Example 4

hard
A fitness app tracks users' running routes and shares anonymised data with city planners. Discuss whether this is a good or bad use of data, considering both benefits and privacy risks.

Solution

  1. 1
    Step 1: Benefits: city planners can identify popular running routes and improve pavements, lighting, and safety. This is a legitimate public benefit from aggregated data.
  2. 2
    Step 2: Risks: 'anonymised' data can sometimes be re-identified โ€” running patterns at specific times from specific locations can reveal individuals. Routes might reveal home addresses or daily schedules.
  3. 3
    Step 3: Balanced view: the use is beneficial if properly anonymised (aggregated to large groups, not individual routes) and users give informed consent. The key issues are: was consent given, and is the anonymisation truly effective?

Answer

Benefits: improved city planning. Risks: re-identification of 'anonymous' data. Acceptable if users consent and anonymisation is robust. Privacy and public good must be balanced.
Privacy discussions rarely have clear-cut answers. Evaluating data use requires weighing benefits against risks, considering consent, and assessing whether anonymisation truly protects individuals.
