Fig. 5From: High-capacity reversible image steganography based on pixel value orderingFlowchart of the steganography method proposed in this study. The steganography steps proposed in this study are described as follows. (1) The LSB of the final pixel value in the digital image will be used to indicate whether the digital image is read in row or column order. (2) The cover image is read in row and column order, and the differences are calculated. (3) Block pixel ordering. (4) Construction of the location map LM(i). (5) Compression of the location map. (6) Processing of extra information. (7) Recording of extra information. (8) Hiding of confidential information. (9) Steganography of the original cover image is carried out according to step 8 until the confidential information is hidden completelyBack to article page
