1 nation, tracked An investigation into the smartphone tracking industry from Times Stance

Every minute of every day, everywhere on the planet, dozens of companies — largely unregulated, little scrutinized — are logging the movements of tens of millions of people with mobile phones and storing the data in gigantic information files. The Times Privacy Projection obtained ane such file, past far the largest and almost sensitive e'er to be reviewed by journalists. It holds more than 50 billion location pings from the phones of more than than 12 million Americans as they moved through several major cities, including Washington, New York, San Francisco and Los Angeles.

Each piece of information in this file represents the precise location of a single smartphone over a menses of several months in 2016 and 2017. The information was provided to Times Opinion by sources who asked to remain anonymous because they were not authorized to share it and could face astringent penalties for doing and so. The sources of the data said they had grown alarmed almost how it might be driveling and urgently wanted to inform the public and lawmakers.

Afterward spending months sifting through the information, tracking the movements of people beyond the country and speaking with dozens of information companies, technologists, lawyers and academics who study this field, nosotros feel the aforementioned sense of alarm. In the cities that the data file covers, it tracks people from virtually every neighborhood and cake, whether they live in mobile homes in Alexandria, Va., or luxury towers in Manhattan.

One search turned upward more than than a dozen people visiting the Playboy Mansion, some overnight. Without much effort nosotros spotted visitors to the estates of Johnny Depp, Tiger Woods and Arnold Schwarzenegger, connecting the devices' owners to the residences indefinitely.

If you lived in i of the cities the dataset covers and use apps that share your location — anything from weather apps to local news apps to coupon savers — you could be in there, likewise.

If you could see the full trove, you might never employ your telephone the same way again.

The data reviewed by Times Opinion didn't come from a telecom or giant tech company, nor did information technology come up from a governmental surveillance performance. It originated from a location data company, one of dozens quietly collecting precise movements using software slipped onto mobile phone apps. You've probably never heard of most of the companies — and however to anyone who has admission to this data, your life is an open book. They tin see the places you go every moment of the day, whom you meet with or spend the night with, where you lot pray, whether you visit a methadone clinic, a psychiatrist's office or a massage parlor.

The Times and other news organizations have reported on smartphone tracking in the past. Merely never with a data gear up so large. Even still, this file represents just a small piece of what'due south collected and sold every twenty-four hours by the location tracking industry — surveillance and so omnipresent in our digital lives that information technology at present seems impossible for anyone to avoid.

It doesn't have much imagination to conjure the powers such always-on surveillance can provide an authoritarian regime like China's. Within America's own representative democracy, citizens would surely rise upwardly in outrage if the government attempted to mandate that every person above the historic period of 12 carry a tracking device that revealed their location 24 hours a day. Yet, in the decade since Apple tree's App Store was created, Americans have, app past app, consented to just such a system run by private companies. Now, equally the decade ends, tens of millions of Americans, including many children, find themselves carrying spies in their pockets during the day and leaving them beside their beds at nighttime — even though the corporations that control their data are far less accountable than the government would be.

[Related: Where Even the Children Are Being Tracked — We followed every move of people in one city. Then we went to tell them.]

"The seduction of these consumer products is so powerful that it blinds us to the possibility that there is some other fashion to go the benefits of the engineering without the invasion of privacy. But there is," said William Staples, founding manager of the Surveillance Studies Inquiry Center at the University of Kansas. "All the companies collecting this location data act as what I have called Tiny Brothers, using a multifariousness of data sponges to engage in everyday surveillance."

In this and subsequent articles we'll reveal what we've establish and why it has and then shaken us. We'll ask you lot to consider the national security risks the existence of this kind of data creates and the specter of what such precise, always-on human tracking might hateful in the hands of corporations and the government. We'll also look at legal and upstanding justifications that companies rely on to collect our precise locations and the deceptive techniques they use to lull us into sharing it.

Today, it's perfectly legal to collect and sell all this information. In the The states, as in about of the globe, no federal law limits what has get a vast and lucrative trade in human tracking. Only internal company policies and the decency of individual employees prevent those with access to the information from, say, stalking an estranged spouse or selling the evening commute of an intelligence officer to a hostile foreign ability.

