Exam 7: Forensic Biometrics

Which of the following is one of the key advantages to EBGM?

Iris-based biometric systems have one of the easiest enrollment processes that are available today.

Explain why the FBI's Repository of Individuals of Special Concerns (RISC)is particularly beneficial for law enforcement.

When using IrisCode,a single iris can be stored using only ________ bytes of data.

Iris biometrics may be used after a battle on the deceased to identify if any of the dead are high-ranking insurgents or wanted for acts of terrorism.

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

What function of biometrics would law enforcement be implementing if they wanted to look for a person of interest accused of sexual assault in a large crowd at a sports stadium?

Which facial recognition database would most likely contain the photos of criminals?

Match the word in Column 1 to its definition in Column 2.Each answer can only be used once. A)An internal unit of the FBI that provides face recognition capabilities among other features to support active FBI investigations. B)A form of biometrics that focuses on identifying humans through their unique physiological traits such as fingerprints, hands, iris, retina, and facial scans. C)A biometric system that can distinguish between subjects by analyzing a biometric trait of one person and compares it against an existing database of enrolled traits. D)A technique that creates matrices of human faces and uses complex mathematical equations to generate templates for individual features that are digitally stored. E)Biometric systems popular with law enforcement that are capable of identifying someone out of a crowd by scanning select biometric characteristics into a database. F)The process of capturing a person's biometric data and storing them in a database for later use. G)A technique used in the reconstruction and analysis of a human face through which thousands of stored images of faces are used and placed over the face in question. H)A model-based facial recognition program that uses a sequence of graphs to map the nonlinear relationships of features on the face. I)An appearance-based technique in which an individual's face is placed on a vector and lines from one feature to another are analyzed. J)This module is responsible for finding patterns in the traits extracted by the biometric sensor using mathematical equations. K)A database maintained by the FBI that allows for officers to fingerprint individuals they come in contact with and quickly detect whether or not they pose a threat. L)Responsible for saving all of the raw data produced by feature extraction and putting it into a simple and easy to read format for the system. M)A database maintained by the FBI that contains millions of palm prints to be used in criminal investigations and processes. N)A form of biometrics that focuses on identifying humans through unique behavioral or mental patterns they exhibit such as handwriting, keystrokes, or gait recognition. O)A criminal database containing millions of front-facing mugshot photos of individuals with tenprints on file. P)A process to analyze and store information on a human iris that uses the extracted data from a human iris and processes it through a quantization stage that produces a binary iris code for later comparison. 1)Physiological Biometrics 2)Extraction Process 3)Principal Component Analysis (PCA) 4)Eigenfaces 5)Biometric Identification 6)Elastic Bunch Graph Matching (EBGM) 7)Facial Analysis,Comparison,and Evaluation (FACE) 8)National Palm Print System (NPPS) 9)Interstate Photo System (IPS) 10)Repository of Special Concern (RISC) 11)Behavioral Biometrics 12)IrisCodes 13)Template Generation 14)Biometric Matching or Verification 15)Enrollment Process 16)Linear Discriminant Analysis (LDA)

How long does it take IrisCode to generate a match?

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.

Which of the following features would not serve as a variable for analysis in biometric facial recognition?

For a retina scan,the feature extraction module may use equations that judge the distance between ________ fibers in the eye.

Which module is responsible for finding patterns in the traits extracted by the sensor using mathematical equations?

The ________ is responsible for saving all of the raw data produced by feature extraction and putting it into a simple and easy to read format for the system.

The library of ________ can be superimposed over raw facial images when searching for a facial identification.

One of the main problems with retina biometrics is that viable images can be affected by ________.

The iris begins to form at the ________ stage of pregnancy.

Briefly explain how biometric facial recognition works.

The NIR wavelength band is located within how many nanometers of the electromagnetic spectrum?
