Thanks for your concern, but it doesn't involve names, these are removed
anyway. I need the variable to link the data to other datasets. But it's
enough to encrypt the variable in a one-way manner. I can do that for both
datasets, get anonymity and am able to link. I cannot link and then destroy
the variable, we will need it later.

Best regards,
-Hendri.
