Biometric Performance Standards and Metrics

Here are the engineering aspects you need to take into consideration when implementing a Biometric System:

First, you need to be concerned with the enrollment and verification times of the biometric technology you are planning to purchase.  In broad terms, enrollment can be defined as the process of registering your employees into the biometric system, and verification can be defined as the biometric system actually confirming the identity of your employee, and granting them access to entry.

You want to acquire a biometric system which will result in very rapid verification times.  Otherwise, you could potentially have employees that will be waiting in line to be verified, which could then cause them to have disdain for the system.

The enrollment process usually takes longer than the verification process, because your employees will have to enroll a few times, in order to insure enough unique features from their biometric is captured by the system.

Another aspect you need to take into consideration is if your biometric system will operate in either a standalone or networked mode.  For example, suppose you have purchased and installed four fingerprint scanners at four different access entry points at your place of business.

In a stand alone mode, the fingerprint devices will act like their own computer-each device will conduct its own enrollment and verification transactions, as well have its own database for storage of the biometric data.  In a networked environment, all of the fingerprint scanners will be connected to a central server, where  the enrollment and verification transactions will take place, as well as storage of the biometric data.

We will look at more engineering designs in tomorrow’s blog.
