Abstract

Apparatus for providing repetitive enrollment in a plurality of biometric recognition systems based on an initial enrollment is provided. The apparatus includes an extractor for extracting a biometric attribute from a user. Further, a server is included, operatively coupled to the extractor, for interfacing with the plurality of biometric recognition systems to receive requests for biometric attributes therefrom and transmit biometric attributes thereto. The server has a memory device for storing the biometric attribute.

Claims

(d) enrolling in each of the plurality of biometric recognition systems based upon the biometric attribute.

2. The method of claim 1, further comprising the step of encrypting the extracted biometric attribute before storing.

3. The method of claim 1, further comprising the steps of:

(a) extracting a non-biometric attribute from the user; and

(b) storing the non-biometric attribute in the memory device of the server for subsequent use by any of the plurality of biometric recognition systems.

4. The method of claim 1, wherein the extracted biometric attribute is a digitized fingerprint.

5. The method of claim 1, wherein the extracted biometric attribute is stored in a format corresponding to raw data to provide compatibility between the server and the plurality of biometric recognition systems.

7. The method of claim 5, further comprising the steps of:

(a) extracting a non-biometric attribute from the user;

(b) encrypting the extracted non-biometric attribute;

(c) storing the encrypted non-biometric attribute in the file; and

(d) storing the file in the memory device of the server for subsequent use by any of the plurality of biometric recognition systems.

8. The method of claim 7, wherein at least one of the plurality of biometric recognition systems is capable of recognizing biometric and non-biometric attributes, said method further comprises the steps of:

accessing the non-biometric attribute from the memory device of the server for enrollment in the at least one of the plurality of biometric recognition systems; and

enrolling in the at least one of the plurality of biometric recognition systems based upon the non-biometric attribute.

10. The method of claim 7, wherein the non-biometric attributes are selected from the group consisting of a password, a personal identification number (PIN), and personal information.

6. A method for providing repetitive enrollment in a plurality of biometric recognition systems based on an initial enrollment, comprising the steps of:
