AET63 BioTRUSTKey
Fingerprint authentication is the best choice
for highly secure applications for its accuracy, convenience and
cost-effectiveness. A whole system based on this biometric technology may be
expensive, complicated and difficult to maintain, but if you combine it with
smart card technology, such should not be the case.
The smart card-fingerprint reader feature of the
AET63 BioTRUSTKey makes it deployable in applications of different natures, be
it online or offline, for large or small user population, etc. It is an ideal
solution for a broad range of applications, including e-commerce,
physical/logical access control, banking and point-of-sales transactions.
i) Maximum security via multi-factor
authentication and on-board biometric processing
Authentication
is two- or three-way. The BioTRUSTKey verifies something “you have” (smart
card), something “you are” (fingerprint) and something “you know”
(PIN/password). Users carry their fingerprint templates with them and
fingerprint verification authenticates only the smart card user, neutralizing
privacy concerns and security risks posed by dummy fingerprints or stolen
cards. Obviously, anti-security threats are eliminated via more factors of
authentication.
Moreover, the BioTRUSTKey performs fingerprint
template extraction and matching within the device itself – not in the PC – for
maximum security. The 3DES encryption used to protect USB data transmission and
the optional secure access module (SAM) further enhance the security delivered
by the BioTRUSTKey.
ii) Affordable, flexible and scalable system
By storing the encrypted fingerprint template in a smart card, matching just
involves checking the live fingerprint against the stored template. Hence, in
contrast to a traditional fingerprint system, a BioTRUSTKey-based system does
not require extra provision of fingerprint algorithm, database, server, and
network connectivity, lowering both setup and maintenance costs.

Total
cost of ownership is lower in an AET63 BioTRUSTKey-based fingerprint system
Complete local-site authentication implies that,
under normal circumstances, a biometric system can be constructed with just
three components: local PC applications (or remote server applications), any
common smart cards, and the BioTRUSTKey. As only the front-end applications
need modification or replacement, back-end system architecture remains intact,
removing scalability constraints and allowing undemanding system administration
and maintenance.

(1)
Fingerprint image is captured from live scan.
(2) Fingerprint image is converted to template.
(4) Template from smart card is decrypted.
(5) Fresh template is matched against template from smart card.

iii) Easy application development
The BioTRUSTKey API and software development kit – which contains demo
programs, tools/utilities, sample codes and reference manual – provided by ACS
lets developers integrate fingerprint authentication into smart card-based
applications effortlessly without requiring them to have an in-depth knowledge
of biometrics
