Question 1

Your company is developing a new social media app that collects user data. What Privacy by Design principle should be considered to ensure users have control over their personal information?

Minimize data Data minimization Consent and choice Anonymity and pseudonymity

Correct Answer: Consent and choice

The correct answer is consent and choice because it ensures users will have control over their personal data. Anonymity and pseudonymity help to add privacy layers, minimize data means collecting only what is required, data minimization aims to prevent excessive data collection, transparency is about providing clear information regarding data usage, and design and plan for privacy means considering privacy throughout the design process.

Question 2

An e-commerce website needs to improve its privacy policies, while maintaining customer satisfaction. Which Privacy by Design strategy would best suit this goal?

Disclose less information Reduce customer controls Embed privacy into the design Rely only on regulations

Correct Answer: Embed privacy into the design

Embedding privacy into the design ensures that privacy is considered from the beginning of the process, leading to stronger privacy policies while maintaining customer satisfaction. The other options are not suitable as they either disregard privacy or negatively impact the user experience.

Question 3

A mobile app collects both anonymous and personally identifiable information (PII) from users. To maintain Privacy by Design, how should this data be stored?

Store PII and anonymous data separately Store all data together Avoid storing anonymous data Avoid storing PII data

Correct Answer: Store PII and anonymous data separately

Storing PII and anonymous data separately helps ensure privacy by reducing the risk of revealing a user's identity. The other options fail to provide the appropriate level of security or privacy for both data types.
