method for exchanging privacy practices between websites and users.
concepts:
- user defines preferences in a database (e.g. what personal data may be given away by its browser)
- services define practices (e.g. what kind of data it will collect)
example:
a user visits a website with information about movies played. if the user does not provide any personal information, she gets a general list of all movies played. if she allows her browser to send her address to the website, it will return a page with more detailed information about movies played in the area where she lives.
P3P defines the information that will be exchange between the browser and the server. information can be stored on the server and/or on the client side, so this is also replacement for cookies.

- resource discovery
- content rating
- to express intellectual property rights
