Steve, a scientist who works in a governmental security agency, developed a technological solution to identify people based on walking patterns and implemented this app

roach to a physical control access.

A camera captures people walking and identifies the individuals using Steve-s approach.

After that, people must approximate their RFID badges. Both the identifications are required to open the door.

In this case, we ca

n say:

A. Although the approach has two phases, it actually implements just one authentication factor

B. The solution implements the two authentication factors: physical object and physical characteristic

C. The solution will have a high level of false po

sitives

D. Biological motion cannot be used to identify people
