AET63 BioTRUSTKey

Fingerprint authentication is the best choice for highly secure applications because of the accuracy and convenience it provides. A major drawback in integrating this biometric technology into a whole system includes expensive and complicated maintenance, however combining it with the smart card technology makes all the difference necessary to downscale the cost of maintaining the system without compromising security.

With the AET63 BioTRUSTKey, smart card and fingerprint technologies are combined into one secure platform that caters to applications in different environments— whether online or offline, whether for small or large user populations. 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 either two-way or three-way. The AET63 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. Anti-security threats are further eliminated via more factors of authentication. Moreover, the AET63 BioTRUSTKey ensures maximum security by performing fingerprint template extraction and matching in the device itself and not in the PC, which is vulnerable to security attacks. The 3DES encryption used to protect USB data transmission and the optional secure access module (SAM), further enhance the security delivered by the AET63 BioTRUSTKey.

ii) Affordable, flexible and scalable system

By storing an encrypted fingerprint template in the smart card, matching merely 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 for fingerprint algorithm, database, server, and network connectivity, thus lowering both setup and maintenance costs.

iii) Easy application development

The AET63 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. r.
