A Name of Applicant: Actual Inventor: Address for Service: Invention title: F k. C' Teruhiko Tamori MADDERNS, 1st Floor, 64 Hindmarsh Square, Adelaide, South Australia, Australia INFORMATION RECORDER/ PROCESSOR AND EQUIPMENT/SYSTEM CONTROLLER BOTH PROVIDED WITH FINGERPRINT SENSOR The following statement is a full description of this invention, including the best method of performing it known to us.

I PatAU132 Information recording/processing devices and machine/system controlling devices equipped with fingerprint sensors Technical Filed The present invention deals with information recording/processing devices and machine/system controlling devices that are equipped with fingerprint sensors.

Background Art Certain systems and machines require highly restricted operation and management in which unauthorized use is to be prevented and secrecy of the information being handled is to be ensured. The identity of the persons who operate the system/machine (hereinafter referred to simply as users) becomes :15 an important factor. Traditionally, certain codes, passwords, ID numbers, etc., that are specific to the user, have been employed.

However, long code numbers are difficult to remember, whereas short ones are easily deciphered, and the passwords and ID numbers are always at risk of being found out by others. Even codes are not completely immune from being deciphered by others, and it is generally considered that a fool-proof and perfect method can not be found.

In recent years, however, "fingerprints", which every individual is born with and which have the characteristics of being unique to each individual and permanent, are drawing la greater attention as a means of identifying a person, a method which does not have the above-mentioned shortcomings. For example, Japanese Patent Unexamined Publication No. 6-274759 (274759/1994) and Japanese Patent Unexamined Publication No. 21400 (21400/1998) describe fingernrint matching systems that -I ,I t J L- I compare a fingerprint input by a user of the system or machine with pre-registered fingerprints of authorized users, and allow the user to operate the device if there is a match that confirms the identity of the user. This type of fingerprint-based user 1 identification system is sufficiently effective for many applications.

oy.. The detecting or reading of the fingerprint is however done optically in conventional fingerprint matching systems, light is shone on the fingerprint and the reflected light is .5 received by photoelectric elements such as CCDs and converted into electrical signals. These systems are readily affected by the presence of sweat, dirt, moisture, etc. and also by external light in the case of outdoor applications, besides having other o• problems like limitations in the environment and mode of application and difficulty in miniaturization because of the requirement of a light source, mirror, prism, etc.

Presently, there is a trend for many systems and devices to provide increased performance with a greater number of functions, and for the user to be one or several individuals including the 2 55 owner, depending on the application. This has made it desirable to select or limit the functions or to change the particulars of processing or management depending for instance on the age of the authorised user or the status of other users. To do this with convention systems and machines, the user or persons other than the user have to set or change the desired conditions depending on the requirement either before operating the system or during its operation, which is quite cumbersome. If the data about the use of the system or machine by each user is available, this is often very convenient for management, but with conventional systems, separate operation or processing is required for this.

Best Mode of Carrying Out the Invention i* We shall now explain the present invention with reference to 0. h the drawings.

Figure 1 shows the external appearance of a driver's license that is an example of an information recording/processing device which is a first embodiment of the present invention, and Figure 1 shows the external appearance of a portable read/write device that reads the information stored on the license or writes new information to it.

The driver's license 1, which is the information recording unit, has an IC memory embedded in the case 11 preferably made of plastic, a part of its surface has an exposed terminal 12 for connecting with an external terminal, and it has a fingerprint 6 69. 00:00 0 0 60 000 .00 0: 0 0 o 0 0 0 0 0 0 0 0 0000 000 00 000 0 0 0 sensing module 13 through which the fingerprint of the owner is input.

The portable read/write device 2, which is the information processing unit, is in the possession of a person (like a police officer) with the authority to inspect or modify the information in the license, and the front upper surface of the plastic case 21 has a slot 22 into which the license 1 is inserted. The central upper part of this casing has a liquid crystal display unit 23 that displays the information stored in the license or S.O0 information that will be written on it, the rear part of the casing has the keys 24 used for inspection, reading, or writing

