What data obfuscation technique relies on a lookup table that allows you to match the data you want to secure to a randomly generated value to ensure that the actual value is not easily accessible?

Tokenization commonly uses randomly generated values that are assigned to replace existing known values. The token is stored in a lookup table, allowing the token to be checked against the table if needed. Hashing relies on a hash function, which is not mentioned here; randomization is not a data obfuscation technique; and masking replaces some or all of a sensitive field with a replacement character to ensure the data is unreadable when displayed.
