Blockchain-Based Secure Criminal Evidence Management System Using Smart ContractsID: 3679 Abstract :The Criminal Evidence Management System Using Blockchain Is Designed To Provide A Secure, Transparent, And Tamper-resistant Platform For Managing Digital Criminal Evidence Throughout Its Lifecycle. Traditional Evidence Management Systems Rely On Centralized Databases, Making Them Vulnerable To Unauthorized Access, Data Manipulation, And Single Points Of Failure. Such Limitations Can Compromise The Integrity Of Evidence And Weaken The Chain Of Custody During Legal Proceedings. To Address These Challenges, The Proposed System Leverages Blockchain Technology To Ensure The Authenticity, Immutability, And Traceability Of Digital Evidence. The System Employs Ethereum Blockchain And Solidity Smart Contracts To Securely Record Evidence-related Transactions, While Python, Django, And Web3 Facilitate Seamless Interaction Between Users And The Blockchain Network. Role-based Access Control Enables Administrators And Investigating Officers To Perform Authorized Operations Such As Evidence Submission, Retrieval, And Verification. Every Transaction Is Permanently Recorded On The Blockchain, Creating An Auditable History That Enhances Accountability And Prevents Unauthorized Modifications. The Proposed Solution Improves The Reliability And Efficiency Of Evidence Management By Eliminating The Risks Associated With Centralized Storage And Manual Record-keeping. Through Secure Storage, Transparent Access, And Automated Verification, The System Strengthens The Chain Of Custody, Increases Trust Among Law Enforcement Agencies, And Supports The Admissibility Of Digital Evidence In Judicial Processes, Making It A Robust Solution For Modern Forensic Investigations. |
