Blockchain-Based Chain of Custody Evidence Management System for Digital Forensic Investigations

The demand for digital evidence is increasing worldwide. A reliable digital evidence management system is needed to ensure that justice is served in court. The chain of custody plays a vital role in this process, but people are the weakest link in any trust chain. Blockchain technology can be used to store and analyze digital evidence data in a secure and confidential manner, with proper access control. As digital evidence comes in various forms, blockchain can be dynamically changed to accommodate new data extraction methods. This research paper proposes and develops a blockchain-based digital evidence management system using Hyperledger Fabric.
