Biometric Policing: More Local Police Using Facial Recognition Software

A recent New York Times article details the frighteningly pervasive application of facial recognition softwares, originally developed for overseas military use, to local police departments across the country. Because the application of the technology to domestic police forces is rather recent, there are no clear guidelines or restrictions on its use. Timothy Williams reports:

“The software can identify 16,000 points on a person’s face – to determine the distance between the eyes or the shape of the lips, for instance – and compare them with thousands of similar points in police booking or other photos at a rate of more than one million faces a second.”

Despite public reservations about police misconduct, “the F.B.I. is pushing ahead with its $1 billion Next Generation Identification program, in which the agency will gather data like fingerprints, iris scans and photographs, as well as information collected through facial recognition software. That software is capable of analyzing driver’s license photos and images from the tens of thousands of surveillance cameras around the country. The F.B.I. system will eventually be made accessible to more than 18,000 local, state, federal and international law enforcement agencies,” the article reports.

“But people who are not criminal suspects are included in the database, and the error rate for the software is as high as 20  – meaning the authorities could misidentify millions of people.”

Such cutting edge technologies that merge biometric measurements with the power of big data draw on a long history. As early as 1879, French police officer and researcher Alphonse Bertillon devised a series of standardized measurements through which criminal suspects could be identified. Introduced in the US in 1887, Bertillon System would gain widespread acceptance until it was supplanted by fingerprinting as a primary means of law enforcement identification.

Bertillon’s reliance on facial measurements was contemporaneous with the popularization of phrenology and later eugenics, which used similar measurement techniques to attempt to distinguish superior and inferior biological “races”. How might the racial application of such measurements have distorted its use by law enforcement? How might contemporary issues of racism in policing be impacted by the use of new biometric technologies?

How Airport Biometrics Impact Transgender and Gender Non-Conforming People

This article is from 2012, but contains information that will be new to most. Alissa Bohling reports for on how the use of biometrics technology by airport security impacts transgender and gender non-conforming travelers, locating the nexus of race, religion, gender, and sexuality in the War on Terror:

“Since when did travelers’ gender become the Transportation Security Administration’s (TSA) business? Since at least September of 2003, when the Department of Homeland Security (DHS) issued an advisory warning against “Al-Qaeda’s continued efforts to plan multiple attacks against the US and US interests overseas.” The advisory included a list of potential terrorism targets, a mention of recent arrests of unnamed terror suspects and this warning: “Male bombers may dress as females in order to discourage scrutiny.”

Maybe there was verifiable intelligence about male terrorists who like to slip women’s wear over their explosive devices. Or maybe the wardens of the security state read one too many spy novels. But either way, bringing gender into the security arena has major consequences.



Since the DHS advisory, at least two other factors have brought gender further into the national security equation. One is Secure Flight, the program begun in 2009 requiring passengers to disclose their birth date and gender to airlines to be compared with their government-issued photo ID, purportedly in order to reduce the number of false matches to names on the federal watch list.

The other is the widespread use of body scanners.

Because gender has become one of the first markers in the technology-centric race for body-based data – known as “biometrics” in surveillance-speak – transgender and gender non-conforming people have been some of the first and most directly affected.

In an investigation begun during our “Surveillance in the Homeland” series on civil liberties in post-9/11 America, Truthout uncovered how their experiences illustrate what’s at stake when the human body becomes a data point in the war on terror.”
