Quick Answer

A data broker, also known as an information broker, is a business that aggregates information from public records, online activities, and commercial sources. They then package and sell this data to other companies for purposes like targeted advertising, identity verification, and risk mitigation.

A data broker is an entity that specializes in collecting, aggregating, and selling personal information about individuals, often without their direct knowledge. These companies compile vast datasets from numerous sources to create detailed consumer profiles. The compiled data is then licensed or sold to other businesses for various commercial purposes.

Key Components

  • Data Collection: Gathering personal information from public records (property records, voter registrations), commercial sources (loyalty card programs, purchase histories), and online tracking (cookies, social media activity).
  • Data Aggregation & Analysis: Compiling and analyzing collected data to create detailed profiles of individuals, often segmenting them into categories based on demographics, interests, and predicted behaviors.
  • Data Resale: Selling or licensing these curated datasets and consumer profiles to other businesses for marketing, risk assessment, identity verification, and other commercial uses.

Historical Context or Origin: The practice originated with direct mail marketing companies compiling mailing lists from public records and consumer surveys long before the internet era.

Why Data Broker Matters

Data brokers are central to the digital economy, enabling targeted advertising, personalized services, and financial risk assessment. However, their operations raise significant privacy concerns, as individuals often have little control over or visibility into how their personal data is collected, shared, and used. This lack of transparency can expose individuals to risks including identity theft, discrimination, and data breaches, making it a critical aspect of personal data security and digital legacy.

For families, understanding the scope of a loved one's digital footprint, including where their data might be held by brokers, is a critical part of modern digital estate planning. Platforms like Kinnect help families securely manage and organize digital assets and information, providing a clear framework for navigating these complex issues.
