Blockchain-Based Secure Evidence-Management Police Assistance System

Abstract

The distributed and decentralized property of Blockchain technologies is very much suitable for those applications where integrity, confidentiality and proper tracking of operations is at highest priority. In this chapter, a Blockchain-based secure evidence management system for tracking police complaints and forensic reports is proposed. The proposed system provides security and privacy preservation of important documents used as evidence in the police system. The proposed scheme provides a Ethereum-based DApp to track a police complaint starting from FIR to when the complaint gets resolved, and also to provide security to forensic reports as security, confidentiality and integrity are at the highest priority. The proposed application supports forensic investigation with authenticity, immutability, traceability, resilience and distributed trust between evidential entitles. Details of tracking police complaints, further investigation, forensic report preservation and analysis will be recorded in chains of block. The proposed system is validated through various experimental results for security, privacy and sensitivity of important documents used as evidence by a police department.
