Pattern-based incorporation of privacy preferences into privacy policies: negotiating the conflicting needs of service providers and end-users

Data protection during processing an end-user's personal data is one of the service provider's main responsibilities. According to data protection regulations, e.g. the European General Data Protection Regulation, an informed consent to privacy policies and a proper purpose specification in privacy policies are the essential legal foundation for the processing of personal data on the Internet. Privacy policies must make end-users aware of their rights and possibilities when using an online or offline service. While privacy policies affect both the service provider and end-user, current visualization methods and a missing voice of the end-user cause an asymmetry between the implementation of the needs of both parties. We aim to reconcile this asymmetry and propose a pattern for a modifiable privacy policy whose practical implementation can benefit both, service providers and end-users. We name our pattern "privacy policy options". With the "privacy policy options" pattern applied to WhatsApp, we demonstrate the application of our approach.
