E-P3P privacy policies and privacy authorization

Abstract

Enterprises collect large amounts of personal data from their customers. To ease privacy concerns, enterprises publish privacy statements that outline how data is used and shared. The Platform for Enterprise Privacy Practices (E-P3P) defines a fine-grained privacy policy model. A Chief Privacy Officer can use E-P3P to formalize the desired enterprise-internal handling of collected data. A particular data user is then allowed to use certain collected data for a given purpose if and only if the E-P3P authorization engine allows this request based on the applicable E-P3P policy. By enforcing such formalized privacy practices, E-P3P enables enterprises to keep their promises and prevent accidental privacy violations.
