Rounding and nulling are examples of which type of data de-identification function?

Answer options

• A. Hashing
• B. Tokenization
• C. Masking
• D. Salting

Correct answer: C

Explanation

Rounding and nulling are techniques used to obscure specific data points while preserving the overall dataset's usability, which is characteristic of masking. Hashing, tokenization, and salting serve different purposes, such as securing data through transformation or adding randomness, and do not specifically involve the techniques of rounding or nulling.
