Section B: Match the Pairs

data minimisation → Only collecting the personal data you need for your purpose

delete_data(survey_results) → Removing the data once your project is finished

A necessary question for a lunch order survey, because it is needed for the purpose → Question: What is your favourite lunch?

An unnecessary question for a lunch order survey, because it is not needed for the purpose → Question: What is your home address?

Class pet vote form: Name, Home address, Phone number, Favourite pet → The form collects a home address and phone number that the vote does not need. Only ask for Favourite pet, and a name only if needed.

Survey finished. Keep all the answers on a USB stick forever, just in case. → Data is kept for no reason and stored unsafely. Store it safely while you need it and delete it when the project is finished.

Section C: Definitions

data minimisation — Only collect the personal data you need for your purpose. Less data means less risk, so skip unneeded questions, store data safely and delete it when finished.

Section D: Fill in the Blanks

purpose = "choose a class sport"
ask("Favourite sport?")

# Keep the survey answers protected
store_safely(survey_data)

# The project is finished
delete(survey_data)

purpose = "choose a class sport"
question = "home address"
needed = False

form = ["favourite sport", "year level"]
for question in form:
    ask(question)

Section E: Spot the Error

B — A home address is not needed to choose a class snack. It is an unnecessary question that adds risk. It should ask only ask("Favourite snack?").

C — Data must be stored safely. A public website lets anyone see the answers. It should be stored in a locked folder.

A — The goal must be a clear purpose, because it decides which data you need. 'Collect everything' is not a purpose. It should be a goal like "choose a sport".

D — Data should be deleted when you are finished with it. Keeping it forever increases the risk. The line should be delete(answers).

C — A parent's phone number is not needed to count lunch orders. Only ask necessary questions, like the allergy question. Unneeded questions should be left out.
