Personal information was a secondary concern, often limited to name and address for shipping purposes. Today, that data encompasses a digital mosaic of our lives — from shopping habits to social media content, health statistics, and beyond. The transformation of personal data into a commodity is not just a cultural shift. It represents a profound change in the economic fabric of society. A 2019 report by the Interactive Advertising Bureau found that the data-driven advertising industry contributed $139.8 billion to the United States economy in the previous year alone. This astonishing figure underlines the weight of personal data as a tradable asset. 

The Value of Personal Data

Personal data encompasses any information relating to an identifiable individual. In the digital sphere, this ranges from basic demographics to intricate behavioral insights. For businesses, this data is gold. It informs product development, tailors marketing strategies, and drives customer engagement. A study by the World Economic Forum estimated the value of personal data in Europe alone to be €1 trillion by 2020, signaling its lucrative nature.

The surge in the value of personal data has given rise to tools designed to protect it, with Virtual Private Networks being among the most prominent. The use of  VPN serves as a secure tunnel for internet connectivity, shielding users from unwarranted surveillance and data harvesting practices. Market research from the Global Web Index indicates that over a quarter of internet users worldwide have used a VPN for digital protection, underscoring its vital role in the contemporary quest for digital privacy.

Data Collection Mechanisms

Personal data collection is a process that takes place across various platforms and devices. Here’s how it works:

Online Forms: When you sign up for a new service, purchase a product online, or even enter a competition, you fill out online forms. These forms collect your name, address, email, and sometimes your preferences and interests.

Social Media Activity: Your activity on social media platforms — the posts you like, the things you share, and the accounts you follow — is tracked. This information helps build a profile of your interests and behavior.

IoT Devices: Devices connected to the internet, like smartwatches, home assistants, and smart fridges, collect data on your usage patterns and preferences.

The role of cookies and tracking pixels is more technical but essential to understand:

Cookies: These are small data files stored on your browser when you visit websites. They remember your preferences and login information, making your next visit easier. However, they also track the websites you visit and the products you look at, which informs companies about your browsing habits.

Tracking Pixels: These are tiny, invisible images placed on a website or in an email. They notify the server when you’ve accessed content, providing insights into your online behavior.

Lastly, mobile apps are significant data collection sources. They often ask for access to your location, contacts, and other personal information on your phone. With location data, apps can know where you go, how long you stay, and even predict where you might head next. All this data is valuable for companies that want to understand, predict, and influence your behavior.

The Data Marketplace

In the data marketplace, collected information is a tradeable asset. Data brokers and aggregators harvest and compile data, often without direct user consent. The sale and exchange of this data occur in a nebulous legal and ethical space, where regulations struggle to keep pace with technological advancements.

Use of Personal Data in Targeted Advertising

Personalized advertising is a technique where companies use individuals’ data to present ads that align with their interests and online behavior. The data-driven approach relies on user information to tailor marketing messages likely to resonate with the target audience. According to a study by McKinsey, businesses harnessing advanced customer analytics experience a 126% profit gain over those that don’t.

This method is effective because it connects products with consumers who have already shown an interest in similar items. For instance, someone who frequently searches for books may receive recommendations for new releases in their favorite genres, increasing the likelihood of a purchase.

By focusing on interested consumers, companies optimize their advertising budgets, as they are not spending money to reach disinterested parties. This targeted approach not only saves money but also increases the chances of converting views into sales.

In essence, the strategic use of personal data in advertising allows businesses to engage with potential buyers meaningfully, leading to higher sales and a better return on investment for marketing campaigns.

The Dark Side of Data Commoditization

The commoditization of personal data is not without risks. Privacy breaches and identity theft are on the rise, with the average cost of a data breach reaching $3.86 million, as reported by the Ponemon Institute. High-profile data breaches have exposed vulnerabilities, emphasizing the need for robust data protection measures.

Consumer Awareness and Response

Consumers are increasingly aware of how their data is used. In response, many have turned to ad blockers and privacy tools. A survey by Pew Research Center showed that 79% of adults are concerned about how companies use their data.

Regulatory Responses and the Future of Data Privacy

Regulations like the General Data Protection Regulation (GDPR) and the California Consumer Privacy Act (CCPA) represent significant strides toward protecting personal data. These regulations challenge businesses to adapt, balancing economic interests with consumer rights. Looking ahead, the future of data privacy is set to be a dynamic negotiation between innovation and the protection of individual rights.

The Role of Technology in Protecting Privacy

Technological innovations promise to enhance data privacy. Blockchain technology, for example, offers a decentralized approach to data management, potentially empowering users to control their personal information.


The commercialization of personal data has transformed the digital economy, offering both opportunities and challenges. As the landscape evolves, a collaborative effort among consumers, businesses, and regulators is essential to harness the benefits of data-driven innovation while safeguarding privacy rights. The collective call to action is clear: prioritize privacy, uphold transparency, and foster trust in the digital economy.
