Description

  The present invention is applied to, for example, a communication terminal suitable for application to a mobile phone terminal capable of data transfer with a nearby terminal by short-range wireless communication, a communication system including the communication terminal, and the communication system. It relates to a communication method.

2. Description of the Related Art Conventionally, various communication terminals such as mobile phone terminals that have a short-range wireless communication function and can transfer data between two adjacent terminals have been put into practical use.
For example, a mobile phone terminal has a short-range wireless communication function by transmitting and receiving infrared signals, and by transmitting and receiving infrared signals between two adjacent mobile phone terminals, the phone number and mail address of the terminal, or the terminal Transferring phone book data registered in is performed.

  However, if data can be transferred to other devices simply by touching the touch panel in this way, there is a possibility that data may be transferred to other terminals by chance even during operations not intended by the user. That is, when a user who operates one terminal performs a touch operation that performs transmission, data is transferred when another user who operates the other terminal accidentally performs a touch operation that performs reception. End up. The ease of operation that allows data to be transferred to other terminals simply by touch panel operation is preferable from the ease of operability during data transfer, but data transfer unintended by the user of such a terminal may occur. This is a problem in managing data.

  The present invention has been made in view of such a point, and an object thereof is to enable easy and reliable data transfer to a nearby terminal by an operation using a touch panel.

  The present invention is applied to a case where data transfer is performed between a first terminal and a second terminal. As the processing, the fingerprint data detected by touching the touch panel provided in the first terminal is held, and the fingerprint data detected by touching the touch panel provided in the second terminal is transmitted to the first terminal. To do. Then, the fingerprint data held in the first terminal is collated with the transmitted fingerprint data. When a match is detected by the collation, the predetermined data held by the first terminal is transferred to the second terminal.

  With this configuration, the authentication processing between the two terminals is completed by touching the touch panels of the two terminals in order with the same finger of the same user, and data is transferred between the two terminals. Transfer will be performed.

  According to the present invention, since one user touches both the touch panel of the transfer source terminal and the touch panel of the transfer destination terminal in order, data transfer is performed between both terminals. Can be transferred. In particular, since fingerprints are collated between two terminals, data transfer is not performed when the user touching the touch panel of the two terminals is different, so that data is transferred to another nearby terminal by mistake. Data can be managed appropriately.

Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.
FIG. 1 is a diagram showing an outline of a system configuration example according to the present embodiment. In the present embodiment, a plurality of information display terminals T10, T11, T12 are prepared. Here, the information display terminals T10, T11, and T12 are mobile phone terminals, and the information display terminals T10, T11, and T12 can transfer data via communication means. As a communication means for performing data transfer, a wireless telephone communication network is applicable. Alternatively, a wireless communication unit that performs short-distance wireless communication with a limited wireless communication range, such as infrared wireless communication, wireless communication for wireless LAN, or Bluetooth (trademark) may be applied.

  Each information display terminal T10, T11, T12 has a configuration including a touch panel. Although the configuration of the touch panel will be described later, it is a panel including a display unit 17 and an image reading unit 19. The image reading unit 19 functions as a fingerprint detection unit that reads a fingerprint touched on the panel.

A plurality of information display terminals T10, T11, T12 shown in FIG. 1 are arranged at relatively close positions. In the example of FIG. 1, the information display terminal T10 and the information display terminal T11 indicate a situation in which the same user U10 is operating the display unit 17 as a touch panel. The situation where the user U11 is operating the display unit 17 as a touch panel is shown.
In the present embodiment, in such an operation situation, data transfer is performed between the two information display terminals T10 and T11 operated by the same user U10. Further, data transfer is not performed between terminals with different operating users, for example, between the information display terminal T10 and the information display terminal T12 shown in FIG.

  FIG. 2 is a diagram showing a configuration example of the information display terminal 10 corresponding to each information display terminal T10, T11, T12. The information display terminal 10 shown in FIG. 2 shows only the configuration necessary for the processing in the present embodiment. For example, the information display terminal 10 is used for calling when the information display terminals T10, T11, and T12 are configured as mobile phone terminals. These processing circuits are omitted.

  Referring to FIG. 2, the configuration of the information display terminal 10 includes a central control unit (CPU) 11 that controls information processing. The central control unit 11 includes a ROM 12, a RAM 13, and a hard disk drive device 14 via an internal bus 15. And connected. The ROM 12 stores a program (software) that performs control processing. This program includes a program for controlling data transfer, which will be described later. Terminal-specific data such as the terminal ID is also stored in the ROM 12. The RAM 13 is used as a work memory for executing control processing, and temporarily stores various data. Various tables to be described later are also configured by storage in the RAM 13. The hard disk drive device 14 is used as a data storage unit for storing data. For example, the hard disk drive device 14 stores data to be transferred to another terminal and stores data transferred from the other terminal. Instead of the hard disk drive device 14, another storage means such as a semiconductor memory may be used.

