The integration of machine learning (ML) and computer vision technologies into biomechanics has opened new possibilities for forensic applications. By leveraging these advancements, critical biomechanical parameters like three-dimensional body shapes, anthropometrics, and kinematics can be estimated from simple single-camera images or videos. This is particularly valuable in forensic scenarios, where traditional methods requiring complex multi-sensor systems or specialized equipment are often impractical.
For example, in accident reconstructions, where biomechanical analysis serves as evidence in legal proceedings, the only available data may be a single piece of footage. AI-driven tools, such as pose estimation algorithms (Blazepose, ICON, MeTRAbs) and three-dimensional body shape reconstruction models (PIFuHd), can extract detailed biomechanical data from such limited inputs, enabling accurate analysis of spinal kinematics and segmental mass estimations.5
AI also aids in analyzing complex biomechanical events, such as whiplash injuries in car accidents or workplace lifting incidents, by reconstructing body movements and estimating external loads. These data-driven insights enhance the objectivity and reliability of forensic investigations, strengthening the evidence presented in court. However, challenges remain, including ensuring prediction accuracy, accounting for complex human interactions, and refining load estimation techniques.
Despite these hurdles, AI’s role in forensic biomechanics is expanding. By integrating traditional musculoskeletal modeling with ML and computer vision, AI is making biomechanical analysis more accessible, efficient, and reliable—paving the way for broader applications in forensic science.5
Digital Forensics: AI vs. Cybercriminals
AI, including ML and deep learning (DL), along with automation, is revolutionizing digital forensics by improving efficiency, accuracy, and cost-effectiveness.
Digital forensics involves the scientific identification, collection, examination, and analysis of digital data while ensuring a strict chain of custody and preserving data integrity. With cybercrimes such as hacking, data breaches, malware attacks, and phishing scams on the rise, advanced forensic tools have become essential.
The annual cost of cybercrime now exceeds $2 trillion, prompting organizations to increase investments in detection and prevention. Traditional forensic methods, which require manually sorting through vast amounts of data, are both time-consuming and resource-intensive. AI and automation help overcome these limitations by enabling faster, more precise analysis of digital evidence—even in non-cyber crimes where key evidence is stored on devices like cell phones and computers.6
AI-powered ML and DL algorithms can process extensive datasets, identify patterns, and generate insights with minimal human intervention. ML models use both supervised and unsupervised learning to analyze past data and detect anomalies, while DL leverages artificial neural networks (ANNs) to process complex data types, such as images, audio, and text. These AI-driven tools automate tasks like data extraction, analysis, and decision-making, reducing human error and improving the scalability of forensic investigations.
When combined with automation, AI creates intelligent systems capable of autonomously performing forensic tasks, such as detecting malicious network activity or tracing fraudulent financial transactions. Real-world applications, such as Intrusion Prevention Systems (IPS), demonstrate how AI-driven automation can proactively identify and mitigate cyber threats. As AI continues to advance, its role in digital forensics will only expand, making forensic investigations more efficient and reliable.6
AI and Facial Recognition: A Double-Edged Sword
Facial recognition, a key application of AI-driven biometrics, has evolved from early human identification based on facial features to modern automated systems powered by artificial intelligence. Historically, people relied on visual cues such as forehead shape, nose structure, and unique markings like freckles or birthmarks to distinguish individuals.
Today, these characteristics are digitized and analyzed by automated facial recognition systems (AFRS), which compare facial features in images and videos to identify individuals. This technology is widely used in applications such as smartphone unlocking, locating missing persons, and tracking attendance in workplaces and schools.7,8
Facial recognition systems operate by scanning facial features and converting them into a mathematical representation called a faceprint. This faceprint is then matched against a database of stored images. Deep learning algorithms, primarily convolutional neural networks (CNNs), power this process by analyzing key facial landmarks—such as the distance between the eyes, jawline shape, and nose structure—to create a unique biometric profile.
