Isn’t location data particularly easy to de-anonymize? I remember reading some research that because people tend to be so consistent with their location, you could deanonymize most people in a dataset with 3 random location samples through the day

This is likely the paper you are referring to:

It states that 95% of people can be identified from just 4 location samples.
