Abstract

Proper investigation of digital evidence is of prime significance in cyber investigations. From the collection of evidence, its preservation, and its analysis, it is important to maintain its integrity in the legal system due to the involvement of different stakeholders like law enforcement agencies, digital analysts, and the judiciary. This review paper focuses on how blockchain technology can be used to collect evidence efficiently. In the present scenario, the manual logs of the chain of custody are used to ensure that the evidence remains confidential and transparent. It is accompanied by filling out the application forms and maintaining logs within the organization handling the evidence. Hence, it is important to ensure the validity, integrity, and verifiability of evidence as it moves through different hierarchical levels. There are certain issues associated with the current chain of custody, such as evidence loss, theft, tampering, and, even worse, evidence manipulation inside the system. To avoid this situation and to make the process coherent, this review paper aims to highlight the potential use of blockchain technology to preserve chain of custody. Although this scientific technology is mainly used to run cryptocurrencies, with careful consideration and application, this could play a key role in supporting and managing the chain of custody. It is a distributed database that keeps track of blocks. These blocks are collection of entries that keep growing continually and are secured from editing and manipulation by retaining the hash of the previous block in the chain. This is a decentralized technology that is not easily compromised in terms of security and therefore has the potential to solve our problem area. A future research agenda needs to be established, which lays the solid foundation for further studies on this evident emerging area.

区块链技术在法医案件工作中维护监管链的潜在适用性
在网络调查中,正确调查数字证据至关重要。从证据的收集、保存到分析,由于执法机构、数字分析师和司法机构等不同利益相关者的参与,在法律体系中保持证据的完整性非常重要。本综述文件重点介绍如何利用区块链技术高效收集证据。在当前情况下,监管链的人工日志用于确保证据的保密性和透明度。同时,还需要填写申请表,并在处理证据的组织内部维护日志。因此,必须确保证据在不同层级移动时的有效性、完整性和可验证性。目前的监管链存在一些问题,如证据丢失、被盗、被篡改,更有甚者,证据在系统内部被操纵。为了避免这种情况,并使整个过程连贯一致,本文旨在强调区块链技术在保存监管链方面的潜在用途。虽然这项科学技术主要用于运行加密货币,但经过仔细考虑和应用,它可以在支持和管理监管链方面发挥关键作用。它是一个记录区块的分布式数据库。这些区块是持续增长的条目的集合,通过保留链中前一个区块的哈希值来防止编辑和篡改。这是一种去中心化技术,在安全性方面不易受到损害,因此有可能解决我们的问题领域。我们需要制定未来的研究议程,为进一步研究这一明显的新兴领域奠定坚实的基础。
