Answer Key

APP 2: anonymity and pseudonymity

Section A: Quick Questions

A — Stay anonymous or use a pseudonym

B — Anonymous use of a service

A — A gaming username like 'NightFox27' that is not your real name

B — False

A — When the law requires it, such as opening a bank account

Section B: Match the Pairs

APP 2 → The principle that lets people deal with an organisation anonymously or using a pseudonym, unless that is impractical or illegal

username = "BlueFox_17" → Using a pseudonym instead of your real name

Anonymous use of a service: a person uses it without giving any identifying details → name = "" # not required

When identity is required: the law or practicality means a real name must be given → if law_requires_id: ask_for_real_name()

signup_form: real_name = required for a public forum → Forcing a real name when anonymity or a pseudonym would work. APP 2 says people should have the option to use a pseudonym unless it is impractical or the law requires ID.

if opening_bank_account: allow_anonymous = true → Allowing anonymous use where the law requires identification. The APP 2 exception applies, so identity must be checked.

Section C: Definitions

APP 2 — Australian Privacy Principle 2: people can choose to stay anonymous or use a pseudonym with an organisation, unless that is impractical or the law requires them to identify themselves.

Section D: Fill in the Blanks

APP 2 lets people stay anonymous

Using a pseudonym means a made-up name

IF lawRequiresID THEN
  ask for real name
ENDIF

Anonymous use is OK unless impractical

IF usePseudonym = TRUE THEN
  DISPLAY username
ENDIF

Section E: Spot the Error

D — When identification is not needed, APP 2 lets the person use a pseudonym. Line 4 should allow(username), not demand a real name.

D — Banks must verify identity by law, so APP 2's exception applies. Line 4 should ask for the full name, not allow anonymous use.

C — The guest session should start when the user says "yes". Checking for "no" starts anonymous use against their choice.

C — If the user gives no name, APP 2 says they can still use a service under a pseudonym. Line 3 should assign a generated guest name, not reject them.

B — An alias is allowed only when the service does NOT need identification. The condition is reversed. It should be RETURN NOT service.needsID.
