This does not reference hashing, which can be an irreversible and destructive operation. As such, it can remove the “relating” part - i.e. you’ll no longer be able to use the information to relate it to an identifiable natural person.
In this context, if I define a hashing function that e.g. sums all ip address octets, what then?
