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 is achieved. A second order multivariate regression is used to find an assoc...