Companies say the data is shared only with vetted partners. As a society, we're choosing simply to take their word for that, displaying a blithe faith in corporate beneficence that nosotros don't extend to far less intrusive yet more heavily regulated industries. Even if these companies are acting with the soundest moral code imaginable, in that location'southward ultimately no foolproof way they can secure the data from falling into the easily of a strange security service. Closer to home, on a smaller yet no less troubling scale, there are often few protections to stop an individual analyst with access to such information from tracking an ex-lover or a victim of abuse.

A DIARY OF YOUR EVERY MOVEMENT

The companies that collect all this data on your movements justify their business on the ground of three claims: People consent to be tracked, the data is bearding and the data is secure.

None of those claims concord upwardly, based on the file nosotros've obtained and our review of company practices.

Yes, the location data contains billions of data points with no identifiable information like names or email addresses. But it'southward child's play to connect real names to the dots that appear on the maps.

Here'south what that looks like.

The information included more than
than 10,000 smartphones tracked
in Fundamental Park.

Hither is one smartphone, isolated
from the crowd.

Here are all pings from
that smartphone over the period covered by the data.

Connecting those pings reveals a diary of the person'due south life.

In most cases, ascertaining a home location and an office location was enough to identify a person. Consider your daily commute: Would any other smartphone travel directly betwixt your house and your office every solar day?

Describing location information as bearding is "a completely imitation merits" that has been debunked in multiple studies, Paul Ohm, a law professor and privacy researcher at the Georgetown University Police Center, told us. "Actually precise, longitudinal geolocation information is absolutely impossible to anonymize."

"D.Northward.A.," he added, "is probably the only matter that's harder to anonymize than precise geolocation data."

Notwithstanding companies continue to claim that the data are anonymous. In marketing materials and at trade conferences, anonymity is a major selling point — key to allaying concerns over such invasive monitoring.

To evaluate the companies' claims, we turned most of our attention to identifying people in positions of power. With the help of publicly available information, like home addresses, nosotros easily identified and then tracked scores of notables. Nosotros followed military machine officials with security clearances equally they drove domicile at dark. Nosotros tracked law enforcement officers as they took their kids to school. We watched high-powered lawyers (and their guests) every bit they traveled from individual jets to vacation backdrop. Nosotros did not name whatever of the people we identified without their permission.

The data set is large plenty that information technology surely points to scandal and crime but our purpose wasn't to dig upwardly dirt. We wanted to document the take chances of underregulated surveillance.

Watching dots move beyond a map sometimes revealed hints of faltering marriages, evidence of drug habit, records of visits to psychological facilities.

Connecting a sanitized ping to an actual man in fourth dimension and place could feel like reading someone else's diary.

In one case, we identified Mary Millben, a singer based in Virginia who has performed for 3 presidents, including President Trump. She was invited to the service at the Washington National Cathedral the morning after the president's inauguration. That's where we first establish her.

She remembers how, surrounded by dignitaries and the first family unit, she was moved by the music echoing through the recesses of the cathedral while members of both parties joined together in prayer. All the while, the apps on her phone were as well monitoring the moment, recording her position and the length of her stay in meticulous detail. For the advertisers who might buy access to the information, the intimate prayer service could well supply some profitable marketing insights.

"To know that you have a list of places I have been, and my phone is connected to that, that'southward scary," Ms. Millben told united states of america. "What'southward the business of a company benefiting off of knowing where I am? That seems a little dangerous to me."

Similar many people we identified in the data, Ms. Millben said she was careful about limiting how she shared her location. Nevertheless like many of them, she also couldn't proper noun the app that might take nerveless it. Our privacy is only as secure equally the least secure app on our device.

"That makes me uncomfortable," she said. "I'm sure that makes every other person uncomfortable, to know that companies can have free rein to take your data, locations, whatsoever else they're using. It is disturbing."

The inauguration weekend yielded a trove of personal stories and experiences: elite attendees at presidential ceremonies, religious observers at church building services, supporters assembling beyond the National Mall — all surveilled and recorded permanently in rigorous particular.

