A survey collects exact GPS coordinates every second when approximate neighbourhood location would meet the stated research need. Which principle is primarily engaged?
Select an answer to reveal the explanation.
Short Explanation
If neighbourhood-level location answers the research question, vacuuming second-by-second exact GPS is overkill—like weighing luggage on a jeweller’s scale when a bathroom scale would do. Data minimisation says take what you need, not the whole satellite trail.
Full Explanation
Article 5(1)(c) requires personal data to be adequate, relevant, and limited to what is necessary in relation to the purposes for which they are processed (data minimisation). Collecting continuous precise GPS when approximate neighbourhood location would suffice for the stated purpose conflicts with that principle and related proportionality expectations in European data protection practice.
