However its main focus is ordinary website, little research has been done for its application in e-commerce websites. E-commerce websites differentiate themselves from those common ones in having some specialties and characteristic data units. The main work of this thesis is to make a fundamentally and detailed study of how the P3P tech can be used in e-commerce. And the P3P protocol is adopted to establish the privacy strategy. Combined with the characteristics of e-commerce websites, some privacy factors of the P3P protocl are redefined and re-established more reasonably to privide greater privacy protection for on-line users.
