The term "data broker" refers to a company or individual that collects and sells consumer data to other businesses or organizations. This data often includes personal information, buying habits, and online behavior that can be used for targeted advertising or marketing purposes. Data brokers aggregate information from various sources, such as public records, online interactions, and surveys. While this service can provide businesses with valuable insights into potential customers, it raises concerns related to privacy, consent, and data security, prompting discussions around regulations and consumer rights.
