Introduction

This past month, I had the incredible opportunity to intern at the National Crime Records Bureau (NCRB). During my time there, I delved into the fascinating world of fingerprint science and its evolution. In this blog, I'll share my experiences and the knowledge I gained, covering the history of fingerprint science, legal frameworks, international collaborations, advanced forensic technologies, and my practical exposure at NCRB.

Discovering the History of Fingerprint Science

My internship kicked off with a deep dive into the rich history of fingerprint science. I explored its global development and key milestones in India. Learning about pioneers like Hemchandra Bose and Azizul Hoque, who significantly influenced this field, was truly inspiring. I also discovered the first documented case solved using fingerprints by Francis Roger and the pivotal Kangali Charan case in India.

Understanding the Legal Framework

An essential part of my internship was understanding the legal framework surrounding fingerprint evidence. I studied the Indian Penal Code (IPC) and Section 293 of the Criminal Procedure Code (Cr.PC). Additionally, learning about the color codes used in Interpol reports highlighted the importance of standardized communication in international crime detection.

The Art of Fingerprint Charting

Fingerprint charting is a meticulous process, and I had the chance to master it during my internship. I learned the rules governing fingerprint charting, such as the direction of lines, the prohibition of line intersections, and drawing perpendicular lines from ridge characters. This precision is crucial in fingerprint analysis.

Exploring Various Law Enforcement Bureaus

I also gained an overview of various law enforcement agencies in India, including the Central Bureau of Investigation (CBI), National Investigation Agency (NIA), Enforcement Directorate (ED), Narcotics Control Bureau (NCB), and Wildlife Crime Control Bureau (WCCB). This provided valuable insights into their diverse roles and responsibilities in maintaining law and order.

Minimum Characteristics for Fingerprint Opinions

One intriguing aspect of my training was learning about the minimum characteristics required for forming fingerprint opinions in different countries. For instance, India requires a minimum of 08 characteristics, the USA requires 12, and Australia requires 18. This variation underscored the importance of understanding and adhering to different forensic standards globally.

The Innocence Project

I was also introduced to the Innocence Project, founded in 1992 by Barry C. Scheck and Peter J. Neufeld. This organization uses advancements in DNA testing to exonerate wrongfully convicted individuals. Their commitment to criminal justice reform was truly inspiring.

Advanced Tools: Cri-MAC and NAFIS

Exploring tools like Cri-MAC (Crime and Criminal Tracking Network & Systems) and the National Automated Fingerprint Identification System (NAFIS) equipped me with knowledge about advanced search mechanisms, database management, and the integration of biometric technologies in crime detection. These technologies are pivotal in modern investigative processes.

Getting to Know NAFIS

A significant portion of my internship was dedicated to understanding the intricacies of NAFIS. This comprehensive system includes features like live enrollment, chance print application, ten-print slip capture, and a mobile app for police personnel involved in traffic management. The National Fingerprint Number (NFN) system, with its unique 10-digit alphanumeric identification, ensures efficient categorization and retrieval of fingerprint records.

Hands-On Experience at NCRB Facilities

The practical experience at NCRB facilities was invaluable. At the Photography Lab, I saw how fingerprints are initially photographed for identification, providing insights into the early stages of forensic analysis. The Fingerprint Demo Lab showcased a range of fingerprint development instruments, from primitive to modern, illustrating the evolution of fingerprint identification technology. Visiting the Fingerprint Museum on the first day of my internship offered a historical perspective on the development of fingerprint science.

Conclusion

My internship at NCRB was a transformative experience. It deepened my understanding of fingerprint science, forensic technologies, and the collaborative efforts involved in ensuring justice and security. The exposure to cutting-edge tools, methodologies, and practical applications will undoubtedly shape my future endeavors in forensic science. I am grateful for the valuable learning opportunities provided by NCRB and look forward to applying this knowledge in my future career.
