## Background
This application claims priority under 35 U.S.C. §119 to U.S. Provisional Application No. 60/604,054, titled “Biometric Identification System, Method and Medium for Point of Sale Environment,” filed Aug. 25, 2004, and assigned to HSBC North America Holdings, Inc, which is incorporated herein by reference in its entirety.


FIELD OF THE INVENTION
This invention generally relates to a biometric identification system, and particularly to a biometric identification system, method and product for facilitating a transaction in a point of sale environment.
BACKGROUND OF THE INVENTION
Most transactions at a retailer's POS (Point of Sale) system require the presence of a physical token to gain access or authorization. Tokens such as magnetic ink encoded paper checks, smart cards, magnetic swipe cards, identification cards or even a personal computer programmed with resident user-specific account data, are “personalized” because they are each programmed or encoded with data that is unique and personalized to the authorized user. The customer then enters the account number from the physical token through a magnetic stripe reader, through a contactless transmission (Radio Frequency or Infrared), or through the manual entry via a numeric keyboard. Whether a consumer is buying groceries with a debit card, shopping in a department store with a credit card or earning free frequent flyer miles over the internet, at the heart of that transaction is an electronic transfer of funds or benefits enabled by the token, which acts to identify both the consumer as well as the financial account being accessed.
Also, there are transactions where the physical token is not required and the retailer allows payment by utilizing identifiers such account numbers, passwords, and/or personal identification numbers (PINs) to identify authorized users and control access to specific locations. Unfortunately, such methods for authorizing transactions or for controlling access can be easily compromised. Account numbers, passwords, PINs, etc. can be discovered by non-authorized persons or can be willingly disclosed by authorized users to non-authorized persons.
The growing field of biometrics provides one technological answer to this need for more reliable identification. Biometric technologies measure and characterize some unique feature of a person's anatomy, which is then used to identify that person.
A number of biometric identification devices already exist. These include fingerprint readers, hand geometry readers, iris imagers, retinal cameras, voice recognition, and face recognition devices. The biometric identification devices are used to verify that a person presented is indeed that person by comparing the presented person's biometric data to biometric data stored for the person specified. Authentication can be done for any purpose, such as security, tracking, crime prevention, customization of other systems to user preferences, communication and other purposes. Each of these biometric identification devices has its own problems and strong points.
Various token-based biometric technologies also exist. These suggest using smart cards, magnetic swipe cards, or paper checks in conjunction with fingerprints, hand prints, voice prints, retinal images, facial scans or handwriting samples. Biometrics are generally either stored in electronic and reproducible form on the token itself, or used in tandem with the user directly using magnetic swipe cards, paper checks or a PC. Therefore, a significant risk of fraud still exists because the comparison and verification process is not isolated from the hardware and software directly used by the payer attempting access.
There is a need to decrease the time required for transaction, to simplify the process where the customer is no longer required to present a physical token to identify themselves, and to simultaneously minimize the risk of fraud. It would be desirable to have an identification system that recognizes a customer based upon an “identifier” and a biometric sample for the purpose of authorizing a purchase or making changes to a record including the protection of a customer's account. Accordingly, the present invention is directed to these, as well as other, important ends.

DETAILED DESCRIPTION
Embodiments of the present invention provide a biometric identification system, method and product for facilitating a transaction in a point of sale environment. Referring now to the drawings, and more particularly, to FIG. 1, there is shown a biometric identification system, generally designated 100, for facilitating a transaction in a point of sale environment that incorporates various embodiments of the present invention. System 100 includes at least one host system 102 (e.g., IBM Mainframe Computer, IBM Corporation, White Plains, N.Y.), at least one biometric database 104 (e.g., UDB database, IBM Corporation, White Plains, N.Y.), at least one host network 106, at least one cable network 108 (e.g., Comcast Corporation, Philadelphia, Pa.), at least one telephone network 110 (e.g., Digital Subscriber Line, Verizon, New York, N.Y.), at least one merchant internal network 122, and at least one merchant data input device 124, each as described in reference to FIG. 1.
In one example of the present invention, the merchant data input device 124 receives data from a customer to authorize a transaction. In one example of the present invention, the merchant data input device 124 may include at least one point of sale system 126, at least one Personal Digital Assistant (PDA) 128 (e.g., I-PAQ, Hewlett-Packard Company, Palo Alto, Calif.), at least one service desk 130, and at least one biometric recognition device 132 (e.g., ePad-id, Interlink Electronics Inc., Camarillo, Calif.). The merchant data input device 124 transmits the data via the merchant internal network 122 to a host system 102. The host system 102 receives the data via a host network 106 and utilizes this data to retrieve a biometric template previously stored in the biometric database 104. The host system 122 then validates this data against the previously stored biometric template to determine if the customer is authorized to proceed with the transaction. The host system 122 transmits the results of the validation back to the merchant data input device 124.
One or more embodiments of the present invention relate to an identification system that recognizes a customer belonging to a predefined customer group based on an identifier and validation of the customer's biometric sample. In one embodiment of the present invention, the predefined customer group includes customers having access to a single credit account opened by the predefined customer group, at a merchant, to purchase goods or services, wherein the line of credit can only be used at the merchant its subsidiaries, its partnerships, or through other relationships. Exemplary predefined customer groups include family members of a household, members of an organization, members of a club, and the like. The predefined customer group is assigned an identifier, and the customers belonging to the predefined customer group utilizes this identifier to validate themselves as belonging to the predefined group. In one embodiment of the present invention, identifiers for the predefined customer group include home phone number. One advantage contemplated by the use of predefined customer groups is to decrease time required to complete a transaction at a point of sale terminal by assigning customers to predefined customer groups and providing unique search parameters for targeted and reliable searches. Another advantage contemplated by the use of predefined customer groups is to simplify the process where the customer is no longer required to present a physical token to identify themselves and the verification is performed without accessing the financial account of the customer. In yet another advantage, the use of predefined customer groups with a biometric sample assists in recognizing a customer for the purpose of authorizing a purchase or making changes to a record and to simultaneously minimize the risk of fraud.
In another example of the present invention, the merchant data input device 124 receives data from a customer to enroll the customer's biometric data into a biometric database 104.
