Final answer:
Context-based authentication utilizes additional attributes, such as IP address, location, and time, to verify user identity, offering enhanced security over traditional authentication methods.
Step-by-step explanation:
Authentication that uses the IP address, geographic location, and time of day to help validate a user is known as Context based authentication. This type of authentication evaluates the context in which access attempts occur and leverages additional attributes like location and time to increase security. It's an approach that enhances traditional authentication mechanisms, ensuring that the user's identity is authenticated via multiple factors that are not easily replicated by unauthorized parties.