For example, India’s National Crime Records Bureau (NCRB) has proposed using AFRS to identify criminals, recognize unidentified corpses, and integrate with existing databases, such as CCTV footage, for criminal investigations.7,8
Despite its potential, facial recognition technology faces significant challenges. Privacy concerns and algorithmic bias raise ethical questions, particularly regarding fairness and discrimination. Studies have also shown that facial recognition systems can have higher error rates for certain demographic groups, leading to concerns about bias and reliability. Additionally, the lack of comprehensive legislation complicates its regulation. Countries like the United States, the United Kingdom, and Australia are struggling to balance public safety benefits with the need to protect individual privacy.7,8
DNA and Genetic Forensics: AI Unlocking Hidden Clues
AI is increasingly being applied to DNA and genetic forensics, offering significant advancements in the analysis and interpretation of genetic data. The two primary applications of AI are haplogroup analysis and short tandem repeat (STR) profile analysis. In haplogroup analysis, AI algorithms classify DNA samples into specific genetic groups, enhancing the speed and accuracy of the classification process. For STR profiles, AI reduces the risk of misinterpretation by automating the analysis of complex genetic data, leading to more precise individual identification.9
AI tools, such as ML and ANN, are particularly effective at processing large datasets and uncovering patterns that traditional methods might overlook. For example, ANNs have been used to predict age based on DNA methylation patterns, outperforming traditional regression models. AI also aids in analyzing biological data, including DNA, RNA, and epigenetic markers—essential for distinguishing human evidence from non-human samples in forensic investigations.9
Ethical Dilemmas: Can We Trust AI in Forensics?
With great power comes great responsibility, and AI in forensics is no exception.
AI-driven forensic tools raise significant ethical concerns, including the potential for bias amplification due to non-diverse datasets, privacy risks associated with biometric data collection, and opaque decision-making processes that can undermine trust. Ensuring fairness requires diverse training data, clear regulations, and AI systems that offer transparency and interpretability.
Legal standards must evolve to address the reliability and admissibility of AI-generated evidence, ensuring that it meets rigorous forensic requirements. At the same time, overreliance on AI could sideline human expertise, raising concerns about accountability and the role of forensic professionals in investigations. Additionally, disparities in access to AI tools between well-funded and underfunded agencies create ethical and practical challenges, potentially widening gaps in forensic capabilities.10
As AI continues to shape forensic science, balancing innovation with ethical safeguards will be essential to maintaining public trust and ensuring justice.
What’s Next for AI in Forensic Science?

One of the most promising advancements is in crime scene analysis, where AI is expected to evolve from passive data processing to real-time, autonomous forensic assessments. Smart drones and robotic investigators equipped with AI-driven sensors could soon collect and analyze evidence on-site, reducing the time and human effort required for forensic examinations.
AI-powered 3D reconstructions will integrate data from digital devices, security footage, and environmental sensors, creating highly detailed, dynamic visualizations of crime scenes. Future AI systems may even be capable of synthesizing information from multiple sources—videos, audio recordings, and physiological responses—to provide a more complete, data-driven understanding of events.
In forensic DNA analysis, AI will push the boundaries of genetic profiling, making it possible to extract meaningful information from even the most degraded or complex DNA samples. Advances in AI-driven forensic sequencing could allow for rapid, near-instantaneous DNA matching, reducing backlog delays and improving accuracy in cold cases.
As AI enhances the ability to predict phenotypic traits from genetic markers, forensic investigations may soon incorporate advanced predictive modeling to generate composite sketches based solely on DNA, a development that brings both investigative potential and ethical considerations. AI-powered ancestry tracing will also become more refined, improving the ability to link unidentified remains to missing persons or criminal suspects with unprecedented precision.
Predictive analytics will also play a larger role in forensic science, moving beyond crime hotspot identification toward proactive crime deterrence. Machine learning models trained on behavioral patterns, financial transactions, and social network activity could help law enforcement anticipate criminal activity before it occurs.
While these advancements promise to improve public safety, they also raise concerns about privacy, bias, and accountability. Addressing these challenges will require the development of transparent AI auditing frameworks, as well as legal and ethical guidelines to govern how predictive models are used in investigations.
As AI-generated evidence becomes more common in courtrooms, explainability and reliability will be critical. The forensic community will need to ensure that AI tools provide clear, interpretable results that meet evidentiary standards. AI may eventually play an active role in legal proceedings, not only assisting forensic experts but also shaping how evidence is presented and understood in trials. Ensuring fairness in AI-driven forensic science will require interdisciplinary collaboration between forensic scientists, legal professionals, and AI researchers, along with continuous efforts to mitigate biases in algorithmic decision-making.
With these advancements, forensic science is on the brink of a transformation that could improve investigative accuracy, expedite case resolutions, and enhance overall efficiency. However, the success of AI in this field will ultimately depend on how well ethical, legal, and privacy concerns are addressed.
Preparing forensic professionals for this shift will be essential, requiring ongoing education in AI ethics, digital evidence handling, and algorithmic bias detection. If implemented responsibly, AI has the potential to not only revolutionize forensic science but also strengthen the integrity of criminal investigations and contribute to a more just and secure society.11,12
