Abstract:

In the era of modern technology, there is a need of safe and secure communication. The art of impregnable communication through a safe medium like images is known as steganography. The process that detects the embedded data in the medium is called as Steganalysis. In this review paper, we have studied various methodologies proposed by the researchers in the field of steganography. The main objective of image steganography is to hide the existence of data from unauthorized action. Image steganography is a technique that provides a safe way to the secret embedded data to the target user. To hide the secret data in the images various techniques are proposed by the researchers, some are complex and other produce good results. Each methodology has good and bad points, so techniques are compared as well.
