Abstract

Steganography refers to data or a document hidden in a digital image, video or audio file. If a person perceives the files in which the data is stored inside, there will be no evidence that any information is concealed. So the person is not going to try to decrypt the data. Mostly, LSB encoding is used to encode the text in the image which is called as Image steganography. But image steganography is susceptible to pixel degrading techniques which allows attacker to degrade the image pixels and recover the secret message. This prototype will act as the secondary secure channel of transmission, when the key of AES encryption is compromised. In this paper, we have implemented the 256-bit AES encryption and image and audio steganography using LSB encoding and DWT. Audio files are less susceptible to attack. We also study the audio steganography with the cryptography method to accomplish the safety.
