Robust and Secure Evidence Management in Digital Forensics Investigations Using Blockchain Technology

Abstract

The chapter proposes a framework for evidence management in digital forensic investigations that leverages blockchain technology to ensure integrity and authenticity of the chain of custody process. The framework utilizes smart contracts, nodes, and consensus algorithms to create a tamper-proof record of the entire chain of custody process from evidence collection to presentation. A contract that facilitates transfer of ownership of the forensic report from the forensic laboratory to the investigation department is implemented. Using this approach, the authors ensure integrity and security of the forensic report, thereby mitigating any potential risks of tampering or compromise through unethical means. A robust framework to safeguard credibility of forensic report to maintain the chain of custody, instilling confidence in the reliability of the investigative process is established. Traditional methods of evidence management, showing that the proposed framework offers a secure, reliable, and transparent solution for managing digital evidence in digital forensics investigations has been proved.
