  FIG. 2 is a block diagram showing a functional configuration of the information communication terminal device T1 according to the embodiment of the present invention. The information communication terminal device T1 includes a control unit 10. An input unit 20, a storage unit 30, an encryption unit 40, an addition unit 50 and a decryption unit 60 are connected to the control unit 10. In addition, the information communication terminal device T1 includes a transmission unit 70 and a reception unit 80 capable of wireless communication with other terminal devices T2 and T3 located in a preset communication area. A storage unit 90 is connected to the transmission unit 70 and the reception unit 80.

The storage unit 30 stores an own terminal ID assigned to the own terminal device in advance, and supplies the own terminal ID to the control unit 10.
The input unit 20 serves as an interface with the user of the information communication terminal device T1, and includes safety information input by the user, a transmission destination terminal ID of the terminal device specified as the transmission destination, and a transmission source of the terminal device specified as the transmission source. The control unit 10 is supplied with a terminal ID, a decryption key for encrypting safety information transmitted from the terminal itself to the outside, and a reception decryption key for decrypting the safety information from the terminal device designated as the transmission source. Here, the input method in the input unit 20 may be a method of inputting directly by physical means such as buttons and switches, or a method of inputting from the PC connected to the PC. At this time, the connection between the information communication terminal device and the PC may be a connection by a wireless communication method or a connection via the USB by providing the information communication terminal device with a USB module.

  The encryption unit 40 receives the safety information and the decryption key from the control unit 10, encrypts at least a part of the safety information using the decryption key, and supplies the encrypted information to the adding unit 50. The encryption by the encryption unit 40 may use a data compression method such as Zip with a password, or a public key encryption method such as RSA or a secret key encryption method such as FEAL (Fast data Encipherment Algorithm). It may be used.

The adding unit 50 adds the own terminal ID and the transmission destination terminal ID supplied from the control unit 10 to the safety information encrypted by the encryption unit 40. Here, each terminal ID is added as From and To, for example, in the header portion of the safety information.
The receiving unit 80 automatically receives safety information transmitted from another terminal device located in the communication area using a wireless communication method.
The accumulation unit 90 accumulates the safety information supplied from the adding unit 50 and the safety information received by the receiving unit 80.
The transmission unit 70 automatically transmits the safety information stored in the storage unit 90 to other terminal devices located in the communication area using a wireless communication method. As a wireless communication method in the transmission unit 70 and the reception unit 80, for example, a wireless LAN method such as Wi-Fi (registered trademark), infrared communication, Bluetooth (registered trademark), or the like is used.

  The decryption unit 60 receives the transmission source terminal ID and the reception decryption key from the control unit 10, and determines whether the own terminal ID added to the received safety information matches the registered transmission source terminal ID, If they match, decrypt using the received decryption key. In addition, the decoding unit 60 receives the own terminal ID from the control unit 10 and determines whether or not the destination terminal ID added to the decrypted safety information matches the own terminal ID. Safety information is supplied to the output unit 100. If the safety information is not encrypted, the safety information is supplied to the output unit 100 without performing the decryption process after determining the transmission destination terminal ID.

The output unit 100 outputs the safety information from the decoding unit 60 to the outside using, for example, a display screen such as a liquid crystal screen visible to the user.
The control unit 10 includes a CPU (Central Processing Unit) made of, for example, a microprocessor, and is configured as follows. That is, the control unit 10 includes a main control unit 11, a key registration unit 12, and a terminal ID registration unit 13. Among these, the functions of the main control unit 11, the key registration unit 12, and the terminal ID registration unit 13 are realized by causing the CPU to execute an application program. This application program can be obtained, for example, by taking in a recording medium on which this application program is recorded.

  The main control unit 11 comprehensively controls the operation of the information communication terminal device T1. When receiving the decryption key and the received decryption key from the input unit 20, the main control unit 11 supplies these keys to the key registration unit 12. Further, when receiving the transmission destination terminal ID and the transmission source terminal ID from the input unit 20, the main control unit 11 supplies these terminal IDs to the terminal ID registration unit 13. Further, when receiving the safety information of the own terminal from the input unit 20, the main control unit 11 supplies this safety information to the encryption unit 40. The main control unit 11 reads the own terminal ID from the storage unit 30 and supplies the own terminal ID to the adding unit 50 and the decoding unit 60.

The key registration unit 12 receives the decryption key and the reception decryption key from the main control unit 11, and registers these keys. Further, the key registration unit 12 supplies the decryption key to the encryption unit 40 and supplies the reception decryption key to the decryption unit 60 according to the instruction of the main control unit 11.
The terminal ID registration unit 13 receives the transmission destination terminal ID and the transmission source terminal ID from the main control unit 11 and registers these terminal IDs. Further, the terminal ID registration unit 13 supplies the transmission destination terminal ID to the adding unit 50 and the decoding unit 60 and supplies the transmission source terminal ID to the decoding unit 60 according to an instruction from the main control unit 11.

