Data Brokers sell data to Businesses

There has been an unprecedented growth of a multi-billion dollar industry of data brokers that operates in the glooms with virtually no oversight.

Data Brokers collect, analyze and package some of your most sensitive personal information and sell it as a commodity to businesses, advertisers, other data brokers and even the government without letting them know.

Information collected by Data Brokers include-

  • Name, Age, and Gender
  • Present and previous Address
  • Handphone numbers
  • Email address
  • Marital status
  • Age of Children
  • Property ownership
  • Political preferences
  • Income details
  • Educational details and more

The extent of data collection can spread to monitoring important life events like marriage, baby, relationship status, getting a divorce and more.

How do Data Brokers collect your personal information

Data Brokers can be termed as specialist firms across the web. To gather information about users and throw up related ads, they host a slew of third parties that observe who comes to the site and build up a digital profile about them.

You may argue that how it is possible to track your web movement when you traverse from one site to another. Data brokers, apply tools such as Cookies, web beacons, e-tags and a variety of other tools. Cookies, widely used on desktop computers, are small pieces of code that are dropped on a user’s browser. A Web beacon is a small transparent graphic image that is placed on a website or in an email and used to monitor the browsing or email-sending behavior of the user

Using the above monitoring techniques, they summarize what sites users you have visited, what you have shopped for, what time you are likely to shop, and so on.

1] Anonymous data sets can be de-anonymised

As more information gets attached to cookies and devices, it becomes easier to identify users. With necessary information, anonymous data sets can be de-anonymised. Researchers say that only two data points is enough to identify more than half the users. Hence, data brokers easily hitch other personal details too, such as your income, the size of your home, number of children, property type – rented or owned.

2] Other information sources for Data Brokers

Easily available information in the form of Government records and other publicly available information are other sources of data feeders for Data Brokers. For instance, the motor vehicles department may sell information like your name, address, your vehicle types to data companies, although only for certain permitted purposes, including identity verification.

Similarly, publicly available voting records, which include information about your party registration and how often you vote, can also be bought and sold with restrictions and only to some third-parties.

3] From your smartphone

Most free smartphone apps that you happily install on your phone ask for permission to access your address book or other folders. We quickly and happily give it, since we are eager to use the app. This is how the apps get access to your data and steal your contacts details and more.

The latest example is the popular Sarahah app which uploads your entire address book – and the developer has accepted this as a fact!

Non-Conventional Data brokers

Non-Conventional Data brokers are those entities who are not into data collection business, but their core business is such that they have access to data worth billions of dollars.

Take a look:

1] Banks

Much of our sensitive financial information is shared with banks we transact. When using their banking services, we are bound to share information that includes,

  • Social Security number
  • Account Balances and Transaction History
  • Credit History and Investment Experience
  • Home and office address
  • Information related to job, email, phone number, and more

Although Banks are required to comply with the Consumer Privacy Policy, which necessitates them to inform users about data collection and use and allow those users to opt-out of some, there are loop-holes to bypass the process.

During third party audits and credit checks, much of the user financial information is shared with third-parties, effectively turning your bank into a data broker. Banks also shares its customer’s data points with companies for marketing / improving customer service experience.

2] Social websites

There is a price to pay if something comes as free and you are welcomed only after you hand over your personal information. Free email, free OS, free app to connect with friends and family and free search, all come with data compromise.

Social networking sites like Facebook and Twitter collect heaps of personal information, including ages, friends, and interests, when you sign up and spend time browsing. Much of the information is collected without you being aware of it. For instance, Facebook’s “Like” and Twitter’s “Tweet” buttons which most websites embed in order to allow visitors like/follow their page carry a code that allows the social-networking companies to track users’ movements even if they do not click those buttons.

Google is by far the #1 search engine and its other free services like Gmail, Google Maps, rank among the best and most preferred in the industry. However, there is a trade off in exchange of the free services that Google provides. A lot of your personal information is collected by the Search giant to dish out personalized, targeted ad experiences.

Your name, email address, telephone number, credit card information, your usage pattern, your communication with other websites using AdWords and other Google technologies, your device information, search queries, and more, is collected by Google to know more about you. Google through Chrome also stores information in your browser via local browser storage to know your preferences.

Consumer data collection company, Datalogix, entered into an agreement with Facebook, to track whether Facebook users who see ads for certain products actually end up buying them at local stores.

Microsoft had to come out time and again and defend itself on what information it collects. The company clearly spells out on what it collects, which includes Name, Contact information, Login credentials, Demographic data, Payment credentials, and more.

Contrary to its privacy policy, which says that it reads everything, the company says that it does not read the text of the email, but only the line and body. Thankfully, it does not sell ads aggressively with the data it collects.

Data Brokers industry is growing rapidly

According to a report, Figure estimated for the year 2012 reveals that the data broker industry generated $156 billion in revenues,” a sum that is “more than twice the size of the entire intelligence budget of the United States Government.” So you can imagine the size of this market today in 2017!

Although there are numerous data brokers active in the Europe, the European data broker landscape is not comparable to the US market in terms of market size. The European revenues of large data brokers, such as Acxiom, LexisNexis, amount only to a fraction of their overall revenues.

The firm Acxiom, publicly traded on the NASDAQ, does more than $1.1 billion annually offering its analytical services and is only one of the many other companies in the US.

  1. I’m gonna be surprised if someone here actually doesn’t know that. I mean, in most websites, the first thing that pops up to your screen is a warning sign that talks about cookies and how you must agree with their use if you want to browse that website.

    As you mentioned above, applications on Android smartphones will also warn you that they collect data. Pretty much any kind of service that we use will notify us on what data they collect.

    So, it’s not surprise that some of them are willing to sell that data.