An optical sensor built-in display control driver 16 is connected to the internal bus 15, and the display control driver 16 controls display of images and characters on the display unit 17. For example, a liquid crystal display panel or an organic EL (Electro Luminescence) panel can be applied to the display unit 17.
A touch detection unit 18 and an image reading unit 19 are incorporated in the panel constituting the display unit 17. When the surface of the display unit 17 is touched with a finger or the like, the touch detection unit 18 detects the touched coordinate position (touch position). The image reading unit 19 is means for reading the surface of an object touched by the display panel or an object close to the display panel. The touch detection unit 18 and the image reading unit 19 are integrated into the display unit 17.

In the present embodiment, the image reading unit 19 is used to detect a fingerprint of a finger touching the display panel surface. The information of the image read by the image reading unit 19 is sent to the display control driver 16 with a built-in optical sensor, and fingerprint detection processing is performed from the image detected with the display control driver 16 with a built-in optical sensor. Fingerprint data and touch position data detected by the display control driver 16 with a built-in optical sensor are sent to the central control unit 11.
The central control unit 11 performs control processing for data transfer based on touch position data and fingerprint data.

  The information display terminal 10 includes the communication unit 20 and can perform transmission processing for sending data to the network 30 and can also receive data obtained by the communication unit 20 via the network 30. Communication processing in the communication unit 20 is executed based on the control of the central control unit 11. As described above, as the communication unit 20, in addition to the communication unit for connecting to a wireless telephone communication network, various short-distance wireless communication units can be applied.

Next, an example of data transfer processing in the information display terminal 10 of the present embodiment will be described with reference to the flowcharts in FIG.
In the present embodiment, data is transferred to and from other nearby terminals by a touch operation on the touch panel constituting the display unit 17.

The flowchart of FIG. 3 shows an example of processing when touch detection on the touch panel. This process is executed based on the control of the central control unit 11. When performing data transfer by this touch operation, the user performs an operation of touching the display panel with a finger.
When touched with a finger in this way, when it is detected by the touch detection unit 18 that a certain object has been touched (step S11), information on the touched position (touch position) is acquired (step S12). .
When the touch position is detected, it is displayed on the display unit 17 that the touch transfer is started, and it is determined whether or not the touch transfer is selected by a user operation based on the display (step S13). If touch transfer is not selected, the process proceeds to step S25 and the process is terminated.

If touch transfer is selected in step S13, a fingerprint reading process is performed based on the output of the image reading unit 19 (step S14). The read fingerprint image data is supplied to the central control unit 11 to generate a fingerprint ID which is fingerprint identification data, and the fingerprint ID is stored in the RAM 13 (step S15).
As the fingerprint ID, the fingerprint image data itself may be used, or a hash value such as MD5 (Message Digest Algorithm 5) may be obtained from the fingerprint data and used as the fingerprint ID.

Thereafter, it is determined whether there is an operation for selecting data to be transferred from the information displayed on the display panel (step S16). For example, when some data is displayed at the touch position selected in step S12, this selection operation is handled as the selected data. Alternatively, for example, a list of data that can be transferred may be displayed on the display unit 17 and the selection process may be performed.
If it is determined that the data is selected in step S16, a data ID (for example, a file name) of the selected data is acquired (step S17), and the fingerprint ID obtained in step S15 and the data ID obtained in step S17 are associated with each other. It is registered in the RAM 13 as a management table (step S18).
When the processing so far is completed, an operation completion notification is transmitted from the communication unit 20 to the network 30 under the control of the central control unit 11 (step S19). At the time of transmission of the operation completion notification, its own terminal ID is added as a transmission source ID to the operation completion notification data. Further, the transmission destination ID is not specified. However, when the ID of a nearby terminal is known in advance by another process, the transmission destination ID may be added. The transmission of the operation completion notification ends the touch detection process at the transmission source (step S25).

