Concerns have led to consumer privacy laws in most countries, especially in the European Union, Australia, New Zealand and Canada. Notably, among developed countries, the United States has no such law and relies on corporate customer privacy disclosed in privacy policies to ensure consumer privacy in general. Modern privacy law and regulation may be compared to parts of the Hippocratic Oath, which includes a requirement for doctors to avoid mentioning the ills of patients to others—not only to protect them, but to protect their families— and also recognizes that innocent third parties can be harmed by the loss of control of sensitive personal information.
