PECB GDPR Exam - Topic 1 Question 5 Discussion

Actual exam question for PECB's GDPR exam
Question #: 5
Topic #: 1
[All GDPR Questions]

Which statement below regarding the difference between anonymization and pseudonymization is correct?

Show Suggested Answer Hide Answer
Suggested Answer: B

According to GDPR Recital 26, anonymization permanently removes any possibility of re-identification, making it irreversible. Pseudonymization, as defined in Article 4(5), is reversible if the correct key or additional information is available. Pseudonymization still qualifies as personal data under GDPR, whereas anonymized data falls outside the scope of GDPR.

I remember discussing how anonymization is a stronger form of data protection than pseudonymization, but I can't remember the exact details of how they differ.

I’m a bit confused about the definitions. I thought anonymization was about making data completely untraceable, but I can't recall the specifics on pseudonymization.

I think I remember that anonymization means you can't trace the data back to individuals, but I'm not sure if pseudonymization is really reversible or not.

This is a tricky one, but I'm leaning towards B. Anonymization is about making data unidentifiable, while pseudonymization is about replacing identifiers in a way that can be traced back. Just don't ask me to explain it in plain English!

Hmm, I'm pretty sure B is the correct answer. Anonymization makes the data completely unidentifiable, while pseudonymization just replaces identifiers with a code that can be traced back to the original data.
