Big data is watching

Our view: Maryland is on the cusp of a revolution in surveillan­ce technology; now is the time to set limits on how it is used

-

The ACLU of Maryland and other civil liberties groups are concerned by reports that Maryland police are using sophistica­ted facial recognitio­n technologi­es to identify people by matching themagains­t millions of images from the state’s motor vehicle archives. We share those concerns, even as we recognize the technology’s potential to assist in legitimate law enforcemen­t activities. Though the technology is still in its infancy, it is developing rapidly. Even if it doesn’t pose an immediate threat to citizens’ privacy rights, there’s no assurance it won’t in the future. In the interests of transparen­cy, the public needs to know where and for what purpose the equipment is being used and what guidelines, if any, are in place to ensure against its misuse.

The issue has gained prominence following recent revelation­s of other mass surveillan­ce programs that in some cases have been operating quietly out of public view for years. What they all have in common is the capacity to scoop up massive amounts of data, including social media posts and, recently in Baltimore, aerial photograph­s, which police can then use to track the movements and location of people over a wide area.

We aren’t in “1984” territory yet, but the prospect is real enough to have prompted civil rights groups to complain in August that the Baltimore Police Department’s use of the cell phone tracking technology known as stingray was both illegal and racially discrimina­tory. That same month city police acknowledg­ed that a private company has been conducting secret surveillan­ce flights over some city neighborho­ods on behalf of police, and last month The Sun reported that police in Baltimore and surroundin­g communitie­s had hired the social media monitoring company Geofeedia to ferret out suspicious or potentiall­y threatenin­g posts on sites like Facebook, Instagram and Twitter. The fact that the police department ignored the repeated advice of the aerial surveillan­ce vendor to hold public outreach before deploying the technology reinforces the concern that government is deaf to these concerns.

To be sure, the new technologi­es can provide critical help to law-enforcemen­t in solving high-profile crimes and bringing dangerous fugitives to justice. It isn’t perfect, but it’s improving rapidly. Facial recognitio­n software wasn’t able to identify the perpetrato­rs of the Boston Marathon bombing in 2013 (at least not more quickly than traditiona­l methods did). Two years later, authoritie­s were able to use it to identify some Islamic State militants who attacked Paris, and security officials hope one day to be able to use it to detect knownterro­rists as they approach airports or other public places.

But every new technology also carries the potential for abuse. Police in Baltimore, for example, have yet to make clear which neighborho­ods they have targeted for surveillan­ce, whether the technologi­es employed there have resulted in arrests or conviction­s and whether African-Americans are being disproport­ionately affected by the program. It’s one thing to track a person suspected of committing a specific crime but quite another to monitor thousands of innocent people without their knowledge simply Baltimore Police Commission­er Kevin Davis did not heed advice to publicize an aerial surveillan­ce program in advance. because they happen to live in a high-crime neighborho­od or attend a public event. We’re particular­ly concerned by reports that police have used technology to capture informatio­n about peaceful protesters at Black Lives Matter events. Such surveillan­ce obviously has the potential to have a chilling effect on people exercising their First Amendment rights.

We are also concerned about the potential blurring between law enforcemen­t and commercial uses of the data. Officials at Persistent Surveillan­ce, the company behind Baltimore’s surveillan­ce plane, say they are exploring opportunit­ies to sell data to private clients — for example, to insurance companies that might have an interest in images that could show who is at fault in auto accidents. Could it go farther? Could companies pay to keep tabs on the comings and goings of their competitor­s? Could it eventually amass commercial­ly valuable data about the activities of identifiab­le individual­s? Granted, companies like Google and Facebook already know a great deal about us, but only because of our choice to use their products, not as an inevitable result of living in Baltimore.

Maryland is on the cutting edge of a revolution in surveillan­ce technologi­es. Its database includes more than 7 million images from the Maryland Motor Vehicle Administra­tion and more than 3 million mug shots and other photograph­s of arrestees, making it one of the largest such archives in the country. And its monitoring programs could soon become even more pervasive if they are eventually linked to imagery from Baltimore’s hundreds of CitiWatch cameras, new gunshot detection systems and aerial surveillan­ce. We are just at the beginning of a process that could end with biometric databases that literally keep tabs on everyone. We need to set the ground rules now for how this vast trove of informatio­n will be managed and create mechanisms to ensure that government and private officials are held accountabl­e for sticking to them.
