Minimizing your digital trail

WASHINGTON — In popular culture, going “off the grid” is generally portrayed as either unsustainable or isolated: a protagonist angers some omniscient corporate or government agency and has to hole up in a remote cabin in the woods until he can clear his name or an anti-government extremist sets up camp, also in the middle of nowhere, living off the land, utterly cut off from society at large.

But is there a way to live normally while also living less visibly on the grid? What steps can you take to reduce your digital footprint that don’t overly restrict your movements?

What is a digital footprint?

Your digital footprint is the data you leave behind when you use a digital service—browse the web, swipe a rewards card, post on social media. Your digital footprint is usually one of two classifications: active or passive.

Your active digital footprint is any information you willingly give out about yourself, from the posts you put up on Facebook to the location information you give to your local mass transit system when you swipe your transit pass.

By contrast, your passive digital footprint is information that’s being collected about you without your express knowledge or authorization, for example, the “cookies” and “hits” saved when you visit a website. When you see personalized ads on Google, for example, those are tailored to you through collection of your personal preferences as inferred through collection of your passive digital footprint.

To assess my digital footprint, I looked through my wallet, my computer and my phone.

The footprint in your wallet

First, the wallet: I have several rewards cards, each representing a company that has a record of me in its database that shows how often I shop and what I buy, which is linked to my name, address, email and birthday—plus a security question in case I forget my password, usually my mother’s middle name.

While I would consider this information fairly benign—they don’t have my credit card information or my Social Security number—these companies can still make many inferences about me from my purchases. CVS, for example, could probably say fairly accurately if I’m sick based on my purchase of medications, whether I’m sexually active based on birth control purchases and any medical conditions I may have based on my prescription purchases.

If I wanted to minimize my digital footprint, I could terminate all my rewards accounts and refrain from opening any more. For me, though, it’s worth allowing these companies to collect my information in order to receive the deals, coupons and specials afforded me as a rewards member.

Next up is my transit pass, which is linked to my name, local address and debit card. The transit authority has a record of every time I swipe my way onto a city bus or train, a record of my movements linked to my name.

A minimal-footprint alternative to a transit pass is single-use fare cards. If purchased with cash, they would leave no record of my travels linked to my name. While this, like the rewards cards, is feasible, it’s far less convenient than the pass —so much less so that again I’m willing to compromise my privacy.

My debit card and insurance card are the two highest-value sources of personal information, but both are utterly necessary—living half a country away from my local credit union, I need my debit card to complete necessary transactions. My medical insurance card, relatively useless to identity thieves unless they have an ID with my name on it, does represent another large file in a database with my personal information—doctors’ visits, prescriptions and hospital stays for the past several years. People with just the physical card, not my license or information, can’t do much with that, but if a hacker gets to that information it could be very damaging.

No driver’s license? No credit card?

To minimize my digital footprint, then, I could pare down my wallet to just the absolute necessities—my insurance card, debit card and my license. You didn’t talk about your license

Computer footprint

If I’m guilty of leaving a large digital footprint, all my worst infractions probably happen across the Web.

Between Facebook, Twitter and Pinterest, I’ve broadcast my name, picture, email, hometown and general movements, if not my specific location, on each of those sites. Of the three, Facebook certainly has the most comprehensive picture of my life for the past seven years—where I’ve been, with whom, what I like and what I’m thinking.

If I wanted to take myself as far off the grid as feasible, simply deactivating the accounts wouldn’t work—Facebook keeps all your information there for you to pick up where you left off. You can permanently delete it with no option for recovery, but some information isn’t stored just on your account—messages exchanged with friends, for example, or any information shared with third-party apps.

If you keep using social networking sites, privacy policies change frequently, meaning that even if you choose the most restrictive privacy settings, you often have to go back and re-set them whenever the company changes its policy. Apps complicate things even further, farming out much of your information to third-party companies with different privacy policies.

Even if you’re vigilant about your privacy settings and eschew apps, your profile is only as private as your most public Facebook friend, said Paul Rosenzweig, a privacy and homeland security expert.

When shopping online, it’s important to check the privacy statements and security policies of the companies you’re using. If possible, purchase gift cards to the specific retailer or from credit card companies and use those to shop, so you don’t leave your credit card information vulnerable to breaches like that of Target.

I know that email is not my friend when it comes to online privacy, but I can’t operate without it.  I use Gmail on Google Chrome for my email, so I installed Mymail-Crypt. It’s one of several “pretty good protection,” or PGP, encryption programs. Using it, my messages appear to be a jumbled bunch of letters until the recipient decrypts it using their private key, which I can save to a key server, like the aptly named Keyserver, where it’s searchable by my email or key ID. I can then link to it on my personal profiles such as Facebook or LinkedIn. People can then send an encrypted email to me using my public key that cannot be read without my private key to unlock it. I’ve also started encrypting my G-Chats using Off the Record chat.

