Description

  The present invention relates to a fingerprint identification information terminal technology using fingerprints, and more specifically, performs fingerprint recognition and personal authentication using a biological feature called fingerprint that does not change over time. Makes it easy to place a phone number by touching a finger using the fingerprint assigned to one finger, and to input characters (including numbers), symbols, directions, etc., and to prevent unauthorized use The present invention relates to a fingerprint identification information terminal, a fingerprint identification input method, and a computer-readable recording medium in which the fingerprint identification input method is recorded as a program code.

  Generally, in order to prevent unauthorized use by a person other than the telephone owner, a technique for authenticating the person is required. Alternatively, telephone terminals that are used by multiple people, such as public telephones, can now be charged for each user by authenticating the user, and can be called without using a telephone card or cash. It is very convenient because it can be applied.

  Conventionally, it has been common to use a combination of a user name and a password for identifying a user as means for authenticating a user. However, relying on user names and passwords for identity authentication is a security risk. For example, when a password is stolen, there is a risk that another person may use the device. Also, if you forget your password, you cannot use the device, which is inconvenient.

  It is possible to record and save passwords in memos, etc., but in the recent advanced information processing society, the number of systems that require passwords is increasing, and these passwords are recorded and saved one by one. This has the problem that the burden on the user increases. Therefore, development of a technique for performing authentication without using a password is desired.

  In order to meet these demands, a technique for authenticating a person using biological features has been proposed. One of them is fingerprint authentication. In Japanese Patent Laid-Open No. 11-262059, the user's fingerprint data is input and collated with pre-stored fingerprint data. If there is a mismatch, the call cannot be made. A method of preventing unauthorized use of a terminal such as a mobile phone by performing processing is disclosed.

Japanese Patent Laid-Open No. 11-262059 JP-A-5-103068

  In the method disclosed in Japanese Patent Application Laid-Open No. 11-262059 (refer to Patent Document 1), the user's fingerprint data is input and collated with pre-stored fingerprint data. The telephone terminal can be used by permitting the entry of the telephone number and performing the outgoing call processing only in the case, but it is necessary to bother to enter the telephone number.

  Further, according to the method disclosed in Japanese Patent Laid-Open No. 5-103068 (see Patent Document 2), data such as a telephone number registered for each individual can be read and automatically dialed. However, according to this method, after fingerprint authentication, select and press the button with the desired phone number registered among the multiple one-touch dial buttons, or press the one-touch dial button after fingerprint authentication to register the registered phone number. It is necessary to select a desired number from among the numbers, and dialing is not easy.

In recent years, downsizing of information terminals has been rapidly progressing. However, the smaller the device, the easier it is to carry and the user-specific usage will be required, so a personal authentication technique is required to prevent unauthorized use. Various personal authentication methods have been proposed as described in the section of the prior art above, but personal authentication is used to determine whether to permit or not use, and after performing personal authentication, The operation is complicated because it is necessary to start the operation of the device.
There is also a security problem that once authenticated, no one can use it afterwards.

  In addition, characters, numbers, symbols, and the like are usually input using a keyboard in a normal computer and a 10-key bonder in a normal mobile phone. If these information terminals are further miniaturized, the input devices such as these keys and buttons must be miniaturized. However, there is a limit to reducing the size of the input device such as a button due to the restriction of the size of the finger.

(the purpose)
SUMMARY OF THE INVENTION An object of the present invention is to provide a fingerprint identification information terminal and fingerprint identification input method capable of inputting characters (including numbers) and symbols and moving control input of a mouse pointer and saving space, and a program code for the fingerprint identification input method. It is an object of the present invention to provide a computer-readable recording medium recorded as a computer.

  The fingerprint identification information terminal of the present invention records the fingerprint data captured by the fingerprint detection unit in the fingerprint data recording unit and collates it with the user's fingerprint data to determine whether it is the registrant's finger or who By authenticating and authenticating the finger and preventing unauthorized use by fingerprint authentication, it is possible to combine characters (including numbers) and symbols by combining features such as the owner, type, order, and direction of the finger placed on the fingerprint reader. An operation is performed by inputting or inputting the moving direction and moving speed of the mouse pointer. The user has little awareness of authentication and is easy to operate. Moreover, since authentication can be performed one by one, it is advantageous in terms of security. In addition, the number of buttons can be reduced.

  Furthermore, the present invention is characterized in that the fingerprint data recorded in the fingerprint data recording means is fingerprint data classified according to the characteristics of the fingerprint data so that it can be processed at a high speed during recognition.

  In the present invention, the above technique is applied to voice calls (telephones) or communications other than voice calls (such as facsimile machines), mobile communications (such as mobile phones), public telephones, and other information terminals in general.

  Furthermore, the recording medium of the present invention is a computer-readable recording medium such as a CD-ROM, DVD, or FD recorded as the above processing program codes.

  According to the present invention, illegal authentication is prevented by fingerprint authentication, and at the same time, a finger placed on the fingerprint reading unit or a character (including a number) or a symbol corresponding to the direction is input, the moving direction of the mouse pointer, A moving speed can be input, and a space-saving fingerprint identification information terminal can be realized.

Hereinafter, a telephone with a fingerprint telephone book will be described as an example of the fingerprint identification information terminal of the present invention.
FIG. 1 is a functional block configuration diagram of a telephone directory phone which is an embodiment of a fingerprint identification information terminal according to the present invention.

  In FIG. 1, 100 is a block of a telephone with a fingerprint phone book according to the present invention, 101 is a control unit for controlling the entire telephone 100 with a fingerprint phone book, 102 is a user name, which finger, which name of a hand, Key operation unit for inputting a telephone number or parameter of the other party, 103 is a fingerprint reading unit for reading and inputting fingerprint data, 104 is a fingerprint feature extracting unit for extracting features of the read fingerprint data, and 105 is read A fingerprint data recording unit 106 for recording fingerprint data and features is a display unit that displays an error when authentication is not possible, and displays the name and telephone number of the other party when authentication is successful.

  Reference numeral 107 denotes a parameter recording unit that records parameters used during authentication (parameters used depending on the authentication method are different but will be described below using “authentication standard similarity” as an example of authentication parameters); Is a fingerprint data comparison unit that compares the read fingerprint data with the fingerprint data in the database, 109 is a pointer that is assigned to the fingerprint data and a telephone number recording unit that records the telephone number and the name of the other party, 110 A telephone unit 111 is a power supply unit that supplies a power supply voltage to the entire telephone 100 with a fingerprint phonebook, and 112 is a classification unit that classifies fingerprint data according to features.