Protesters were tracked just as rigorously. Later on the pings of Trump supporters, basking in victory, vanished from the National Mall on Friday evening, they were replaced hours afterwards by those of participants in the Women's March, as a crowd of nearly half a million descended on the capital. Examining just a photo from the result, you lot might be hard-pressed to tie a confront to a name. Simply in our data, pings at the protest continued to articulate trails through the data, documenting the lives of protesters in the months earlier and later the protest, including where they lived and worked.

We spotted a senior official at the Section of Defence walking through the Women'due south March, beginning on the National Mall and moving past the Smithsonian National Museum of American History that afternoon. His married woman was also on the mall that day, something we discovered later tracking him to his home in Virginia. Her phone was also effulgent out location information, forth with the phones of several neighbors.

The official's data trail also led to a high schoolhouse, homes of friends, a visit to Joint Base Andrews, workdays spent in the Pentagon and a ceremony at Joint Base Myer-Henderson Hall with President Barack Obama in 2017 (nearly a dozen more phones were tracked there, too).

Inauguration Day weekend was marked past other protests — and riots. Hundreds of protesters, some in black hoods and masks, gathered north of the National Mall that Fri, somewhen setting burn down to a limousine near Franklin Foursquare. The data documented those rioters, too. Filtering the information to that precise time and location led usa to the doorsteps of some who were there. Police were present besides, many with faces obscured past riot gear. The data led us to the homes of at least two constabulary officers who had been at the scene.

As revealing as our searches of Washington were, nosotros were relying on just i slice of data, sourced from one visitor, focused on one city, covering less than one year. Location data companies collect orders of magnitude more than information every day than the totality of what Times Opinion received.

Data firms also typically depict on other sources of information that we didn't use. Nosotros lacked the mobile advertising IDs or other identifiers that advertisers oftentimes combine with demographic information similar habitation ZIP codes, age, gender, fifty-fifty phone numbers and emails to create detailed audience profiles used in targeted advert. When datasets are combined, privacy risks can be amplified. Any protections existed in the location dataset can crumble with the improver of but one or 2 other sources.

There are dozens of companies profiting off such information daily across the world — by collecting information technology directly from smartphones, creating new technology to meliorate capture the data or creating audience profiles for targeted advertising.

The full collection of companies can feel dizzying, equally it's constantly changing and seems impossible to pin downwards. Many apply technical and nuanced language that may be confusing to boilerplate smartphone users.

While many of them have been involved in the business organisation of tracking the states for years, the companies themselves are unfamiliar to most Americans. (Companies tin piece of work with data derived from GPS sensors, Bluetooth beacons and other sources. Non all companies in the location information business collect, buy, sell or work with granular location data.)

Location data companies generally downplay the risks of collecting such revealing information at scale. Many as well say they're non very concerned near potential regulation or software updates that could make it more difficult to collect location information.

"No, it doesn't really keep u.s.a. up at nighttime," Brian Czarny, chief marketing officer at Factual, one such company, said. He added that Factual does non resell detailed data like the information we reviewed. "We don't experience similar anybody should be doing that because it's a risk to the whole business organization," he said.

In absence of a federal privacy law, the industry has largely relied on self-regulation. Several industry groups offering ethical guidelines meant to govern it. Factual joined the Mobile Marketing Association, along with many other data location and marketing companies, in drafting a pledge intended to improve its self-regulation. The pledge is slated to be released next twelvemonth.

States are starting to respond with their own laws. The California Consumer Protection Human activity goes into upshot side by side twelvemonth and adds new protections for residents in that location, like allowing them to inquire companies to delete their data or preclude its sale. But aside from a few new requirements, the law could leave the industry largely unencumbered.

"If a private company is legally collecting location data, they're free to spread it or share it still they want," said Calli Schroeder, a lawyer for the privacy and data protection company VeraSafe.

The companies are required to disclose very niggling about their data collection. By law, companies need only describe their practices in their privacy policies, which tend to be dumbo legal documents that few people read and fifty-fifty fewer tin truly understand.

