Privacy in the era of Big Data

Your identity is your most precious asset. This includes the decisions, emotions, and thoughts that make you unique, ground your perspectives, and connect you with like-minded people. It has also become the hottest commodity in the world.  How to maintain the privacy of your identity while still providing useful services to you as a customer has become a heated debate.

Big data creates stories we couldn’t see before; subtle patterns formed from trillions of gigabytes of data sifting through servers and trickling out of algorithms, finally dispensed as neat and clean business metrics.

  • Doug from Seattle is ready to buy a hybrid. Start sending him financing offers.
  • Zeke in NYC is moving. Send coupons for home improvement stores.
  • Sarah in Cincinnati is likely pregnant. Change the content of her shopping ads to include diapers and cribs.

People have decided to lease out their innate desires in exchange for free content. Every click, like, and retweet is stored and aggregated by data behemoths to understand consumer behavior. We certainly don’t like to pay to view a website, so our behavior is tracked and stored in exchange for content.

Is Privacy a Human Right?

The European Union has made their stance clear with the GDPR’s strict rules on consent to data collection. The legal status of privacy is not so clear-cut in the United States.

To start, let’s get the facts straight: the US constitution does not guarantee anyone a right to privacy. It is implicitly granted in the Bill of Rights, including the right to free speech and the protection from unlawful searches and seizures. Privacy has several components to it:

  • Solitude
  • Secrecy
  • Anonymity
  • Individuality

That is, no one can intrude upon your space, force you to talk, reveal your identity, or impersonate you without your permission. Warren and Brandeis summarize it as “the right to be left alone.”

It’s challenging to translate those ideas into law. The GDPR is one of the most innovative attempts at securing these values as human rights, particularly with the “right to be forgotten.”

Is Privacy Necessary?

That entirely depends on your priorities. If you are a security officer trying to prevent threats, privacy is not a concern. If you are selling private consulting services, confidentiality is crucial to your business.

The issue is not black and white. People feel uncomfortable with being observed without their knowledge or express consent.  Free speech is the right to not only form and voice an opinion but also to keep your opinion to yourself. Imagine a world where everyone was forced to express their opinion on command; it would have a good deal more disagreement! The crucial 2nd element of privacy is the right to secrecy. No one should have to speak unless he or she chooses. The 5th amendment asserts this right.

We humans also crave our alone time. Despite an over-saturation of “interaction” provided by social media, people often feel more disconnected and isolated. Look no further than the failure of the open office as evidence for our need for privacy.

What is Digital Privacy?

All that said, what details are you leaking out by reading this post?

Every Internet enabled device gives clues to its user.

  • Public IP Address – You disclose the IP Address that your current ISP assigns you to access the internet along with your approximate and sometimes accurate city, state, or zipcode.
  • Screen Resolution – You disclose what size your screen is.
  • Browser – You disclose what browser you prefer and all of its extensions.
  • Language – You disclose the text you interpret and the languages you likely speak.
  • Operating System – You disclose your preference for Windows, Android, or iOS as your device.
  • Cookies – Your browser stores information based on the websites you visit. Often that information is used to give you targeted ads.

All of this information can be gleaned just by browsing a web page. What’s even more important is your personal information.  Social media accounts and email addresses are highly sought after by marketers. Their invention is recent, and we treat them trivially. Facebook accounts are often public, and we hand out email addresses to strangers all the time.

As you browse the Internet, websites will ask you to interact with their content on social media. These innocent share and comment plugins are tracking you, pushing your behavior back to Google or Facebook to learn your habits and tastes. It’s easy for the website to collect this information and do whatever they wish.

The result of all of this data harvesting is the advertising bonanza you know so well.

Trust or Power

Any question about your data security previously had one answer: trust whoever holds it. Companies and governments collect data, and citizens have little control.  The GDPR now protects European consumer privacy better than ever before. However, government regulation is not the solution to every problem which poses a new challenge for businesses and private citizens in the modern world.

Encryption

The answer to anonymity is already well known in security circles and has become popular in consumer technologies such as HTTPS and VPN apps.  Encryption is a key in keeping data safe. Strong encryption can keep information private for a long time.

Here’s how it works:

Lets say that you want to privately talk to person b.  Then you’d need a way to:

  1. Confirm that person b is person b.
  2. Eliminate the possibility of anyone eavesdropping or changing the content of your conversation.
  3. Confirm to person b that you are who you say you are.

To do all of this encryption algorithms convert text or data into long strings of characters using complicated equations. The goal is to create code that is virtually unbreakable even with ever increasingly more powerful computers. The only way you can receive the message is by having the key. It all sounds very spy vs. spy, but how is this useful?

It turns out people use encryption principles for many useful everyday tasks. Confirming the identity of an individual on the Internet is a crucial responsibility for all online banking and communication. Citizens can get news directly from journalists or eyewitnesses from anywhere in the world without intermediaries tampering with content.

Information that is correctly encrypted can safely protect the privacy of the individual that owns that information.

Big Data and Privacy can coexist

There is at least one ideal solution that organizations can start doing now:  full encryption for all consumer data collected. From the first interaction all the way to analysis, all consumer data is encrypted and protected to the point that the company cannot easily tie data back to an individual. This is, of course, not possible in every sector, however, it’s the best way forward and a goal to which all big data companies should aspire.

Will encrypting all identifiable information limit the benefits of Big Data?  No.  Looking at data at a massive scale is what gives the best insight.  Consumer identities are unnecessary for analysis which is done on the aggregate.

Who’s On My WiFi is a pioneer in this field by developing an anonymous location analytics technology. Our analytics solution provides a detailed analysis of physical spaces and foot traffic, all without any identifying information on the people who are visiting a location.  Businesses can make data-driven decisions, while customers can browse in anonymity. We like to think it’s the best of both worlds.