Hereinafter, a telephone with a fingerprint telephone directory according to the present invention will be described in detail with reference to the drawings.
First, a method for making a call using a registered telephone number (first embodiment) and a method for making a call by inputting a number (second embodiment) will be described.

(First embodiment)
In order to make a call using a registered telephone number, it is necessary to record fingerprint data, a telephone number, etc. in advance before use.
First, a method for registering fingerprint data, a telephone number, etc. will be described.

FIG. 2 is a flowchart of the registration operation to the telephone with a fingerprint phone book.
First, in step S <b> 10, a user name to be registered is input from the key operation unit 102.
Subsequently, in step S <b> 20, information related to the finger such as a finger type (for example, the index finger of the right hand) such as how many fingers is input from the key operation unit 102.

  Next, in step S30, the fingerprint reading unit 103 is placed with a finger to read and input the fingerprint data. In step S40, it is determined whether or not the fingerprint data is normally input. If the fingerprint data is not normally input (step S40: N), the process returns to step S30 again to input the fingerprint data. When it is normally input (step S40: Y), the fingerprint feature extraction unit 104 extracts various features from the input fingerprint data.

  For example, the classification unit 112 categorizes the categories according to features that can be processed at a relatively high speed during recognition, such as fingerprint types and features of some fingerprints. These extracted features and categories are registered in the database in the fingerprint data recording unit 105 together with the user name, finger type, and fingerprint data. For example, as disclosed in the above-mentioned Japanese Patent Application Laid-Open No. 11-262059, the user's fingerprint data is read by a fingerprint identification sensor, the shape is converted into a dot pattern, converted into data, and fixed storage. This can be realized by a method of storing in a general memory.

  In step S 50, the telephone number of the other party corresponding to the input fingerprint data is input from the key operation unit 102. In step S <b> 60, the name of the other party corresponding to the input fingerprint data is input from the key operation unit 102. If various data such as an address can be registered in addition to the name, the data can be easily called other than when making a call, so that the data can be used as an address book, which is convenient because the scope of use of the present invention is expanded. Data such as the telephone number and name of the other party corresponding to the input fingerprint data is recorded in the telephone number recording unit 109.

  In step S70, the registered content is displayed on the display unit 106, it is confirmed whether there is a mistake, and when "OK" is input from the key operation unit 102, the registration operation is completed. A reference value (such as authentication reference similarity) for personal authentication is separately input from the key operation unit 102 and recorded in the parameter recording unit 107. Note that the order of step S10, step S20, step S30 and step S40, step S50, and step S60 in FIG. 2 is an example, and the order may be interchanged.

Next, a procedure for using the telephone with a fingerprint phone book according to the present invention will be described.
FIG. 3 is a flowchart for explaining a procedure for using the telephone with a fingerprint phone book.

  In the figure, when an arbitrary finger is placed on the fingerprint reading unit 103 in step S100, fingerprint data of the placed finger is captured. In step S200, fingerprint recognition is performed on the captured fingerprint data, and then the similarity between the captured fingerprint data and the most similar fingerprint data is calculated. The higher the similarity, the more similar the two fingerprint data. The most similar fingerprint data is selected from the fingerprint data recording unit 105.

  The calculated similarity is compared with the reference value for authentication of the person registered in the parameter recording unit 107, that is, the authentication reference similarity, and when the calculated similarity exceeds the authentication reference similarity, the person is confirmed. If the user is confirmed (step S200: Y), the process proceeds to step S300. If the person is not confirmed (step S200: N), an error is displayed on the display unit 106, and the process returns to step S100 again to use the telephone. I can't do it. The identity authentication can be performed more strictly by increasing the authentication standard similarity.

When the person is confirmed (step S200: Y), the telephone number registered in the recognized finger is read from the telephone number recording unit 109 in step S300. In step S400, the name and telephone number of the other party are displayed on the display unit 106. The content displayed on the display unit 106 is confirmed. If it is OK, the telephone number is called / connected in the telephone unit 110 in step S500, the call is made in step S600, and the call is terminated in step S700. .
The above is the outline of the procedure for using the telephone with a fingerprint phone book according to the present invention.

  Next, a method for recognizing which user's finger data is the fingerprint data input from the fingerprint reading unit 103 in step S200 of FIG. 3 and authenticating the fingerprint data will be described in more detail.

FIG. 4 is a detailed flowchart for explaining the recognition and authentication operation in the telephone with a fingerprint phone book.
Of the fingerprint data recognition methods, collation between fingerprint data input from the fingerprint reading unit 103 and all fingerprint data in the database in the fingerprint data recording unit 105 is extracted in order from the top of the database. Explain how to choose the most similar.

  FIG. 7 is a diagram illustrating a data structure example of fingerprint data in a database in the fingerprint data recording unit 105 according to the present embodiment. As shown in the figure, the fingerprint data recording unit 105 includes, for each user, the right hand and the left hand of each thumb, index finger, middle finger, ring finger, little finger fingerprint patterns (FP1 to 10) and their categories (Ci), corresponding A pointer (PTRn) to the number to be stored is stored.

  As shown in FIG. 4, first, in step S220, the number of the fingerprint data read from the fingerprint data recording unit 105 is initialized (x = 0), updated in step S230 (x = x + 1), and in step S240. The x-th fingerprint data is read from the fingerprint data recording unit 105, and in step S250, the fingerprint data read and input from the fingerprint reading unit 103 is compared with the fingerprint data read from the fingerprint data recording unit 105. A measure of similarity or similarity is calculated.

  The method for calculating the similarity is not particularly limited. For example, as described in Japanese Patent Laid-Open No. 5-344217, the input fingerprint data and the stored fingerprint data are overlapped. A method of obtaining the similarity is conceivable.

  If it is the first fingerprint data (x = 1) (step S260: Y), the calculated similarity is stored in the fingerprint data comparison unit 108 as a reference similarity (step S261). Return.

