المستخلص: The growth of IT and telecommunications is becoming very relevant in terms of safety, security can be performed using steganography, and in the field of information security steganography plays an important role. In this paper, a steganography algorithm is proposed to hiding a confidential message inside a video for the purpose of sending it to another party without attract the attention of attacker and unauthorized parties and with high security and a high embedding rate. This is done by embedding the secret message and distributing it between the video frames in a certain way using steganography techniques. The proposed method is implemented by using several steps. In first step: it divided the video in number of frames, the next step: is encrypt the secret message using AES algorithm, after encryption process the message is hiding in frames of video, for each ten frames select one frame video to hide secret message in it. And the final steps: is using secret key (n+5) this key is use to determine the locations of the pixels in order to hide bits of secret message in a blue color channel by using pixel value difference (PVD), it uses zigzag columns for hide the encryption secret message in each location based on secret key. In addition to that, the proposed method has removed the limitations of the (PVD) method. The outcomes of the proposed system are good in security, transparency, efficient, high capacity, and powerful. Because, it uses measurements of peak signal to noise ratio (PSNR), mean square error (MSE), entropy, and correlation coefficient. This system is preventing by attackers to detect the encryption secret message.
