Security enhancement in video based on gatefold technique for copyright protection

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.
