  • Patent number: 11838530
    Abstract: A method for concealing data in an image or a video stream inside a compression chain, being implemented by a computer and including a structuring and processing phase, during which at least one image is structured into blocks including coefficients, a phase of converting and quantifying blocks so as to generate converted and quantified coefficients, with entropic coding intended to code the converted and quantified coefficients. The method includes a step of concealing data, during which bits of the data are concealed by modifying converted and quantified coefficients located in a high frequency zone of at least some of the blocks that relate to the luminance component of the video stream and that are intra-coded. This modification is performed after the quantification but before the entropic coding.
