Which of the following is an example of a data protection strategy that uses tokenization?

Encryption secures data by converting it into a coded format that is unreadable without a decryption key. While encryption protects data, it does not replace sensitive information with non-sensitive tokens, which is the core principle of tokenization. Thus, this method does not exemplify tokenization.

While removing sensitive data can enhance security, it does not involve the substitution of sensitive information with tokens. Instead, it eliminates the data entirely, which does not align with the definition of tokenization, where a reference to the original data must still exist.

Hashing transforms sensitive data into a fixed-length string of characters, providing a one-way representation that cannot be easily reverted to the original data. Although hashing is a method of securing sensitive information, it does not create a token that can be used in place of the original data, which is essential for tokenization.
