Abstract

A new technique proposed with the combination of cryptography and steganography enhanced with new secure feature for generating a new security system. Cryptography and Steganography are two popular ways for secure data transmission in which the former distorts a message so it cannot be understood and another hides a message so it cannot be seen. In cryptography, this system is used advanced encryption standard (AES) algorithm to encrypt secret message and then these are separated keys; one of which is used to hide in cover image. In steganography, a part of encrypted message as a key is used to hide in discrete cosine transform (DCT) of an image which is highly secured. This kind of system is to be introduced in applications such as transferring secret data that can be authentication of various fields.
