Description

  The present invention relates to a data terminal device, and more particularly to a data terminal device that deletes transmission data after a transmission operation.

A conventional data transmission system will be described with reference to FIG.
In FIG. 1, the data terminal device 10 includes an application 11 and a data transmission unit 12. The data terminal device 10 transmits and receives data using a network. The application 11 handles data such as a WEB browser and a mail client. The data transmission unit 12 transmits the transmission data received from the application 11 to the network 100.

However, the conventional data transmission system has the following problems.
The first problem is that the transmission data cannot be deleted after the data transmission operation in the application 11 because the transmission data is transmitted immediately. Therefore, even if there is an error in the transmission destination or transmission content, the transmission data cannot be deleted after the data transmission operation.
The second problem is that since transmission data is not monitored, when an application such as a virus tries to transmit data regardless of the intention of the data terminal operator (user), transmission cannot be stopped. It is. For example, when a virus attached to an email is executed as an application without noticing it as a virus, the virus transmits malicious data without notifying the data terminal operator of data transmission. On the other hand, the data terminal operator cannot delete the malicious data transmitted by the virus even if the data terminal operator becomes suspicious due to the situation where there is no change after the program is executed.

  The program of the present invention causes a computer to execute the above transmission data deleting method.

  Since the data terminal device has a transmission data buffer and a means for deleting data on the buffer, the data terminal operator (user) can delete the transmission data after the data transmission operation.

A first embodiment of the present invention will be described below with reference to the accompanying drawings.
Referring to FIG. 2, the data terminal device 10 includes an application 11, a data transmission unit 12, a transmission data buffer 13, and a transmission data buffer management unit 14.

  The data terminal device 10 transmits and receives data using the network 100. The application 11 handles data such as a WEB browser and a mail client. Since the application is normally executed by a processing device such as a CPU, the application 11 includes a processing unit for executing the application. The transmission data buffer 13 buffers transmission data that the application 11 sends to the data transmission unit 12 in order to transmit data to the network. The transmission data buffer management unit 14 manages the time for which transmission data is buffered in the transmission data buffer 13, and the transmission data in the transmission data buffer 13 is requested by a data terminal operator (user) in the transmission data buffer. Delete. The data transmission unit 12 transmits the data received from the transmission data buffer 13 to the network 100, but the data deleted by the transmission data buffer management unit 14 is not passed to the data transmission unit 12, so the data is transmitted to the network 100. It will never be done. In this way, in the present invention, the data transmission after the data transmission operation is stopped by the application 11 by buffering and deleting the transmission data.

These generally operate as follows.
The application 11 passes transmission data to be passed to a server on the network 100 to the transmission data buffer 13.

  The transmission data buffer 13 buffers the transmission data received from the application 11 and passes the transmission data to the data transmission unit 12 according to an instruction from the transmission data buffer management unit 14.

  Referring to FIG. 3, the transmission data buffer management unit 14 includes a buffer time management unit 141, a transmission data deletion unit 142, and a transmission data deletion reception unit 143. The transmission data buffer management unit 14 is connected to the transmission stop switch 20.

  The buffer time management unit 141 manages the time during which transmission data is buffered in the transmission data buffer 13, and after the transmission data is buffered in the transmission data buffer 13, when a preset time has elapsed, the transmission data buffer 13 To send data.

  The transmission data deletion unit 142 deletes the transmission data buffered in the data transmission buffer 3 when a transmission data deletion request is received from the transmission data deletion reception unit 143 within the time set in the buffer time management unit 141.

  The transmission stop switch 20 is connected to the data terminal device 10 and transmits a transmission data deletion request from the data terminal operator to the transmission data deletion reception unit 143. The transmission stop switch 20 is not limited to a physical switch that is actually provided in the casing or input device of the data terminal device 10, but is a virtual button such as a button displayed on the display screen of the data terminal device 10. A switch may be used. It is possible to use both physical switches and virtual switches.

  The data transmission unit 12 transmits the data received from the transmission data buffer 13 to the network. However, the data deleted by the transmission data buffer management unit 14 is not passed to the data transmission unit 12, and therefore the data is not transmitted to the network.

