Internet passports are designed to let people decide what personal information they will allow to be released to websites. A variety of technologies are involved with Internet passports, including the Platform for Privacy Preferences (P3P), the Internet Content and Exchange standard (ICE), and the Open Profiling Standard (OPS). The passport lives inside a web browser. A user fills out a profile in the browser, determining what information can be made available to websites, such as name, address, occupation, username and password, and age. The user also decides which type of information about his surfing habits can be shared among websitesand which can't. In this instance, the person has decided that information about what news stories he reads can be shared, but not information about what products he buys.
