CompTIA SecurityX (CAS-005) — Question 227

A third-party organization has implemented a system that allows it to analyze customers’ data and deliver analysis results without being able to see the raw data. Which of the following is the organization implementing?

Answer options

• A. Asynchronous keys
• B. Homomorphic encryption
• C. Data lake
• D. Machine learning

Correct answer: B

Explanation

The correct answer is B, Homomorphic encryption, as it allows computations to be performed on encrypted data without needing to decrypt it first, thereby preserving data privacy. Options A, C, and D do not offer the same capability; Asynchronous keys relate to encryption methods, Data lake refers to a storage solution, and Machine learning is a method of data analysis but does not inherently protect data privacy.
