Single Answer
0Chris wants to create a token to substitute for data in a database. Which of the following is not a common attribute for tokens?
Answer Options
A
They don't have exploitable meaning themselves.
B
They are easily reversible to identify the original data, even without the tokenization scheme.
C
They frequently rely on one-way hash functions.
D
Tokens must be mapped to matching original data.
Correct Answer: B
Explanation
Tokens should not be easily reversible. Instead, they should require access to the original tokenization function or a mapping to the original data. Tokens should not have intrinsic meaning or value, and frequently rely on hash functions as part of their generation process to ensure this.
