Which of the following solutions would most likely be used in the financial industry to mask sensitive data?

Tokenization is the most suitable solution for masking sensitive data in the financial industry because it replaces sensitive data (like credit card numbers) with a unique, non-sensitive token. This token can be used in transactions without exposing the original data, significantly reducing the risk of a data breach. Hashing creates a fixed-size string from input, but it's one-way and irreversible, making it unsuitable for data that needs to be retrieved. Salting adds random data to a password before hashing, primarily for password security, not data masking. Steganography hides data within other non-sensitive data, which is not its primary purpose for masking sensitive financial information.
