Exam SY0-601 topic 1 question 825 discussion

D. The data is relabeled. Tokenization does not maake the fileds irreversible, use symmetric algorithms, or restrict access to authorizeed card holders. It simply chnages the data into a different format that has no value outside the context of the transaction.

Answer A: Option D, “The data is relabeled,” could be considered a simplified description of tokenization. In tokenization, sensitive data is replaced with non-sensitive substitutes, or “tokens,” which could be seen as a form of “relabeling.” However, this description lacks the specificity of option A, “The fields are irreversible,” which more accurately captures the security benefit of tokenization. In tokenization, without access to the original tokenization system, the process is irreversible, meaning the original sensitive data cannot be derived from the tokens. This is a key aspect of how tokenization protects sensitive data. So while D is not entirely incorrect, A is a more complete and accurate answer.

i think it is A. the question asks very specific on credit card tokenization, which is irreversible. it is not talking about tokenization in genenral though.

I'd choose A. Because that's what Tokenization does. When we use credit card to make a payment, tokenization will create a fake credit card number that Irreversible to the original credit card number. Eventhough, attacker can capture that fake credit card number but that credit card number can't be reuse.

I agree with Payu. The process of tokenization is designed to be irreversible, meaning that it should not be possible to mathematically reverse the token back into the original data. This irreversible nature ensures that even if someone gains unauthorized access to the tokenized data, they cannot retrieve the original sensitive information from the tokens alone. Therefore, this characteristic of tokenization enhances the security of stored credit card information.

Tokenization replaces sensitive data with a token, and this token can be used as a functional placeholder for the original data.

for those who picked A, that's called Anonymization.

D. The data is relabeled. Tokenization means that all or part of data in a field is replaced with a randomly generated token. The token is stored with the original value on a token server or token vault, separate to the production database. An authorized query or app can retrieve the original value from the vault, if necessary, so tokenization IS a reversible technique.

Tokenization is an essential process that entails substituting sensitive information, like credit card numbers, with a distinct token. The term "irreversible" signifies that the process is one-directional, rendering it highly challenging to convert the token back to the original credit card number. This guarantees that even if the tokenized data is compromised, the original credit card information stays secure and cannot be readily accessed.

D. The data is relabeled Tokenization is a data protection method that involves replacing sensitive information (such as credit card numbers) with unique tokens or references. In tokenization, the data is relabeled

D. The data is relabeled None of these answers are really good, but D is the closest.
