Certified Ethical Hacker (CEH v10) — Question 178

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

Answer options

• 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 positives
• D. Biological motion cannot be used to identify people

Correct answer: B

Explanation

The correct answer is B because the system uses two distinct forms of authentication: the RFID badge as a physical object and the walking pattern as a physical characteristic. Option A is incorrect as it suggests that only one factor is used despite the clear presence of both. Option C is not necessarily true since the effectiveness of the system is not implied to produce high false positives. Option D is wrong because biological motion, such as walking patterns, is indeed utilized for identification in this scenario.
