Australian Privacy Principle 2 - Anonymity and Pseudonymity
2.1 An organisation must give individuals the option of not identifying themselves, or using a pseudonym, when dealing with an organisation in relation to a particular matter. This means:
An organisation cannot demand correct identity or proof of identity and,
People must be made aware of their opportunity to do this.
2.2 This does not apply to an organisation if:
It is required or authorised under an Australian law, or a court order, to deal with individuals who have identified themselves, or,
It is impracticable for an organisation to deal with individuals who have changed or withheld their correct name. An example is when goods are to be delivered, especially if a recipient signature is required.
Note: Anonymity involves giving no identifying details (eg: a transaction is anonymous in the instance of paying by cash or making a simple telephone enquiry), whereas pseudonymity involves giving a false name, and can include where some identifying details have been given.
