Privacy Protection Authority, Guide to Privacy-Enhancing Technologies (April 2025): anonymisation does not guarantee protection, especially with AI (Privacy Protection Authority, Guide to Privacy-Enhancing Technologies (PETs), April 2025, section on Anonymisation)
The Authority, summing up an inter-ministerial report, warns that anonymised data can often be re-identified, more so with AI. A holder that removes names from tickets and email should expect the regulator to ask whether the people can still be found, which is the statute's 'reasonable effort' test. The guide sets no certification standard for anonymisation.

“anonymization has significant advantages in protecting the privacy of data subjects, but it does not guarantee complete protection of personal information and the privacy of data subjects, especially in the era of artificial intelligence and its capabilities, which facilitate the re-identification of data subjects from anonymized data.”
