Exam 7: Forensic Biometrics

The only disadvantage that PCA poses is that a full ________ face image is needed to be a viable sample.

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

Who was the first researcher who attempted to identify someone using the iris?

Applicants that are being entered into an iris-based biometric system need how many photographs taken of their eye?

Discuss why iris biometrics are preferred over retina biometrics.

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 comparing 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 it 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 quantitation stage that produces a binary iris code for later comparison -Principal Component Analysis (PCA)

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

Explain the collection steps in gathering biometric data.

The ________ system compares a suspect encountered by law enforcement against a repository of sex offenders, wanted persons, suspected terrorists, and other high-risk individuals.

Which process captures a person's biometric data and stores it in a database for later use?

The FBI's internal unit ________ contains civil photos from state and federal government databases, such as visa applicant photos and selected states' driver's license photos.

Which facial recognition technique uses a sequence of graphs to map the nonlinear relationships of features on the face?

The ________ generation module 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.

Which of the following facial recognition biometric techniques is NOT among the most widely accepted today?

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

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

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

Briefly explain how an iris biometric system works.

One of the benefits of facial recognition biometrics is that instead of having to rely on citizens identifying and reporting suspects that they may or may not come in contact with, a camera and computer system can accomplish the entire process without human intervention.
