Quick definition: A data broker is a business that collects personal information from various sources, such as public records and online activity, to aggregate, analyze, and sell or license it to third parties.
Explanation
A data broker is a business that aggregates personal information from various sources, such as public records, social media, and purchase histories, to create detailed consumer profiles. These entities act as intermediaries, processing and analyzing vast amounts of data—including demographics, interests, and financial status—to license or sell it to third parties like advertisers, insurance companies, or risk mitigators. Because they rarely interact with the people whose information they handle, their operations often occur without direct consumer knowledge.
A common misconception is that data brokers only deal with publicly available information; in reality, they often source data from private agreements, web tracking, and mobile apps. Another myth is that their activities are strictly used for targeted advertising. While marketing is a primary use, data brokerage also influences credit scores, employment background checks, and even insurance premiums. Furthermore, many believe that being “anonymous” online prevents data collection, but brokers use sophisticated techniques like device fingerprinting and data appending to link disparate pieces of information to a single individual’s profile.
