Comments on the CASIA version 1.0 Iris Data Set

We note that the images in the CASIA version 1.0 iris data set have been edited so that the pupil area is replaced by a circular region of uniform intensity. We recommend that this data set no longer be used in iris biometrics research unless there is a compelling reason that takes into account the nature of the images. In addition, based on our experience with the iris challenge evaluation (ICE) 2005 technology development project, we make recommendations for reporting results of iris recognition experiments.
