Abstract: The present disclosure relates to method and apparatus for dynamic authentication control at a transit facility having a plurality of checkpoints. The method recites obtaining transit facility data pertaining to operations and schedules of the transit facility. The transit facility data is analyzed to determine a plurality of users expected at the checkpoint, and a number of enrolled and unenrolled users for being authenticated at a biometric authentication system are determined based on the transit facility data. Further, a set of unenrolled users expected to arrive at the authentication system for authentication are estimated using a ROC model. Further, using the ROC model, a false positive identification rate (FPIR) is predicted based on the number of enrolled users and a biometric authentication threshold value. Furthermore, one or more unenrolled users which are expected to be authenticated by the biometric authentication system are determined based on the set of unenrolled users and the FPIR.

Abstract: Computer-implemented methods of automatically identifying, ranking, and processing information obtained from a document, and computerized systems and computer program products related thereto.
