Disclosed are techniques for transforming a biometric template so that each application uses a unique template format. One transformed template cannot be successfully matched to a second template extracted from the same biologic entity unless the second template is transformed so that its format is identical to that of the first template. Thus a template generated in a format corresponding to application A could not be used to authenticate a user for application B because the enrollment database for application B would have a different format than the enrollment database for application A.
