The two popular methods of transmitting secret information in very secured way are Cryptography and Steganography. Cryptography scrambles information so it can't be comprehended while the Steganography shrouds the message so that it can't be visible. In this method, first a message is encrypted using an algorithm based on AES cryptographic algorithm or Horse step algorithm which is then embed inside an image using method of Least Significant Bit (LSB) substitution. Digital pictures usually have an oversized quantity of redundant information, thus it's attainable to cover message within image file.Image steganography deals with exploiting restricted power of the human vision where message is hiddenwithinLSB of the image data. This embedding technique relies on the very fact that the LSB bit in an image will be thought of as random noise, and consequently they turn out to be less receptive to any change on the image.Cryptography and Steganography combinedly can enhance the protection of the info embedded. This combinable methodology can satisfy the wants like capability, security and hardiness for secure knowledge transmission over an open channel.
