1.2 Biometrics, Smart Cards and Tokens
On-Card Matching
In on-card matching biometric templates, i.e. data sets, are compared
with a previously stored biometric reference template in the smart card
processor itself. This happens in full analogy to the PIN verification where
the entered PIN is sent to the smart card processor and compared on-
card with a previously stored PIN. The advantage of this method is that
the reference template is stored exclusively in the secure smart card pro-
cessor environment, reliably protecting sensitive personal data against
unauthorized access.
Access Rules
An individual access rule is assigned to each elementary file on the smart
card processor. As a consequence, elementary files can be accessed
(read/write/update) by cryptographic authentication, PIN verification, bi-
ometric authentication or a combination of all three.
Applications
The paramount application for biometrics in combination with cards and
tokens is the use in public key infrastructures, where biometric user au-
thentication can be used to enable the cryptographic functions or ser-
vices offered by the smart card processor. Thus, for example, StarSign
Bio Token can be used as a secure signature creating device, that can be
legally tied to the token holder with on-card fingerprint verification.
