Consumer privacy, also known as customer privacy, involves the handling and protection of sensitive personal information that individuals provide in the course of everyday transactions. This involves the exchange or use of data electronically or by any other means, including telephone, fax, written correspondence, and even direct word of mouth.
With the advent and evolution of the World Wide Web and other electronic methods of mass communications, consumer privacy has become a major issue. Personal information, when misused or inadequately protected, can result in identity theft, financial fraud, and other problems that collectively cost people, businesses, and governments millions of U.S. dollars per year. In addition, Internet crimes and civil disputes consume court resources, confound legislators and police departments, and produce untold personal aggravation.
Other consumer privacy features commonly offered by corporations and government agencies include do not call lists; verification of transactions by e-mail or telephone; non-repudiation technologies for e-mail; passwords and other authorization measures; encryption and decryption of electronically transmitted data; opt-out provisions in user agreements for bank accounts, utilities, credit cards, and similar services; digital signatures; and biometric identification technology.
