CRIMINAL EVIDENCE MANAGEMENT SYSTEM USING BLOCKCHAIN

Abstract

To expedite the lifetime of digital forensic evidence while guaranteeing its security and validity, the study proposes a
Decentralized Evidence Management System that utilizes distributed storage and blockchain technology. The court
proceedings may be impacted by this version's solutions to issues with evidence tracking, unlawful access, and manipulation.
It uses IPFS, leverages a two-tier blockchain architecture to separate static and dynamic data, and permits off-chain data
storage. Smart contracts improve auditability and chain of custody in many ways, one of which is automating access control.
Secure interfaces are available for anybody involved with the legal and police systems, and the design is resistant to
manipulation. This approach improves the processing of digital evidence by increasing trust, accountability, and openness;
hence, it is a safe and effective solution to handle the present problems in digital forensics.
