Matrix Encoding for Data Hiding Using Multilayer Video Coding and Transcoding Solutions
This paper proposes a multitier data hiding solution in MPEG video using matrix encoding. In the first tier of the proposed solution, raw video is encoded into two layers using multilayer Signal to Noise Ratio (SNR) encoding. ...
Data Hiding in MPEG Video Files Using Multivariate Regression and Flexible Macroblock Ordering
This paper proposes two data hiding approaches using compressed MPEG video. The first approach hides message bits by modulating the quantization scale of a constant bitrate video. A payload of one message bit per macroblock ...
