Assisting Police and Evidence Protection with Block chain

Abstract

A The increasing digitization of law enforcement processes has heightened the need for secure and tamper-proof evidence management systems. Traditional evidence handling methods suffer from risks such as data manipulation, unauthorized access, and storage failures, which threaten the integrity of the justice process. This project introduces a blockchain-based solution for digital evidence protection, offering a decentralized and transparent mechanism that ensures traceability and immutability of data from the point of collection to its presentation in court. By integrating cloud storage and blockchain technologies, the system enhances evidence security, facilitates real-time updates, and enables strict access controls through smart contracts and cryptographic protocols. Our proposed solution not only addresses the critical drawbacks of current manual and centralized systems but also streamlines investigative workflows and fosters trust in digital legal processes. Key features include user authentication, hash-based integrity verification, blockchain logging of metadata, and comprehensive monitoring of all interactions with evidence files. The architecture is modular, supporting seamless integration with law enforcement IT systems and offering scalability for cross-agency collaboration. This innovation is a significant step toward digitized, tamper-proof, and legally robust evidence handling.
