In case we add Fuzzy Name Matching logic to the specification, this will require to have plain text attributes and no hashing.

As KPN we are in favour of Fuzzy Name Matching logic, so we can better deal with imperfect data on either side. Hashing can still be used in cases of Attributes that are really sensitive in terms of privacy, but you have to keep in mind that especially with attributes with a low number of characters it is easy to revert the hashing with a rainbow table.
