... or just do NOT meet pseudonimization at all, but try to enforce
other rules suggested bu GDPR.

Peter put in evidence a concept

"

The GDPR
doesn't say how to do that at all (the legislators were wise enough that
any attempt to do that would result in a mess). So you can't say "the
GDPR says we have to do it this way" (and if your consultant says that
it is probably time to get a different one). You have to consider all
the risks (and yes, an attacker getting access to some or all of the
data is a risk, but a doctor not being able to access a patient's
records is also a risk) and implement the best you can do considering
"the state of the art, the costs of implementation", etc.

"

that would be absolutely right. I'm not forced to use pseudonimysation
if there's the risk to get things worse in a system. I've got to speak
about these"two opposing forces at work" to a privacy expert (maybe
choosing another one, as Peter suggested :-) ) and ask him if it could
be used as a matter of declining pseudonymisation because of
"pseudonimysation puts at risk overall performance or database integrity"

What do you think?
