 Enhancing Security and Streamlining Processes with Biometrics

Biometrics has emerged as a groundbreaking solution in the realm of automated recognition, leveraging unique physical characteristics like fingerprints to identify individuals. The Department of Homeland Security (DHS) has harnessed the power of biometrics for a wide range of purposes, including detecting and preventing illegal entry into the United States, administering immigration benefits, facilitating legitimate travel and trade, enforcing federal laws, and verifying visa applications.

DHS entrusts the Office of Biometric Identity Management (OBIM) with the responsibility of providing biometric identification services to protect the nation. OBIM stands as the primary provider of biometric identity services within DHS and maintains the largest biometric repository across the U.S. government. Operating and maintaining the Automated Biometric Identification System (IDENT), OBIM currently houses an impressive database of approximately 300 million unique identities, processing over 400,000 biometric transactions on a daily basis.

To enhance the effectiveness of their efforts, DHS ensures biometric interoperability with the Department of Defense (DoD) and the Department of Justice (DoJ). By employing advanced data filtering techniques and stringent privacy controls, DHS shares critical biometric information with these entities to support their missions in homeland security, defense, and justice.

Enhancing Security and Streamlining Processes with Biometrics

Let's delve deeper into the history and applications of biometrics to understand their significant impact on various sectors:

Biometrics in History

Biometrics may seem like a recent innovation, but its foundations can be traced back hundreds and even thousands of years. The rapid urbanization during the industrial revolution in the mid-1800s led to an increased need for formal identification methods, consequently giving rise to the widespread adoption of biometrics. Today, biometric systems find application in law enforcement, commercial sectors, migration control, civil identification, healthcare, and more.


  • 1892: Sir Francis Galton develops the first fingerprint classification system.
  • 1903: New York state prisons begin using fingerprints for identification.
  • 1960: Face recognition takes a significant step towards automation through the research of Woodrow W. Bledsoe.
  • 1969: The Federal Bureau of Investigation (FBI) initiates efforts to automate fingerprint recognition.
  • 1994: The Immigration and Naturalization Service develops IDENT as a law enforcement tool for the U.S. Border Patrol, which by 1999 contained 1.8 million biometric identities.
  • 1999: The capture of Rafael Resendez-Ramirez, also known as "The Railroad Killer," prompts a review of IDENT and calls for integration with the FBI's fingerprint database. Resendez-Ramirez had multiple convictions and outstanding warrants, highlighting the need for improved biometric coordination.
  • 2011: The U.S. Department of Defense and the U.S. Department of Homeland Security signed a Memorandum of Understanding, laying the groundwork for interoperability between the DoD's Automated Biometric Identification System (ABIS) and IDENT.

Biometrics in the Department of Homeland Security

The use of biometrics within DHS plays a pivotal role in ensuring identity assurance and overall security. By collecting biometric data and linking it with specific biographic information, DHS can establish and verify an individual's identity during various encounters, such as visa applications, immigration benefits, or entry into the United States. Key aspects of DHS's biometric initiatives include:

Identity Assurance

  • Screening individuals against a watchlist of known or suspected terrorists, criminals, and immigration violators.
  • Conducting comprehensive fingerprint checks against the entire DHS database to detect aliases and fraudulent identification attempts.
  • Verifying that the biometrics of an individual match the ones associated with the presented identification document, preventing identity theft or misuse.
  • Delivering the results of these checks to decision-makers promptly and efficiently.

These services significantly reduce identity fraud, thwart criminals and immigration violators from crossing borders, and enhance the efficiency of travel requirements. Through Biometric Facial Comparison at U.S. Customs and Border Protection, powered by OBIM systems, thousands of ineligible individuals have been prevented from entering the United States based solely on biometric data.

Quality of Life and Security In addition to identity assurance, biometrics also play a vital role in confirming the claimed identity of travelers, workers, benefit applicants, and detainees. By cross-referencing biometric information, potential derogatory associations can be flagged, and any discrepancies in previous identities can be identified.

Biometrics in the Department of Defense

Within the DoD, the Defense Forensics and Biometrics Agency (DFBA) handles the collection and coordination of biometric data. The deployment of biometric technologies and forensic exploitation enhances multiple mission areas, allowing the DoD to:

Identity Assurance

  • Provide material evidence to support criminal prosecutions, linking individuals to hostile acts or crimes.
  • Screen for terrorists, foreign fighters, and insurgents attempting to hide their identities from U.S. Forces.
  • Safeguard U.S. borders by using biometrics to identify groups and individuals seeking entry with malicious intent.
  • Enhance physical and logical access control, allowing authorized individuals to gain access without traditional cards or badges while promptly flagging unauthorized individuals based on their biometric data.

Biometrics in the Department of Justice

The Department of Justice (DOJ) plays a significant role in leveraging biometrics to support the criminal justice community. With the world's largest and most efficient electronic repository of biometric and criminal history information, DOJ empowers law enforcement efforts by:

Identity Assurance

  • Managing the national fingerprint collection since 1924, ensuring accurate and extensive biometric identification capabilities.
  • Collecting high-value biometrics from foreign law enforcement partners to identify individuals associated with terrorism, serious crimes, or transnational criminal activity.
  • Mobilizing a rapid deployment team through the Quick Capture Platform, capable of swiftly providing identification services during special security events, critical incidents, or emergency operations.
  • Equipping FBI agents and task force officers with the Mobile Biometric Application (MBA), enabling them to quickly scan fingerprints and positively identify suspects domestically and internationally, streamlining field operations.
  • Sharing criminal and terrorist biometrics with the FBI's Criminal Justice Information Services Division as part of the Visa Waiver Program.

Biometrics in the Department of Commerce / National Institute of Standards and Technology

The National Institute of Standards and Technology (NIST) has been actively involved in biometric research for over six decades. Their work on fingerprint technologies for the FBI, starting in the 1960s, has contributed significantly to law enforcement and forensics. NIST supports government-wide efforts to improve biometric data collection, sharing, accuracy, and interoperability, working towards enhanced homeland security. Their focus includes:

  • Collection of high-quality biometrics.
  • Facilitating appropriate data sharing between agencies.
  • Ensuring accuracy and interoperability of biometric systems.

In conclusion, biometrics have revolutionized security practices across various domains, empowering agencies like the Department of Homeland Security, the Department of Defense, the Department of Justice, and the Department of Commerce/National Institute of Standards and Technology. By leveraging unique physical characteristics, biometrics strengthen identity assurance, improve security, and streamline processes, ultimately making the world a safer place.
