Review: Digital image steganography: Survey and analysis of current methods

摘要: Steganography is the science that involves communicating secret data in an appropriate multimedia carrier, e.g., image, audio, and video files. It comes under assumption if feature visible, point of attack evident, thus goal here always to conceal very existence embedded data. has various useful applications. However, like any other it can be used for ill intentions. been propelled forefront current security techniques by remarkable growth computational power, increase awareness by, individuals, groups, agencies, government through intellectual pursuit. Steganography's ultimate objectives, which are undetectability, robustness (resistance image processing methods compression) capacity hidden data, main factors separate from related such as watermarking cryptography. This paper provides a state-of-the-art review analysis different existing steganography along with some common standards guidelines drawn literature. concludes recommendations advocates object-oriented embedding mechanism. Steganalysis, attacking steganography, not focus this survey but nonetheless will briefly discussed.
