🔍 Blockchain-Based Forensic Framework

📄 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 little 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:

Upload Image (Max: 1MB)

Encryption Key

🔍 Retrieve Encrypted Image

Hash

Decryption Key

🧠 My Contribution

Beyond writing the paper, I developed the core logic, security mechanism, and data structures powering this framework. The goal was to bridge theory and implementation for real-world impact.

Implemented SHA-256 based block hashing in Python
Used symmetric encryption to protect uploaded image data
Designed the block structure to include metadata like timestamp and previous hash
Built a simple yet functional chain validation mechanism
