Hiding Data in Videos Using Optimal Selection of Key-Frames

摘要

Video steganography is the technique where the users keep their data secret, which also embeds and extracts the data. It has lots of information stored in each and every frame. Moreover, the particular key-frames in each video are extracted using the average threshold algorithm. The data is hidden inside the least bit of the selected key frames. The presence of message in video will not be visible by attackers since it is available only for a fraction of time. Using this methodology, the performance of video steganography has been increased effectively.