  Next, the next fingerprint data (x = 2) is read from the fingerprint data recording unit 105 (steps S230 and 240). Similarly, the fingerprint data read by the fingerprint reading unit 103 and the input fingerprint data are read from the fingerprint data recording unit 105. The next fingerprint data (x = 2) is compared, and a measure of similarity and degree of similarity are calculated (step S250).

  Since this is not the first fingerprint data (step S260: N), the process proceeds to step 270, where it is determined whether or not the newly calculated similarity is higher than the reference similarity stored in the fingerprint data comparison unit. (Step S270) When the newly calculated similarity is higher than the reference similarity stored in the fingerprint data comparison unit 108 (Step 270: Y), the new similarity is stored in the fingerprint data comparison unit 108. Then, after setting this as a new reference similarity (step S271), the process proceeds to step S280.

  If the newly calculated similarity is not higher than the reference similarity stored in the fingerprint data comparison unit 108 (step S270: N), it is determined in step 280 whether it is the last fingerprint data. If it is not the last fingerprint data (step S280: N), the process returns to step S230, the same processing is performed on the next fingerprint data, and this is repeated until the last fingerprint data in the fingerprint data recording unit 105. In this way, fingerprint data that is most similar to the fingerprint data input from the fingerprint reading unit 103 among all fingerprint data in the fingerprint data recording unit 105 can be obtained.

  When the last fingerprint data is reached (step S280: Y), the reference similarity stored in the fingerprint data comparison unit 108 at that time is set in advance in the parameter recording unit 107 and stored as a reference value for personal authentication. It is determined whether or not it is higher than the authentication reference similarity (step S290). If the reference similarity is higher than the authentication reference similarity (step S290: Y), the reference similarity stored in the fingerprint data comparison unit 108 at that time The fingerprint data for which the degree is obtained is output as recognized and authenticated fingerprint data (step S295), and the process proceeds to step S300 in FIG. 3. If not high (step S290: N), a telephone is used for the fingerprint of the finger. Since this is not possible, the process returns to step S100 in FIG. 3 and the same processing is performed on the other fingers.

  According to this embodiment, when using a telephone terminal, it is not necessary to check the phone book one by one, and it is not necessary to select a registered telephone number like a conventional mobile phone, and it is registered with one finger. Because the phone number can be dialed, the service is improved.

  Next, a description will be given of a method that enables speeding up by searching only in a certain category, instead of taking fingerprint data to be collated in order from the database of the fingerprint data recording unit 105 as in the above-described example. . Recognition is performed according to categories divided by features that can be processed at a relatively high speed during recognition. At that time, recognition is performed in order from the category with the highest similarity. This enables high-speed recognition by appropriately selecting features.

  FIG. 8 is a diagram illustrating a data structure example of fingerprint data stored in the database in the fingerprint data recording unit 105. As shown in the figure, the fingerprint data recording unit 105 includes, for each category, a user, a hand (right hand or left hand), a finger type (thumb, forefinger, middle finger, ring finger, little finger), fingerprint pattern (FPi), A pointer (PTRm) to the corresponding number is stored. And recognition time can be shortened by recognizing in order from the category with high similarity.

In addition, since recognition and authentication must be performed in the present invention, a method of processing at high speed by rejecting those with low similarity without waiting for the recognition result can be considered.
FIG. 5 is a flowchart for explaining preprocessing for rejecting a low similarity without waiting for a recognition result.

  In the flowchart of FIG. 5, step S202 and step S204 are the same as step S220 and step S240 of FIG. In this example, a part of the xth fingerprint data is read from the fingerprint data recording unit 105 in step 206, and a part of the fingerprint data read and input from the fingerprint reading unit 103 and the fingerprint data recording unit in step S208. The similarity is calculated by comparing a part of the fingerprint data read out from 105. As a method for calculating the degree of similarity, the method described above may be used.

  It is determined whether or not the similarity of the calculated xth fingerprint data is higher than a reference value of personal authentication that is preset and stored in the parameter recording unit 107, that is, an authentication reference similarity (step S210). (Step S210: N), the process returns to Step S204, and the same processing is performed on the next fingerprint data in the fingerprint data recording unit 105. If the similarity of the xth fingerprint data is higher than the authentication reference similarity (step S210: Y), the xth fingerprint data is recorded in the fingerprint data recording unit 105 as a rough authentication result (step S212).

  Since this is a pre-process called rough authentication using only a part of fingerprint data, the authentication standard similarity used in step S210 in FIG. 5 is the authentication standard similarity used in step S290 in FIG. Is different. In this way, with respect to fingerprint data whose similarity is too low, it is rejected at that time and detailed recognition is not performed.

  In the rough authentication in the flowchart of FIG. 5, detailed recognition and authentication as shown in FIG. 4 are performed only for the fingerprint data recorded in the fingerprint data recording unit 105 in step S212 without being rejected. Thereby, the recognition and authentication time can be greatly shortened. Furthermore, by using the above-described recognition method for each category together, recognition and authentication can be performed at higher speed.

As a result, calling / connection is performed using the authenticated data obtained.
In FIG. 3, what is sent from step S200 to step S300 is data indicating which user has been authenticated and which finger. Using this data, calling / connection is performed from step S300 to step S500.

FIG. 6 is a detailed flowchart of the processing from step S300 to step S500 in FIG.
In step S340 of FIG. 6, a pointer corresponding to the user name and finger type obtained in the previous stage is obtained from the fingerprint data recorded in the fingerprint data recording unit 105 having the data structure as shown in FIG. 7 or FIG. get.

In the next step S380, the name of the other party (party names P1, P2,...) And the other party's phone number (TEL1, TEL2) corresponding to the pointer obtained from the data recorded in the telephone number recording unit 109 ,...), Information (addressee information info, info2,...) Such as the address of the other party is acquired.
FIG. 9 shows an example of the data structure stored in the telephone number recording unit 109.

In the next step S440, information such as the telephone number and name of the other party obtained from the telephone number recording unit 109 is displayed on the display unit 106.
At this time, when it is not intended to make a call but is used only for confirming the information of the registered other party, if “call / not connect” is set in step S480 (step S480: N), the information is displayed. Can be used for. In step S480, if “call / connect” is set (step S480: Y), or if it is set in advance to automatically call / connect, the telephone number obtained in step S500 is set. This is sent to the telephone unit 110 to call / connect.

  According to the present embodiment, by performing rough fingerprint authentication as pre-processing, the time required for recognition and authentication can be shortened, and further service improvement can be realized.

