An improved steganography model for efficient data integrity and confidentiality

Abstract

In the contemporary era, ensuring secure and confidential data transmission poses a significant challenge, especially in the realm of networking. This paper presents a methodology aimed at bolstering data integrity and confidentiality by extending existing steganography techniques and leveraging encryption and decryption methods such as AES128, SHA256, and Image Steganography Cryptographic Methods. The proposed approach entails combining encrypted plain text and a hash code within an image to secure data before transmission to the end-user. In the event of an attack, even if successful, the attacker would only gain access to a RAW message without knowledge of the plain text. This insight opens avenues for further advancements in various research areas.
