From the document: "Businesses collect, use, and sell consumer data for their commercial benefit, but consumers may be unaware of how their data are being collected and used. Consumers generally do not have the ability to stop the collection of their data, verify data accuracy, or maintain privacy. As technologies change, consumers may not always know what data businesses are collecting about them, or how those data are used and shared. Advanced, internet-connected technologies help businesses gather increasing amounts of personal data, track online behavior, and monitor consumers' locations and activities, intensifying concerns about the privacy and accuracy of consumer data. Over the past decade, we have found that the increasing collection and use of personal information raises concerns related to consumer privacy and protection. Concerns also exist about adverse effects resulting from potential bias and a lack of transparency. The U.S. does not have a comprehensive privacy law governing the collection, use, and sale or other disclosure of consumers' personal data. Existing federal consumer protection laws may not apply to some newer uses of consumer data."
