Drone forensics in law enforcement: Assessing utilisation, challenges, and emerging necessities

The proliferation of drone technology has introduced new challenges and opportunities for law enforcement, necessitating the development of drone forensics as a specialised field within digital forensics. This survey paper explores the critical role of drone forensics in modern policing, focusing on its applications in investigating crimes involving unmanned aerial vehicles (UAVs) and addressing emerging security threats. This paper examines the tools, data extraction methods, and operational practices employed in drone forensic investigations, with particular attention to cases of unauthorised surveillance, smuggling, and cyber-attacks. Furthermore, this study discusses the technical, legal, and ethical challenges associated with drone forensics, including encryption, anti-forensic techniques, proprietary software, and privacy concerns. Through a synthesis of current practices, technological advancements, and relevant case studies, this survey provides insights into the effectiveness, limitations, and evolving needs of drone forensics. Recommendations are offered to enhance law enforcement capabilities, emphasising the importance of continuous training, standardised protocols, and collaboration across agencies. This survey paper aims to support policymakers, law enforcement agencies, and forensic practitioners in integrating drone forensics as a versatile and effective approach for safeguarding public safety and ensuring justice in an increasingly drone-integrated world.
