A Comparative Study of Steganography & Cryptography

Today, the secure communication between two parties is not an easy task as considering the possible attacks & unintentional changes during communication over untrusted medium like Internet. Steganography and Cryptography are two popular ways of sending vital information in a secret way. Steganography is the art of hiding of a message within some format so that presence of hidden message is indistinguishable. Cryptography involves converting a message text into an unreadable ciphertext. One hides the existence of the message and the other distorts the message itself. Many powerful & robust technologies of steganography & cryptography are developed. This paper is an attempt to analyze the steganographic & cryptographic techniques.
