What term refers to validation of a customer's identity in e-commerce?

• A. PASSWORD VERIFICATION
• B. E-COMMERCE AUTHENTICATION
• C. ID CHECK
• D. DIGITAL SIGNATURE

Answer: (B)

Authentication in e-commerce is the process of confirming that someone is who they claim to be before granting access or processing a transaction. In this context, validating a customer’s identity is best described as e-commerce authentication, since it covers the range of checks used to verify credentials and authorize the user for online activity, such as passwords, one-time codes, or biometrics.

Password verification is a method used within authentication, but the broader term e-commerce authentication more accurately describes the overall process of confirming identity online. An ID check refers to verifying identification documents and is more common in offline or regulated scenarios. A digital signature focuses on the integrity and non-repudiation of a document or message rather than the ongoing validation of a user’s identity in an online shopping session.
