DNA Based Steganography

Overview

This work introduces a novel secure communication paradigm that integrates steganography and cryptography to achieve four levels of security. The proposed approach ensures that a steg-analyst cannot decipher the hidden text without a secret key to decrypt the ciphertext. The methodology leverages steganography to conceal the existence of communication and cryptography to alter the content of the message, ensuring data security in modern communication networks. Given the open nature of the internet and its susceptibility to data manipulation and deception, the proposed system addresses the critical need for secure communication and encryption strategies, especially in sensitive applications.

Approach

The proposed system combines steganography and cryptography to enhance security:

Encryption: Sensitive data is first encrypted, converting it into an unreadable format. Cryptography serves as the first layer of protection by transforming plaintext into ciphertext, making the content unintelligible without the appropriate decryption key.
Steganography: The encrypted data (ciphertext) is embedded within an image file, effectively concealing the existence of the communication. This layer ensures that even if the file is intercepted, the hidden message remains undetected.
Integration and Innovation: By integrating these two methods, the framework offers a robust solution against potential security threats. The use of least significant bit (LSB) steganography provides a subtle and efficient means to embed the ciphertext in image files, creating a multi-layered security mechanism.
Future Enhancements: The system is adaptable for diverse applications such as military, business, anti-crime, and trade. Future improvements may involve replacing LSB with more advanced steganographic techniques and incorporating additional cryptographic algorithms to further strengthen the security framework
