A passport does not make every detail public
Annex XIII distinguishes public information and information with restricted access. Different information may be available to authorities, parties with a legitimate interest and other eligible actors.
Classify data before publishing
- Identify the legal access category of each field.
- Separate public information from restricted technical or commercial data.
- Determine how an applicant’s identity and purpose are assessed.
- Arrange controlled access, changes to rights and handling of requests.
Do not invent an access policy in place of the rules
An internal confidentiality preference does not override a required disclosure. Equally, a passport requirement does not justify publishing every factory document. Use the current EU provisions and their further implementation to determine who should receive which information.
Discuss security and continuity
Access controls must work alongside data accuracy, availability and continuity. The future AccuZegel portal’s access arrangements will be specified before it handles customer or battery data.
