Steganography is a means of data hiding in images for covert transmission. In recent years, steganography and steganalysis are two important areas of research that involve a number of applications.

Steganography is an art of embedding information in a cover image without causing statistically significant variations to the cover image. Steganalysis is the technology that attempts to defeat steganography by detecting the hidden information and extracting.