EVERYTHING Tin can BE HACKED

Does it really matter that your data isn't actually bearding? Location data companies argue that your data is safe — that information technology poses no real risk because it's stored on guarded servers. This assurance has been undermined by the parade of publicly reported information breaches — to say nothing of breaches that don't make headlines. In truth, sensitive information tin can be hands transferred or leaked, equally evidenced by this very story.

We're constantly shedding data, for instance, past surfing the cyberspace or making credit card purchases. But location information is dissimilar. Our precise locations are used fleetingly in the moment for a targeted ad or notification, but so repurposed indefinitely for much more than profitable ends, like tying your purchases to billboard ads you drove by on the expressway. Many apps that use your location, similar weather services, work perfectly well without your precise location — merely collecting your location feeds a lucrative secondary business organisation of analyzing, licensing and transferring that information to 3rd parties.

The data contains elementary information like date, latitude and longitude, making information technology easy to inspect, download and transfer. Note: Values are randomized to protect sources and device owners.

For many Americans, the only real run a risk they face from having their information exposed would be embarrassment or inconvenience. Simply for others, like survivors of abuse, the risks could exist substantial. And who can say what practices or relationships any given individual might want to go on private, to withhold from friends, family, employers or the government? We plant hundreds of pings in mosques and churches, abortion clinics, queer spaces and other sensitive areas.

One time, nosotros observed a change in the regular movements of a Microsoft engineer. He made a visit one Tuesday afternoon to the main Seattle campus of a Microsoft competitor, Amazon. The post-obit month, he started a new job at Amazon. It took minutes to place him equally Ben Broili, a manager at present for Amazon Prime number Air, a drone delivery service.

"I can't say I'm surprised," Mr. Broili told united states in early December. "But knowing that yous all can get ahold of it and comb through and place me to come across where I work and live — that's weird." That we could so easily discern that Mr. Broili was out on a chore interview raises some obvious questions, like: Could the internal location surveillance of executives and employees get standard corporate practice?

Ben Broili's interview at Amazon was captured in the information. Grant Hindsley for The New York Times

Mr. Broili wasn't worried about apps cataloguing his every move, simply he said he felt unsure virtually whether the tradeoff betwixt the services offered by the apps and the sacrifice of privacy was worth it. "It's an awful lot of data," he said. "And I really still don't sympathise how it'southward being used. I'd have to run into how the other companies were weaponizing or monetizing it to make that call."

If this kind of location data makes it easy to go on tabs on employees, it makes it just as simple to stalk celebrities. Their private carry — fifty-fifty in the dead of night, in residences and far from paparazzi — could come under fifty-fifty closer scrutiny.

Reporters hoping to evade other forms of surveillance by coming together in person with a source might want to rethink that practice. Every major newsroom covered by the data contained dozens of pings; we easily traced one Washington Postal service journalist through Arlington, Va.

In other cases, there were detours to hotels and belatedly-dark visits to the homes of prominent people. Ane person, plucked from the data in Los Angeles nigh at random, was found traveling to and from roadside motels multiple times, for visits of only a few hours each time.

While these pointillist pings don't in themselves reveal a complete movie, a lot can be gleaned by examining the appointment, time and length of time at each signal.

Large data companies like Foursquare — maybe the most familiar proper noun in the location data business — say they don't sell detailed location information like the kind reviewed for this story only rather utilise it to inform analysis, such every bit measuring whether yous entered a store after seeing an advert on your mobile phone.

But a number of companies exercise sell the detailed data. Buyers are typically data brokers and advert companies. But some of them have little to do with consumer advertizement, including financial institutions, geospatial analysis companies and real manor investment firms that can process and analyze such large quantities of information. They might pay more than than $ane million for a tranche of information, according to a former location information company employee who agreed to speak anonymously.

Location data is also collected and shared alongside a mobile ad ID, a supposedly anonymous identifier about 30 digits long that allows advertisers and other businesses to tie activity together across apps. The ID is also used to combine location trails with other information like your name, dwelling address, email, phone number or fifty-fifty an identifier tied to your Wi-Fi network.

The information tin change hands in almost existent time, then fast that your location could be transferred from your smartphone to the app's servers and exported to third parties in milliseconds. This is how, for case, you might see an advertisement for a new motorcar some time after walking through a dealership.

