An effective and secure video watermarking using hybrid technique

Abstract

Now, all satellite channels handle high-quality data, including HD video files (1 K, 2 K, and 4 K). High-quality compression software is required to archive and transmit these files accurately and efficiently. HEVC is a standard development technique for high-quality video compression which can produce double compression while preserving video quality. On the other hand, the use of a robust digital video watermark algorithm can solve copyright issues for these types of categories. Therefore, in this paper, an efficient compression-based secure digital watermarking is proposed. In this paper, initially, the video are converted into number of frames. Then, we de-compose the frame using dual-tree complex wavelet transform. After that, to increase the security of the system, the embedding positions are optimally selected using adaptive cuttlefish optimization algorithm. Then, the secrete images are encrypted using elliptic curve cryptography algorithm. After that, the encrypted images are converted into binary bit. Then, the binary bits are embedded into the selected position of video frame. After the encryption process, to decreases the size of encrypted document, H.265 video encoding approach is applied. This method is, effectively, reduce the size of the image, without affecting quality of the image. Finally, the compressed image is transmitted to the receiver. The reverse process of embedding is used for extraction process. The performance of proposed approach is analyzed in terms of different metrics and effectiveness compared with different methods.
