domains. The main factor motivating the use of a parallel watermark embedding via the proposed way was the mutual complementing of robustness, offered by processing in spatial and frequency domains. Additional information is recovered in a 2D cepstrum domain and in coefficients of the cosine transform. The article shows a description of a mathematical model, tests of invisibility, effectiveness and the robustness of the method were carried out. The robustness of the algorithm was shown against the following attacks: JPEG and JPEG2000 lossy compression, noise, median filtering, Low-Pass and High-Pass filtering, desynchronization, simple and inverse D/A conversion, majority cropping, photomontage and affine transforms-rotation, scaling, shearing, translation.
