Pseudonymisation and data linking design

Pseudonymised linking of survey and trace data

A keyed-hash pseudonymisation scheme that links survey responses to the same team's Jira and GitLab trace data. Pseudonymised data remain personal data.

Context and problem

An industry study on AI coding tools needs survey responses linked to the trace data of the same team. Pseudonymised data remain personal data, so the link is designed with data protection in mind.

Approach

  • A keyed-hash pseudonymisation scheme links survey responses to the team’s Jira and GitLab trace data.
  • I design the pseudonymisation and data linking step.
  • A large enterprise partner is involved. Partner and contact names are not published.

Status

In progress. No findings are published.
