License Plate Scanners

Automated License Plate Readers (ALPR)

Plenty to Hide

By Jay Stanley, Senior Policy Analyst, ACLU Speech, Privacy and Technology Project at 1:57pm

A commentator on my recent post about the DEA installing license plate scanners on the nation’s interstate highways asks, “If you aren't doing anything illegal why would you care if someone captures your license plate number?”

Another commentator countered: “If I'm not doing anything illegal, why do the police need to record my license plate number?”

What We Know About License Plate Tracking, What We Don't, And Our Plan to Find Out More

By Kade Crockford, Director, ACLU of Massachusetts Technology for Liberty Project at 12:31pm

Today the ACLU is launching a nationwide effort to find out more about automatic license plate readers (ALPR). By snapping photographs of each license plate they encounter—up to three thousand per minute—and retaining records of who was where when, license plate readers are fundamentally threatening our freedom on the open road.

Report: 85 Percent Of Law Enforcement Agencies Will Have License Plate Readers Within The Next Five Years

By Kade Crockford, Director, ACLU of Massachusetts Technology for Liberty Project at 12:58pm

Automatic license plate readers don’t pose much of a threat to our privacy if there aren’t very many of them. Like surveillance cameras, they really only become a problem when the data they collect are situated in a broader context of pervasive monitoring. One data point showing that your car drove past a stationary license plate reader on one highway doesn’t tell the government very much. But the data points begin to pile up when the surveillance cameras and license plate readers are on every street corner and police cruiser. And absent commonsense limits, that means police and prosecutors (and anyone else who gets at the database) can map your movements with the click of a button.

DEA Recording Americans’ Movements on Highways, Creating Central Repository of Plate Data

By Jay Stanley, Senior Policy Analyst, ACLU Speech, Privacy and Technology Project at 3:58pm

The DEA wants to capture the license plates of all vehicles traveling along Interstate 15 in Utah, and store that data for two years at their facility in Northern Virginia. And, as a DEA official told Utah legislators at a hearing this week (attended by ACLU of Utah staff and covered in local media), these scanners are already in place on “drug trafficking corridors” in California and Texas and are being considered for Arizona as well. The agency is also collecting plate data from unspecified other sources and sharing it with over ten thousand law enforcement agencies around the nation.

License Plate Scanners Logging Our Every Move

If we do not limit the use of automated license plate readers, it will represent a significant step toward the creation of a surveillance society in the United States.

Police “Google Searches” Through Our Location History? No Thanks

By Kade Crockford, Director, ACLU of Massachusetts Technology for Liberty Project at 3:24pm

Imagine a searchable database that would enable police or federal agents to instantly track everywhere you’ve ever driven in your car, like a “Google search” of your location over a period of months or even years. According to a law enforcement data manager speaking at a 2010 National Institute of Justice conference, that’s where the government is headed.

Boston Police Store License Plate Data For “Intelligence” Purposes

By Kade Crockford, Director, ACLU of Massachusetts Technology for Liberty Project at 2:29pm

This summer ACLU affiliates all around the country filed open-records requests seeking information about how government agencies are using automated license plate readers. One set of records, released this week to the ACLU of Massachusetts by the police department here in Boston, provides a snapshot of the data-collection practices that are taking place around the nation.

Uncovering License Plate Scanners: The Next Big Thing in Government Tracking

By Kathryn Bendoraitis , ACLU of Maryland & David Rocah, Staff Attorney, ACLU of Maryland at 12:40pm

Maryland may be positioned to lead the nation in tracking the location and movements of innocent people through Automatic License Plate Readers (ALPRs). That is why the ACLU of Maryland joined with ACLU affiliates in 38 other states to file public records requests seeking information about the law enforcement collection and retention of ALPR data. Maryland seems to be (or claims to be) one of the national leaders in the troubling centralized aggregation and storage of ALPR data, which raises significant privacy concerns. 

ACLU Sues Federal Agencies for Records on License Plate Tracking

By Kade Crockford, Director, ACLU of Massachusetts Technology for Liberty Project at 12:58pm

Today we sued the federal government to enforce Freedom of Information Act requests we filed over the summer to learn about how it is using a technology that can track Americans’ location with increasing efficacy: automated license plate readers. (See today’s legal complaint, our original FOIA requests, and a blog we posted when we made those requests.)

Extreme Traffic Enforcement

By Jay Stanley, Senior Policy Analyst, ACLU Speech, Privacy and Technology Project at 2:05pm

In a recent post I pointed out various ways that license plate recognition devices could be combined with other databases to invade privacy.

One obvious use for ALPR that I did not mention is speeding tickets. If you’ve gotten from point A to point B in less time than would be possible at the speed limit, it would be simple to have the system automatically spit you out a citation. Surveillance drones could also be used for traffic enforcement.
