Anonymisation refers to the process of removing or modifying personal identifier, both direct and indirect.
Anonymisation results in anonymised data that cannot be associated with any one individual.
Direct Identifier
A data attribute which, on its own, identifies an individual (e.g. fingerprint) or has been assigned to an individual (e.g. NRIC).
Indirect Identifier
A data attribute which, by itself, does not identify an individual, but when combined with other information, may identify an individual.
De-identification
Removal of identifying information from a dataset. This data could potentially be re-identified.
Re-identification
Identifying a person by recombining de-identified dataset and identifying information.
