What is Crossover Error Rate (CER)

Chapter 418
Encyclopedia of Information Science and Technology, Third Edition
Authentication algorithms need to simultaneously minimize the permeability to intruders, therefore they have to be demanding, and to maximize the comfort level, therefore to be permissive. This contradiction is the base for the optimisation problem in authentication algorithms and the measure of success for the overall precision of an algorithm and of its usability is the Crossover Error Rate (CER), the error rate obtained at the threshold that provides the same False Acceptance Rate and False Rejection Rate.

Keystroke Dynamics and Graphical Authentication Systems
Authentication algorithms need to simultaneously minimize permeability to intruders and maximize the comfort level, therefore they have to be both demanding and permissive. This contradiction is the base for the optimisation problem in authentication algorithms, and the measure of success for the overall precision of an algorithm and its usability is the CER, the value obtained at the threshold that provides the same false-acceptance rate and false-rejection rate.
