Steganography is the science that involves communicating secret data in an appropriate multimedia carrier, e.g., image, audio, and video files. The main goal of steganography is to ensure that the transmitted message is completely masked, thereby ensuring that the message is accessible only to the intended receiver and not to any intruders or unauthorized parties. In steganography, rather than robustness, the ultimate goal is to hide a message into a cover signal in such a way that an adversary is not even able to understand if the signal contains a hidden message or not. Due to the possible malicious uses of steganography and to the necessity of rigorously assessing the undetectability of the hidden message, steganography is always paralleled by steganalysis, i.e., the set of techniques that an adversary may use to discover the presence of the hidden signal. This review paper discusses about the recent steganography techniques along with their strengths and weaknesses.
