The invention discloses a reversible information hiding method and system for a hyperspectral image, and the method comprises the following steps: carrying out the anti-overflow / underflow operation of a pre-selected carrier image, and recording the position image information for the restoration of the carrier image; carrying out non-overlapping partitioning on the processed carrier image to obtain a plurality of pixel blocks; setting a complexity threshold value; sequentially sorting the pixels in each pixel block to obtain a pixel to be predicted of each block; calculating the complexity of the to-be-predicted pixel, and sequentially guiding the embedding operation of each pixel according to the relationship between the complexity and a complexity threshold value; and embedding auxiliary information required by decoding into the image. According to the method, the embedding performance of the reversible information hiding algorithm based on prediction can be improved, and the effectiveness of the method is verified through experiments.
Description
Technical field [0001] The present invention belongs to the field of information security, which relates to a null domain-based reversible information hidden field, and more particularly to a high-spectral image reversible information hiding method and system. Background technique [0002] The reversible information hidden algorithm is an emerging information security technology that hides the secret information hides the public carrier image, which hides the presence of secret information and the presence of secret information; the recipient can restore the original The carrier image is therefore widely used in the fields of military, aerospace, finance, medical, etc. have high quality requirements for carrier images. [0003] The two main indicators pursued by the reversible information hidden algorithm are embedded capacity and carrier distortion. The embedded capacity refers to the total amount of the secret information that can be hidden in an image of a carrier image, and t...