Next, the processing when there is no data selection in step S16 (that is, processing on the data receiving side) will be described with reference to the flowchart of FIG.
If it is determined in step S16 that no data is selected, the central control unit 11 determines whether or not the communication unit 20 has already received an operation completion notification transmitted from another terminal (step S20). ). If an operation completion notification has not been received, it is determined that there is no data to be transferred to the terminal itself, and the process here ends.
If an operation completion notification has been received, a data request is transmitted to the terminal having the transmission source ID indicated by the operation completion notification (step S21). At this time, the fingerprint ID generated in step S15 is added. Thereafter, the communication unit 20 waits until data addressed to the terminal is received (step S22).

  If the data is received in step S22, it is determined whether or not the data has been received normally (step S23). If the data has been received, the received data is stored, and the data is displayed at the touch position detected in step S12. Is displayed (step S24). The data to be displayed is the data name of the received data or the text or image of the data. By displaying the received data, the touch process here is terminated (step S25). Even in the case where reception is not normal in step S23, the touch processing here ends.

Next, processing when the data request message in step S21 in the flowchart of FIG. 3 is received by the data transmission source terminal will be described with reference to the flowchart of FIG. This process is also executed under the control of the central control unit 11 in the terminal. This process is started when a data request message is received (step S31). First, the fingerprint ID included in the data request message is taken out, and whether or not the fingerprint ID exists in the data management table is checked. If there is a matching fingerprint ID, the fingerprint ID is included in the fingerprint ID. It is determined whether or not the associated data ID exists in the data management table (step 32).
If a data ID exists in this process, the corresponding data is read out from the storage destination (hard disk drive device 14 or the like) and acquired (step S33). Then, the data acquired in step S33 is transmitted from the communication unit 20 to the requesting terminal that has transmitted the data request message (step S34), and the processing here is terminated (step S36).
If there is no matching fingerprint ID in the collation in step 32, or there is no associated data even if there is a matching fingerprint ID, an error is notified to the sender of the data request message. (Step S35), and the process ends (Step S36).

Next, an example of processing when the terminal communication unit 20 receives an operation completion notification (transmitted in step S19 in FIG. 3) from another terminal will be described with reference to the flowchart in FIG.
When the central control unit 11 determines that the communication unit 20 has received the operation completion notification (step S41), the terminal ID (transmission source terminal ID) included in the received operation completion notification is stored as transferable data. The terminal ID of the transfer source terminal is registered in the operation completion state management table (step S42). At this time, the information about the time when the operation completion notification is received by this terminal is also registered. By performing this registration, the process at the time of receiving the operation completion notification is terminated (step S43).

  If the time at which the operation completion notification is received at this terminal is registered in step S42, an operation of counting the elapsed time from the registered time is performed, and a predetermined time (for example, 1 minute) has elapsed. Then, the operation completion notification is discarded from the operation completion state management table. The time for discarding the operation completion notification may be set by a user operation or the like.

  Further, after the transmission in step S34 in the flowchart of FIG. 4, the fingerprint ID registered in the management table in the terminal may be deleted so that the fingerprint ID does not remain. Alternatively, even when a data request message is transmitted, the fingerprint ID added to the data transmission request may be erased from the terminal so that it does not remain.

Next, when the information display terminal 10 to be processed in this way is prepared as shown in FIG. 1 (terminals T10, T11, T12) and arranged to be communicable, the data transfer process is performed. An example will be described with reference to the sequence diagram of FIG.
First, the user U10 touches the portion where the data D10 on the display panel is displayed on the terminal T10 with a finger. As the displayed data D10, for example, phone book data, mail text, images, or file names thereof are assumed (processing 101).
Thereafter, touch transfer selection, touch position acquisition, fingerprint reading, fingerprint ID generation, selection data acquisition, data memory registration, and transfer preparation completion transmission (corresponding to the processing from step S12 to step S19 in the flowchart of FIG. Processes 102, 103, 104, 105, 106, 107, 108) are executed in order. The fingerprint ID registered in the data memory is the fingerprint ID of the user U10.

When there is a transfer preparation completion transmission (step S91) to which the terminal ID of the terminal T10 is added, this transfer preparation completion is received by the terminals T11 and T12 which are neighboring terminals.
Here, it is assumed that the user U10 operating the terminal T10 touches the display panel of the terminal T11 (process 201).
By performing this touch processing, touch position acquisition, fingerprint reading, fingerprint ID generation, and data request transmission (processing 202) corresponding to the processing in steps S12 to S16 and steps S20 and S21 in the flowchart of FIG. , 203, 204, 205) are executed in order.
Transmission of the data request (step S92) is performed from the terminal T11 to the terminal T10, and the fingerprint ID of the user U10 is added.

