Authentication of video based on concatenated plane slicing layers approach

Abstract

Protection of digital contents yields more attention towards society. The proposed approach aims to authenticate the video based on the horizontal concatenation approach. Initially, the selected video frame isolates the luminance, chrominance red, and chrominance blue layers. Further, slice each layer and concatenate them slice horizontally. Now focus on the middle region concatenated layered image and introduce the single level wavelet transform. A watermark image is divided vertically and one of the portions is concealed with vertically half of the approximation band (LL₁), it merged similarly another half of the watermark image with vertically half of the medium level band (LH₁). In this approach, the different scaling factor values (α =0.1 and β = 0.01) are used to achieve better PSNR. Apply the Inverse Discrete Wavelet Transform to bring back the normal concatenated frames. Next, group the luminance, chrominance red, and chrominance blue layers and stack to gain the marked video frame. Since this strategy is a non-blind technique, hence the copyright image can be established by using the same procedure of watermarked and non watermarked video frames. This approach aims to minimize the bit error rate and enhances the robustness.
