Labyrinth generation type information hiding and recovering method and device and readable storage medium

Abstract

The invention belongs to the crossing field of information security and information hiding, and discloses a labyrinth generation type information hiding and recovering method and device and a readablestorage medium. In hidding, an encryption backup sequence is generated for secret information through a secret key consistency strategy. Then coding expression is carried out through the initial mazenode wall state selected in a pseudo-random mode, and perfect maze covering is further formed. During recovery, the received maze is subjected to perfect maze inspection, secret information is further extracted from the maze image passing the inspection according to the secret key, and the reliability of the extracted secret information is inspected through secret key consistency inspection. According to the method, the perfect maze generated randomly is used as a secret embedding carrier, the hidden position of secret information is not exposed in the secret embedding process, and the embedding and extracting processes completely depend on a secret key; and the anti-attack capability of the embedded secret information and the reliability of secret information recovery are improved through a perfect maze generation strategy and a secret key consistency check strategy.

Description

technical field [0001] The invention belongs to the intersecting field of information security and information hiding, and relates to a maze-generating information hiding and restoring method, equipment and a readable storage medium. Background technique [0002] Traditional modified embedding, such as embedding secret information by modifying pixel values ​​or frequency domain coefficients, such algorithms tend to leave traces of modification, making it difficult to resist the detection of steganographic analysis algorithms based on natural image statistical characteristics, and the algorithm improvement space is very limited . [0003] To overcome this problem, carrierless information hiding methods have been proposed. The typical method is search-based carrierless information hiding, which expresses secret information by searching suitable unmodified natural carriers. For example, Zhou Z L, 2015 (Zhou Z L, Sun H Y, Harit R, et al. Coverless image steganography without em...