Email can be used against you. Phishers have started to send more sophisticated emails imitating individuals or companies you trust in order to convince you to give up information like your social security number or credit card data. Drew Mitnick a junior policy counselor at digital rights advocacy group Access Now, said you need to be vigilant no matter what you’re doing on the internet.

“Ensure that whoever you’re dealing with is asking for appropriate information within the scope of the service,” he said. In other words, Gap shouldn’t be asking for your Social Security number.

To limit cookies and other data collection during your Internet use, you can open incognito windows in Google Chrome. In incognito mode, the pages you view don’t stay in your browser or search histories or your cookie store—though your Internet service provider and the sites you visit still have a record of your browsing.

Finally, encrypt your hard drive. Privacy laws vary from state to state and country to country so the best way to ensure that you’re protected no matter where you are is to encrypt your computer and be careful not leave it where someone can mess with it, said Mitnick.

Phone footprint

Another source of vulnerability for many people is a smartphone. As long as you have a phone, you’re on the grid—phone companies can triangulate your position using cell phone towers and location services, and they log your calls. Beyond that, though, there are steps you can take to limit information people can access about you using your phone.

First, be judicious when installing apps. Carefully read the permissions an app requires for installation, and if you’re uncomfortable with them, don’t install it! Read privacy policies and terms of use so you know what data the app keeps on you.

Because I have a Windows phone, many of the basic apps (alarms, maps, Internet Explorer, music, and Microsoft Office) are Microsoft apps and use their terms of use and privacy policy, which is pretty good about not sharing my information with third parties. They also delete your account data after you delete their app, though it may take a few weeks.

I have several social apps, such as the aforementioned Facebook and Pinterest, for which the privacy settings are fairly similar to their desktop counterparts—not very private—with the added bonus of them now having access to my location and phone number. It’s entirely possible—and advisable, if you’re trying to leave a minimal footprint—to live without these apps, but I choose not to.

I’m selective about the apps I install on my phone. Aside from the apps that come with the phone and my social media apps, I only have Uber—and that has a lot of access to my phone. According to the app information, Uber can access my contacts, phone identity, location, maps, microphone, data services, phone dialer, speech and web browser. That’s a lot, and not all of it seems necessary—why does Uber need my contacts? Again, though, I chose to compromise my privacy on this one because the convenience, for me, outweighed the risk.

A precaution I’ve always taken is turning off my location service unless I need it. While my cell phone company can still track me, this prevents my apps from accessing my location. I don’t need Pinterest or Facebook to know where I am to get what I want out of the app, so I don’t provide that information to them.

One of the projects Access Now has been working on is “super cookies”—when you use your cell phone, the cell companies can attach unique identifiers to your browsing as you go across multiple sites. Many companies don’t even offer opt-outs. AT&T has now stopped using super cookies, but other companies still do so.

If you don’t already, use two-step verification whenever possible to ensure that no one but you is logging onto your accounts. This process, used by Gmail, has you enter your password and a one-time numerical code texted to a phone number you provide.

Set a passcode to your phone if you haven’t already, and make it something people couldn’t easily guess—don’t use your birthday, for example. I’ve started using random numbers and passwords generated for long-defunct accounts like my middle school computer login that I memorized years ago but that can’t be linked back to me.

Amie Stepanovich of Access Now suggested using four unrelated words strung together for online account passwords—they’re even harder to hack than the usual suggestions of capital and lowercase letters, symbols and numbers.

One final precaution you can take is to encrypt your device. Apple has already started encrypting its phones by default, and Google has promised to do so. Regardless, you can turn on encryption yourself. I have a Windows phone, which does not allow for easy encryption—in fact, I can’t encrypt my SD card at all. To encrypt my phone, I need to log in to Office 365 on my laptop and change my mobile device mailbox policies to require a password, encryption, and an automatic wipe after a number of passcode fails I choose. I then log into Office 365 on my phone to sync the new settings. It’s much more straightforward for an Android—just go to settings, security, and choose “Encrypt phone.”

Off the grid? Not even close

For me – and most people, it’s not feasible to live entirely off the grid. Between my debit card, various online accounts and smartphone, I pour my personal data into company and government databases every day. The trick is to live on the grid intelligently, only providing the information that is necessary and taking steps to protect your devices from unauthorized access.

Privacy: Then and now

Americans value privacy. We close and lock our doors when we get home at the end of the day. We close the blinds when we change clothes so the neighbors can’t peek. If someone wants to visit, they don’t just come over unannounced–they call or text first. In terms of technology, we set passcode locks on our computers and smartphones.

A 2014 Pew Research poll asked people to define “privacy” in one word. The most popular answers were security, secret, personal, alone, information and business.

But today, it’s possible to follow your Internet searches, see who you email, text and call, track your geographical location at all times, monitor your purchases and even track your credit card and phone bills.

The trackers include everyone from family and friends to companies, marketing agencies, the government and law enforcement. From basic information posted on social media, to GPS tracking on your smartphone, people around the world can learn a lot about you from your Internet activity — even when you aren’t intentionally on the Internet. Combining these various components gives them a pretty good idea of what you do, your likes and dislikes, and who and where you are.

