The PrimeLife Checkout user interface aims at supporting the user in enforcing her privacy preferences in an online purchase process. The user can choose how much privacy protection she wants, and the system visualises what shipping and payment methods are matching with her needs or why the selected methods are not suitable for the protection level of her choice. The interface displays which personal data will be transferred to whom for what purposes in a user friendly way. In most webshops, this information can only be retrieved by reading the shop's full privacy policy. In contrast, the proposed approach informs the user what happens with her data for which purpose while she is entering her data. Thereby it specifically addresses the challenge of a user friendly and more transparent policy display.