Next, the overall operation of this embodiment will be described in detail with reference to FIG.
(1) Step S101
The application 11 transmits / receives data to / from a server on the network, and processes a request from the data terminal operator. Here, transmission data is passed to the transmission data buffer 13 in order to transmit data to the server.
(2) Step S102
The transmission data buffer 13 buffers the transmission data received from the application 11 and holds it until there is an instruction from the transmission data buffer management unit 14.
(3) Step S103
When the buffer time management unit 141 recognizes that the transmission data is buffered in the transmission data buffer 13, the buffer time management unit 141 starts counting the buffer time.
(4) Step S104
Until the count of the buffer time management unit 141 reaches a preset time, the buffer time management unit 141 monitors the transmission data deletion reception unit 143 for a transmission data deletion request. Here, since the transmission data deletion request is generated when the transmission stop switch 20 is operated, the operation on the transmission stop switch 20 may be monitored.
(5) Step S105
If there is no transmission data deletion request in the transmission data deletion reception unit 143 before the count of the buffer time management unit 141 reaches a preset time, the buffer time management unit 141 transmits data to the transmission data buffer 13. The instructions are given. Upon receiving the instruction, the transmission data buffer 13 passes the transmission data to the data transmission unit 12. The data transmission unit 12 transmits the received transmission data to the network 100 so that the transmission data is transferred to a server on the network 100.
(6) Step S106
On the other hand, if the data terminal operator operates the transmission stop switch 20 before the count of the buffer time management unit 141 reaches a preset time, the transmission data deletion reception unit 143 receives a transmission data deletion request. The transmission data deletion unit 142 is instructed to delete transmission data. The transmission data deletion unit 142 deletes transmission data in the transmission data buffer 13 according to an instruction from the transmission data deletion reception unit 143. In this case, since transmission data is not passed to the data transmission unit 12, transmission data is not sent over the network.

  Actually, transmission data may be buffered in the transmission data buffer 13 until a data transmission request is received again from the data terminal operator without counting by the buffer time management unit 141. In other words, it is necessary to obtain permission from the data terminal operator when transmitting data. In this case, transmission data can be deleted until a data transmission request is received again.

  The transmission data buffer 13 is not limited to the data terminal device 10 but may exist in a server on the network 100. For example, when transmission data is an electronic mail, it is known that transmission data is once stored in a mail server. The transmission data buffer 13 in the mail server holds the transmission data until an instruction from the transmission data buffer management unit 14 is received. Furthermore, by combining with the transmission data buffer 13 in the data terminal device 10, the opportunity to delete the transmission data after the data transmission operation can be increased. At this time, the buffer time management unit 141 separately performs the count for the transmission data buffer 13 in the data terminal device 10 and the count for the transmission data buffer 13 in the server. Each count may be notified to the data terminal operator via the data terminal device 10.

The second embodiment of the present invention will be described below.
The basic configuration of the second embodiment of the present invention is as described above, but the transmission data deletion request means is further devised. The configuration is shown in FIG.

  As shown in FIG. 5, in this embodiment, the voice input device 30 is used instead of the transmission stop switch 20, and the voice input recognition unit 15 for recognizing the voice input from the voice input device 30 is provided in the data terminal device 10. Provided. That is, in the present embodiment, the data terminal device 10 includes an application 11, a data transmission unit 12, a transmission data buffer 13, a transmission data buffer management unit 14, and a voice input recognition unit 15. The voice input recognition unit 15 is provided between the transmission data buffer management unit 14 and the voice input device 30.

Next, the overall operation of this embodiment will be described in detail with reference to FIG.
(1) Step S201
The application 11 passes transmission data to the transmission data buffer 13 in order to transmit data to the server.
(2) Step S202
The transmission data buffer 13 buffers the transmission data received from the application 11 and holds it until there is an instruction from the transmission data buffer management unit 14.
(3) Step S203
When the buffer time management unit 141 recognizes that the transmission data is buffered in the transmission data buffer 13, the buffer time management unit 141 starts counting the buffer time.
(4) Step S204
Until the count of the buffer time management unit 141 reaches a preset time, the buffer time management unit 141 monitors the transmission data deletion reception unit 143 for a transmission data deletion request. Here, when the data terminal operator wants to delete the transmission data, he / she utters the voice to the voice input device 30 and transmits if the voice input recognition unit 15 determines that the voice is valid voice. The voice data deletion request is transmitted to the data deletion receiving unit 143.
(5) Step S205
If there is no transmission data deletion request in the transmission data deletion reception unit 143 before the count of the buffer time management unit 141 reaches a preset time, the transmission data buffer 13 is instructed to transmit data. Upon receiving the instruction, the transmission data buffer 13 passes the transmission data to the data transmission unit 12. The data transmission unit 12 transmits the received transmission data to the network 100 so that the transmission data is transferred to a server on the network 100.
(6) Step S206
On the other hand, when the voice data deletion request is transmitted to the transmission data deletion reception unit 143 before the count of the buffer time management unit 141 reaches the preset time, the transmission data deletion reception unit 143 issues a transmission data deletion request. Accept and instruct the transmission data deletion unit 142 to delete transmission data. The transmission data deletion unit 142 deletes transmission data in the transmission data buffer 13 according to an instruction from the transmission data deletion reception unit 143. In this case, since transmission data is not passed to the data transmission unit 12, the transmission data is not sent over the network.

  As described above, since the transmission data deletion request can be made by voice in this embodiment, there is an effect that transmission data can be deleted even in an emergency without searching for a transmission stop switch.