(Second embodiment)
In the first embodiment described above, a pointer is obtained from fingerprint data, and the pointer is associated with a telephone number. In the second embodiment, one number is designated from the fingerprint data by using the pointer, A multi-digit telephone number is designated by a plurality of pointers.

10 and 11 are flowcharts for explaining the operation of this embodiment.
Next, a method for making a call by designating one number from the fingerprint data by using a pointer and dialing a plurality of digits using a plurality of pointers will be described with reference to FIGS.

  First, in step S1000 of FIG. 10, the number dial mode is switched. As a method of switching to the numeric dial mode, a special switching button may be prepared and switched when the switching button is pressed. Further, the mode may be switched when a finger is pressed for a predetermined time or longer.

  By switching to the numeric dial mode and canceling the numeric dial mode by the above means, the function of the first embodiment can be realized when the numeric dial mode is canceled.

FIG. 12 is a data structure diagram stored in the telephone number recording unit 109 in the second embodiment.
As shown in the figure, the telephone number recording unit 109 stores data in which each pointer is associated with one number. It is possible to make 10 or more pointers correspond to 10 numbers from 0 to 9 by associating a plurality of pointers with the same number (in this case, fingerprint reading operation is seen by others) However, as shown in FIG. 12, if 10 types of pointers and 10 types of numbers are made to correspond one-to-one as shown in FIG. 12, only 10 types of pointers are needed. Therefore, the memory capacity to be used can be reduced. The registration of the data as shown in FIG. 12 in the telephone number recording unit 109 is performed by inputting one digit instead of inputting the telephone number, name, etc. of the other party in steps S50 and S60 in FIG. It can be carried out.

Steps S1100 to S1700 in FIG. 10 are similar to steps S100 to 700 (FIG. 3) in the first embodiment.
That is, when an arbitrary finger is placed on the fingerprint reading unit 103 in step S1100, fingerprint data of the placed finger is captured. In step S1200, fingerprint recognition is performed on the captured fingerprint data, and the most similar fingerprint data is selected from the fingerprint data recording unit 105.

  Subsequently, whether or not the most similar fingerprint data belongs to the user is compared using a reference value for user authentication registered in the parameter recording unit 107 in advance. If the user is confirmed (step S1200: Y), the process proceeds to step S1300. If the person is not confirmed (step S1200: N), for example, an error is displayed on the display unit 106, and the process returns to step S1000 again. In this case, the telephone cannot be used.

  If the user is confirmed (step S1200: Y), in step S1300, the number corresponding to the recognized finger is read from the telephone number recording unit 109 shown in FIG. In step S1400, the number read in step S1300 is displayed on display unit 106. The entered number is confirmed (step S1442). If it is not correct (step S1442: N), the entered number is canceled (step S1446), and the process returns to step S1100. If the input number is correct (step S1442: Y) and the input of the number corresponding to the telephone number is not completed (step S1450: N), the process returns to step S1100 and the same processing is repeated.

When the input of the number corresponding to the telephone number is completed (step S1450: Y), it is confirmed. If so, the telephone unit 110 calls / connects the telephone number in step S1500, and the telephone is called in step S1600. When the call is finished, the call is disconnected in step S1700.
The above is the outline of the procedure for using the telephone with a fingerprint telephone directory according to the second embodiment of the present invention.

  FIG. 11 is a detailed flowchart of the processing from step S1300 to step S1500 in FIG. 10, and is similar to the processing from step S300 to step S500 in the first embodiment.

  That is, in step S1340 of FIG. 11, the pointer corresponding to the user name and the finger type is acquired from the fingerprint data recorded in the fingerprint data recording unit 105 as in the case of the first embodiment. In the next step S1380, one number corresponding to the obtained pointer is obtained from the data recorded in the telephone number etc. recording unit 109 as shown in FIG.

  In the next step S 1440, the numbers obtained from the telephone number recording unit 109 are displayed on the display unit 106. If the entered number is wrong (step S1442: N), a cancel button is prepared, and by pressing the cancel button, the device is informed that the entered number is incorrect and the number is deleted. (Step S1446), the process returns to step S1100.

  The above processing is repeated until the input is completed (step S1450: N, step 1448). The input may be ended when a special end button is prepared and the end button is pressed. Moreover, you may make it complete | finish when there exists pressing of the finger | toe more than a certain time.

  The number displayed on the display unit 106 is confirmed, and if the displayed number is incorrect, “call / not connect” may be set in step S1480. At this time, the process returns to step S1000. On the other hand, if the input number is correct, in step S1480, if “call / connect” is set, or if it is set in advance to automatically call / connect, in step S1500, The obtained telephone number is sent to the telephone unit to call / connect.

  Each processing step of the fingerprint identification input method for identifying the fingerprint and calling the other party corresponding to the fingerprint is converted into a program code and recorded on a recording medium such as a DVD, CD-ROM, or FD. By distributing in the market, it is possible to provide a very convenient service for the user.

Next, an implementation example of the present invention will be described with reference to the drawings.
FIG. 13 is an implementation example of a wired telephone, and shows a form realized by an ordinary wired telephone or a public telephone. This figure shows an example in which a display unit 106, a key rotation unit 102, and a fingerprint reading unit 103 are separately provided on the right side of the installation unit of the telephone unit (handset) 110.

  FIG. 14 shows another implementation example of the wired telephone, in which the display unit 106, the key operation unit 102, and the fingerprint reading unit 103 are realized on one screen. Thus, in addition to fingerprint reading, if the XY coordinates of the point where the finger is pressed can be read, the telephone number to be read can be changed depending on the coordinates even for the same finger of the same user.

  In this case, for example, the fingerprint data recording unit 105 divides the coordinate position on the screen serving as the fingerprint reading unit 103 into a plurality of parts (for example, four divisions such as upper right, lower right, upper left, and lower left), and the divided coordinate positions It is conceivable to store a separate telephone number correspondence table for each. In addition, if each divided area is divided by displaying a frame or the like, it is easy for the user to use.

  Note that the telephone with a fingerprint phone book of the present invention is not necessarily a telephone for voice calls, but may be a communication terminal such as a facsimile machine or a portable terminal used for mobile communication.

