Hash chain

Changes become traceable

Every audit entry contains the SHA-256 hash of the previous entry. This way the integrity of the audit chain can be verified. Append-only at the database level supports a traceable record of changes.

  • SHA-256 hash of the previous entry in every row
  • Append-only at the database level
  • Verification endpoint for the audit role

Logging

What is logged

Who? When? What? Why? — four questions every audit entry answers.

  • Who?

    User ID and IP address of the person triggering the action.

  • When?

    Server timestamp in UTC.

  • What?

    Before/after state of the affected data row, fully reconstructable.

  • Why?

    Justification as a mandatory field on every manual intervention.

Privacy

Pseudonymisation for legitimate retention

When personal data is no longer needed in clear text, identifying fields can be pseudonymised. Booking-relevant data can be retained where legal retention obligations or legitimate evidentiary purposes apply.

  • Personal fields can be pseudonymised
  • Booking-relevant data can be retained for evidentiary purposes
  • Changes are documented with timestamp, triggering person and scope
