What is privacy? Why should we want to hold onto it? Why is it important, necessary, precious?  Is it just some prissy relic of the pretechnological past?

We talk about this now because of Edward Snowden, the National Security Agency revelations, and new fears that we are operating, all of us, within what has become or is becoming a massive surveillance state. They log your calls here, they can listen in, they can read your emails. They keep the data in mammoth machines that contain a huge collection of information about you and yours. This of course is in pursuit of a laudable goal, security in the age of terror.

Is it excessive? It certainly appears to be. Does that matter? Yes. Among other reasons: The end of the expectation that citizens’ communications are and will remain private will probably change us as a people, and a country.

Among the pertinent definitions of privacy from the Oxford English Dictionary: “freedom from disturbance or intrusion,” “intended only for the use of a particular person or persons,” belonging to “the property of a particular person.” Also: “confidential, not to be disclosed to others.” Among others, the OED quotes the playwright Arthur Miller, describing the McCarthy era: “Conscience was no longer a private matter but one of state administration.”

Privacy is connected to personhood. It has to do with intimate things—the innards of your head and heart, the workings of your mind—and the boundary between those things and the world outside.

A loss of the expectation of privacy in communications is a loss of something personal and intimate, and it will have broader implications. That is the view of Nat Hentoff, the great journalist and civil libertarian. He is 88 now and on fire on the issue of privacy. “The media has awakened,” he told me. “Congress has awakened, to some extent.” Both are beginning to realize “that there are particular constitutional liberty rights that [Americans] have that distinguish them from all other people, and one of them is privacy.”

Mr. Hentoff sees excessive government surveillance as violative of the Fourth Amendment, which protects “the right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures” and requires that warrants be issued only “upon probable cause . . . particularly describing the place to be searched, and the persons or things to be seized.”

But Mr. Hentoff sees the surveillance state as a threat to free speech, too. About a year ago he went up to Harvard to speak to a class. He asked, he recalled: “How many of you realize the connection between what’s happening with the Fourth Amendment with the First Amendment?” He told the students that if citizens don’t have basic privacies—firm protections against the search and seizure of your private communications, for instance—they will be left feeling “threatened.” This will make citizens increasingly concerned “about what they say, and they do, and they think.” It will have the effect of constricting freedom of expression. Americans will become careful about what they say that can be misunderstood or misinterpreted, and then too careful about what they say that can be understood. The inevitable end of surveillance is self-censorship.

All of a sudden, the room became quiet. “These were bright kids, interested, concerned, but they hadn’t made an obvious connection about who we are as a people.” We are “free citizens in a self-governing republic.”

Mr. Hentoff once asked Justice William Brennan “a schoolboy’s question”: What is the most important amendment to the Constitution? “Brennan said the First Amendment, because all the other ones come from that. If you don’t have free speech you have to be afraid, you lack a vital part of what it is to be a human being who is free to be who you want to be.” Your own growth as a person will in time be constricted, because we come to know ourselves by our thoughts.

He wonders if Americans know who they are compared to what the Constitution says they are.

Mr. Hentoff’s second point: An entrenched surveillance state will change and distort the balance that allows free government to function successfully. Broad and intrusive surveillance will, definitively, put government in charge. But a republic only works, Mr. Hentoff notes, if public officials know that they—and the government itself—answer to the citizens. It doesn’t work, and is distorted, if the citizens must answer to the government. And that will happen more and more if the government knows—and you know—that the government has something, or some things, on you. “The bad thing is you no longer have the one thing we’re supposed to have as Americans living in a self-governing republic,” Mr. Hentoff said. “The people we elect are not your bosses, they are responsible to us.” They must answer to us. But if they increasingly control our privacy, “suddenly they’re in charge if they know what you’re thinking.”

This is a shift in the democratic dynamic. “If we don’t have free speech then what can we do if the people who govern us have no respect for us, may indeed make life difficult for us, and in fact belittle us?”  If massive surveillance continues and grows, could it change the national character? “Yes, because it will change free speech.”

Smithsonian: What Phone Companies Are Doing With All That Data From Your Phone

Smithsonian: What Phone Companies Are Doing With All That Data From Your Phone

Cell phones are so many things now–computer, map, clock, calculator, camera, shopping device, concierge, and occasionally, a phone. But more than anything, that little device that never leaves your person is one amazingly prolific data engine.

