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

Hashing transforms input data into a fixed-length string of characters, making it challenging to reverse engineer the original information. While hashing is valuable for data integrity verification, it is not suitable for masking sensitive data like personally identifiable financial information.

Salting is a technique that adds random data to input before hashing, increasing security by preventing attackers from easily comparing hashed values. However, salting is primarily used to enhance password security and does not serve the primary purpose of masking sensitive financial data.

Steganography involves concealing data within other non-secret files or messages to avoid detection. While it can be a valuable tool for covert communication, it is not typically employed in the financial industry for masking sensitive data due to the complexity of extraction and potential risks of information loss.
