AI-Assisted Image Encryption and Decryption System

Overview

This project focuses on securing digital images through encryption and decryption techniques that combine mathematical logic with Artificial Intelligence.
The system takes an image uploaded by a user, encrypts it using AES (Advanced Encryption Standard), and generates a secret key. This key is then used to decrypt the image back to its original form.

The project highlights collaboration between Mathematics and Computer Science/AI — mathematics ensures the strength of encryption through finite field algebra and entropy analysis, while AI helps optimize the key generation process for improved randomness and security.

The work demonstrates how mathematical models and AI algorithms can work together to protect sensitive visual data in real-world applications such as digital communication, healthcare, and defense.
