A high security identification card includes an on-board memory for stored biometric data and an on-board sensor for capturing live biometric data. An on-board processor on the card performs a matching operation to verify that the captured biometric data matches the locally stored biometric data. Only if there is a positive match is any data transmitted from the card for additional verification and/or further processing. Preferably, the card is ISO SmartCard compatible, and the security processor used for storing and processing the protected biometric data is functionally separated from the ISO SmartCard processor by a firewall that not only secures the protected data against unauthorized access, but also secures the software and encryption keys which produces the encoded portion of the verification message, thus protecting the entire verification process from malicious external attack via the ISO SmartCard interface. Real-time feedback is provided while the user is manipulating his finger over the fingerprint sensor, thereby facilitating an optimal placement of the finger over the sensor. The card may be used to enable communication with a transactional network or to obtain physical access into a secure area. |
