Abstract— Secure transmission of sensitive information has become increasingly important due to the rapid growth of digital communication systems. This project proposes a secure data communication approach that combines cryptography and steganography to enhance information protection. In the proposed system, the secret text message is first encrypted using the Advanced Encryption Standard (AES) algorithm to ensure confidentiality. The encryption key is further protected using the RSA public key cryptographic technique to enable secure key exchange between sender and receiver. After encryption, the ciphertext is embedded into a digital image using the Least Significant Bit (LSB) steganography method, allowing the message to remain hidden without significantly altering the visual quality of the image. At the receiver side, the hidden data is extracted from the stego image, the AES key is recovered using RSA decryption, and the original message is reconstructed through AES decryption. By integrating encryption with image-based data hiding, the proposed system provides multiple layers of security, ensuring confidentiality, integrity, and secure communication over open networks.
