This paper introduces a fresh take on keeping files safe in the cloud. We've designed a system that combines QR codes for a multi-party authentication process with an encryption method boosted by random noise. Built with a user-friendly Streamlit web interface and a dependable PostgreSQL database, our system uses ChaCha20 encryption, made even stronger by adding noise images that act as extra security keys. When someone uploads a file, it's locked up tight with a key created from three unique strings--one for the user, one for an admin, and one for a token. These strings are turned into QR codes and shared among different people, so you need all three to unlock the file. Our thorough testing shows that this setup is fast, can grow with demand, and stands up well to all sorts of attacks, even those that might come from quantum computers down the road. By mixing in noise to make encryption trickier to crack, we've crafted a practical, future-ready way to secure cloud storage.
