CDPSE - Certified Data Privacy Solutions Engineer Technical Privacy Controls Questions and Answers

Question 1

A research institute needs to analyze medical data to identify disease trends.
For the study's integrity, the data must remain linkable to individuals for longitudinal analysis, but direct identifiers must be removed to protect patient privacy.
However, a mechanism must exist to re-identify a patient if a critical, life-threatening condition is discovered.
Which technical privacy control is MOST appropriate?

Accepted Answer

Pseudonymization

Answer

Anonymization

Answer

Data Scrambling

Answer

Differential Privacy

Question 2

A financial services company wants to provide its development team with a realistic dataset for testing a new application. The dataset must mirror the production database's format and referential integrity but must not contain any actual customer Personally Identifiable Information (PII). Which of the following is the BEST technique to create this test dataset?

Accepted Answer

Static Data Masking

Answer

Dynamic Data Masking

Answer

Transparent Data Encryption

Answer

Attribute-Based Access Control

Question 3

An organization needs to outsource complex data analytics to a third-party cloud service. A strict organizational policy requires that the sensitive data must remain encrypted at all times, including while the third party is actively performing computations on it. Which privacy-enhancing technology would enable this requirement?

Accepted Answer

Homomorphic Encryption

Answer

Transport Layer Security (TLS)

Answer

Symmetric Key Encryption (AES-256)

Answer

Data Hashing (SHA-256)

Question 4

A privacy engineer is configuring a Data Loss Prevention (DLP) system to detect and block emails containing U.S. Social Security Numbers (SSNs), which follow a specific `###-##-####` format. Which technical method is MOST commonly used within a DLP solution to identify structured data patterns like this?

Accepted Answer

Regular expression (RegEx) matching

Answer

Heuristic analysis

Answer

Digital watermarking

Answer

File fingerprinting

Question 5

A social media platform wants to publish a report on user behavior trends without revealing information about any single individual. To accomplish this, their privacy engineering team implements a system that adds a precisely calculated amount of statistical noise to the aggregate query results before publication. This ensures that the presence or absence of any single user's data does not significantly affect the final output. This technique is known as:

Accepted Answer

Differential Privacy

Answer

k-Anonymity

Answer

l-Diversity

Answer

t-Closeness

Question 6

To protect their privacy, they want to provide this proof without revealing their actual date of birth. Which cryptographic technique allows a prover to convince a verifier that a statement is true, without revealing any information beyond the validity of the statement itself?

Accepted Answer

Zero-Knowledge Proof (ZKP)

Answer

Digital Signature

Answer

Secure Multi-Party Computation (SMPC)

Answer

Attribute-Based Encryption (ABE)
