LLM让数字取证自动化,提升效率与准确性。

Digital Forensics in the Age of Large Language Models

  • 用大模型自动分析数字证据,替代人工繁琐操作。
  • 可处理复杂数据,提升取证效率和判案支持力。
  • 适合法证人员、安全研究者,也需关注伦理风险。

数字取证在现代调查中至关重要,依赖专业方法系统收集、分析和解释数字证据以支持司法程序。然而,传统技术高度依赖人工,面对数据量激增与复杂性提升已显不足。大型语言模型(LLMs)应运而生,显著提升了取证任务的自动化与智能化水平,正在重塑该领域。尽管取得进展,实务工作者普遍对LLM的能力、原理及局限性认知不足,制约其潜力发挥。本文旨在提供一个清晰、系统的综述,涵盖数字取证基础概念与LLM演进历程,强调其在文本理解、模式识别等方面的卓越能力。通过真实案例与场景分析,连接理论与实践。同时,批判性讨论当前挑战,包括幻觉、可解释性差、偏见及伦理问题。最后展望未来,呼吁推动透明、可问责、标准化的LLM应用,以保障司法公正与可靠性。

原文摘要 · Abstract (English)

Digital forensics plays a pivotal role in modern investigative processes, utilizing specialized methods to systematically collect, analyze, and interpret digital evidence for judicial proceedings. However, traditional digital forensic techniques are primarily based on manual labor-intensive processes, which become increasingly insufficient with the rapid growth and complexity of digital data. To this end, Large Language Models (LLMs) have emerged as powerful tools capable of automating and enhancing various digital forensic tasks, significantly transforming the field. Despite the strides made, general practitioners and forensic experts often lack a comprehensive understanding of the capabilities, principles, and limitations of LLM, which limits the full potential of LLM in forensic applications. To fill this gap, this paper aims to provide an accessible and systematic overview of how LLM has revolutionized the digital forensics approach. Specifically, it takes a look at the basic concepts of digital forensics, as well as the evolution of LLM, and emphasizes the superior capabilities of LLM. To connect theory and practice, relevant examples and real-world scenarios are discussed. We also critically analyze the current limitations of applying LLMs to digital forensics, including issues related to illusion, interpretability, bias, and ethical considerations. In addition, this paper outlines the prospects for future research, highlighting the need for effective use of LLMs for transparency, accountability, and robust standardization in the forensic process.
