History Of Fingerprinting Essay

History Of Fingerprinting Essay-13
ABSTRACT Despite the long history of using fingerprints, some key concerns still remain about the accuracy of identification, the usability of fingerprint systems in different situations, and acceptance by the users.This paper provides a review of those concerns and it provides recommendations for people considering adopting fingerprint recognition systems.

First, there is a mathematical relationship between the corresponding true and false rates so that if one rate is known, the other can be calculated using 100% – X when working with percentages or 1.0 – X when working with proportions.

For example, if the TMR is 98%, the FMR must be 100% – 98% = 2%.

Since I have not found a good venue for it, I am putting it here.

Developers of biometric systems attempt to maximize this measure.

False Acceptance Rate (FAR) / False Match Rate (FMR): this measure represents the degree or frequency where biometric information from one person is falsely reported to match the biometric information from another person. True Rejection Rate (TRR) / True Non-Match Rate (TNMR): this measure represents the frequency of cases when biometric information from one person is correctly not matched to any records in a database because, in fact, that person is not in the database. False Rejection Rate (FRR) / False Non-Match Rate (FNMR): this measure represents the frequency of cases when biometric information is not matched against any records in a database when it should have been matched because the person is, in fact, in the database. These measures of biometric accuracy are interdependent in biometric systems.

The focus is on fingerprint-based systems, but other forms of biometrics will be mentioned as appropriate.

INTRODUCTION One of the most important issues facing technology designers today is security.

With a biometric access control system, the user first enrolls in a system or service and provides a biometric sample, such as a fingerprint.

When they want to use the system later, they must show their biometric characteristic, usually by presenting themselves to some form of scanner, and the characteristic is compared to the previously-stored biometric “template.” If the characteristics match, then the user is granted access to the system.