*S

of information on the license, and the rear end of the casing has T: a fingerprint sensor module 25 for inputting fingerprints. The 0 S% fingerprint sensor modules 13 and 25 have thin surface pressure input panels, for instance, of the type described in Japanese Patent No. 2,557,795, the disclosure of which is incorporated by reference. This surface pressure input panel may preferably be I* an active matrix type display system in which thin film transistors (TFTs) drive the liquid crystals. The panel has a configuration of the type shown in Figure 2, with a pressure sheet 100, preferably formed by vapor deposition of a conductive film lOOa on the back side of an insulator film made of a material like PET (polyethylene terephthalate), placed over a circuit board 200. The circuit board 200 preferably has an 7 amorphous silicon film formed on an insulator base plate 200a preferably made of glass, ceramic, etc., a number of TFTs thin film transistors) 200b, drain wires 200c and gate wires 200d formed by a well-known photo-lithographic technique, and conductive contact plates 200e, made of ITO (indium tin oxide) for instance, formed by vapor deposition. The drain wires 200c and gate wires 200d are arranged in a matrix pattern and function as scanning electrode wires when a scanning signal is applied, as will be explained later. Because the suitable gap for the drain 10 wires 200c and gate wires 200d is 20-100 microns for fingerprint detection, a number of unit detection elements with the drain and gate of each TFT connected to the drain wire 200c and gate wire 200d respectively and the source connected to the conductive contact plate 200e are preferably formed on the circuit board 200.

The drain wires 200c and the gate wires 200d are respectively gathered at sites A and B of the insulation base plate 200a which are connected to an external circuit connector not shown in the Figure, as would be known by those of ordinary skill in the art.

5 55 A panel with 15 x 15 mm area for pressing the finger tip and thickness 1 mm has been prepared and used as the fingerprint sensor module with the structure described above. When a finger is placed on this surface pressure sensor panel and the panel pressed lightly, the electrically conductive contact plate 200e of the unit detector element located exactly below or almost 8 5 5 a 5 S S S S S s .ji~ below a ridge of the fingerprint becomes electrically connected with the conductive film 100a on the backside of the pressure sheet 100. However, the electrically conductive contact plate 200e of a unit detector element exactly below or near a valley of te fingerriLnt does not become ectrically connected wi t the conductive film 100a. So, when an x-direction resistor is connected to the drain wires 200c and a y-direction resistor is connected to the gate wires 200d and scanning signals are applied sequentially from each resistor at certain separate timings, the ridges and the valleys at the position of each unit detection Og** element can be detected and thus the fingerprint pattern as a whole can be sensed.

Figure 3 is a block diagram of the license 1 and the portable read/write device 2 showing the functional configuration.

The license 1 has a memory A where the fingerprint data of the owner may be preferably stored and a memory B in which the address, name, sex, and date of birth of the owner, the category of license, history of accidents (nature of the accidents and places and dates of occurrence) and the current points score, etc.

that are specific to the owner of the license may be preferably maintained. Memories A and B are preferably IC memories. The specific information about the owner of the license is preferably stored in the memory B before issuing the license 1.

9 0550 0500 5o 05 5 5 0 Apart from the earlier mentioned display unit 23, keys 24, and fingerprint sensor module 25, the portable read/write device 2 has a memory C 26, which stores the fingerprint data of a person (a police officer, for instance) who has authority to inspect or rewrite the information in the license, a matching unit 27 where the offered fingerprint data and the pre-registered fingerprint data are compared, and a buffer 28 where the data taken out from the license 1 is temporarily stored. We shall now explain how the above-described license system is used.

Police officers who are likely to use the portable read/write device 2 in the course of performing their duty .iji: register their fingerprint data and keep it the memory C. Now, g:o if a traffic accident occurs, the police officer who deals with the accident turns on the power source (not shown in the Figure) of the portable read/write device 2 and inputs his fingerprint data by pressing his finger on the fingerprint sensor module The fingerprint matching unit 27 then compares the offered fingerprint with the fingerprint data in the memory C, and if there is a match, it confirms that the officer is indeed an authorized person, and assumes the standby condition, permitting the display unit 23 and the keys 24, etc., to operate.

With the portable read/write device in this condition, the officer demands to see the driver's license, inserts it into the slot 22 of the read/write device 2 as indicated by the broken line in Figure 2, and directs the driver to place his or her finger on the fingerprint sensor 13 of the license 1. In this manner, the fingerprint data of the driver is taken into the buffer 28 of the read/write device 2. The portable read/write device 2 reads out the fingerprint data of the driver from the memory A and specific information about the driver from memory B via the connecting terminal 12 of the license 1, temporarily stores the data in these buffer 28, and compares the fingerprint data offered through the fingerprint sensor 13 and that which reads out from memory A in the matching unit 27, and verifies the identity of the owner and displays the specific information about the owner in the liquid crystal display unit 23 if there is a match.

The police officer inputs particulars about the accident by 5 using the keys 24 and updates the points score, etc. This new information is displayed on the display unit 23 and stored in the memory B of the license 1.

In the example described above, a liquid crystal driving panel was used as the fingerprint sensor module. However, a piezoelectric sensor panel in which the frequency of the piezoelectric film changes depending on the fingerprint pattern (Japanese Patent No. 2,557,796), a magnetic sensor panel in which the magnetic resistance changes (Japanese Patent No. 2,520,848), a system in which the contact resistance changes (Japanese Patent No. 2,069,288), a system in which the resistance changes by distortion, and other such thin surface pressure input sensor panels can be used. The method described in Japanese Patent No.