That data tin can then be resold, copied, pirated and driveling. In that location's no fashion you lot can ever recollect information technology.

Location information is about far more than consumers seeing a few more relevant ads. This information provides disquisitional intelligence for big businesses. The Atmospheric condition Channel app'southward parent company, for instance, analyzed users' location data for hedge funds, co-ordinate to a lawsuit filed in Los Angeles this year that was triggered by Times reporting. And Foursquare received much attention in 2016 after using its data trove to predict that after an E. coli crisis, Chipotle'due south sales would drop by 30 pct in the coming months. Its aforementioned-shop sales ultimately fell 29.7 percentage.

Much of the business organisation over location data has focused on telecom giants like Verizon and AT&T, which accept been selling location information to third parties for years. Last year, Motherboard, Vice's technology website, found that in one case the data was sold, it was being shared to aid bounty hunters find specific cellphones in real fourth dimension. The resulting scandal forced the telecom giants to pledge they would stop selling location movements to data brokers.

However no police prohibits them from doing so.

Location data is transmitted from your telephone via software evolution kits, or South.D.Ks. every bit they're known in the trade. The kits are small programs that can exist used to build features within an app. They make it easy for app developers to simply include location-tracking features, a useful component of services like atmospheric condition apps. Because they're so useful and easy to use, Southward.D.K.s are embedded in thousands of apps. Facebook, Google and Amazon, for instance, accept extremely popular South.D.1000.s that allow smaller apps to connect to bigger companies' advertising platforms or help provide spider web traffic analytics or payment infrastructure.

But they could also sit on an app and collect location data while providing no real service back to the app. Location companies may pay the apps to be included — collecting valuable data that can be monetized.

"If you have an Southward.D.K. that's oft collecting location data, it is more than likely being resold beyond the industry," said Nick Hall, chief executive of the data market company VenPath.

THE 'HOLY GRAIL' FOR MARKETERS

If this information is so sensitive, why is it collected in the starting time place?

For brands, following someone's precise movements is key to understanding the "customer journey" — every step of the procedure from seeing an advertizing to buying a product. Information technology's the Holy Grail of advertising, one marketer said, the complete picture show that connects all of our interests and online action with our real-world deportment.

One time they accept the consummate client journey, companies know a lot about what we want, what we buy and what made us buy it. Other groups take begun to find ways to use information technology too. Political campaigns could analyze the interests and demographics of rally attendees and use that information to shape their messages to try to manipulate particular groups. Governments around the world could take a new tool to identify protestors.

Pointillist location data also has some clear benefits to society. Researchers tin use the raw data to provide primal insights for transportation studies and government planners. The City Council of Portland, Ore., unanimously approved a deal to study traffic and transit past monitoring millions of cellphones. Unicef announced a plan to use aggregated mobile location data to study epidemics, natural disasters and demographics.

For individual consumers, the value of abiding tracking is less tangible. And the lack of transparency from the advertizing and tech industries raises however more than concerns.

Does a coupon app need to sell second-by-2d location data to other companies to be profitable? Does that really justify assuasive companies to rail millions and potentially betrayal our private lives?

Data companies say users consent to tracking when they concur to share their location. But those consent screens rarely make articulate how the information is being packaged and sold. If companies were clearer about what they were doing with the data, would anyone concord to share information technology?

What about data collected years ago, before hacks and leaks made privacy a forefront issue? Should it still exist used, or should it be deleted for good?

If it's possible that information stored deeply today can easily be hacked, leaked or stolen, is this kind of data worth that hazard?

Is all of this surveillance and risk worth it just so that we tin can be served slightly more than relevant ads? Or and so that hedge fund managers can become richer?

The companies profiting from our every motion can't be expected to voluntarily limit their practices. Congress has to step in to protect Americans' needs equally consumers and rights every bit citizens.

Until then, one thing is certain: We are living in the world's most advanced surveillance organisation. This organization wasn't created deliberately. Information technology was built through the interplay of technological advance and the profit motive. It was built to make money. The greatest pull a fast one on applied science companies ever played was persuading society to surveil itself.