  According to the present embodiment, if a single digit is not a phone number corresponding to a single finger, a non-registered phone number can be entered in the order of ten-finger pressing, and the telephone is configured. This is advantageous for saving space.

Next, an implementation example of a portable telephone with a telephone directory will be described.
FIG. 15 shows an implementation example of a mobile phone, and a display unit 106, a key operation unit 102, and a fingerprint reading unit 103 are separately provided as in FIG.
FIG. 16 shows another example of expression of a mobile phone, in which a display unit 106, a key operation unit 102, and a fingerprint reading unit 103 are provided on one screen, as in FIG. According to this configuration, if one fingerprint reading unit 103 is provided, numbers can be input or telephone numbers can be read out. Therefore, the present invention is effective when used for a small mobile phone in which no input button can be arranged.

FIG. 17 shows an implementation example of a wristwatch-type mobile phone, in which a display unit 106, a key operation unit 102, and a fingerprint reading unit 103 are provided separately as in FIG.
FIG. 18 shows another example of realization of a wristwatch-type mobile phone, in which a display unit 106, a key operation unit 102, and a fingerprint reading unit 103 are provided on one screen as in FIG.

Next, another embodiment of the present invention will be described. In these embodiments, a telephone with a fingerprint telephone book will be described as an example of a fingerprint identification information terminal.
The third embodiment of the present invention is an embodiment for inputting characters (including numbers) and symbols corresponding to the touched finger or direction, and the fourth embodiment is a direction corresponding to the touched finger or direction. In this embodiment, characters (including numbers) and symbols are searched, determined, and input, and the fifth embodiment is an embodiment in which the mouse pointer is operated in correspondence with the finger or direction touched.

  In the third embodiment, the fourth embodiment, and the fifth embodiment described below, the feature extraction method, the fingerprint recognition method, the person recognition method, the usage forms as shown in FIGS. Since this is the same as that described in the first embodiment, detailed description thereof will be omitted. These embodiments can be applied to all general information terminal devices other than the telephone with a fingerprint input device.

(Third embodiment)
In the present embodiment, input of characters (including numbers) and symbols in a telephone with a fingerprint input device is taken as an example. When using a telephone with a fingerprint phone book, it is necessary to register fingerprint data in advance.

First, a method for registering fingerprint data will be described.
The user name, the finger information of how many fingers, and the direction of the finger to be registered are registered. Alternatively, registration may be performed in one direction, and data may be created in a plurality of directions (for example, four directions, up, down, left, and right), or more directions.

  The reason for registering the direction is that even if the finger is the same, the fingerprint pattern registered in the registration device is registered as different character or symbol data when the direction is changed, such as when the finger is placed upward or downward. It is for doing so. When a user name is input, guidance is displayed, and characters (including numbers) and symbols are registered in accordance with the fingerprints of the fingers of both hands according to the guidance. At this time, when the fingerprints of the fingers of both hands are input in order, characters (including numbers) and symbols may be automatically registered in a predetermined order.

FIG. 19 is a flowchart for registering a fingerprint according to the guidance.
Hereinafter, the procedure for fingerprint registration will be described with reference to FIG.
In step T <b> 10, a user name is input from the key operation unit 102.
In step T20, the finger to be registered is displayed on the display unit 106.
In step T <b> 30, a finger to be registered in the fingerprint reading unit 103 is placed, and fingerprint data is input from the fingerprint reading unit 103.
In step T40, it is determined whether or not the fingerprint data has been normally input. If the fingerprint data has not been normally input, the process returns to step T30 and the fingerprint data is input again.

  When the fingerprint data is normally input at step T40 (step T40: Y), the next finger is registered at step T50. The procedure of Step T50 is the same as that of Step T20 to Step T40, and the fingerprint data of the finger to be registered displayed on the display unit 106 is sequentially input.

  Next, in step T60, it is determined whether or not it is the last finger. If it is not the last finger, the process returns to step T50. The process from step T50 to step T60 is repeated until all ten fingers are registered.

  When all ten fingers have been registered (step T60: Y), and all have been normally performed (step T70: Y), YES is input from the key operation unit 102, and the registration is completed. If correction is desired, NO is input from the key operation unit 102, the process returns to step T10, and registration is started again from the beginning. When the registration is completed, various features are extracted from the fingerprint data by the fingerprint feature extraction unit 104.

  Next, an outline of a procedure for using a fingerprint identification information terminal (phone with a fingerprint input device) will be described. In recent years, telephones having an electronic mail function are increasing, and the necessity of character input is increasing. Here, an outline of a character input operation applied to such a telephone with a fingerprint input device will be described.

  Since the fingerprint data of both hands only has data for ten fingers, it cannot correspond to more than ten characters. Therefore, in this embodiment, ten-finger fingerprint data is associated with 10 or more characters using the following three types of methods (a) to (c).

(A) A method of associating the type of finger placed on the fingerprint reading unit, the direction in which the finger is placed, and letters (including numbers) and symbols.
(B) A method of associating the order of fingers placed on the fingerprint reading unit with characters (including numbers) and symbols.
(C) A method of providing two or more fingerprint reading units and associating the combination with characters (including numbers) and symbols.

  First, “a method of associating the type, direction, and character of the finger placed on the fingerprint reading unit” of (a) will be described. As a specific example for realizing this method, for example, the line indicating which finger type is “Akasana ...” is associated with the direction of the finger so as to indicate a stage “Aiueo”. That is, the “little finger”, “ring finger”, “middle finger”, “index finger”, “thumb” of the left hand are respectively “a line”, “ka line”, “sa line”, “ta line”, “na line”. The right thumb “thumb”, “index finger”, “middle finger”, “ring finger”, “little finger” are “ha line”, “ma line”, “ya line”, “ra line”, “wa line”, respectively. The direction of the finger (5 step angles) corresponds to “Adan”, “Idan”, “Udan”, “Edan”, “Odan”. Information on these associations is registered from the key operation unit 102.

  In this way, when the right index finger is placed in the right direction, the right index finger represents a combination of “ma line” in “Akasana ...” and a right direction in “Aueo”. You can specify "Mu". According to this method, the finger can be put only once, which is convenient. Note that “n” is not used for the association. For example, it may be associated with “dan” of “wa line”. The association between the finger type and the direction is not limited to the above method, and may be applied to any character. Since the above method cannot be used especially for English characters, it is assigned arbitrarily. Switching between English characters, Japanese characters, symbols, and the like is performed by the key operation unit 102.

