Anonymous Opinion Polls

Posted in Scenarios tagged , , at 15:53 by Thomas Groß

A user holds for instance a government-issued identity credential.

The user can participate in an opinion poll and certify his statistical classification with the anonymous credential system, e.g., that the user’s age is between 20 and 25, that she comes from the region Zurich, and that she has not participated in this opinion poll yet.

The user has the advantage that she stays unlinkable, whereas the opinion poll benefits from the certified data quality.
