`
`ABSTRACT
`
`A system, method and computer program product that
`utilizes biometric measurements for the authentication of
`users to enterprise resources. The system includes a biomet(cid:173)
`ric server that stores the engine and collections of data
`required by the system to authenticate users. In the present
`invention, it is the biometric policies that determine the way
`or method in which a user is to be authenticated by the
`system. The execution of the biometric policies involves the
`use of one or more biometric templates. Biometric devices
`utilize a scientific technique to identify a user based on
`compared measurements of unique personal characteristics.
`These measurements, called biometric measurements, may
`include, but are not limited to, measurements of finger and
`hand geometry, retina and facial images, weight, DNA data,
`breath, voice, typing stroke and signature. The biometric
`policies of the present invention provide flexibility to the
`level of protection for individual enterprise resources. In an
`embodiment of the present invention, a method of storing
`both biometric templates and digital certificates in a hierar(cid:173)
`chical structure allows for the ease of access to biometric
`templates and digital certificates. In another embodiment of
`the present invention, the system of the present invention is
`implemented as a roaming profile server in a certificate
`authority system.
