The Pi I was running the backend on decided to retire early 🥲 A new one is on the way, so things will be back up and running once it lands! You can still read about framework in meanwhile :)

📄 A glimpse behind the research.
As a part of my undergraduate program, I published a research paper titled “A Blockchain-Based Private Framework for Facilitating Digital Forensics Using IoT”. The paper explores a novel way of leveraging blockchain to preserve the integrity of digital evidence in real-time, especially from resource-constrained IoT environments.
The idea of the paper is to:
🛠️ The Framework
This app is supposed to be a demo of the framework presented in the paper. The frontend acts as an access point, allowing users to upload an image, encrypt it, store it on a privately hosted blockchain network, and retrieve it using its hash.
How it works:
🔍 Retrieve Encrypted Image
🧠 My Contribution
Beyond leading the team, I developed the core logic, security and encrypting mechanism, and the architecture powering the proposed framework. The goal was to create a way to store digital evidence in a way that makes it tamper-proof and immutable.
- Implemented SHA-256 based block hashing in Python.
- Used a mixed cipher encryption protocol to protect uploaded image data.
- Applied multi-step encryption unique to each node to prevent man in the middle attacks.
- Designed the block structure to include metadata like timestamp and previous hash.
- Built a simple yet functional chain validation mechanism.
- Used VPNs to create a private network isolated from the public internet.
