Abstract
A method of registering biometric data is disclosed wherein a number of instances of input biometric data are accepted from a new user during a registration process. Each of these data samples are compared against existing templates to identify those templates posing a significant risk of confusion with a data sample. Those templates are identified and information relating to those templates is stored with the enrolled template of the new user. When a user is identified as the new user, the system automatically verifies that the data sample does not also result in identification as one of the identified templates.
