pseudonymization

Definition(s):

  a particular type of de-identification that both removes the association with a data subject and adds an association between a particular set of characteristics relating to the data subject and one or more pseudonyms. Typically, pseudonymization is implemented by replacing direct identifiers with a pseudonym, such as a randomly generated value.
