Digital communication has become an essential part of infrastructure nowadays, a lot of applications are Internet-based and it is important that communication be made secret. As a result, the security of information passed over an open channel has become a fundamental issue and therefore, the confidentiality and data integrity are required to protect against unauthorized access and use. This has resulted in an unstable growth in the field of information hiding. Stegnography is a popular method to provide security. Steganography is the science that involves communicating secret data in an appropriate multimedia carrier, e. g. , image, audio and video files. It comes under the assumption that if the feature is visible, the point of attack is evident, thus the goal here is always to conceal the very existence of the embedded data. For hiding secret data in digital media, large varieties of steganographic techniques are available, some are more complex than others, and all of them have their respective pros and cons. This paper intends to give thorough understanding and evolution of different existing digital media steganography techniques of data hiding. It covers and integrates recent research work.
