1. A method for securing access to protected applications, the method comprising:
- receiving a plurality of predetermined biometric templates;
transforming said predetermined biometric templates to generate a plurality of transformed biometric templates;
storing said transformed biometric templates in a storage;
receiving a first biometric template;
transforming said first biometric template to create a first transformed biometric template;
comparing said first transformed biometric template with said stored transformed biometric templates.

Abstract
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.
