6.4.4. Security and Privacy

This section must discuss security and privacy issues related to URN assignment and use. It needs to consider:

1. Information disclosure risks: Whether URNs themselves may leak sensitive information
2. Forgery and tampering: How to prevent URNs from being forged or illegally modified
3. Access control: Whether control is needed over who can create or resolve URNs
4. Privacy protection: Whether URNs contain personally identifiable information
5. Secure transmission: Security considerations for URN transmission over networks

Even if there are no special security or privacy concerns, this must be explicitly stated.
