Comprehensive and Detailed Step by Step Explanation: Data maskingobscures 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. Encryptionis unrelated because it protects data in transit or at rest but does not address how it is displayed. Tokenizationreplaces data with a token but is more relevant for storage and transactional systems, not screen data. Scrubbingrefers to cleansing datasets but does not address this scenario.
