I love Maria Giggs.

 Then I will give Maria Money.

But I have to confirm that she is Maria Giggs.

I have the Key Word to confirm that she is Maria Giggs.

If I can not confirm that she is Maria Giggs,I will not give that woman or man Money.

Maria Giggs has the Key Word to confirm that she is Maria Giggs too.

Then that has no problem.

Thank you.
