Towards Open Standards for Systemic Complexity in Digital Forensics
Digital Forensics (DF) is critical for fact-checking across all digitally mediated processes. While Artificial Intelligence (AI) offers powerful automation, its use in DF introduces challenges like exponential complexity, potential for bias, and lack of transparency. This chapter argues for the development of open, human-readable standards to standardize logical processes, ensure data integrity, mitigate bias, and facilitate explainable and reproducible AI applications in DF, ultimately aiming to ascertain truth in legal, governance, and scientific inquiry.

Ubiquity in Digital Forensics
Digital Forensics (DF) involves identifying, gathering, storing, analyzing, and communicating digital evidence from electronic devices and computer systems. Its core capability relies on precise information acquisition and logical processing. Increasingly, DF is relevant across all fields of inquiry, from criminal investigations to scientific and technical analysis, as all processes are now mediated by digital technologies. DF techniques are used to reconstruct facts from digital scenarios and for physical evidence with digital records, and involve machine learning to automate logical analysis.
Systemic Complexity
With technology proliferation and widening applications, DF is expanding into a state of systemic complexity, characterized by multidimensional evolution and rapid reconfiguration of its boundaries. DF inevitably overlaps with Computer Science (CS) and Data Science (DS). Accurate and systematic data curation practices, including data management planning (DMP), are instrumental in ensuring data integrity, accessibility, and validity of findings. DF techniques like data extraction, pattern recognition, and anomaly detection are commonly used in both DF and data science.
Digital Forensics and Artificial Intelligence (AI)
AI significantly enhances DF by automating and accelerating exponentially repetitive tasks such as data acquisition, processing, and analysis. AI-powered tools leverage machine learning for data recovery, analysis, and exposing registry information, including advanced techniques like data carving, steganography, and stochastic analysis. This supports detailed analysis of information lifecycles and hypothesis evaluation. However, the rapid automation can also amplify fallacies and errors if underlying logical processes are not standardized, transparent, explainable, and reproducible.
Open Challenges in DF
A major challenge is ensuring the validity, accuracy, and accountability of DF outcomes, especially with AI integration. Lack of transparency in ML processes can weaken scrutability and contribute to miscarriage of justice. Both human and AI judgments are susceptible to bias, particularly confirmation bias, and there are significant deficiencies in documentation. Challenges are categorized into technical (encryption, vast data), legal (jurisdiction, admissibility), personnel (lack of qualified staff), and operational (lack of standardized processes, audit trail trust).
Reasoning in DF
Reasoning is the cornerstone of DF, encompassing inductive, abductive, and deductive forms. Abduction is particularly important for generating new explanatory hypotheses. Experts combine these with diagrammatic, spatial-temporal, fuzzy, and probabilistic reasoning. Causal inference, the ability to establish cause-and-effect relationships, is a core DF capability. However, confounding factors—inherent statistical errors or deliberately fabricated data—pose significant challenges, with no known mechanisms to identify or address malicious confounding. Heuristic expert reasoning often relies on fuzzy causal inference for complex problems.
Towards Open Standards
Open standards are vital for ensuring consistent, interoperable, and transparent forensic practices, facilitating the reliable exchange of data and results among stakeholders. Currently, most DF standards are proprietary, with exceptions like DF XML for metadata. The adoption of open technical standards promotes transparency, interoperability, innovation, and reduces costs. The chapter proposes using Model Cards (MC)—declarative frames describing knowledge and processes—as a basis for human-readable open standards in AI for DF, enhancing transparency and auditability.

Case Study: Mitigating Miscarriage of Justice through AI Transparency
In numerous instances, the lack of transparency in automated digital forensics processes, exacerbated by inherent biases in AI algorithms and human interpretation, has contributed to significant miscarriages of justice. Cases have shown that blind trust in software-generated evidence, without standardized, human-readable audit trails, leads to wrongful convictions. The integration of explainable AI (XAI) and open standards is critical. By making data processing, logical reasoning, and AI decision-making transparent and auditable, we can prevent erroneous conclusions, uphold data integrity, and ensure fair legal and scientific outcomes. This proactive approach strengthens accountability and rebuilds trust in digital evidence.
