The goal of P3P is to deal with the constant struggle between the need for
WWW content providers to gain information about their readership and the need for these individuals to control the release of this information to others. P3P addresses the twin goals of meeting the data privacy expectations of consumers on the
WWW while assuring that the medium remains available and productive for
E-Commerce. Following the principle of providing consumers notice of site privacy polices, and allowing users to express and act upon their privacy preferences in a flexible manner, one goal enhances the success of the other.
