Title: METHOD AND APPARATUS FOR DATA HIDING IN PREDICTION PARAMETERS
Abstract:
A decoding device for decoding a target information from a bitstream of video data, wherein the bitstream comprises a prediction parameter encoded in the bitstream, the decoding device comprising: a computation unit configured to calculate a randomized host signal based on the prediction parameter and a pseudo-random signal, and a check unit configured to apply a check function to the randomized host signal and to thereby obtain the target information.