Next, a specific procedure for realizing the method (a) will be described in detail with reference to the flowchart of FIG.
First, in step T100, when a finger is placed on the fingerprint reading unit 103, fingerprint data of the placed finger is captured. Fingerprint recognition is performed on the captured fingerprint data in step T200, and the most similar fingerprint data is selected from the fingerprint data recording unit 105. At this time, the kind and direction of the finger are also recognized.

  Subsequently, in step T300, whether or not the most similar fingerprint data belongs to the user is compared using a reference value for user authentication registered in the parameter recording unit 107 (see the description of the first embodiment).

  The recognition of the kind and direction of the above-mentioned finger and the authentication of the person are pasted on the finger so that a part of the fingerprint to be registered is exposed through the window, as disclosed in, for example, JP-A-2-245980. A fingerprint input means for inputting a fingerprint exposed from the window of the seal, a feature point extraction means for obtaining a pattern and coordinates of a feature point supplied with a fingerprint image from the fingerprint input means, and a fingerprint image from the fingerprint input means Rotation and translation detecting means for calculating a deviation rotation angle from a predetermined reference orientation and a translation amount of deviation from a predetermined reference position based on the contour of the corresponding fingerprint image portion, and controlling the fingerprint input means And a control means for inputting a plurality of fingerprints to a single registered fingerprint to form a plurality of input fingerprint images, and a plurality of fingerprint input images corresponding to a single registered fingerprint with the rotation angle and displacement translation. And corresponding feature point detection in which an image of feature points whose degree of coincidence of feature point patterns is equal to or greater than a predetermined threshold value is registered in the dictionary based on the reference azimuth and reference position. This can be realized by a fingerprint collation device comprising image registration means (see FIGS. 7 and 8 of the publication).

  If the identity is confirmed by the identity authentication (step T300: Y), the process proceeds to step T400. If the identity is not confirmed (step T300: N), an error is displayed on the display unit 106, and the process returns to step T100 to Cannot be used. Note that the identity verification process in step T300 may be performed in a sampling manner instead of every time a fingerprint is read. In an extreme case, the identity verification processing is performed at the time of reading the first fingerprint. Even without it, there is an effect of identity verification.

  In step T400, the character corresponding to the recognized finger type and direction is read from the telephone number recording unit 109. In step T500, the character corresponding to the fingerprint data is displayed on the display unit 106. In step T600, it is determined whether or not the input is correct. If the input is not correct (step T600: N), NO is input from the key operation unit 102, the process returns to step T100 and the input is performed again for correction. If the input is correct (step T600: Y), YES is input from the key operation unit 102, and the next character input is started. Or, unless NO is input from the key operation unit 102, the operation can be further easily and quickly performed by automatically shifting to the input of the next character.

  Next, the “method of associating the order of the finger placed on the fingerprint reading unit and the character” of (b) will be described. As an example of this, for example, the line of which one of the finger types of the first finger “Akasana ...” is associated with the row of the finger type of the second finger “Aiueo”. Information on these associations is registered from the key operation unit 102.

  In other words, if you put your right index finger on the first one, the right index finger will correspond to “Ma row” in “Akasana ...”, and if you put your right middle finger on the second one, “Udan” in “Aiueo” It may be determined that “Mu” is a combination that represents Note that “n” is not used for the association. For example, it may be associated with “dan” of “wa line”. The association of the finger types is not limited to the above method, and may be applied to any character. Since the above method cannot be used especially for English characters, it is assigned arbitrarily. Switching between English characters, Japanese characters, symbols, and the like is performed by the key operation unit 102.

Next, a specific procedure for realizing the method (b) will be described with reference to the flowchart of FIG.
In step T110, when the first finger is placed on the fingerprint reading unit 103, fingerprint data of the placed finger is captured. In step T <b> 210, fingerprint recognition is performed on the captured fingerprint data, and the most similar fingerprint data is selected from the fingerprint data recording unit 105.

  Subsequently, whether or not the most similar fingerprint data belongs to the user is confirmed by comparison in step T310 using the reference value of the user authentication registered in the parameter recording unit 107. If the user is confirmed (step T310: Y), the process proceeds to step T410. If not confirmed (step T310: N), an error is displayed on the display unit 106, the process returns to step T110, and the apparatus cannot be used. .

  In step T410, when the next arbitrary finger (second finger) is placed on the fingerprint reading unit 103, fingerprint data of the placed finger is captured. Fingerprint recognition is performed on the captured fingerprint data in step T510, and the most similar fingerprint data is selected from the fingerprint data recording unit 105. The finger type is recognized. Subsequently, it is compared and confirmed in step T610 using the reference value of the personal authentication registered in the parameter recording unit 107 to determine whether or not the fingerprint data belongs to the person in the most similar manner.

  If the user is confirmed (step T610: Y), the process proceeds to step T710. If not confirmed (step T610: Y), an error is displayed on the display unit 106, the process returns to step T110, and the apparatus cannot be used. . The identity verification process in steps T310 and T610 may be performed in a sampling manner instead of every time a fingerprint is read. In extreme cases, it is performed at the time of the first fingerprint reading. There is an effect of identity verification even if it is not performed.

  In step T710, the character corresponding to the recognized finger type is read from the telephone number recording unit 109. In step T810, characters corresponding to the fingerprint data are displayed on the display unit 106. Whether or not the input is correct is determined by looking at the display. If the input is not correct, NO is input from the key operation unit 102 in step T910, and the process returns to step T110 to correct the input again. If the input is correct, YES is entered from the key operation unit 102, and the next character is entered. Or, unless NO is input from the key operation unit 102, the operation can be further easily and quickly performed by automatically shifting to the input of the next character.

Next, (c) “method of providing two or more fingerprint reading units and associating the combination with characters” will be described.
For example, in the method (c), two fingerprint readers are provided on the left and right, and the type of ten fingers of both hands placed on the fingerprint reader on the left is changed to the right side of “Akasana ...” The finger type placed on the fingerprint reading unit is associated with one of “Aiueo”. Information on these associations is registered from the key operation unit 102.

