What is the difference between physiological biometrics and behavioral biometrics? What are some examples of each type of forensic biometrics?

The FBI has an internal unit called FACE. What does FACE stand for?

How long does it take IrisCode to generate a match?

What is the difference between the enrollment process and the extraction process as it relates to biometric data?

Briefly explain how biometric facial recognition works.

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

Early researchers in facial recognition used ________ to automate facial recognition in an attempt to identify and authenticate individuals from a series of faces.

Prisons and correctional institutions are not using iris-based systems yet to track inmates and efficiently record data that will be shared with members of other various law enforcement communities; however, this technology is predicted to be implemented in the very near future.

Which new feature has been implemented with the NGI?

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