What is the difference between de-identification/pseudonymization (CCPA) and anonymization (GDPR)?

When data is anonymized, ideally the reference to a person is completely removed. The process is also not reversible. Examples of anonymized data are statistics on population figures, an average income of a specific group of people, or survey results for clinical studies.

With pseudonymization/de-identification, on the other hand, the reference to a person is retained. Information such as name, age, telephone number is not deleted, but merely replaced by a pseudonym. Here, storing a username in the database as person 184875 would be an example.
