Exploring Blockchain Technology for Chain of Custody Control in Physical Evidence: A Systematic Literature Review

Abstract

Blockchain technology, initially known for its applications in the financial industry, has emerged as a promising solution for various other domains. One prominent area for the use of blockchain-based solutions is forensics, specifically the chain of custody maintenance and control. While there have been numerous research projects exploring the use of blockchain technology in digital forensics, limited attention has been given to its application in controlling of the physical evidence chain of custody. In this research, we aim to explore the literature on the use of blockchain technology to solve problems related to the physical evidence chain of custody. Through a systematic literature review (SLR), we analyzed 26 resources discussing blockchain-based solutions for evidence chain of custody issues, based on requirements that could be applied to both physical and digital evidence. The results showed that there is a lack of studies involving the use of blockchain technology to solve problems related to the physical evidence chain of custody, and future research should focus on solving the issue.

Digital Gold or Digital Security? Unravelling the Legal Fabric of Decentralised Digital Assets

“…Since then, the number and types of decentralized digital assets (DDAs) has exploded [2]. This expansion of the asset class was facilitated by the advent of smart contract capable chains that can support a variety of functions [3][4][5][6][7][8], governance tokens, and the creation of decentralized finance (DeFi) [9]. As a small asset class and associated industry, DDAs have been largely unregulated aside from the application of securities laws to initial coin offerings (ICOs) that were prominent around 2017 [10,11].…”
