Abstract

A device for use by an authorized person having an unique biometric parameter to obtain information for use in accessing a secured site. The device comprises a biometric interface unit engaged with a portable body member. The device further comprises biometric circuitry adapted to generate and store an initialized biometric template upon presentment of the person'"'"'s unique biometric parameter to the biometric interface unit. The biometric circuitry is further adapted to generate a second biometric template upon subsequent presentment of the person'"'"'s unique biometric parameter to the biometric interface unit. The device further comprises compare circuitry adapted to generate an first signal indicative that the second biometric template is substantially identical to the initialized biometric template. The device further comprises a storage device for storing a plurality of passwords. The device further comprises password circuitry adapted to generate a password in response to the first signal from the compare circuitry. The password circuitry being adapted to store the password in the storage device. The device further comprises water marking circuitry adapted to generate and embed a watermark within the password. The water marking circuitry may further comprise a plurality of memory registers and a data base having a plurality of public domain watermarks randomly assigned to each memory register. The device further comprises pager circuitry adapted to receive a signal from the secure site indicative that access has been attempted using said password and to generate an audible tone.

Claims

1. A device for use by an authorized person having an unique biometric parameter to obtain information for use in accessing a secured site, the device comprising:

(a) a portable body member;

(b) a biometric interface unit engaged with said portable body member;

(c) biometric circuitry adapted to generate and store an initialized biometric template upon presentment of the person'"'"'s unique biometric parameter to said biometric interface unit;

said biometric circuitry being further adapted to generate a second biometric template upon subsequent presentment of the person'"'"'s unique biometric parameter to said biometric interface unit;

(d) compare circuitry adapted to generate an first signal indicative that said second biometric template is substantially identical to said initialized biometric template;

(e) a storage device;

(f) password circuitry adapted to generate a password in response to said first signal from said compare circuitry, said password circuitry being adapted to store said password in said storage device; and

(g) pager circuitry adapted to receive a signal from the secure site indicative that access has been attempted using said password and to generate an audible tone in response to said signal from said secure site.

2. The device of claim 1, wherein said password is randomly generated.

3. The device of claim 2, further comprising an input device engaged with said portable body member, said password circuitry being adapted to allow the person access to said password using said input device.

4. The device of claim 3, wherein said input device is a key entry pad.

5. The device of claim 3, further comprising a display device and output circuitry adapted to allow the person to export said password to said display device so the person can view the password.

6. The device of claim 5, further comprising an output communication port connected to said output circuitry and adapted to allow the person to export the password to the secured site using through said output communications port.

7. The device of claim 6, wherein said password circuitry is further adapted to allow the person to change said password.

8. The device of claim 7, wherein said password circuitry is further adapted to allow the person to add a new password.

9. The device of claim 8, wherein said password has a length of at least eight characters thereby making it difficult for the person to remember said password after said a password is removed from said display device.

10. The device of claim 9, wherein said initialized biometric template is a fingerprint.

11. The device of claim 10, wherein said presented biometric parameter is a fingerprint.

12. The device of claim 1, wherein said biometric interface unit comprises a biometric input pad.

13. The device of claim 1, wherein said pager circuitry comprises a pager chip.
