Earlier quoted context omitted.
What security concerns? Of a person telling people where you live? Are the homes of Danish prime ministers secret?
I think some context is being lost in a literal translation. I think they mean secret as in unlisted where their records aren't accessible in public government databases. The same protection you would get if you were stalked for example.
Stalking falls under the broad category of harassment in my eastern european country. I feel as if this would be a non issue given an official police warning. At most.
