In the traditional methods of information hiding, confidential information is embedded in the carriers by modifying carriers’ parameter characteristics, that will certainly leave traces of adjustments on the carriers. These adjustments are usually too small to be discerned by the human eye, but they can be discovered by some steganalysis algorithms and therefore, safety cannot be guaranteed using these methods. This challenge can be solved completely through a new technique called coverless steganography. This method does not need to employ a cover for the purpose of hiding, as well as no traces of modifications occur in the cover by hiding the secret message. In this method, multiple covers are chosen so that these covers contain the characteristics of the message to be hidden, then they are considered as container covers for the secret message and are sent to the recipient for the purpose of extracting the secret message. Therefore, coverless steganography methods have higher security than traditional methods of information hiding. In this study, more than 30 papers are included to provide an extensive explanation of this field as well as cover the main aspects of a coverless information hiding method to hide the confidential information in the video cover.
