Fair Web Services Certification
Transparency about sharing of data
Services make it clear in the user interface what data is shared with whom and how it is processed.
Rationale: Users need to know what happens to their data so that they can judge who sees which of their data and what is done with it. This is a base for an informed decision if and to what extent to use the service.
Control of sharing of data
Services give users control about what data to share with whom.
Rationale: In addition to transparency of sharing users need to have control about sharing so that they can decide how their data is used.
Default to private
Services never extend sharing data without the explicit approval of the user.
Rationale: Users privacy is protected even if they are inactive or are not paying attention to changes in the service.
Deletion of data
Services must offer users a way to delete all their data.
Rationale: Users can be sure that their data is not used anymore if they decide to leave a service.
