Answer:
Step-by-step explanation:
There are several options for implementing user-based authentication based on physical location and proximity. One option could be to use a combination of two-factor authentication (2FA) and location-based authentication.
Two-factor authentication involves requiring users to provide two different forms of authentication in order to access a system. This could include something the user knows (e.g. a password), something the user has (e.g. a security token), and/or something the user is (e.g. a fingerprint). By requiring two forms of authentication, it increases the security of the system and makes it harder for unauthorized individuals to gain access.
Location-based authentication involves using the user's physical location as an additional factor in the authentication process. This could be done using GPS coordinates or by detecting the user's proximity to a specific location or device (e.g. using Bluetooth). By requiring users to be in a specific location in order to access the system, it adds an additional layer of security.
Combining two-factor authentication with location-based authentication can provide a strong solution for user-based authentication. However, it is important to carefully consider the specific requirements and constraints of the system and ensure that the chosen solution is appropriate and effective.
