P3P aims at providing a simple, automated way for users to gain more control over the use of personal information on websites they browse. P3P is a standardized set of multiple-choice questions about the website's privacy policies. Online customers can answer these questions to select the way their personal information will be handled by the service provider. This snapshot could be read by P3P enabled browsers and set according to the set of privacy preferences of the consumer. P3P not only provides facilitating environment for the consumer to decide, negotiate and firm up the contractual relationship, but also recognizes nine aspects of online privacy. The first five aspects deal with (a) who is collecting this data? (b) Exactly what information is being collected? (c) for what purposes? (d) which information is being shared with others? (e) and who are these recipients? The remaining four aspects focus on the site's internal privacy policies. They include (a) can users make changes in how their data is used? (b) how are disputes resolved? (c) what is the policy for retaining data? (d) and where can be detailed policies found in human readable form?

P3P is software to negotiate privacy agreements between websites and online visitors. It is a kind of social technology that involves not merely technology but also active participation of human beings
