A Novel Hybrid Image Synthesis-Mapping Framework for Steganography Without Embedding

The system integrates AES encryption with image steganography and fragile watermarking to ensure secure and tamper-evident communication. It encrypts plaintext messages using the AES algorithm and embeds the resulting cipher text into an image using the Least Significant Bit (LSB) technique. A dynamic fragile watermark is applied to the image to detect tampering. The receiver verifies the image's integrity by comparing the extracted watermark with the original. If the watermarks match, the system decrypts the message; if not, it generates a tampering report. This hybrid approach combines cryptography, image steganography, and watermarking to provide robust security and tamper detection.
