Carol wants to obfuscate data that is contained in her database. She wants to be able to refer to the data elements without having the actual data exposed. What type of obfuscation option should she select?

Tokens replace data with a value that is linked specifically to the data, allowing it to be referenced and used without the field being exposed. Encryption is not used for this purpose, data masking hides elements of a data field like digits from a credit card number, and data randomization is not an obfuscation method.
