Which of the following techniques is used to obscure sensitive data displayed on screens, such as showing *** for parts of SSNs, while still allowing legitimate use of the data?
Correct Answer: A
Comprehensive and Detailed Step by Step Explanation:
* Data masking obscures sensitive data displayed on screens, such as masking certain characters (e.g., showing *** for parts of SSNs).
* It allows legitimate use while protecting the data from being misused or stolen.
* Encryption is unrelated because it protects data in transit or at rest but does not address how it is displayed.
* Tokenization replaces data with a token but is more relevant for storage and transactional systems, not screen data.
* Scrubbing refers to cleansing datasets but does not address this scenario.
