| Summary: | The frequent and intensive transmission of information on the internet
requires protection techniques to secure sensitive information. Steganography is one of
many security techniques that consist of concealing information inside an appropriate
multimedia (e.g. image, video, audio…etc.) with the objective to hide the embedded
information. Many challenges confront steganography systems like capacity (size of data
embedded) and imperceptibility (level of undetectability). These two aspects are
inversely proportional to each other which produces a data hiding dilemma. This paper
presents a review of the steganography methods used in recent years and a critical
analysis based mainly on capacity measurement and, secondly, on imperceptibility
measurement and steganography domain. |
