–Senator Rockefeller Seeks Information About Data Brokers’ Business  Practices  (October 10, 2012)
US Senator Jay Rockefeller (D-West Virginia) has sent letters to nine data brokerage companies, asking them to provide answers to a dozen questions about where and how they gather information, with whom they share the information, and what information is shared. Senator Rockefeller is also asking what level of control individuals have over the information the companies collect. The companies are asked to respond by November 2, 2012. Earlier this year, two US Representatives launched an inquiry into data compilers, and the Federal Trade Commission (FTC) is also looking into some data brokers’ practices.
