Research on LSB-based Digital Image Information Camouflage Algorithm

摘要

Considering the security problem of LSB-based information camouflage, this paper analyzes and verifies the effect of different bit planes on the effect of hidden information, and aiming at the characteristics of large data volume and high redundancy, the last-two random embedding method is proposed to camouflage information, which improves the LSB algorithm. The concealment amount of information camouflage is increased in practice. For different information embedding methods, this paper analyzes and verifies the information camouflage algorithm based on improved LSB have a greater amount of information hiding while ensuring security.
