Everything about FAR and FRR [1]
Anyone who wants to assess or compare the performance of biometric security systems cannot ignore these terms. In this article we explain what FAR and FRR mean, how they impact on each other and how they affect a system’s security level and user convenience.
– False Acceptance Rate (FAR): the percentage of identification instances in which unauthorised persons are incorrectly accepted.. – False Rejection Rate (FRR): the percentage of identification instances in which authorised persons are incorrectly rejected.
The point at which the lines intersect also has a name: the Equal Error Rate (EER). This is where the percentage of false acceptances and false rejections is the same.
What is better- a Type I or a Type II error? [2]
Importance of minimizing errors based on the problem/dataset.. Type I error refers to non-acceptance of hypothesis which ought to be accepted
When someone scans their fingers for a biometric scan, a Type I error is the possibility of rejection even with an authorized match. A Type II error is the possibility of acceptance even with a wrong/unauthorized match.
We will take three scenarios to understand how the problem statement and situations are so important in this context. Scenario/Problem Statement 1: Providing access to an asset post a biometric scan.
CISSP Study Guide: Identification and Authentication [3]
Identification and authentication are integral to an access control system.. – Identification is carried out by the user or service supplying the system with user IDs.
Both the sender and recipient can verify the other as a legitimate user with whom they’re trying to communicate. If persons wishing to communicate or exchange information cannot verify each other trust is compromised, deterring further activity.
– An object the user has been granted possession of, such as a smart card.. Of the three authentication methods, passwords are the most widely used, though they’re the easiest to decode as many users will use passwords that are easy to remember, such as an anniversary or birthday.
False Reject Rate (FRR) [4]
Probability that the system fails to detect a match between the input fingerprint template and a matching template in the database. It measures the percent of valid inputs which are incorrectly rejected
The False Reject Rate (FRR) is the ratio of the number of false rejections divided by the total number of transactions. FRR is calculated by dividing the number of false rejects by the total number of transactions
The false reject rate (FRR) measures how well your system can identify legitimate users. It is the percentage of times that a user is incorrectly rejected by your system

The False Rejection Rate: What Do FRR & FAR Mean? — RecFaces [8]
The False Rejection Rate: The Importance of FRR & FAR Rates. One of the main drivers for interaction between digital technologies and end-users is convenience
Which indicators determine the convenience and safety of biometric security systems? Is there a factor that impacts them both? How can you upgrade your own security methods using biometric technology? Learn more in this article.. – Is it Possible to Compare the FRR & FAR of Different Biometric Systems?
One of the tasks of a security system is the recognition of unauthorized users trying to gain access. The flip side of this process is the likelihood of incorrectly identifying an authorized person as an impostor
Biometric security jargon: CER, EER, FRR, FAR [9]
A few weeks ago I wrote about how there are many ways to summarize the operating characteristics of a test. The most basic terms are accuracy, precision, and recall, but there are many others
Biometric security uses False Acceptance Rate (FAR) for the proportion of times a system grants access to an unauthorized person. False Rejection Rate (FRR) is the proportion of times a biometric system fails to grant access to an authorized person
The system has parameters that can be tuned to adjust the FAR and FRR. Adjust these to the point where the FAR and FRR are equal

Your company implemented a biometric system that matches fingerprints against the model database to control access to the computer room. An IT engineer is authorized to enter the computer room by the management but rejected by the system
Kindly be reminded that the suggested answer is for your reference only. It doesn’t matter whether you have the right or wrong answer
Wentz’s book, The Effective CISSP: Security and Risk Management, helps CISSP and CISM aspirants build a solid conceptual security model. It is a tutorial for information security and a supplement to the official study guides for the CISSP and CISM exams and an informative reference for security professionals.
False Acceptance Rate (FAR) and False Recognition Rate (FRR) [11]
The false acceptance rate, or FAR, is the measure of the likelihood that the biometric security system will incorrectly accept an access attempt by an unauthorized user. A system’s FAR typically is stated as the ratio of the number of false acceptances divided by the number of identification attempts
A system’s FRR typically is stated as the ratio of the number of false recognitions divided by the number of identification attempts. Here, we discusses some general principles of biometric recognition systems, describes different classification errors and explains how the quality of two systems can be compared objectively.
Identification is the process of trying to find out a person’s identity by examining a biometric pattern calculated from the person’s biometric features.. In the identification case, the system is trained with the patterns of several persons
Using Biometrics for Authentication [12]
If you’re planning to take the SY0-401 version or the SY0-501 version of the Security+ exam, you should have a basic understanding of how systems and users provide credentials to verify their identity. Users at your organization currently use a combination of smart cards and passwords, but an updated security policy requires multifactor security using three different factors
More, do you know why the correct answer is correct and the incorrect answers are incorrect? The answer and explanation is available at the end of this post.. Authentication is often simplified as types, or factors, of authentication
– Something you are, such as a fingerprint or other biometric identification. – Somewhere you are, such as your location using geolocation technologies
Errors in Biometric Systems [13]
In this chapter, we are going to talk about failure and error rates in a biometric system. It is important to know about these errors, to be able to test if a biometric system is performing as expected and to compare different biometric systems.
Biometric decisions are mostly based on a numerical score and threshold. This applies not only to the comparison (Section Biometric Comparison) but also to some stages of enrollment (Section Enrollment), especially when it comes to Quality Assurance (QA).
The enrollment process consists of multiple steps, mainly (Figure 25):. At each step of enrollment, one or several types of failures can occur

Hypothesis testing, type I and type II errors [16]
Hypothesis testing is an important activity of empirical research and evidence-based medicine. A well worked up hypothesis is half the answer to the research question
The present paper discusses the methods of working up a good hypothesis and statistical concepts of hypothesis testing.. Karl Popper is probably the most influential philosopher of science in the 20thcentury (Wulff et al., 1986)
The popularity of Popper’s philosophy is due partly to the fact that it has been well explained in simple terms by, among others, the Nobel Prize winner Peter Medawar (Medawar, 1969). Popper makes the very important point that empirical scientists (those who stress on observations only as the starting point of research) put the cart in front of the horse when they claim that science proceeds from observation to theory, since there is no such thing as a pure observation which does not depend on theory
False Acceptance Ratio [17]
The false acceptance ratio (FAR) is a unit used to measure the average number of false acceptances within a biometric security system. It measures and evaluates the efficiency and accuracy of a biometric system by determining the rate at which unauthorized or illegitimate users are verified on a particular system.
FAR primarily helps determine the accuracy level of a biometric security system. FAR is calculated by dividing the number of false acceptances by the number of identification attempts
This means that the biometric system will allow 10 percent, or 1 out of each 10 false attempts, to access the system.
IT Security Concepts [18]
Biometrics verifies an individual’s identity by analyzing a unique personal attribute or behavior, which is one of the most effective and accurate methods of verifying identification. Biometrics is a very sophisticated technology; thus, it is much more expensive and complex than the other types of identity verification processes.
These are traits that are physical attributes unique to a specific individual. Fingerprints are a common example of a physiological trait used in biometric systems.
This is based on a characteristic of an individual to confirm his identity. Physiological is “what you are” and behavioral is “what you do.”
