What is the problem P3P is designed to solve?
An article by the main developers of P3P states: “Many online privacy concerns arise because it is difficult for users to obtain information about actual Web site information practices…. Thus, there is often a one-way mirror effect: Web sites ask users to provide personal information, but users have little knowledge about how their information will be used.” P3P is not designed to eliminate or reduce the exchange of personal data, but to give the Internet user a way to exercise some discretion over the exchange of that data based on the stated data gathering and use policies of that Web site.
