Which type of verification is NOT mentioned among the four types of verification?

• A. Basic
• B. Digest
• C. Secret URL
• D. API Key

Answer: (D)

The type of verification that is not mentioned among the four types of verification is the API Key. While many systems utilize API keys for authentication and authorization purposes, they do not fall into the typical categories associated with data verification methods in this context. The other types mentioned—Basic, Digest, and Secret URL—are standard methods that focus on how data is verified and transmitted during requests, particularly in web services and APIs. Basic and Digest verifications refer to methods that involve encoding credentials using specific schemes to authenticate users. Secret URL verification typically involves signing a URL to prevent tampering and ensure that it is valid and secure for a specified period. In contrast, API keys serve as tokens that allow access to an application's programming interface but do not specifically verify the integrity of data in the same structured way as the other three methods, which are designed primarily around the security and verification of transmitted data.
