Homework Help: Questions and Answers: What does the CCValidate object do to improve security?
a) It checks contact information against national databases to verify shipping addresses before shipping
b) Object code that validates credit card numbers looking for attributes that may show errors in the card entry or fraudulent use
c) This is no longer relevant after Chip-and-Pin deployment in the United States
d) CurrentCustomerValidation checks the database to see if the customer has ordered before. If they have they are likely a lower risk
Answer:
First, let’s understand what “CCValidate” is:
- “CC” likely stands for “Credit Card”
- “Validate” suggests it’s performing some kind of verification
Given Options: Step by Step Answering
a) It checks contact information against national databases to verify shipping addresses before shipping
- This option is talking about verifying shipping addresses by matching contact information with national databases.
- This functionality typically deals with address validation, which is more relevant to fraud prevention for physical shipments but not directly related to validating credit card numbers.
- This is not correct answer, as it focuses on address verification, not credit card validation.
b) Object code that validates credit card numbers looking for attributes that may show errors in the card entry or fraudulent use
- This describes credit card validation. The CCValidate object is likely referring to an object that verifies the integrity and correctness of credit card information, such as ensuring the card number follows the correct structure (like the Luhn algorithm) and checking for signs of fraudulent use.
c) This is no longer relevant after Chip-and-Pin deployment in the United States
- While the deployment of Chip-and-PIN has improved security in credit card transactions, credit card validation (like checking card numbers) is still relevant, especially in card-not-present transactions (like online shopping). The introduction of Chip-and-PIN doesn’t make credit card validation objects obsolete.
- This is incorrect, because validation is still relevant even after Chip-and-PIN.
d) CurrentCustomerValidation checks the database to see if the customer has ordered before. If they have they are likely a lower risk
- This option is about checking whether a customer has ordered before, using it as a potential risk assessment.
- However, this functionality seems more like customer validation or customer history checking, not credit card validation.
Final Answer:
Based on the above analysis, the correct answer is:
b) Object code that validates credit card numbers looking for attributes that may show errors in the card entry or fraudulent use
This option directly relates to credit card validation and fraud detection, which aligns with the name and expected function of a “CCValidate” object.
