Development and Evaluation of an Anonymity-Focused Feedback Tool Based on Ring Signatures

A feedback system should be developed for the Blockchain Academy Mittweida, which can store the feedback for the courses offered anonymously and without duplication. It should be possible, without removing the anonymity of the users, to determine whether feedback has already been submitted by a user. For this purpose, the technology of linkable ring signatures was used. This technology allows users to be grouped into a ring and submit feedback anonymously. To determine the interest in and understanding of the solution and technology, a video was created introducing the process and presenting it to a group of subjects. The evaluation showed that there was interest in the presented solution and that the concept could be communicated.
