Overlapped scheme for neighboring similarity method in video-based data hiding
Diksy Media Firmansyah, Tohari Ahmad · 2016
Basic component of digital video is digital images which are called frames. In a video, neighboring frames have similar pattern where a secret message can be embedded. Some research has been done by generating an integer matrix called prediction error. This method has been able to increase the secret message size which can be hidden. Their performance, however, is still not satisfying. In this paper, we extend the prediction error generation process by overlapping frames. According to the experimental results, our method has been able to accommodate more secret messages and maintain the video quality (i.e., more than 40 dB of PSNR value).
