Abstract

The invention relates to a reversible data hiding method and system based on a prediction errors, and the method comprises the steps: partitioning an image, and obtaining a shadow part and a blank part; carrying out first-layer embedding processing on the shadow part; carrying out multi-layer embedding processing on the blank part; extracting the outermost layer information of the blank part afterthe multilayer embedding processing; and extracting the information of the shadow part after the first layer embedding processing. The problem of image distortion during high-capacity data embeddingcan be effectively solved.

Description

technical field [0001] The invention relates to the field of image encryption, in particular to a reversible data hiding method and system based on prediction errors. Background technique [0002] With the development of Internet technology, various information security issues have been brought about during the transmission of information. Steganography is about information hiding, that is, not letting anyone other than the intended recipient know about the transmission of information (and not just the content of the message) is a skill and science. Among them, the reversible data hiding method not only hides the data into the digital image secretly, but also the original image embedded data can be completely restored after being extracted. Reversible data hiding has many application scenarios due to its reversible characteristics. It is an ideal choice for occasions that require high fidelity, such as military secrets, legal certification, and telemedicine. Among the meth...
