`ABSTRACT
`[57)
`
`The present invention is a system and method of providing
`system integrity and positive audit capabilities to a positive
`identification system. The use of access authority infonna(cid:173)
`tion units to gain access to the positive identification system
`solves the problems of open, unsecured and unauditable
`access to data for use in point of use identification systems.
`In order to secure the rights to the data that is needed to make
`mass identification systems operate. it must be shown that
`records will be closed and secure, as well as that there will
`be an audit ttail of access that is made to the data. This
`system solves those problems through the use of a system
`and method for identification with biometric data and/or
`personal identification numbers and/or personaliz.ed devices
`embedded with codes unique to their assigned users.

`
`FIELD OF THE INVENTION
`The present invention relates to the field of identity
`verification. Specifically. the invention is directed to a
`system and method of providing system integrity and posi(cid:173)
`tive audit capabilities to a positive identification system.
`More particularly. the system and method uses personal
`identification numbers (PINs) to limit access to the identi(cid:173)
`fication related devices to personnel who are authorized to
`do so. The PINs can be implemented as a simple number that
`can be typed into an input keypad when access to the
`positive identification system is desired. A more robust
`implementation of the PIN system is implemented as a
`portable storage device or electronic key that holds a read(cid:173)
`able code which is associated with an authorized user of the
`positive identification system. Finally. either PIN
`implementation, or both. can be used in identification of the
`system user at the point of verification terminal.

`which depend on the fact that the person presenting the form
`of payment is actually the person having the legal right to
`use the underlying account. even a small percentage of
`fraudulent transactions results in billions of lost dollars. The
`5 cost of this fraud is paid for, indirectly. by the consumers in
`the form of higher credit card interest rates and fees and. in
`part, by the merchants accepting such credit cards in the
`form of higher transaction commissions.
`Methods used to combat fraud have been the use of
`10 holographic images on cards. the need for a validation
`requester to obtain transaction approval. the encoding of
`cardholder information on magnetic strips on the back of the
`card. as well as signature verification. A number of patents
`have issued on identification devices and methods. Of par-

`
`SUMMARY OF THE INVENTION
`The present invention is a system and method of posi(cid:173)
`tively identifying individuals. The system comprises a point
`of identification terminal having a means for inputting data
`presented by a particular individual, at least one database
`storage and retrieval site having stored therein a plurality of 60
`digital image data unique to persons to be identified, and a
`means for exchanging data between the point of identifica(cid:173)
`tion terminal and the database site. The database site com(cid:173)
`prises a means for validating that a point of identification
`terminal seeking to exchange data with the site is authorized 65
`to do so. The database site also comprises a means for
`validating that a system user is authorized to access the
`
`DETAilED DESCRIPI1ON OF THE
`INVENTION

`presented by a consumer, or presenter, in order to make a
`purchase. Thus, the system will make particular references
`to credit card account numbers, and the like. However. it is
`understood that the positive identity verification system
`disclosed herein is adaptable to any application where
`positive identification of a person is required. Such alterna(cid:173)
`tive applications comprise checking and banking
`transactions, firearm sales. food stamp reimbursement and a
`host of other applications related to the welfare. voting. law
`enforcement. health care. airline, immigration and natural(cid:173)
`ization fields.
`Referring now to the figures, a positive identification
`system in accordance with the disclosed invention is shown.
`A point of verification terminal 1 is located at a location
`where the identity of persons present is required to be
`verified. The point of verification terminal comprises a
`standard magnetic strip reader 4, an optional bar code reader
`4', a check scanner 4", all of which are well known in the art,
`an input keypad 5, a display means 6, which is preferably a
`miniature flat panel display. a controller 7, and an internal
`communication modem or other communications means 8.
`Although the rate of data exchange may vary depending on
`the availability of quality phone lines or other means of data
`transmission, such as a dedicated wide area network or a
`satellite communications link. the system would transmit
`data at a rate of at least 9,600 baud per second (bps).
`However, quality data transmission media will allow for
`data exchange at rates of 14,400 bps, 28,800 bps or even
`higher baud rates.
`In a credit card transactional situation, the point of veri(cid:173)
`fication would be the point of sale, which typically incor(cid:173)
`porates a cash register and prior art credit card verification
`systems. Upon presentation of a standard credit card 2, the
`store clerk or other individual responsible for positive iden(cid:173)
`tification would input the credit card account number into
`the point of identification terminal 1. The preferred method
`of inputting the credit card information would be by swiping
`the credit card through the standard magnetic strip reader 4,
`which would be capable of reading credit card account
`information, which is currently encoded on magnetic strips
`on the reverse side of virtually all credit cards. In the
`alternative, if the magnetic strip containing the account data
`is corrupted, which routinely occurs due to either wear or
`contact with a powerful magnetic field, the identifier would
`simply read the account number off of the credit card, where
`it is typically provided in embossed characters, and input the
`credit card account number into the point of identification
`terminal using keypad 5. Another alternate means of input(cid:173)
`ting the credit card account information into the point of
`verification terminal would be to utilize a coded medium
`such as a bar code. In this embodiment, the magnetic strip
`reader 4 would be replaced by a standard bar code reader to
`transfer its data to the code reader 4' and onto controller 7.
`Another embodiment of the invention would include check
`scanner 4", which would be used to scan checking account
`number information off of a standard personal or company
`check. which would expand the role of the system from
`credit/debit card transaction identity verification to checking
`related transactions as well.
`In addition to the credit card account information, the
`identifier could manually input any other information
`needed to aide in the identity verification process via keypad
`5. Such additional information could be whether the pre(cid:173)
`senter is male or female, in which case the keypad could
`incorporate a specific key to correspond to the male-female
`choice 5' or whether the presenter is a dependent of the credit
`card owner, in which case the keypad would incorporate a
`specific key 5" to correspond to dependent choice.

