Which of the following is the MOST effective method to obfuscate personal data in a public cloud environment?

The correct answer is A. Tokenization. Tokenization replaces sensitive personal data with a non-sensitive surrogate value (a token), allowing systems in the public cloud to operate on the token without ever holding or processing the real data. The actual data is stored securely outside the cloud environment…

Explanation

Tokenization replaces sensitive personal data with a non-sensitive surrogate value (a token), allowing systems in the public cloud to operate on the token without ever holding or processing the real data. The actual data is stored securely outside the cloud environment, typically on-premises. This makes tokenization the most effective obfuscation method in a public cloud context because the sensitive data never resides in the cloud. Digital hashing is one-way and cannot be reversed to retrieve the original value, making it unsuitable for use cases requiring data retrieval. MFA and access controls are security mechanisms, not data obfuscation techniques.
