Abstract

An efficient exchange of messages in a system for authenticating access to a base device is facilitated through the selection of a particular biometric template from among a plurality of biometric templates. Rather than transmitting the template to a peripheral device, an indication of a location of the particular biometric template within the plurality of biometric templates is transmitted to the peripheral device. At the peripheral device, once the indication of the location and a biometric candidate are received, the particular biometric template may be located and compared to the biometric candidate. Finally, an indication of a result of the comparing may be transmitted to the base device.

Claims

1. A method of facilitating, at a base device, an efficient exchange of messages in a system for authenticating access to said base device, said authenticating based on a data set comprising a plurality of biometric templates, said method comprising:

transmitting a command message to a peripheral device for forwarding to a memory device physically connected to said peripheral device, said command message requesting said data set, said command message including an instruction to said peripheral device to maintain a copy of data received in a response message from said memory device.

2. The method of claim 1 wherein said command message comprises a command application protocol data unit according to ISO 7816.

3. The method of claim 2 wherein said transmitting said command application protocol data unit comprises employing an extension to an existing application programming interface for communicating with said memory device.

4. The method of claim 3 wherein said employing said extension comprises inserting said instruction to said peripheral device into said command application protocol data unit.

5. A computing apparatus employing a system for authenticating access to said computing apparatus, said authenticating based on a data set comprising a plurality of biometric templates, said computing apparatus adapted to:

transmit a command message to a peripheral device for forwarding to a memory device physically connected to said peripheral device, said command message requesting said data set, said command message including an instruction to said peripheral device to maintain a copy of data received in a response message from said memory device.

6. The computing apparatus of claim 5 further adapted to employ an extension to an existing application programming interface for communicating with said memory device.

7. The computing apparatus of claim 6 further adapted to insert said instruction to said peripheral device into said command application protocol data unit.

8. A computer readable medium containing computer-executable instructions that, when performed by processor in a computing apparatus, said computing apparatus employing a system for authenticating access to said computing apparatus, said authenticating based on a data set comprising a plurality of biometric templates, cause said processor to:

transmit a command message to a peripheral device for forwarding to a memory device physically connected to said peripheral device, said command message requesting said data set, said command message including an instruction to said peripheral device to maintain a copy of data received in a response message from said memory device.

9. The computer readable medium of claim 8 further adapted to employ an extension to an existing application programming interface for communicating with said memory device.

10. The computer readable medium of claim 9 further adapted to insert said instruction to said peripheral device into said command application protocol data unit.

11. A method of facilitating, at a peripheral device, an efficient exchange of messages in a system for authenticating access to a base device, said authenticating based on a data set comprising a plurality of biometric templates, said method comprising:

receiving, from said base device, a command message for forwarding to a memory device physically connected to said peripheral device, said command message requesting said data set;

extracting an instruction from said command message;

forwarding said command message to said memory device;

receiving a response message from said memory device;

according to said instruction;

extracting a copy of data received in said response message; and

storing said copy of said data.

12. The method of claim 11 wherein said command message comprises a command application protocol data unit according to ISO 7816.

13. A peripheral device as part of a system for authenticating access to a base device, said authenticating based on a data set comprising a plurality of biometric templates, said peripheral device adapted to:

receive, from said base device, a command message for forwarding to a memory device physically connected to said peripheral device, said command message requesting said data set;

extract an instruction from said command message;

forward said command message to said memory device;

receive a response message from said memory device;

according to said instruction;

extract a copy of data received in said response message; and

store said copy of said data.

14. A computer readable medium containing computer-executable instructions that, when performed by processor in a peripheral device, said peripheral device being part of a system for authenticating access to a base device, said authenticating based on a data set comprising a plurality of biometric templates, cause said processor to:

receive, from said base device, a command message for forwarding to a memory device physically connected to said peripheral device, said command message requesting said data set;

extract an instruction from said command message;

forward said command message to said memory device;

receive a response message from said memory device;

according to said instruction;

extract a copy of data received in said response message; and

store said copy of said data.
