BIOMETRIC-BASED ACCESS TO SECURE RESOURCES WITH DUAL AUTHENTICATION

摘要

A biometric-based access mechanism implements a dual authentication scheme. An authorized user enrolls in the system by generating a set of biometric data from which at least first and second templates have been generated and stored in an authentication server. When the user at a client later seeks to obtain access to a protected resource, a new set of biometric data and templates are generated at the client, using the same functions that were used to generate the first and second templates during the enrollment process. If the authentication server matches the template received from the client, the authentication server exports to the client a template that must then be matched with the template being held in memory before authentication is complete and access to the protected resource at the application server or other host.
