When is data truly anonymized? You can probably remember several cases where organizations such as public transport organizations or telecommunication providers published insufficiently “anonymized” data sets resulting in very damaging highly visible news headlines.
This is not to do any finger-pointing, because you know what? Anonymization is really hard! For many real-life use cases it isn’t enough to just substitute names with pseudonyms, or mask some of the values. With a little additional background knowledge it is often possible to identify the individuals you thought had been anonymized.
