Biometric Technology in Forensic Investigations: Legal Standards and Challenges

Abstract

Biometric technology has rapidly advanced, offering unprecedented capabilities in forensic investigations through its ability to identify and verify individuals based on unique biological and behavioral traits. This paper explores the integration of biometric technology within forensic science, focusing on its application, legal standards, and the challenges that arise in criminal justice contexts. Biometric systems, including fingerprint recognition, facial recognition, iris scanning, and voice analysis, have demonstrated significant potential in solving crimes, improving evidence accuracy, and enhancing the efficiency of investigations. Forensic applications are scrutinized to reveal how biometric evidence is collected, processed, and presented in court. The discussion extends to the accuracy and error rates of different biometric systems, emphasizing the need for ongoing validation and calibration to maintain forensic credibility. Subsequently, the paper delves into the legal frameworks governing the use of biometric evidence. It addresses the balance between technological advancements and individual privacy rights, scrutinizing relevant legislation and case law. The analysis includes a review of standards set by regulatory bodies and the challenges of ensuring compliance with privacy laws while leveraging biometric data for investigative purposes. The final section focuses on the challenges faced by forensic practitioners and the legal system in integrating biometric technology. Issues such as data security, the potential for misuse, and the need for standardized protocols are discussed. Additionally, the paper explores the implications of false positives/negatives and the ethical considerations surrounding the use of biometric evidence in legal contexts.
