Metamorphic cryptography — A paradox between cryptography and steganography using dynamic encryption

摘要

Cryptography is the art of securing information by making sure that the secret can be understood only by the right person. Steganography is the process of sharing information in an undetectable way by making sure that nobody else can even detect the presence of a secret. If these two methods could be combined, it would provide a fool-proof security to information being communicated over a network. This paper fuses the two methods and a new technique — Metamorphic Cryptography is born. The message is transformed into a cipher image using a key, concealed into another image using Steganography by converting it into an intermediate text and finally transformed once again into an image. The proposed method thus achieves a high degree of security for information.