2,030,279, which employs the microprocessing technology generally used for producing semiconductor devices, can be employed for preparing the fingerprint sensor module.

In the above example, the fingerprint matching unit and the display unit are provided in the portable read/write device. But these may be provided in the license itself so that the personal information about owner of the license can be displayed on the display unit at the time of matching of the fingerprints. In that case, the power source and other necessary circuits need to be built into the license.

In the description given above we have used a license as an example of a portable card. However, the present invention can be applied with similar effect to other cards and booklets, such as a citizenship card issued by a country or a local government, pension booklets, health insurance certificates, passports, library cards, credit cards, etc.

Figure 4 is a conceptual diagram of a car driving system that is machine/system control device of the second mode of application of the present invention.

The car driving system consists of a remote controller 3, a photocell 4a for receiving infrared light installed on the 12 outside of the driver's side door of the car, data input keys 4b installed on the dashboard inside the car, and a control circuit 4c attached below the console. The photocell 4a which is meant for receiving data from the remote controller 3, the data input keys 4b, and the control circuit 4c constitute the vehicle velocity control circuit.

Figure 5 is a block diagram showing the configuration of the circuits of the car driving system. The remote controller 3 has a fingerprint sensor module 31 that detects fingerprint data when j0 a finger is placed over it, a fingerprint data processing unit 32 that extracts the characteristic point called minutiae of the p fingerprint from the detected fingerprint data, and a transmission unit 33 that sends out the minutiae data in the form of an infrared beam, and also a built-in battery for the power a supply.

Apart from the liquid crystal driving type panel shown in SFigure 2, piezoelectric, magnetic, contact resistance type or the like thin surface pressure input sensor panels can be used as the fingerprint sensor module 31, as explained earlier for the first mode of application of the invention. Because of these features, a remote controller that is significantly smaller, thinner and lighter weight than conventional optical type fingerprint sensors can be created.

13 On the other hand, the receiver unit 4 on the main body of the car receives, through the photocell 4a, the infrared beam transmitted by the remote controller 3 and outputs it as an electrical signal to the control circuit 4c. The control circuit 4c has as its components, a fingerprint registering memory 41 which is non-volatile memory like an E2PROM that remembers the minutiae data of the fingerprint of the driver (or drivers), a fingerprint matching unit 42 that compares an offered fingerprint with the fingerprints stored in the fingerprint register memory 41, a personal information memory 43 that remembers information specific to the driver (name, sex, age, license number, category of the license, upper speed limit, etc.), a vehicle speed controller 44 that monitors the engine RPM, the extent to which the accelerator has been pressed and the vehicle speed, and outputs the acceleration signal, and an acceleration deciding unit 45 which decides whether to permit acceleration or not, on the basis of driver-specific personal information. The personal information of each driver and the minutiae data of his or her

C

fingerprint are registered beforehand through the data input keys 4b.

We shall now explain the functioning of the car driving system having the structure described above.

Figure 6 shows a flow chart illustrating the functioning of the car driving of this system. Figure 6(a) is the flow chart of 14 CCCC... *CCC* CC C C the door unlocking action and 6(b) is the flow chart of the vehicle speed control function.

At the start of driving, the driver places his or her finger on the fingerprint sensor module 31 while aiming the remote controller 3 at the receiver photocell 4a on the driver's side door of the car When the finger is placed on the sensor module, power supply to the remote controller 3 starts automatically, and the transmission unit 33 of the remote controller 3 transmits the minutiae data of the fingerprint in the form of an infrared beam (S-2) When the receiver photocell 4a on the door of the car, the power source of which is always on, receives the infrared beam, power is supplied to the fingerprint register memory 41 and the fingerprint matching unit 42 and at the same time the minutiae point data is converted into an electrical signal and transmitted to the fingerprint matching unit 42 of the control circuit 4c.

The fingerprint matching unit 42 reads out the minutiae data of the fingerprints of registered drivers kept in the fingerprint register memory 41 and compares them with the minutiae data of the fingerprint received from the remote controller 3 If there is a match, the system assumes that the driver has been authenticated and outputs the door unlocking signal to the door unlocking mechanism 6, and then the door on the driver's side is unlocked C go o• o o The system is made so that when the door is unlocked, power is supplied to the whole of the control circuit 4c and the personal information stored in the memory 43 about the driver who has been authenticated by the fingerprint matching is read into the acceleration deciding unit 45 When the engine is started after this, power is supplied to the vehicle speed controller 44 of the control circuit 4c and the vehicle starts running through the standard procedures for driving. While the car is running, the engine rpm, car speed, and the extent to which the accelerator has been applied are detected and fed into the vehicle speed controller 44 and the vehicle speed controller 44 outputs an acceleration signal 0 calculated from this information using a pre-determined formula or table.

