Privacy Examples in CS Thinking

Start with the recap, study the fully worked examples, then use the practice problems to check your understanding of Privacy.

This page combines explanation, solved examples, and follow-up practice so you can move from recognition to confident problem-solving in CS Thinking.

Concept Recap

The right of individuals to control what personal information is collected about them and how it is used.

Privacy is about deciding who gets to know what about you. In the digital world, your data is collected constantly — privacy is about having a say in that.

How to Use These Examples

  • Read the first worked example with the solution open so the structure is clear.
  • Try the practice problems before revealing each solution.
  • Use the related concepts and background knowledge badges if you feel stuck.

What to Focus On

Core idea: Digital privacy involves trade-offs — sharing data enables useful services but creates risks of misuse, surveillance, and identity theft.

Common stuck point: 'I have nothing to hide' misses the point — privacy is about control over your information, not about having secrets.

Worked Examples

Example 1

easy
What is data privacy? Give three examples of personal data that should be protected.

Solution

  1. 1
    Step 1: Data privacy is the right of individuals to control how their personal information is collected, used, and shared.
  2. 2
    Step 2: Examples of personal data: (1) Name and address, (2) Medical records, (3) Bank account details.
  3. 3
    Step 3: Other examples include email addresses, phone numbers, photos, location data, and browsing history. Even seemingly harmless data can reveal sensitive information when combined.

Answer

Data privacy is the right to control personal information. Examples: name/address, medical records, bank details. All personal data deserves protection.
Data privacy is increasingly important as more personal information is stored digitally. Data protection laws (like GDPR) give individuals rights over how their data is used.

Example 2

medium
Explain how a free social media app can still make money. What are the privacy implications for users?

Practice Problems

Try these problems on your own first, then open the solution to compare your method.

Example 1

medium
List three key principles of the UK GDPR (or similar data protection law) and explain how each protects individuals.

Example 2

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.
