Steganography is derived from the Greek word steganos which literally means \"Covered\" and graphy means \"Writing\", i.e. covered writing. Steganography refers to the science of \"Invisible\" communication. For hiding secret information in various file formats, there exists a large variety of steganographic techniques some are more complex than others and all of them have respective strong and weak points. The Least Significant Bit (LSB) embedding technique suggests that data can be hidden in the least significant bits of the cover image and the human eye would be unable to notice the hidden image in the cover file.
