Greg and Dan talk with Dave Johnson of Pearl Technology about data brokers, what they are, and how they collect, organize, and share information about consumers. He explains how businesses use data brokers, the types of personal information that can end up in their databases, and how certain services work with these companies to help remove people's information and reduce unwanted spam. He also discusses what consumers should know about their digital footprint and ways to better understand where their information may be going online.