  For example, if you place your left index finger on the left fingerprint reader, the left index finger will correspond to “Ta line” in “Akasana ...”, and then place your right hand middle finger on the right fingerprint reader. May be determined as “tsu” in a combination representing “Udan”. Note that “n” is not used for the association. For example, it may be associated with “dan” of “wa line”. The association of the finger types is not limited to the above method, and may be applied to any character. Since the above method cannot be used especially for English characters, it is assigned arbitrarily. Switching between English characters, Japanese characters, symbols, and the like is performed by the key operation unit 102.

Next, a specific procedure for realizing the method (c) will be described with reference to the flowchart of FIG.
In step T120, when a finger is placed on the left fingerprint reading unit 103, fingerprint data of the placed finger is captured. Fingerprint recognition is performed on the captured fingerprint data in step T220, and the most similar fingerprint data is selected from the fingerprint data recording unit 105. Similarly, in step T320, when it is placed on the right fingerprint reading unit, fingerprint data of the placed finger is captured.

  Fingerprint recognition is performed on the captured fingerprint data in step T420, and the most similar fingerprint data is selected from the fingerprint data recording unit 105. Subsequently, whether or not the most similar fingerprint data belongs to the user is compared in step T520 using the user authentication reference value registered in the parameter recording unit 107, and identity verification is performed.

  If both the left and right data are confirmed as the person (step T520: Y), the process proceeds to step T620. If not confirmed (step T520: N), an error is displayed on the display unit 106, the process returns to step T120, and the device is turned on. Cannot be used. The identity verification process in step T520 may be performed in a sampling manner instead of every time a fingerprint is read. In extreme cases, it is performed at the time of reading the first fingerprint. Even without it, there is an effect of identity verification.

  In step T620, the character corresponding to the recognized finger type is read from the telephone number recording unit 109. In step T720, the character corresponding to the fingerprint data is displayed on the display unit 106. If the input is not correct (step T820: N), NO is input from the key operation unit 102 at step T820, and the process returns to step T120 and is input again for correction. If the input is correct (step T820: Y), YES is input from the key operation unit 102, and the process proceeds to input of the next character. Or, unless NO is input from the key operation unit 102, the operation can be further easily and quickly performed by automatically shifting to the input of the next character.

(Fourth embodiment)
Next, a fourth embodiment of the present invention that searches, determines and inputs characters (including numbers) and symbols arranged in a predetermined order in the finger touched or in the direction associated with the direction of the finger. explain. As in the first to third embodiments described above, a description will be given by taking character input as an example using a telephone with a fingerprint input device. As in the first to third embodiments described above, description will be made by taking an example of inputting characters using a telephone with a fingerprint input device. Before using the telephone with a fingerprint input device, it is necessary to register fingerprint data in advance. First, a method for registering fingerprint data will be described.

  Since the fingerprint data registration method is the same as that of the third embodiment described above, it will be described with reference to FIG. In the third embodiment, the fingerprint pattern and the character are associated with each other. In the fourth embodiment, the fingerprint pattern and the direction are associated with each other. Here, a method of registering two directions (forward direction or reverse direction) will be described. In step S20, the finger to be registered is displayed on the display unit 106. Here, the finger is displayed to register the forward search finger and the backward search finger.

  Here, the forward search finger and the backward search finger will be described. The forward search finger and the reverse search finger may be associated with different fingers, or may be associated with the same finger whose direction is changed. For example, the thumb (regardless of direction) may be associated with the forward search finger, and the index finger (regardless of direction) may be associated with the backward search finger. The index finger thus made may be associated with the backward search finger.

  As an operation example, it is assumed that data of characters and symbols are arranged in a predetermined order as shown in FIG. When the forward search finger is put on the fingerprint reading unit 103, the database shown in FIG. 23 is searched from the top to the bottom. When the backward search finger is put on the fingerprint reading unit 103, the database shown in FIG. To do. Decide by releasing your finger when the desired character is displayed.

The specific procedure of the present embodiment will be described using the flowchart of FIG.
In step U100, when a finger is placed on the fingerprint reading unit 103, fingerprint data of the placed finger is captured. In step U200, fingerprint recognition is performed on the captured fingerprint data, and the most similar fingerprint data is selected from the fingerprint data recording unit 105. Subsequently, in step U300, whether or not the most similar fingerprint data belongs to the user is compared using a reference value for user authentication registered in the parameter recording unit 107.

  If both the left and right data are confirmed as the person (step U300: Y), the process proceeds to step U400. If not confirmed (step U300: N), an error is displayed on the display unit 106, the process returns to step U100, and the device is turned on. Cannot be used. Note that the identity verification process in step U300 may be performed in a sampling manner instead of every time a fingerprint is read. In extreme cases, it is performed at the time of reading the first fingerprint. Even without it, there is an effect of identity verification.

  In step U400, the fingerprint data of the finger placed on the fingerprint reading unit 103 is compared with the registered fingerprint data of the forward search finger. As a result of the comparison, if the finger placed on the fingerprint reading unit 103 is confirmed as a forward search finger (step U400: Y), the process proceeds to step U600, and the first character from the database shown in FIG. Read from the recording unit 109 and display on the display unit 106. If the character is not a character to be input, NO is input from the key operation unit 102 in step U800, and the process returns to step U100.

  When step U600 is reached again, the second character from the top of the database shown in FIG. 23 is read from the telephone number recording unit 109 and displayed on the display unit 106. This is repeated, and the procedure from step U100 to step U800 is repeated until the desired character is displayed. When the desired character is displayed, in step U800, YES is entered from the key operation unit 102 to determine the character to be entered.

  On the other hand, in step U400, the fingerprint data of the finger placed on the fingerprint reading unit 103 is compared with the registered fingerprint data of the backward search finger. As a result of the comparison, if the finger placed on the fingerprint reading unit 103 is confirmed as a backward search finger, the process proceeds to step U700 to search the database in FIG. 23 in order from the bottom to the top. The detailed operation at this time is the same as that described in step U600 except that the database search order shown in FIG. 23 is reversed. Further, by using a forward search finger and a backward search finger together, it is possible to perform an easier search.

  In step U800, unless YES is input from the key operation unit 102 within a predetermined time, it is more convenient and convenient to return to step U100 automatically. In this method, authentication must be repeated many times. However, if a mechanism for measuring the time during which the finger is placed on the fingerprint reading unit 103 is provided, candidate characters are displayed one after another only during the time the finger is placed. When the desired character is displayed, the input character can be determined more easily by determining the input character by separating the finger from the fingerprint reading unit 103.

