Video is compressed to move the redundancies for efficient communication. In this paper, we use a steganography method for verification of the video content at the receiver side. The main idea of the proposed steganography method is based on the Discrete Cosine Transform (DCT). It is based on creating a signature for each block of the DCT of the compressed video sequence to be embedded in another block. This is attributed to the fact that most DCT coefficients of the compressed video sequence are either zero or close to zero. Simulation results reveal the robustness of the suggested steganography method.

The videois compressed to move the redundancies for reducing the number of bits whichneed to show the video for reducing the size of video to reduce the band width. We embed the hiding data in redundancies of the video frame withoutvisibility manner using Steganography technique. In our research we focus in increasing the improvement of compressed video frame through using steganography. In our research we use two mixed techniques to compress the video, the first is digital steganography and the second is data compression. Hence, the suggested scheme is mixed the algorithm ofthe steganography algorithm with the DCT compressionvideo frame.The suggested scheme in our study compression of data is made in two steps. In the first step,redundant data isminimized by compaction of energy using video. In the second step, with using steganography bit blocks isembedded in its blocks which call subsequent of the same video frame. Theadvantage of thebits which it is embedded isdecrease the size of the file and increase thesize of the file of the compressed video frame, but also decrease the file size further more. Theresults of simulation results explainthat,the suggestedschemehave more potential in coding of the frame of the video.