`Once the account number is entered into the point of
`identification terminal 3, the terminal would initiate com(cid:173)
`munications via its internal communication means, which
`could be a modem or wide area network (WAN) device to
`5 one of a number of remote database storage sites 9-11 using
`public phone lines 12. Alternative forms of communications
`links are envisioned as well, and include satellite
`communications, or dedicated network means. The actual
`site accessed would be a function of availability and loading
`10 on the public access phone lines. network availability.
`retrieval site availability or other system availability criteria
`at the time the terminal initiates communications with a
`remote database site. Communications will then be estab(cid:173)
`lished with an input/output controller 13 at the remote
`15 database storage site through a modem bank 14 at the
`database storage site, the controller 13 would initiate a query
`to the point of identification terminal 3 to verify that the
`terminal has the appropriate authority to access the remote
`database site and is a valid device. One simple and cost
`20 effective method of performing this query is to use com(cid:173)
`monly available caller ID technology to ensure that the
`request for data has been originated from an authorized
`telephone line. Additionally, a software key may be incor(cid:173)
`porated into each point of identification terminal which will
`25 respond in a predetermined manner when queried by a
`remote database storage site.
`Once controller 13 verifies that the requesting point of
`identification terminal 3 is a valid device and has the
`appropriate access privilege, the terminal will be allowed to
`30 transmit an information request to the database storage site.
`The information request is also received by input/output
`controller 14, over a high speed network 15. The high speed
`network may be fiber distributed data interface (FDDI),
`asynchronous transfer mode (XIM) or any other suitable
`35 cost effective high speed network The information request
`is then routed to one of a number of database servers 16-18
`where the credit card account data is processed. The selected
`server then accesses a set of high speed, high reliability disk
`arrays 19-23 and retrieves the digital photographic or other
`40 image or other unique personal data associated with the
`account data received by the database server.
`In addition to retrieving the digital image or other unique
`personal data stored at the remote database site. the database
`site would be configured to allow input/output conlroller 13
`45 to initiate additional information requests from outside
`information databases. One such scenario envisioned in the
`credit card processing example would be for the database
`site to query any one of a number of existing credit autho(cid:173)
`rization agencies (CAA) to verify that the credit card
`50 account being processed is valid and within its pre-approved
`credit limit. An alternate embodiment would be to have the
`remote database storage and retrieval site(s) co-located at a
`one or more CAA sites.
`The identifier, which would be the sales clerk in a retail
`55 establishment, would only need to input the credit card
`information into one device and would receive both credit
`approval and identity verification from a single source. In
`this scenario, input/output controller 13 would initiate a
`credit authorization request to an outside CAA 23 through
`60 modem bank 14 over public access telephone lines 12 or
`through a WAN connection 14' or the like. H the amount of
`the transaction is approved by the CAA 23. the database site
`would receive the credit approval code from the CAA and
`retransmit the code to the point of verification terminal along
`65 with the digital image information or other unique data over
`its established communications link The credit approval
`code would be displayed either on the display means 6 of the

`point of verification terminal or. in the alternative, on an
`optional second display means 6'.
`The point of identification terminal would then receive the
`information via modem or WAN connection 8 and route it to
`controller 7. which would process the information received
`and display the digital image received on either display
`means 6. In one embodiment of the invention. the digital
`information would be stored at the remote database storage
`site in a compressed state and be transmitted to the point of
`identification terminal in the compressed state so as to
`minimize the time associated with a particular transaction.
`In this embodiment. the controller 7 would first decompress
`the digital photographic information and then display the
`information on display means 6.
`Another embodiment of the invention. which would be
`used for situations where the highest security of information
`would be required. the digital image information would be
`encrypted in addition to being compressed while it is being
`transmitted to a point of verification terminal. In this
`embodiment, the tenninal controller 7 would be required to
`decrypt as well as decompress the photographic information
`in order to allow the information to be displayed on the
`display means.
`The store clerk. or other person responsible for identity 25
`verification would then visually compare the image dis(cid:173)
`played on the display means with the physical appearance or
`the signature of the person presenting the credit card at the
`point of verification. If a match exists, then the clerk would
`input a specified keystroke sequence on input keypad 5 to 30
`indicate that the clerk has in fact verified that an identity
`match exists.
`F1G. 5 shows the positive identification sequence using a
`memorized personal identification number (PIN) for each
`clerk tasked with verifying the identity of a person com- 35
`pleting a particular transaction. First, each clerk is assigned
`a unique PIN, which each clerk must memorize. The PIN
`serves as an access authority information unit, which will
`allow only authorized users to access the remote database
`site. Each memorized PIN would then be mapped by the 40
`positive identification system to a single clerk in the secure
`database located at the remote database site. When a clerk
`logs into the point of identification terminal in order to
`access the information maintained in the remote database,
`the clerk will enter his or her access authority information 4s
`unit, which in this case would be his or her memorized PIN
`into the point of identification terminal. The positive identity
`verification system will then compare the memorized PIN
`that is entered into the system to determine if a match exists
`with a PIN assigned to a valid database user. If a match 50
`exists, th
