AC 428 Register re. UK Data Protection Act ?

[Classicus]

To clarify the overall position regarding our UK Data Protection Act, as some non UK owners might like to see their names included with their car on the AC 428 Register but knowing nothing about the international legal issues involved, does anyone know if and how this might or might not affect the UK based 428 Register ?
   
   Obviously the safest and best rule is never to mention any owner's names at all.
   
   Thanks in advance [:)]
