Question 1

Who was the first researcher who attempted to identify someone using the iris?
A) Matthew Turk
B) Alex Pentland
C) John Daugman
D) J. H. Doggart

Accepted Answer

D

Question 2

Out of the various forms of behavioral biometrics,which of the following is the least accurate?
A) Voice recognition
B) Keyboard dynamics
C) Gait recognition
D) Handwriting

Accepted Answer

Gait recognition, which involves analyzing an individual's walking pattern, is considered the least accurate form of behavioral biometrics. It is often affected by external factors such as the environment, footwear, and speed of walking, making it less reliable than other forms of behavioral biometrics such as voice and handwriting recognition.

Question 3

Which of the following features would not serve as a variable for analysis in biometric facial recognition?
A) Cheekbones
B) Neck
C) Chin
D) Widow's peak

Accepted Answer

Neck is not a facial feature and therefore would not be used in biometric facial recognition.

Question 10

What is the most commonly used type of behavioral biometrics?
A) A person's gait or walk
B) Handwriting
C) Speech
D) Keyboard typing

Accepted Answer

The answer of What is the most commonly used type...

Question 11

Modern techniques of facial recognition can be attributed largely to the work of which researcher(s):
A) Alphonse Bertillon
B) Matthew Turk
C) Alex Pentland
D) Both B and C

Accepted Answer

Alphonse Bertillon developed a system of anthropometry that was used for identification purposes in the late 19th and early 20th centuries. However, modern techniques of facial recognition are largely attributed to the work of Matthew Turk and Alex Pentland. Turk is known for his work on eigenfaces, a technique used for facial recognition, while Pentland is known for developing a computer vision approach to facial recognition known as "FaceNet". Therefore, both B and C are the correct choices.

Question 12

What is one of the new features that has been implemented with the NGI?
A) Voice recognition
B) Gang affiliation
C) Sex offender registry status
D) New Tenprint system

Accepted Answer

The new feature implemented with the NGI is the New Tenprint system which allows the capture and storage of all ten fingerprints instead of just two, making it a more accurate and reliable system. Voice recognition, gang affiliation, and sex offender registry status are not mentioned as new features implemented with the NGI.

Question 13

How long does it take IrisCode to generate a match?
A) 2-3 seconds
B) 20-30 seconds
C) 2-3 minutes
D) 4+ minutes

Accepted Answer

IrisCode typically generates a match in 2-3 seconds.

Question 14

Which process captures a person's biometric data and stores it in a database for later use?
A) Enrollment process
B) Initiation process
C) Extraction process
D) Collection process

Accepted Answer

The enrollment process captures a person's biometric data (such as fingerprints, facial features, or iris scans) and stores it in a database for later use in authentication or identification processes. This process is a crucial step in establishing a biometric system.

Question 15

Which of the following is not considered a behavioral biometric?
A) Handwriting
B) Keystroke patterns
C) Gait Recognition
D) Facial scan

Accepted Answer

Facial scan is actually considered a physiological biometric, not a behavioral biometric. Behavioral biometrics are based on an individual's actions or behaviors, such as keystroke patterns, gait recognition (how someone walks), and handwriting. Physiological biometrics, on the other hand, are based on an individual's physical characteristics, such as facial features, fingerprints, and iris scans.

Question 16

When using biometrics,if the sensor does not find a positive match to a human within its database,what happens?
A) An alarm is generated
B) Law enforcement is notified
C) It locks the attempted user out
D) The system captures the new biometric data

Accepted Answer

When a biometric sensor cannot find a positive match within its database, it typically locks the attempted user out of the system. This is because the purpose of biometric authentication is to verify the identity of a known user, and if the identity cannot be verified, access should be denied. While some systems may capture the new biometric data to add it to the database for future use, this is not always the case and is not the best choice. An alarm is typically only generated in situations of unauthorized access or security breaches, and notifying law enforcement would be an extreme measure that is not necessary in this scenario.

Question 17

Which facial recognition technique uses a sequence of graphs to map the nonlinear relationships of features on the face?
A) CCTV
B) EBGM
C) LDA
D) PCA

Accepted Answer

EBGM (Elastic Bunch Graph Matching) is the facial recognition technique that uses a sequence of graphs to map the nonlinear relationships of features on the face. CCTV (closed-circuit television) is a type of video surveillance technology, while LDA (Linear Discriminant Analysis) and PCA (Principal Component Analysis) are machine learning techniques used for feature extraction and dimensionality reduction, but not specifically for facial recognition.

Question 18

Which of the following facial recognition biometric techniques is not among the most widely accepted today?
A) PCA
B) CCT
C) LDA
D) EBGM

Accepted Answer

PCA (Principal Component Analysis), LDA (Linear Discriminant Analysis), and EBGM (Elastic Bunch Graph Matching) are among the most widely accepted facial recognition biometric techniques. However, CCT (Color Coherence Vector) is not as widely accepted and utilized in comparison.
