A cloud customer is implementing a new analytics platform that processes sensitive customer data. They need to ensure that the data can be analyzed without revealing the original sensitive values, especially when shared with third-party data scientists who do not require direct access to personally identifiable information. Which data security technology is best suited for this requirement?
- ADigital Rights Management (DRM)
- BHomomorphic Encryption
- CData Replication
- DPseudonymization
Show answer & explanationAnswer & explanation
Correct answer: D. Pseudonymization
Pseudonymization replaces sensitive data with artificial identifiers, allowing data to be analyzed and processed without directly identifying individuals, which is ideal for sharing with third parties who don't need original sensitive values. This method maintains data utility for analytics while enhancing privacy.
Why the other options are wrong
- A. Digital Rights Management (DRM) controls access and usage of digital content, rather than de-identifying data for analytical purposes.
- B. Homomorphic Encryption allows computations on encrypted data without decrypting it, which is more complex and typically used when decryption is never desired, whereas pseudonymization focuses on de-identification for analysis.
- C. Data Replication creates copies of data for availability or disaster recovery, but does not inherently de-identify sensitive information.
Pseudonymization
The process of replacing sensitive identifiers within a dataset with artificial identifiers or pseudonyms, making it difficult to directly identify individuals without additional information.
- Enhances data privacy while maintaining data utility for analysis.
- Reversible with the right key or additional information.
- A common technique to comply with privacy regulations like GDPR.
Memory trick: Privacy shields data, but analysis still needs to see the patterns.
