![]() ![]() As well as selected the best frames in this algorithm increased the difficulty and give us the best stego-video quality using structural similarity (SSIM). The proposed algorithm selected the best frames to hide the message in video using 3D distance equation to increasing difficulty onto the intruder to detect and guess the location of the message in the video frames. This paper presents the algorithm of steganography in the video frames. Steganography process in a video is to hide the information from the intruder and prevent him access to that hidden information. Steganography is a technique to hide information within cover media so that this media does not change significantly. Therefore, field of steganography become interested as the need for security increased significantly. Steganography techniques have taken a major role in the development in the field of transferring multimedia contents and communications. The results proved that proposed method is effective, efficient and provided high security, high capacity, not malformed text and resistance against several steganalytic attacks Lastly, relying on the matching fitness value, the steganography process is done by replacing (transposition) the secret's letters with cover's letters. The SFO works to determining the matching fitness value between the cover and secret message and generates a key to recapture secret message. The fitness values of the cover and secret message are calculated by using a new way. In this work, the (SFO) is utilized to enhance the security and reduce the disfigurement to obtain best message quality, where the SFO has advantages in the term of security and text quality. In this paper a new steganography method for concealing message in message by using sailfish optimizer (SFO) and transposition method is proposed.
