Biometric Authentication and Security in Government IT – FedTech Magazine


Biometrics technology first gained a fingerhold in government in the late 1800s, when police officers began to use fingerprints as a way to identify suspects. Since then, government use has expanded to include ID verification of federal employees, travelers and in some cases, the average citizen.

The technology has grown more sophisticated, recognizing unique features in the eyes, the face and even the way a person behaves, and the government is looking for ways to incorporate those new capabilities and biometric data into identification practices.

But there are also questions about the accuracy of the technology, and about the protection of privacy and civil liberties when facial recognition technologies are used to identify people for investigations. Nevertheless, biometrics remains the wave of the future.

“The era of the password is drawing to an end,” writes Walker Van Arsdale on CDW’s Solutions Blog. “While we’ve relied on secret pieces of information to safeguard our access to information and systems for decades, it’s clear that password security is no longer adequate.”

What Is Biometrics Technology?

Biometrics technology uses a person’s unique, relatively unchanging physical characteristics as a form of ID, rather than having the person rely on a forgettable and hackable password. It’s often used as the second factor in multifactor authentication.

Sensors detect the characteristic — for instance, a person may have to look into a scanner to have his or her iris scanned — then the computer runs that image against a pattern-recognition database. The system taps into that database, and if the person’s biometric data matches what’s on record, he gains admittance to the building or the network.

While most biometric data is used for employee identification, it’s also rolling out in areas besides the workplace. Most smartphones can be unlocked with a glance by the verified owner; laptops by companies including Acer and Dell include a fingerprint reader for security. Guests to Disney parks use their fingerprints to gain entry in addition to a ticket.

However, while the iris and the fingerprint are unchanging physical characteristics that can be easily matched, faces are less simple to identify using biometrics technology.

Facial recognition algorithms can have trouble identifying women and people of color; grow a beard or put on a pair of glasses, and that can confuse the algorithm as well. (There are, however, glasses under development that contain facial recognition software.)

In the government arena, a June 2019 Government Accountability Office report determined that the FBI needed to do more robust testing of its facial recognition technology to make sure it was as accurate as the FBI claimed.

As the size of a photo database increases, the accuracy of face recognition searches performed on that database can decrease due to lookalike faces,” the report states. “At the time of our review, FBI’s test database contained 926,000 photos while [its operational database] contained about 30 million photos.”

How Is the Federal Government Using Biometrics?

The Department of Homeland Security is one of the best-known federal users of biometric data, largely for screening travelers. The agency uses biometric technology to detect and prevent illegal entry, to verify information on visa applications and to keep legal travel and trade moving smoothly.

Since 2016, U.S. Customs and Border Protection has been working with airlines to use facial recognition technology as part of the preboarding screening process; at least five airlines now use it, largely for international flights (it’s voluntary for American citizens).

In 2017, President Donald Trump signed an executive order requiring that the top 20 U.S. airports use biometric technology and facial recognition by 2021 for all international passengers. Earlier this year, he signed the National Strategy to Combat Terrorism Travel, which calls for the increased use of biometric technology and data to stop terrorists from entering the U.S.

Recently, the Transportation Security Administration has tested automated biometric screening at Los Angeles International Airport and McCarren International Airport in Las Vegas. The LAX test involved cameras and scanners placed at special automated security gates; the Las Vegas test captures images at the regular checkpoint with the passenger’s permission.

CBP has processed more than 19 million travelers using facial recognition technology at airports and also at land crossings in the past three years, and has found a little more than 100 people who were trying to enter the U.S. by using others’ identities, reported The Hill.

“With facial comparison biometrics, CBP is … solving a security challenge while adding a convenience for travelers,” a CBP spokesperson told the newspaper.

DHS also shares its biometric information with the Justice and Defense departments to aid those agencies in their missions. Its Office of Biometric Identity Management has “the largest biometric repository in U.S. government,” according to its website.

That repository — the Automated Biometric Identification System, processes more than 300,000 biometric transactions per day and holds biometric data on more than 250 million people. DHS plans to upgrade the system and move it to the cloud so that it can potentially identify people through scars, tattoos and other physical markings as well.

While DHS and its component agencies are perhaps the most high-profile users of biometric data, other agencies are taking that road as well:

• The FBI calls its Next Generation Identification system “the world’s largest and most efficient electronic repository of biometric and criminal history information,” with biometric data including fingerprint and palm prints, iris identification, facial recognition data and photographs of tattoos and scars.

• The Defense Department is testing the use of biometric data to help verify employee ID. The Air Force, for example, is considering using artificial intelligence–powered facial recognition to clear legitimate visitors and workers through the gates at its bases; and the DOD in general is interested in using biometric data as the second factor in MFA. 

“I assume the technology is going to continue to get better and better, and will come to a point where it really is able to fully automate a lot more identification and decision making,” said Jeremy Grant, founder of the National Program Office for the National Strategy for Trusted Identities in Cyberspace at the National Institute of Standards and Technology, in an interview with Federal News Network.

Is Biometric Data Safe?

Biometrics security is critical; this data is among the most personal personally identifiable information that exists. Strong endpoint security and encryption are among the most reliable tools.

But at present, biometric data itself poses an unsolvable security problem: “In the event of a breach, it creates a Herculean challenge because physical attributions such as fingerprints cannot be replaced,” data security expert Kon Leong, CEO and co-founder at ZL Technologies, told CSO Online.

The number of hacks involving biometric data — and the number of organizations compiling biometric data without the owners of that data knowing about it — is on the rise.

Most recently, a biometrics company used to provide physical security for defense contractors, banks and Scotland Yard found that its worldwide database was improperly protected. More than 1 million fingerprints, facial recognition information and other personal data from companies around the world had been leaked to a public website.

In the noncriminal sector, agents with the FBI and Immigration and Customs Enforcement have turned state driver’s license databases into a facial-recognition gold mine, scanning through millions of Americans’ photos without their knowledge or consent, newly released documents show. That has raised civil liberties concerns

“We need strong legal safeguards that guarantee civil rights, fairness and accountability,” Kate Crawford, co-director of the AI Now Institute at New York University, wrote in the science journal Nature.

Ironically, one way to make biometric data more secure is to use passwords, reports GCN — strongly encrypted so that if the data is stolen, the passwords that release it are unreadable. Blockchain technology that allows only authorized parties to access the data may also be a solution, GCN reports.
