Metamorphic Cryptography Using AES and LSB Method

Now a days, internet users has led to the significant growth of cyber attack incidents. Therefore, it is essential to secure sensitive data before transmission to guarantee the secrecy of information and prevent unauthorized data alteration or loss. This issue can be solved using cryptography and steganography techniques. This paper uses an LSB-based image steganography algorithm to hide the message. Before being put into the cover image, the secret message is encrypted using the AES cryptographic algorithm while the secret message can be a text string, pdf, image, audio, or video. As a result, only the authorized user with the decryption key can extract the actual message from the stego object. Thus, it is still challenging to get the secret message when an attacker discovers the message. It uses Python version 3.9.10 to implement the proposed algorithm.
