Abstract
Methods and apparatus are provided for evaluating the classification performance of different risk engine models. A classification performance of an authentication method is evaluated by obtaining performance data for an authentication method; generating a receiver operating characteristic (ROC) curve for the obtained performance data; determining a partial area under the curve (pAUC) for a region of interest of the ROC curve; and providing a performance score for the authentication method based on the pAUC. The region of interest comprises, for example, a region of false positives. The pAUC is optionally standardized using a McClish Transformation. The performance score for the authentication method can be compared to a second performance score for a second authentication method. A confidence level can optionally be provided for the comparison based on a natural test statistic.