Which is why last October, Verizon Wireless, the largest U.S, carrier with almost 100 million customers, launched a new division called Precision Market Insights. And why, at about the same time, Madrid-based Telefonica, one of the world’s largest mobile network providers, opened its own new business unit, Telefonica Dynamic Insights.

The point of these ventures is to mine, reconstitute and sell the enormous amount of data that phone companies gather about our behavior. Every time we make a mobile call or send a text message–which pings a cell tower–that info is recorded. So, with enough computer power, a company can draw pretty accurate conclusions about how and when people move through a city or a region. Or they can tell where people have come from to attend an event. As part of a recent case study, for example, Verizon was able to say that people with Baltimore area codes outnumbered those with San Francisco area codes by three to one inside the New Orleans Superdome for the Super Bowl in February.

In a world enamored of geolocation, this is digital gold. It’s one thing to know the demographic blend of a community, but to be able to find out how many people pass by a business and where they’re coming from, that adds a whole nother level of precision to target marketing.

Follow the crowd

But this data have value beyond companies zeroing in on potential customers. It’s being used for social science, even medical research. Recently IBM crunched numbers from 5 million phone users in the Ivory Coast in Africa and, by tracking movements of people through which cell towers they connected to, it was able to recommend 65 improvements to bus service in the city of Abidjan.

And computer scientists at the University of Birmingham in England have used cell phone data to fine tune analysis of how epidemics spread. Again, it’s about analyzing how people move around. Heretofore, much of what scientists knew about the spread of contagious diseases was based largely on guesswork. But now, thanks to so many pings from so many phones, there’s no need to guess.

It’s important to point out that no actual identities are connected to cell phone data. It all gets anonymized, meaning there shouldn’t be a way to track the data back to real people.

There shouldn’t be.

Leaving a trail

But a study published in Scientific Reports in March found that even anonymized data may not be so anonymous after all. A team of researchers from Louvain University in Belgium, Harvard and M.I.T. found that by using data from 15 months of phone use by 1.5 million people, together with a similar dataset from Foursquare, they could identify about 95 percent of the cell phones users with just four data points and 50 percent of them with just two data points. A data point is an individual’s approximate whereabouts at the approximate time they’re using their cell phone.

The reason that only four locations were necessary to identify most people is that we tend to move in consistent patterns. Just as everyone has unique fingerprints, everyone has unique daily travels. While someone wouldn’t necessarily be able to match the path of a mobile phone–known as a mobility trace–to a specific person, we make it much easier through geolocated tweets or location “check-ins,” such as when we use Foursquare.

“In the 1930s, it was shown that you need 12 points to uniquely identify and characterize a fingerprint,” the study’s lead author, Yves-Alexandre de Montijoye, told the BBC in a recent interview. “What we did here is the exact same thing, but with mobility traces. The way we move and the behavior is so unique that four points are enough to identify 95 percent of the people.”

“We think this data is more available than people think. When you share information, you look around and you feel like there are lots of people around–in a shopping center or a tourist place–so you feel this isn’t sensitive information.”

In other words, you feel anonymous. But are you really? De Montijoye said the point of his team’s research wasn’t to conjure up visions of Big Brother. He thinks there’s much good that can come from mining cell phone data, for businesses, for city planners, for scientists, for doctors. But he thinks it’s important to recognize that today’s technology makes true privacy very hard to keep.

The title of the study? “Unique in the Crowd.”

Private lives

Here are other recent developments related to mobile phones and their data:

  • Every picture tells your story: Scientists at Carnegie Mellon University’s Human Computer Interaction Center say their research of 100 smartphone apps found that about half of them raised privacy concerns. For instance, a photo-sharing app like Instagram provided information that allowed them to easily discover the location of the person who took the photo.
  • Cabbies with cameras: In the Mexican city of Tuxtla Gutiérrez, taxi drivers have been provided with GPS-enabled cell phones and encouraged to send messages and photographs about accidents or potholes or broken streetlights.
  • Follow that cell: Congress has started looking into the matter of how police use cell phone data to track down suspects. The key issue is whether they should be required to get a warrant first.
  • Follow that cell II: Police in Italy have started using a data analysis tool called LogAnalysis that makes it especially easy to visualize the relationships among conspiring suspects based on their phone calls. In one particular case involving a series of robberies, the tool showed a flurry of phone activity among the suspects before and after the heists, but dead silence when the crimes were being committed.

Video bonus: If you’re at all paranoid about how much data can be gleaned from how you use your mobile phone, you may not want to watch this TED talk by Malte Spitz.
