Documentsubmissionandgradingsystemsarecommonlyused in educational institutions. They facilitate the hand-in of assignments by students, the subsequent grading by the course teachers and the management of the submitted documents and corresponding grades. But they might also undermine the privacy of students, especially when documents and related data are stored long term with the risk of leaking to malicious parties in the future. We propose a protocol for a privacy- preserving, anonymous document submission and grading system based on blind signatures. Our solution guarantees the unlinkability of a document with the authoring student even after her grade has been reported, while the student can prove that she received the grade assigned to the document she submitted. We implemented a prototype of the proposed protocol to show its feasibility and evaluate its privacy and security properties.
