摘要
Internet brings us not only the convenience of communication but also some security risks,such as intercepting information and stealing information.Therefore,some important information needs to be hidden during communication.Steganography is the most common information hiding technology.This paper provides a literature review on digital image steganography.The existing steganography algorithms are classified into traditional algorithms and deep learning-based algorithms.Moreover,their advantages and weaknesses are pointed out.Finally,further research directions are discussed.
