Student data is protected by privacy-preserving cryptography and authenticated using self-sovereign identity solutions.

This pilot allows university students to trade their academic records in a privacy-preserving way, and recruitment agencies to acquire this data and process it, keeping the student's privacy intact.

Universities produce academic data of students, such as graduation certificates, certificates for each course, and the enrollment status for individual terms. With KRAKEN, a student can export their data into a cloud data wallet and offer it on a data marketplace. By using privacy-preserving cryptography, such as Functional Encryption and multi-party computing, a recruitment service provider can purchase a set of student data and use it for analytics, without invading the privacy of individual students. Additionally, KRAKEN uses self-sovereign identity solutions to always ensure user consent and a link between university/student and their data in a privacy-friendly way.


  • To connect KRAKEN to real university Student-Information System (SIS).
  • To define formats to export and share student data (grades, diploma) in a secure and privacy-preserving way.
  • To allow authentication of students via eIDAS (or SSI identities derived from eIDAS identities) to provide user consent.
  • To allow authentication of student data by using a decentralized SSI ledger.
  • To allow privacy-preserving data analytics on student data using FE and MPC cryptography.
  • To demonstrate the applicability of KRAKEN architecture in general.
  • To verify that design of KRAKEN components can be applied to a real-world use case.

Benefits & beneficiaries

  • Students: using student data for job applications and allowing to share and demonstrate data in a modular way without compromising the rest of the data.
  • University: possibility to exchange student data while ensuring the students' privacy.
  • Recruiter: making analysis of student data sets, e.g., gain insight into the academic performance of an individual student by comparing it with analytic of the data set.
  • Companies: facilitating the search for new talent during the selection processes.


  • Legal challenges: export of student data in a GDPR-compliant way, enabling user consent and privacy.
  • Technical challenges: connect the existing SIS to KRAKEN, define formats; combine the building blocks provided by KRAKEN to encrypt, authenticate and analyze encrypted data; define data analytics system for the student data; connect to one or more data marketplaces; connect to the existing or new SSI ledger.
