Secure Data Hiding in Image: Protecting Your Confidential Information

A web-based application for securely encrypting and decrypting messages hidden within images, ensuring your sensitive data remains private and protected.

🖼️ Preview

📑 Project Presentation

For a detailed overview of the project, you can refer to the project presentation:

AICTE x IBM-INTERN-PROJECT-PPT.pptx

🚀 Features

• Encrypt Message: Hide your secret messages within images using a secure encryption password.
• Decrypt Message: Retrieve hidden messages from images by providing the correct decryption password.
• Password Protection: Incorrect passwords generate random characters and symbols, safeguarding your data.

🛠 Tech Stack

Frontend

• HTML, CSS (Tailwind CSS), TypeScript
• React (for building user interfaces)
• Vite (for fast development and build tooling)

Backend

• Python (Flask for server-side operations)
• Pillow (Python Imaging Library for image processing)
• Cryptography (Python library for encryption and decryption)