  When this data request is received by the terminal T10, the fingerprint ID included in the data request and the fingerprint ID registered in the management table are collated, and a match is detected. When a match is detected, the data D10 registered in relation to the fingerprint ID of the user U10 is acquired (process 109), and the data D10 is transmitted with the destination ID of the requesting terminal (process 110). ). By transmitting the data D10 (step S93), the data D10 is received by the terminal T11, and the data D10 is displayed at the position where the touch is detected in the process 201 of the terminal T11 (process 206).

The sequence diagram of FIG. 6 shows a case where data transfer is possible. However, if the fingerprints touched by the two terminals are different, an error state occurs in which data transfer is not performed.
The sequence diagram of FIG. 7 shows an example of this error state. In FIG. 7, the processing until the transfer order completion notification is transmitted in step S91 at the terminal T10 is the same as that in FIG.
In this example, it is assumed that a user U11 different from the user U10 who touched the terminal T10 touches the display panel on the terminal T12 (processing 301).
By performing this touch processing, touch position acquisition, fingerprint reading, fingerprint ID generation, and data request transmission (processing 302) corresponding to steps S12 to S16 and steps S20 and S21 in the flowchart of FIG. , 303, 304, 305) are executed in order. At this time, the fingerprint ID of the user U11 is added to the transmission of the data request from the terminal T12 (step S94).

In the terminal T10 that has received this data request, a mismatch is detected by comparing the fingerprint ID stored in the data management table (the fingerprint ID of the user U10) with the transmitted fingerprint ID (the fingerprint ID of the user U11), The verification fails (process 111), and an error notification transmission process is performed (process 112).
Thus, the error notification is transmitted to the terminal T12 (step S95), and the data D10 is not transferred to the terminal T12 (process 306).
Note that although error processing at the terminal T12 has been described with reference to FIG. 7, even in the case of the terminal T11, an error similarly occurs when the operating user is different from the user who operated the data transmission source terminal T10.

  As described above, according to the present embodiment, as a configuration in which each of a plurality of terminals detects a touched fingerprint, data transfer is performed when the fingerprints detected by the respective terminals are matched. It is possible to transfer data between terminals easily and reliably in a state in which is secured. That is, for example, data transfer is performed only when two terminals are arranged side by side and the display panels of the two terminals are sequentially touched with the same finger of one user, and another user touches with two terminals. In this case, data transfer is not performed, so that no data is transferred by mistake.

  In the case of this example, the selection of data to be transferred and the processing such as the position for displaying received data on the receiving side are also performed by touch processing, so all operations can be performed by touch processing. There is an effect that the operation for data transfer is very simple.

  Also, as shown in the flowchart of FIG. 5, when the operation completion notification is received, the reception time is registered, and the transfer process is invalidated after a certain time has elapsed from the reception time. For example, when touching another terminal after a certain amount of time has passed after touching the transmission source terminal, the data will not be transferred and the user willingly want to transfer the data. Data transfer is performed only when the operation is carried out with this, and also from this point, it is possible to perform reliable data transfer.

  In the case of this example, the data used for fingerprint authentication is used only for detecting a user match between the two terminals and is not used for other processing. There is no possibility of misuse. In particular, by completing the data transfer process, the fingerprint ID stored in each terminal is erased, so that unauthorized use of fingerprint data can be prevented more reliably.

In the above-described embodiment, an example in which the terminal is applied to a mobile phone terminal has been described. However, as long as the terminal has a communication function including a touch panel capable of detecting a fingerprint, various terminals having other configurations. You may apply to.
Alternatively, a personal computer device that performs various data processing is equipped with a board or a card that performs communication processing corresponding to the communication unit of this example, and a panel that performs fingerprint authentication is connected to the personal computer device shown in FIGS. Software (program) for executing the processing shown in the flowchart may be installed in a computer device so that similar data transfer can be performed.

In the above-described embodiment, a terminal that performs data transfer is assumed to be a plurality of terminals arranged close to each other. However, a similar data transfer process may be performed between terminals at remote locations. .
For example, a touch panel of a computer device of a certain user's office is touched when leaving the office, and a home computer device is designated as a transmission destination. Then, when the user returns home, the specified data is transferred from the work computer device to the home computer device by touching the touch panel of the home computer device. In this case, the time information registered in the operation completion state management table shown in the flowchart of FIG. 5 is not a short time such as 1 minute shown in the above example as a valid time, but a time required for movement ( For example, 1 hour or 2 hours) is designated. In this way, it is possible to perform reliable data transfer by specifying a user by fingerprint authentication even between terminals at remote locations.
