US 2004/0179718 A1 · Card-type biometric identification device and method therefor

Abstract

A card-type biometric identification device includes a biometric sensor, an operating/processing module, a remote transceiver, and a rechargeable battery. The biometric sensor reads the biometric data of a holder. The operating/processing module stores a random-code generating program, personal data, and authorized biometric data of the holder, and may then receive and process to-be-identified biometric data. After judging that the to-be-identified biometric data substantially matches with the authorized biometric data, the module generates and outputs a to-be-identified code by the random-code generating program. The remote transceiver outputs the personal data to a host system to enable the host system to generate an authorized code by the random-code generating program, which is stored in the host system and corresponds to the personal data. Comparing the authorized code with the to-be-identified code may judge whether or not the to-be-identified holder is an authorized holder.

Claims22

Dependent claims

A card-type biometric identification device for identifying whether or not a to-be-identified holder beside a host system is an authorized holder, the host system stores personal data of the authorized holder and a random-code generating program corresponding to the personal data, the card-type biometric identification device comprising:

a biometric sensor for reading and outputting authorized biometric data of the authorized holder and to-be-identified biometric data of the to-be-identified holder;
an operating/processing module capable of receiving, processing and storing the random-code generating program, the personal data and the authorized biometric data only once, and then of receiving and processing the to-be-identified biometric data multiple times, wherein the operating/processing module generates and outputs a to-be-identified code by the random-code generating program after the to-be-identified biometric data is judged to substantially match with the authorized biometric data;
a remote transceiver for outputting the personal data to the host system to enable the host system to generate an authorized code according to the random-code generating program corresponding to the personal data, wherein it is judged whether or not the to-be-identified holder is the authorized holder by comparing the authorized code to the to-be-identified code;
and
a rechargeable battery for providing power for the operating/processing module, the biometric sensor and the remote transceiver.

A card-type biometric identification method for identifying whether or not a to-be-identified holder of a card-type biometric identification device beside a host system is an authorized holder of the card-type biometric identification device, personal data of the authorized holder and a random-code generating program corresponding to the personal data being stored in both of the host system and the card-type biometric identification device, and the card-type biometric identification device storing authorized biometric data of the authorized holder, the method comprising the steps of:

reading and outputting to-be-identified biometric data of the to-be-identified holder to an operating/processing module;
enabling the operating/processing module to process the to-be-identified biometric data and judge whether or not the to-be-identified biometric data substantially matches with the authorized biometric data;
enabling the operating/processing module to generate a to-be-identified code according to the random-code generating program stored therein if the to-be-identified biometric data substantially matches with the authorized biometric data;
and
causing the operating/processing module to output the personal data to the host system to enable the host system to generate an authorized code according to the random-code generating program corresponding to the personal data, wherein comparing the to-be-identified code to the authorized code may judge whether or not the to-be-identified holder is the authorized holder.
