Although these systems are highly accurate, it is equal error rate matlab impossible to create a system that is completely accurate. Crossover error rate, or CER, is measurement that quantifies the error rate in an authentication system. Authentication Errors Two types of errors can occur when determining the

authenticity of an attempt to access an information or security verification system. A false acceptance error occurs when a system incorrectly accepts bad authentication information. A false rejection error occurs when a transaction that has appropriate credentials is incorrectly rejected. System Design Even in optimal circumstances, it is impossible to design an authentication system that eliminates both false acceptances and false rejections. Rather, the levels of false acceptance or rejection are governed by the equal error rate equation sensitivity of the system. The correlation between false acceptance rates and false rejection rates is always negative; that is, as false rejection rates diminish, false acceptance rates go up. System designers are tasked with figuring out the appropriate false acceptance and false rejection rates for each system they design. CER Definition Crossover error rate is defined as the sensitivity calibration point at which an authentication system design has an identical false acceptance rate and false rejection rate. If you plot false acceptance and false rejection rates at different sensitivities on a Cartesian graph, the CER is the point at which the two lines intersect. Crossover error rate is also commonly referred to as equal error rate, or EER. CER Implications A system's CER is used to describe the overall error rate of a system in a single number. The lower a system's CER, the lower the overall error rate of the system. If false acceptances and false rejections are of equal importance in a system, then the CER is the appropriate point at which to calibrate system sensitivity; doing so ensures an equally low rate of acceptance and rejection errors. However, in cases such as bank transactions and location access verification, it is far more important to minimize false acceptances at a cost to false rejections. In s

as EER. Equal error rate (EER) is a biometric security system algorithm used to predetermines the threshold values for equal error rate speaker recognition its false acceptance rate and its false rejection rate. When the rates are equal, the common value is referred to as the equal error rate. The value indicates that the proportion http://www.ehow.com/info_12173088_crossover-error-rate-cer.html of false acceptances is equal to the proportion of false rejections. The lower the equal error rate value, the higher the accuracy of the biometric system. Equal error rate may also be referred to as a crossover rate or crossover error rate (CER).
