The robustness performance is prominent against most attacks such as pepper and salt noise, speckle noise, MPEG-4 compression, and motion JPEG 2000 compression. The capacity is investigated and shows good improvement. During the whole process, the cover video remains original without any modification and has a strong ability to resist steganalysis. At the receiver, through calculating hash sequences of RHOOF from the cover video, the secret information can be extracted successfully. The hidden information bits are mapped to the hash sequences of RHOOF, and the corresponding indexes are sent by the sender. For every video in the database, the robust histograms of oriented optical flow (RHOOF) are obtained, and the index database is constructed. In this study, a coverless steganography scheme based on motion analysis of video is proposed. With the rapid development of interactive multimedia services and camera sensor networks, the number of network videos is exploding, which has formed a natural carrier library for steganography.
