Abstract
Reversible data hiding is widely recognized as one of the most employed methods for copyright protection and data security. This technique involves embedding a unique piece of information, referred to as a watermark or secret data, without being detected by human or machine visual systems. Moreover, the original image is completely restored after embedded information is extracted by the recipient. Reversible data hiding technique has many vital applications, such as camouflage in communication to protect confidential information or embedding information into photos to protect digital image content. However, the problem with this technique is to maintain a good trade-off between imperceptibility and a higher bit embedding rate. This research provides a thorough review of existing methods of image steganography. Moreover, the paper also discusses the strategy to select different cover media for numerous applications in modern life.