(Fifth embodiment)
Next, a description will be given of a fifth embodiment of the present invention in which the mouse pointer is operated corresponding to the touched finger or direction. Here, the mouse pointer is a pointer that moves in a corresponding direction by instructing the direction by any method including a cross cursor used for a mobile phone, and has a function of indicating a character position or the like. Similar to the fourth embodiment described above, this embodiment will be described by taking a telephone with a fingerprint input device as an example.

  In order to make a call to a registered telephone number using a telephone with a fingerprint input device, it is necessary to register fingerprint data in advance before use. First, a method for registering fingerprint data will be described.

  In this embodiment, the fingerprint pattern is associated with the moving direction of the mouse pointer. Here, a method for registering four moving directions will be described. In step T20 of FIG. 19, the finger to be registered is displayed on the display unit 106. In this embodiment, the finger is displayed to register the upward moving finger, the downward moving finger, the left moving finger, and the right moving finger. . The upward moving finger, the downward moving finger, the left moving finger, and the right moving finger may correspond to different fingers, or may correspond to the same finger whose direction is changed.

  For example, the right index finger is the upward movement finger, the right hand middle finger is the downward movement finger, the right ring finger is the left movement finger, the right hand little finger is the right movement finger, or the right hand index finger is placed upward It is possible to make the upward movement finger correspond to the downward movement finger, the left movement finger to correspond to the left movement finger, and the right movement finger to correspond to the right movement finger.

  Further, the moving speed of the mouse pointer may be determined in a plurality of stages such as low speed, medium speed, and high speed, and registration may be performed with more detailed settings such as an upper high-speed moving finger and a lower low-speed moving finger. For example, it is possible to use a low speed movement when inputting the moving direction with the index finger and a high speed moving when inputting the moving direction with the middle finger.

Next, a specific procedure of the present embodiment will be described using the flowchart of FIG.
In step V100, when a finger is placed on the fingerprint reading unit 103, fingerprint data of the placed finger is captured. Fingerprint recognition is performed on the captured fingerprint data in step V200, and the most similar fingerprint data is selected from the fingerprint data recording unit 105. Subsequently, whether or not the most similar fingerprint data belongs to the user is compared in step V300 using the reference value of the user authentication registered in the parameter recording unit 107.

  If both the right and left data are confirmed as the person (step V300: Y), the process proceeds to step V400. If not confirmed (step V300: N), an error is displayed on the display unit 106, the process returns to step V100, and the device is turned on. Cannot be used. Note that the identity verification processing in step V300 is not necessarily performed every time a fingerprint is read, and may be performed in a sampling manner. In extreme cases, it is performed at the time of reading the first fingerprint. There is an effect of identity verification even if it is not performed.

  In step V400, the fingerprint data of the finger placed on the fingerprint reading unit 103 is compared with the data of the upward moving finger. If the finger placed on the fingerprint reading unit 103 is confirmed as an upward movement finger (step V400: Y), the process proceeds to step V500, and the mouse pointer moves upward.

  In step V400, if the finger placed on the fingerprint reading unit 103 is not confirmed as an upward moving finger (step V400: N), the process proceeds to step V600. In step V600, the fingerprint data of the finger placed on the fingerprint reading unit 103 is compared with the data of the downward moving finger. If the finger placed on the fingerprint reading unit 103 is confirmed as a downward movement finger (step V600: Y), the process proceeds to step V700, and the mouse pointer moves downward. If the finger placed on the fingerprint reading unit 103 is not confirmed to be a downward movement finger in Step V600 (Step V600: N), the process proceeds to Step V800.

  In step V800, the fingerprint data of the finger placed on the fingerprint reading unit 103 is compared with the data of the left moving finger. If the finger placed on the fingerprint reading unit 103 is confirmed to be a leftward moving finger (step V800: Y), the process proceeds to step V900, and the mouse pointer moves to the left. If the finger placed on the fingerprint reading unit 103 is not confirmed as a leftward moving finger in Step V800 (Step V800: N), the process proceeds to Step V1000.

  In step V1000, the fingerprint data of the finger placed on the fingerprint reading unit 103 is compared with the data of the right moving finger. If the finger placed on the fingerprint reading unit 103 is confirmed as a rightward moving finger (step V1000: Y), the process proceeds to step V1100, and the mouse pointer moves to the right. In step V1000, if the finger placed on the fingerprint reading unit 103 is not confirmed as a rightward moving finger (step V1000: N), the process returns to step V100.

  In this example, fingerprint data corresponding to four directions of “upper”, “lower”, “left”, and “right” is registered. However, if data of eight directions or more is registered, the mouse can be more easily registered. The pointer can be moved freely in any direction.

  As described above, in this embodiment, the operation direction (for example, upper, lower, right, left, etc.) with limited number of candidates, the operation speed (for example, low speed, medium speed, high speed, etc.) It is possible to register the correspondence relationship of the set of directions in advance and move the mouse pointer according to the finger placed on the fingerprint reading unit 103 and the moving direction and moving speed registered in association with the direction.

  Also, if the fingerprint reading unit 103 is provided with a mechanism for measuring the time during which the finger is placed, the mouse pointer can be automatically moved only during the time when the finger is placed. Becomes easier. When characters are displayed in a two-dimensional array, the mouse pointer is moved, and the desired character is displayed, the finger is released from the fingerprint reading unit 103 or a decision is input from the key operation unit 102 If so, it is possible to input characters and symbols as in the fourth embodiment.

  In the above, the input of phone numbers, letters (including numbers), symbols, etc. using the fingerprint of a finger has been described, and an example of verifying the identity based on the feature points of the fingerprint has been described. It can be used in the same way as a password.

  That is, as described above, after the registration of each finger and its direction is completed, the user's presentation order is input for the pair of the finger and its direction, and the input presentation order is the user-specific information (password code). ) In advance.

  When verifying the identity associated with a call or input, the user is asked to enter the order of presentation for the pair of fingers and their directions, the entered presentation order is compared with the registered presentation order, and permission is granted if they match. To do. According to this method, the character string or symbol string to be entered is not known to anyone other than the person, so authenticating a pair of a single finger and its direction makes it as secure as conventional identity verification using a personal identification number. The sex can be remarkably improved.
