Facial database methods and systems
First Claim
1. A method comprising:
- (a) imaging a driver'"'"'s license using a handheld wireless device, thereby generating image data;
(b) identifying an excerpt of said image data corresponding to a facial photograph printed on the license;
(c) generating facial recognition parameters from said excerpt; and
(d) identifying possible matches in a database of facial data, by reference to said facial recognition parameters.

Abstract
Various arrangements for use of biometric data are detailed. For example, a police officer may capture image data from a driver license (e.g., by using a camera cell phone). Facial recognition vectors are derived from the captured image data corresponding to photo on the license, and compared against a watch list. In another arrangement, a watch list of facial image data is compiled from a number of government and private sources. This consolidated database is then made available as a resource against which facial information from various sources can be checked. In still another arrangement, entities that issue photo ID credentials check each newly-captured facial portrait against a consolidated watch list database, to identify persons of interest. In yet another arrangement, existing catalogs of facial images that are maintained by such entities are checked for possible matches between cataloged faces, and faces in the consolidated watch list database.

4. A method comprising:
-
collecting facial image data corresponding to sought-for persons, from a plurality of different agencies;
for each, computing faceprints using plural different algorithms, resulting in plural faceprints;
storing the plural computed faceprints for each sought-for person in a database;
receiving faceprint data corresponding to a person not known to be sought-for, said received faceprint data having been computed according to a first algorithm; and
checking a subset of said stored faceprints that were computed using said first algorithm, for correspondence with said received faceprint.

5. A method practiced by a law enforcement officer, comprising:
-
using a handheld wireless device, capturing image data corresponding to a person stopped by the officer;
processing the captured image data to enhance its utility as a reference from which a faceprint can be derived;
generating a faceprint from the processed image data; and
checking a collection of previously-stored faceprints for correspondence with said generated faceprint. - View Dependent Claims (6, 7, 8, 9, 10)

- 11. In a method of issuing state driver'"'"'s licenses that includes capturing facial portrait data from an applicant, and checking a collection of previously stored facial image data to determine whether a license has previously been issued to a person of similar appearance, an improvement that includes generating a faceprint data from the captured facial portrait data, and sending at least a portion of said faceprint data to another entity for screening against facial data of sought-for persons.
