The relevance of biometric technology in investigating terrorist crimes is increasing due to the rise in global security threats and the need to enhance law enforcement effectiveness. The main goal of this article is to analyze the application of biometric technologies for improving the effectiveness of detecting and apprehending terrorists across different regions of the world. The research methodology includes statistical data analysis, calculation of weighted averages, and scenario forecasting concerning terrorist attacks. The study identifies key factors associated with biometrics, including facial recognition, fingerprint analysis, and retinal scanning technologies, and outlines their potential impact on increasing crime-solving rates. The results show that the use of biometric systems significantly reduces the number of unsolved terrorist crimes, enhances law enforcement coordination, and aids in early threat prevention. The article discusses various challenges countries face in solving crimes, such as underdeveloped infrastructure and inadequate adoption of modern technologies. The practical significance of the study lies in providing recommendations to improve international cooperation and further implement biometric technologies to ensure global security. Future research should focus on exploring new ways of integrating biometric technologies into law enforcement systems and adapting them to evolving threats.
