Securing Forensic Evidence using Blockchain

In today’s digital era, the protection and management of data have become essential across all fields. With the increasing risks of tampering and cyberattacks, ensuring the security and authenticity of sensitive information is critical, especially for forensic evidence. Cybercriminals often attempt to alter crucial data, threatening the reliability needed for legal investigations. To address these challenges, it is vital to maintain the integrity and traceability of forensic evidence as it moves through various stakeholders, including pathology labs, hospitals, and law enforcement agencies. Blockchain technology provides an ideal solution by offering a decentralized, transparent, and immutable system for managing forensic evidence. This paper proposes a blockchain based framework for securely handling forensic reports, implemented on the Ethereum platform. By leveraging smart contracts and cryptographic methods, the system ensures evidence integrity, making tampering easily detectable at any stage in the chain of custody.
