The process in which personal data is altered in such a way that it no longer can be related back to a given individual through an irreversible process. Among many techniques, there are three primary ways that data is anonymized:

Suppression is the most basic version of anonymization and it simply removes some identifying values from data to reduce its identifiability.

Generalization (cohort) takes specific identifying values and makes them broader, such as changing a specific age (18) to an age range (18-24).

Noise addition (salting) takes identifying values from a given data set and switches them with identifying values from another individual in that data set.
