Biometric Cost Analysis

There are some questions that will help determine the cost benefit analysis of a new biometric system (Cooper). The level of security, the level of reliability, need of backup, the acceptable time for enrollment, level of privacy, and storage needed are things that need to be determined first. Will the system be attended or not? Does the system need to be resistant to spoofing? Will the system operate 24 hours a day? The system will need to be designed based on the individual organization's needs.

Fingerprint devices are low in cost, can be placed on a smartcard, have a low rate of fraudulent users, and are easy to integrate. They operate on the grooves and ridges naturally embedded in the skin to detect the uniqueness of the finger. They also have a higher risk of false rejection and degradation of the fingerprint due to occupation or injury. The error rate is 1/500.

To prevent spoofing, the system would need aliveness detection to ensure rejection of a dead finger or a fake one.

Hand geometry devices are easy to use and integrate into a system, the hand does not significantly change with aging, is used to improve security, accuracy, and convenience for control, time, and attendance, and can work with dirty hands. The hand geometry device measures the parameter, diameter and length, of the hand and fingers. Injury can cause degradation and make the print hard to read. The parameter is unique, but not the hand itself. It does not work well with arthritis, the accuracy is low, and it is fairly expensive. The false….....
