The document summarizes the key findings of a study conducted by the Federal Trade Commission (FTC) on the practices of nine major data brokers. The FTC found that data brokers collect vast amounts of personal information about consumers from various sources without consumers' knowledge. Data brokers then use this data to create consumer profiles and inferences, and develop products for marketing, risk mitigation, and people search that are sold to various clients. While these products provide some benefits, the FTC raised concerns about consumers' lack of awareness and control over their personal data held by brokers. The report makes legislative and best practice recommendations to improve transparency and consumer choice.
