Abstract: Information hiding technology can embed secret information into images, video, audio and other media. Authorized users can get embedded data from the medium of implicit data, so as to realize the transmission of information. Traditional information hiding only focuses on covert transmission, making it impossible for unauthorized persons to detect the existence of hidden information and does not require the carrier to remain undamaged after information extraction. But reversible data hiding technology can not only realize covert communication, but also realize lossless restoration of the original carrier image after extracting the hidden information, therefore, it has extremely important value in the field of high fidelity, This article systematically reviews the development of image reversible information hiding technology, Four methods of lossless compression, difference expansion, histogram shifting, and prediction-error expansion are introduced, the advantages and limitations of various methods were summarized, and a comparative analysis was conducted. The future development direction was discussed, providing new ideas for the future development of this technology.
