Question 1

One of the problems with facial recognition biometrics is that software has a difficult time analyzing and identifying faces from grainy and low-resolution photographs.

Accepted Answer

Facial recognition software relies on clear, high-resolution images to accurately analyze and identify facial features. Grainy and low-resolution photographs lack the detail necessary for effective recognition, leading to difficulties in analysis and identification.

Question 2

Applicants that are being entered into an iris-based biometric system need how many photographs taken of their eye?
A)One
B)Two
C)Three
D)Four

Accepted Answer

For an iris-based biometric system, typically, a photograph of each eye is taken, making the total two photographs. This ensures that both irises are captured for identification purposes, as the patterns in the iris are unique to each individual and even between one's own eyes.

Question 3

The FBI has an internal unit called FACE. What does FACE stand for?
A)Facial Analysis, Comparison, and Extrapolation
B)First Analyze, Comparison, and Evaluation
C)Facial Analysis, Comparison, and Evaluation
D)First Analyze, Comparison, and Extrapolation

Accepted Answer

FACE stands for Facial Analysis, Comparison, and Evaluation, which is a unit within the FBI that focuses on facial recognition and analysis.

Question 4

Which of the following would NOT be considered a physiological biometric?
A)Fingerprint
B)Handprint
C)Iris
D)Voice

Accepted Answer

Physiological biometrics are based on measurements and data derived from the physical body, such as fingerprints, handprints, and iris patterns. Voice, however, is considered a behavioral biometric because it can change over time and is influenced by both physical and behavioral factors.

Question 5

There are three main functions of biometrics.

Accepted Answer

Biometrics primarily serves two main functions: identification and verification. Identification is determining who a person is, and verification is confirming a person's claimed identity.

Question 6

A significant advantage of automated facial recognition, as compared to other different of biometrics, is that it requires subjects to participate.

Accepted Answer

Automated facial recognition can capture and identify individuals without their active participation or even awareness, unlike other biometric systems that often require conscious action from the subject, such as fingerprinting or iris scanning.

Question 7

Popular equipment includes NIR (near infrareD)cameras or SLR (single lens reflex)cameras to gather data from a human face.

Accepted Answer

The answer of Popular equipment includes NIR (near infrareD)cameras or...

Question 8

Before Touch ID, data was not significantly more vulnerable to password attacks, even when a phone had been stolen or breached.

Accepted Answer

Before Touch ID, data was more vulnerable to password attacks because traditional passwords and PINs can be easier to guess, hack, or obtain through social engineering compared to biometric authentication methods like Touch ID, which provide an additional layer of security.

Question 9

Linear discriminant analysis is considered a model-based facial recognition.

Accepted Answer

The answer of Linear discriminant analysis is considered a model-based...

Question 10

The military has been using biometrics for an extended period of time to keep sensitive information secure and to prevent espionage and theft in regards to valuable military assets.

Accepted Answer

Biometrics, which include methods like fingerprint recognition, facial recognition, and iris scanning, have been utilized by the military for years to enhance security measures, control access to sensitive information, and protect valuable assets from unauthorized access or espionage.

Question 11

Which scanners are largely outdated and considered to be too intrusive to be practical in real-world applications?
A)Iris
B)Retina
C)Pupil
D)Cornea

Accepted Answer

Retina scanners are considered largely outdated and too intrusive for most practical applications. They require a close-up scan of the eye's retina, which many people find uncomfortable, leading to the preference for less intrusive methods like iris scanning.

Question 12

The first process that each biometric system must perform is known as the enrollment process.

Accepted Answer

The enrollment process is the first step in a biometric system where the system captures and stores the biometric data of an individual for the first time, creating a reference template for future matching.

Question 13

Which of the following is one of the key advantages to EBGM?
A)A full facial image is required
B)Its extreme precision and accuracy
C)It works even with blurry or grainy images
D)Relatively inexpensive compared to other analyses

Accepted Answer

EBGM (Elastic Bunch Graph Matching) is known for its extreme precision and accuracy in facial recognition, which is one of its key advantages.

Question 14

Which of the following technologies is replacing retina biometrics because it is an all-around better technology and is functional for both law enforcement and business security?
A)Iris biometrics
B)Pupil biometrics
C)Sclera biometrics
D)Cornea biometrics

Accepted Answer

Iris biometrics is considered an all-around better technology compared to retina biometrics because it is less intrusive, provides quick and accurate results, and is suitable for a wide range of applications in both law enforcement and business security.

Question 15

Which of the following systems is highly beneficial for law enforcement safety in that it allows for officers to fingerprint individuals they come into contact with quickly to detect whether or not they pose a potential threat?
A)MorphoTrak
B)IPS
C)NPPS
D)RISC

Accepted Answer

RISC (Rapid Identification System) is a system used by law enforcement to quickly identify individuals through fingerprint scanning, helping to determine if they pose a potential threat.

Question 16

The combination of a mobile device and a fingerprint scanner has become a reality for law enforcement agencies.

Accepted Answer

Many law enforcement agencies now use mobile devices equipped with fingerprint scanners to quickly identify individuals in the field.

Question 17

The iris is responsible for obtaining a clear picture of what a person is actually seeing.

Accepted Answer

The iris controls the size of the pupil and thus the amount of light that enters the eye, but it is the lens that focuses light onto the retina to form a clear image.

Question 18

Like iris biometrics, facial recognition scans are intrusive and cannot gain data in a way that is comfortable and hygienic for its users.

Accepted Answer

Facial recognition technology is generally considered less intrusive compared to iris biometrics, as it can often be performed at a distance without direct contact, making it more comfortable and hygienic for users.

Question 19

The NIR wavelength band is located within how many nanometers of the electromagnetic spectrum?
A)100-300
B)400-500
C)700-900
D)1000-1100

Accepted Answer

The Near-Infrared (NIR) wavelength band is located within the 700-900 nanometers range of the electromagnetic spectrum, which is just beyond the visible light spectrum.

Question 20

NGI provides a positive or negative identification of the suspect.

Accepted Answer

The answer of NGI provides a positive or negative identification...
