A retailer holds customer personal data and wants to follow good data protection practice. Which action best reflects the principle of data minimisation?

Collecting only the personal data needed for the stated purpose reflects data minimisation. The principle requires that data be adequate, relevant and limited to what is necessary. Encryption is a security measure and access by customers is a subject right, while indefinite retention conflicts with the principle.

  1. AKeeping all customer data indefinitely in case it is useful later
  2. BCollecting only the personal data needed for the stated purposeCorrect
  3. CEncrypting all customer data stored on laptops
  4. DAllowing customers to view the data held about them

Explanation

Data minimisation means collecting and holding only the personal data that is adequate and necessary for the stated purpose. Encryption relates to security, and allowing access relates to data subject rights; keeping data indefinitely contradicts minimisation and storage limitation.
