LSB Hiding : Advanced encryption standard (AES) that has been

proposed by National Institute of Standards and Technology

(NIST) plays a significant role of a secure algorithm for

data exchanged. Two prime processes involved: encryption

(cipher) and decryption (decipher). Cipher is a process

to convert data into unintelligent form called ciphertext.

Similarly decipher is a process for the data to be converted

back into its original form called paintext.
