  • The CER describes the point where the FRR and FAR are equal. CER is also known as the equal error rate (EER). The CER describes the overall accuracy of a biometric system. As the sensitivity of a biometric system increases, FRRs will rise and FARs will drop.

The Crossover Error Rate (CER) describes the point where the False Reject Rate (FRR) and False Accept Rate (FAR) are equal. CER is also known as the Equal Error Rate (EER). The Crossover Error Rate describes the overall accuracy of a biometric system.

CER is also known as the equal error rate (EER). The crossover error rate describes the overall accuracy of a biometric system. As the sensitivity of a biometric system increases, FRRs will rise and FARs will drop. Conversely, as the sensitivity is lowered, FRRs will drop and FARs will rise.

CER or Crossover Error Rate is the rate where both accept and reject error rates are equal. FER The Failure to Enroll Rate (FER) is the percentage of the population which fails to complete enrollment. EXAMPLE: let us assume we have a fingerprint biometric system. We also, have 100 users. During the enrollment stage 5 users where not able to enroll (e.g we can not establish a fingerprint signature/template for them).

Equal Error Rate (EER) A statistic used to show biometric performance, typically when operating in the verification task. The EER is the location on a ROC or DET curve where the false accept rate and false reject rate (or one minus the verification rate ) are equal. In general, the lower the equal error rate value, the higher the accuracy of the biometric system.

CER equal error rate or crossover error rate (EER or CER): the rate at which both accept and reject errors are equal. The value of the EER can be easily obtained from the ROC curve. The EER is a quick way to compare the accuracy of devices with different ROC curves. In general, the device with the lowest EER is most accurate.

One statistic you will often see cited in vendor material about biometric devices is the crossover error rate (CER). See Figure 5.3. (You may sometimes see this statistic referred to as an equal error rate, or EER.) This is the number that results when the device is adjusted to provide equal Type I and Type II error rates in your environment.

Answer: C. CCTV, mantraps, biometrics, and badges are just some of the items that are part of physical access control. Data classification and labeling are preventive access control mechanisms. Answer: C. The CER (Crossover Error Rate) is used to determine the device’s accuracy. A lower CER means that the device is more accurate.

A biometric sample is the analog or digital representation of biometric characteristics prior to the biometric feature extraction process and obtained from a biometric capture device or a biometric capture subsystem. Example: electronic face photograph. A biometric sample usually is delivered from a sensor, the main component of a biometric capture ...

CISSP DOMAIN #2 ~ Access Control. Contains access control entities (ACEs) that correspond to access permissions. Relationships between subjects and the objects they may access. The likelihood that users will accept the use of a biometric technique. System keeps an accurate audit trail of the users activity.

Biometric Security Jargon: CER, EER, FRR, FAR Biometrics are at the cutting edge of cybersecurity. Get ahead of the game by learning all the jargon associated with the burgeoning field!

Relative Risk Reduction = |EER-CER|/CER In clinical studies it is important to look at both the absolute risk and the relative risk. For example, say the disease A occurs in 1 in 100,000 people but taking drug X reduces the incidence to 1 in 10,000,000. The absolute risk of disease is 0.001%.

FAR and FRR. 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.