The third embodiment of the present invention will be described below.
In the present embodiment, as shown in FIG. 7, an input device 40 such as a keyboard or a mouse may be used instead of the voice input device 30, and an abnormal input detection unit 16 may be used instead of the voice input recognition unit 15. That is, in this embodiment, the data terminal device 10 includes an application 11, a data transmission unit 12, a transmission data buffer 13, a transmission data buffer management unit 14, and an abnormal input detection unit 16. The abnormal input detection unit 16 is provided between the transmission data buffer management unit 14 and the input device 40 and detects an abnormal operation or input performed on the input device 40. When an abnormal operation or input is detected, a transmission data deletion request is transmitted to the transmission data deletion reception unit 143. Note that an abnormal operation or input is an operation or input that is not assumed or is unlikely to be performed in a normal data transmission operation. At this time, a predetermined operation or input may be defined in advance as an abnormal operation or input.

  For example, when the input device 40 is a keyboard, the abnormal input detection unit 16 determines that it is a transmission data deletion request by randomly pressing a plurality of keys from the keyboard (such as hitting the keyboard in a panic state), and the transmission data deletion request Is transmitted to the transmission data deletion accepting unit 143.

  When the input device 40 is a mouse, the abnormal input detection unit 16 determines that it is a transmission data deletion request by operating the mouse left and right at high speed, and transmits the transmission data deletion request to the transmission data deletion reception unit 143. To do.

Next, the overall operation of this embodiment will be described in detail with reference to FIG.
(1) Step S301
The application 11 passes transmission data to the transmission data buffer 13 in order to transmit data to the server.
(2) Step S302
The transmission data buffer 13 buffers the transmission data received from the application 11 and holds it until there is an instruction from the transmission data buffer management unit 14.
(3) Step S303
When the buffer time management unit 141 recognizes that the transmission data is buffered in the transmission data buffer 13, the buffer time management unit 141 starts counting the buffer time.
(4) Step S304
Until the count of the buffer time management unit 141 reaches a preset time, the buffer time management unit 141 monitors the transmission data deletion reception unit 143 for a transmission data deletion request. Here, when the abnormal input detection unit 16 detects an abnormal operation or input performed on the input device 40, the abnormal input detection unit 16 transmits a voice data deletion request to the transmission data deletion reception unit 143. The output from the abnormal input detection unit 16 may be monitored.
(5) Step S305
If there is no transmission data deletion request in the transmission data deletion reception unit 143 before the count of the buffer time management unit 141 reaches a preset time, the buffer time management unit 141 transmits data to the transmission data buffer 13. The instructions are given. Upon receiving the instruction, the transmission data buffer 13 passes the transmission data to the data transmission unit 12. The data transmission unit 12 transmits the received transmission data to the network 100 so that the transmission data is transferred to a server on the network 100.
(6) Step S306
On the other hand, if the abnormal input detection unit 16 detects an abnormal operation or input performed on the input device 40 before the count of the buffer time management unit 141 reaches a preset time, the transmission data is deleted. The reception unit 143 receives a transmission data deletion request from the abnormal input detection unit 16 and instructs the transmission data deletion unit 142 to delete transmission data. The transmission data deletion unit 142 deletes transmission data in the transmission data buffer 13 according to an instruction from the transmission data deletion reception unit 143. In this case, since transmission data is not passed to the data transmission unit 12, transmission data is not sent over the network.

  In addition, it is also possible to combine and implement each embodiment described so far. The embodiments do not compete with each other. At this time, the transmission data deletion reception unit 143 instructs the transmission data deletion unit 142 to delete transmission data based on the transmission data deletion request received first. By combining in this way, when it is desired to delete transmission data in a hurry, a transmission data deletion request can be transmitted based on the first one of the operations performed by the data terminal operator. Further, for example, when a voice cannot be produced or when a keyboard or a mouse cannot be used, a transmission data deletion request can be transmitted by selecting an optimum means according to the situation at that time.

  Further, when the transmission data in the transmission data buffer 13 is deleted in response to the transmission data deletion request, an application or a program related to the transmission data may be stopped at the same time. For example, when data is transmitted by a virus or the like, an application or program may be forcibly activated. In this way, it is possible to eliminate the trouble of individually stopping these applications and programs after deleting transmission data. Also, by stopping these applications and programs, unexpected damage and secondary damage can be prevented.

Finally, the features of the present invention will be described in detail.
A data terminal device according to the present invention is a data terminal device including an application that transmits / receives data to / from a server on a network and a data transmission unit that transmits transmission data of the application to the network. A transmission data buffer for buffering transmission data and a transmission data buffer management unit for deleting transmission data in the transmission data buffer are included. At this time, the transmission data buffer management unit includes a buffer time management unit, a transmission data deletion unit, and a transmission data deletion reception unit. The transmission data deletion accepting unit accepts a transmission data deletion request by the transmission stop switch. Alternatively, the transmission data deletion receiving unit receives a transmission data deletion request from the voice input device and the voice input recognition unit. Alternatively, the transmission data deletion reception unit receives a transmission data deletion request from the keyboard and the abnormal input detection unit. Alternatively, the transmission data deletion reception unit receives a transmission data deletion request from the mouse and the abnormal input detection unit.

  As described above, the present invention is characterized in that the data terminal device realizes the data transmission stop after the data transmission operation.