You know that nightmare where you’re standing naked in front of an audience? Well, this is the very real 21st century equivalent.

Nearly every app on the modern smartphone is programmed with GPS. Whenever you walk by a WiFi-enabled store, café or home with your Wi-Fi turned on, it registers your device– creating a virtual path of your movement. Do you ever search Google for something, and minutes later see advertisements for it on your sidebar or Facebook? That’s not a coincidence.

In 1965 Gordon Moore, co-founder of Intel, made a prediction known as Moore’s Law: computing power doubles every two years. In other words, computers process large amounts of data faster than ever before. That’s why those Google searches turn into ads so quickly.

Further, the price of data storage is steadily dropping. In 1991, one-gigabyte hard drives cost around $2,700. In 2007, one terabyte (1000x GB) hard drives cost $375. Currently, one terabyte drives cost around $60.

What happens when infinitely faster processing meets infinitely cheaper storage?

“It starts to infringe upon privacy,” said Paul Rosenzweig, cyber and homeland security expert.

So what right do Americans have to privacy?

The Founding Fathers wrote the Fourth Amendment to the Constitution in 1791. It grants citizens the right to be “secure in their persons, houses, papers, and effects, against unreasonable searches and seizures.” Obviously they didn’t have Internet security in mind. Instead, it was a response to Britain’s “general warrant” allowing soldiers total access to search American colonials and their homes.

Let’s translate this to cybersecurity: without a warrant, the government cannot keep surveillance on devices for which individuals have a reasonable expectation of privacy. It also cannot physically take these devices to later use as evidence in court.

Fast-forward nearly 200 years to the Privacy Act of 1974. This legislation came after concerns about the government’s collection, retention and use of personal data. The federal government has a number of databases with information on individuals, both citizens and noncitizens.

The Privacy Act of 1974 set four basic restrictions on the government regarding these databases. First, it required government agencies to show individuals all records kept on them if requested. Second, it set “fair information practices” that agencies must follow when collecting and saving data, such as giving notice that it is collecting the information, how it is storing it and how it is protecting privacy. Third, it restricted the ways information can be shared with other people and agencies. Fourth, it allowed people to sue the government if it violates these regulations.

Even though the Privacy Act was meant to increase government transparency, it contains many exceptions and loopholes.

For example, nongovernment entities, like email and phone providers and app developers are barely restricted when it comes to information collection. They are legally required to disclose in privacy agreements the information they collect (yes, those long, size five-font agreements that very few people bother to read), but that’s about as far as regulation goes. Further, these companies are required to provide government agencies with these user records whenever requested, leaving virtually no choice.

That’s why privacy advocates like Amie Stepanovich encourage companies to only collect information completely pertinent to the functioning of the business.

Stepanovich is senior policy counsel at Access Now, an international digital rights organization.

Stepanovich also urges further safeguards for personal privacy, such as encrypting emails, turning off smartphone app location services and creating secure passwords for online accounts. While these precautions–ranging from simple to very skillful–can certainly aid in Internet security, there’s no surefire way to be anonymous online.

Privacy professionals know that it’s impossible to function in 21st century society without being active online. They also know that, though it means being tracked, keeping location services turned on for some apps can make life easier and, honestly, more fun. Who wants to carry around–and decipher– a map when a GPS provides voice activated turn-by-turn directions? Similarly, think about apps like Starbucks’ that send alerts and coupons every time you’re near a store.

We’re okay with giving Starbucks our location, and maybe even letting Google track our searches, if it means we’ll be notified of sales. But when did we consent to give our purchase histories to credit companies, address histories to data aggregation companies, or travel habits and telephone records to the government?

Americans have mixed feelings about digital surveillance. Many are willing to sacrifice some privacy in exchange for stronger national security. Wouldn’t we all rather the government use cyber tracking to identify and stop terrorists through before they attack?

But specifically after the Snowden leaks, many Americans have become skeptical of the government’s digital surveillance. The Pew Research poll found that 80 percent of adults believe Americans should be concerned about the government monitoring their phone and Internet activity.

Even more are concerned with company surveillance. That same poll showed that 91 percent of adults “agree” or “strongly agree” that consumers have lost control over how companies collect and use their personal information.

While 61 percent said they would “like to do more” to protect their anonymity online, 76 percent consider that a difficult feat.

Others don’t find any reason for online anonymity.

The “I have nothing to hide” argument is a popular one. But critics say no one wants their entire life exposed, no matter how “good” of a person they are.

Too much privacy may enable corrupt behavior. Too little privacy may bring Orwell’s Big Brother to reality. People act differently when they know they’re being watched, and Americans are being watched now more than ever before.

In 1999, SUN Microsystems CEO and founder Scott McNealy famously said, “You have zero privacy anyway. Get over it.” We may be moving that way.