The acceleration deciding unit 45 outputs a vehicle speed limiting signal when the vehicle speed signal output from the speed controller 44 exceeds the driving speed limit fixed for that driver (for example, the upper limit may be fixed at 70 kph for a driver A who is 60 years or older) (F-3 and This speed limiting signal is led to an electronic fuel injection control device and the vehicle velocity is maintained below the limit (at not more than 70 kph) by cutting down the amount of fuel injected into the engine If the speed of the car is less than 70 kph, it is increased by ordinary throttling 16 controller Thus, in this mode of applying the present invention, after fingerprint verification, not only is the door unlocked, but the speed of the car is automatically controlled below a certain pre-fixed level on the basis of the personal informat-on about the user to whom the fingerprint belongs.

Therefore, the system is free from the cumbersome process of having to reset the upper driving speed limit every time.

In the above-described Mode 2 of applying the present invention, the fingerprint register memory 41 which is used for storing the fingerprints of the drivers, and the fingerprint tr, matching unit 42 are located in the control circuit 4c in the car.

SBut alternatively they can be located in the remote controller 3 and matching can be done in the remote controller.

Apart from the above-described example, the following applications are possible examples of limiting or controlling the operation of machines or systems after the verification of the person through a fingerprint.

Applications in which access is limited or the functions are limited or controlled: Personal computers, Internet communication devices, multimedia terminals, digital broadcast receiver-decoders, digital recorders, videotape recorders, digital cameras, copiers, game machines, portable terminals, domestic telephones, and electronic clinical charts.

17 *a a.o• a• a oo Applications in which data are gathered or memorized, and dealt with differently depending on the identity of the individual: telephones, game machines, cash dispensers, ATMs, automatic coin operated dispensers, home banking systems, pinball game card terminals, money-related electronic equipment (electronic cash dispensers, electronic balance display machines, electronic wallets, and electronic safes), and POS terminals.

In the newly invented electronic information .10 recording/processing devices and machine and system control JI** devices equipped with non-optical thin surface pressure input type fingerprint sensors, the user is verified by fingerprint matching. As such, they have a number of advantages, including improved security such as prevention of unauthorized use or y5 impersonation by persons who resort to theft or fraud, the elimination of the risk of counterfeit passwords, the need to remember a code or ID, or the risk of being decoded by computers, etc., unlike conventional devices which use code numbers, o* passwords, or IDs. Apart from this, the newly invented devices have the advantages mentioned below.

In the newly invented information recording/processing devices equipped with thin surface pressure input type fingerprint sensors, the fingerprint sensor itself is very thin, lightweight and compact. As such, it is convenient as 18 oo o• oo e o 0 a portable device. If they can be incorporated into IC's they can be used in citizen's or social security cards issued by a national or local government, pensioner's booklets, health insurance card, passports, library cards, credit cards, and other similar cards and records. Even if such a card is lost, there is no risk of its being used by an unauthorized person.

Although these are not as thin as IC cards, because they are small in size, lightweight and compact, they can be used in remote controllers or terminals of various electronic devices and consumer apparatuses.

.If a display unit is provided in the above-described card, booklet, or terminal, the data stored inside can be used freely at any time, by the user or by authorized It persons, off line.

In the newly invented information machine/system control device equipped with a thin surface pressure input type fingerprint sensor, the fingerprint sensor itself is extremely thin, light and compact. As such, the sensor can be implemented without modifying the design or structure of the device. Another major advantage is that access to the machine or system operated by a user can be limited, the functions and operations of the system can be limited or controlled, and collection and management of the data about 19 oo oo o .oo ooo oo o the use of the system can be automatically accumulated, all in relation to the individual information such as sex, age, the organization to which the person specified by the fingerprint belongs, etc. Therefore, there is no need to separately set the conditions of use or to tally the data every time.

The fingerprint sensor used in Mode 2 of applying the present invention need not be a thin surface pressure input type fingerprint sensor in certain applications (game machines placed at game centers and cash dispensers in banks, for example) as long as it serves the purposes of user identification and data collection and storage.

INDUSTRIAL APPLICABILITY The present invention can also be effectively used in a portable small lightweight unit such as a card, terminal, etc. in devices that require user verification. After verifying the user, the operation or functions of the apparatus can be limited or controlled.

It will be understood that the term "comprise" and any of its derivatives (eg.

comprises, comprising) as used in this specification is to be taken to be inclusive of features to which it refers, and is not meant to exclude the presence of any :20 additional features unless otherwise stated or implied.
