Abstract
Watermarking of multimedia gives more attention to the research society. This paper presents the non-blind watermarking technique on video; initially, a watermark is reshaped and grouped into odd and even row images. Next, the luminance band of the frame is shared into alternative pixel shares and it is concatenated. Further, gatefold operation is enabled on a concatenated luminance band. Now, single-level decomposition is imposed on the gatefold image and, the copyright marking process is enabled only on the medium level of frequency sub-bands. To enrich the robustness of the technique the marking fashion is in the upper diagonal layer region of wavelet sub-band. Next, an inverse wavelet is imposed to obtain the gate folded marked cover image. Further, the reverse process can be carried out to obtain the watermarked video frame. To prove authorship the cover and copyrighted image has subject to the same procedure and acquires the marked information. The main objective is to design and develop a gatefold based video authentication approaches with ownership information that can be used for copyright protection. Also increase the robustness, payload, and minimize the bit error rate. Keywords Authentication . Copyright protection . Cross-layered embedding . Gate folding approach . Watermarking .

1 Introduction Multimedia is the text, images, audio, movement, and other media together to frame a natural entire, to accomplish a specific capacity. An advanced image is a portrayal of two-dimensional images as a limited arrangement of computerized esteems called picture components or pixels.

Multimedia Tools and Applications
In the present time, a video is considered as a significant instrument that can consolidate all types of multimedia elements like text, audio, static and moving images because video provides transferring the huge capacity of information. While in the transmission of this computerized content, an unapproved individual may easily procure and control the information; right now, assurance of data and recognizing controls is a fundamental task [2, 7, 14]. Since the electronic data has no contention between like a unique and its duplicate [5, 6, 10]. Different scientists have been penetrated down the responses for copyright insurance. A procedure that portrays the patterns that hide the copyright data like digital media is called Copyright marking. Digital watermarking has gained more attention while proving the integrity and authenticity of the owner [20, 23]. Hence the industry and academic people are working seriously on digital watermarking. Watermarking can provide robustness an
