An iris scan user can stand a good distance away from the camera and still procure a viable image.

One of the key advantages of retina scans is that the user can stand a good distance away from the camera and still produce a viable image.

A 2D Gabor wavelet filters the iris into multiple partitions known as ________.

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

A facial recognition system can be easily tricked by a ________ picture.

The Interstate Photo System (IPS)has a criminal database containing millions of side-facing mugshot photos of individuals with tenprints on file.

A computer system that captures and analyzes complex data extracted from an image of an iris and compares it to results in a database is known as ________.

The ________ process captures a person's biometric data and stores it in a database for later use.

What is the primary disadvantage of Principal Component Analysis?

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

The FBI has contracted the help of ________ to implement and maintain all facial recognition biometric systems.

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 -Physiological biometrics

Biometric systems use different algorithms and steps to accomplish what each is designed to do.