  Hereinafter, the safety information transmission process in the information communication terminal device having the above-described configuration will be described in detail. In the following example, it is assumed that each individual terminal is always carried by each individual. However, by registering the family as safety information to be registered, the terminal can be used as one terminal for a family. it can.

  FIG. 3 is a schematic diagram showing a configuration example of a safety information transmission system according to an embodiment of the present invention. Here, an example will be described in which the information communication terminal device is used by a family composed of three persons, a father, a mother, and a child. In FIG. 3, the information communication terminal device used by the father is the terminal device TF, the information communication terminal device used by the mother is the terminal device TM, and the information communication terminal device used by the child is the terminal device TC. T6 to Tn are other terminal devices located around the terminal devices TF, TM, and TC.

  FIG. 4 is a flowchart showing a pre-setting process of the main control unit 11 according to an embodiment of the present invention. Each terminal device TF, TM, TC is preset so that safety information from each terminal device can be acquired. FIG. 5 shows an output example after the prior setting of the main control unit 11 according to an embodiment of the present invention. In FIG. 5, in addition to information on the transmission destination terminal ID and transmission source terminal ID set in the local terminal device, items about safety information are also described. This description part is changed after receiving the safety information.

  First, a user of each terminal device TF, TM, TC inputs a decryption key for decrypting safety information input by the terminal device TF, TM, TC to the input unit 20. The main control unit 11 registers this decryption key in the key registration unit 12 (step 4a). At this time, the decryption key “autosan” is registered in the terminal device TF, the decryption key “okasan” is registered in the terminal device TM, and the decryption key “kodomo” is registered in the terminal device TC.

  Next, the user inputs the transmission destination terminal ID into the input unit 20. The main control unit 11 registers this destination terminal ID in the terminal ID registration unit 13 (step 4b). At this time, the terminal IDs “0000000002” and “00000000003” of the mother and child are registered in the terminal device TF, the terminal IDs “0000000001” and “00000000003” of the father and child are registered in the terminal device TM, and the father ID is registered in the terminal device TC. Mother terminal IDs “0000000001” and “00000000002” are registered.

  Subsequently, the user inputs the transmission source terminal ID into the input unit 20. The main control unit 11 registers this transmission source terminal ID in the terminal ID registration unit 13. At this time, the terminal IDs “0000000002” and “00000000003” of the mother and child are registered in the terminal device TF, the terminal IDs “0000000001” and “00000000003” of the father and child are registered in the terminal device TM, and the father ID is registered in the terminal device TC. Mother terminal IDs “0000000001” and “00000000002” are registered.

  Subsequently, the user inputs a reception decryption key for decrypting the safety information from the terminal device desired to be received into the input unit 20. The main control unit 11 registers the received decryption key in the key registration unit 12 (step 4d) and ends the process. At this time, the decryption keys “okasan” and “kodomo” for the mother and the child are registered as reception decryption keys in the terminal device TF, and the decryption keys “otousan” and “kodomo” for the father and child are registered as the reception decryption keys in the terminal device TM. The terminal device TC registers the decryption keys “otousan” and “okasan” of the father and mother as reception decryption keys.

  Note that the encryption by the encryption unit 40 and the decryption by the decryption unit 60 are a pair of processes, so that the decryption key for encryption and the reception decryption key for decryption must correspond to each other. There is. That is, it is necessary to associate the decryption key and the reception decryption key in advance between the user on the transmission side and the user on the reception side. In this embodiment, since it is a family of parents and children, it is assumed that the decryption key is heard in advance and is input.

  In the example of the presetting, a 10-digit number is used as the terminal ID. However, the terminal device is not limited to this as long as the terminal device can be uniquely identified. In addition, although alphabetic characters are displayed as decryption keys, they may be concealed with characters such as “* (asterisk)”.

FIG. 6 is a flowchart showing processing at the time of safety information input of the main control unit 11 according to an embodiment of the present invention.
First, the main control unit 11 determines whether or not the decryption key has been registered in the key registration unit 12 (step 6a). If it has been registered (Yes in step 6a), the process proceeds to step 6b. If it has not been registered (No in Step 6a), the input of the decryption key is requested, and the input decryption key is registered in the key registration unit 12 (Step 6c).

  When a disaster occurs, the user of the terminal device inputs his / her safety information to the terminal device. In step 6b, the main control unit 11 determines whether or not safety information is input. If there is an input, the main control unit 11 encrypts the safety information and the decryption key registered in the key registration unit 12 in step 6d. To supply. Subsequently, the main control unit 11 supplies the terminal unit ID and the transmission destination terminal ID registered in the terminal ID registration unit 13 to the adding unit 50 (step 6e). Next, the main control unit 11 determines whether the safety information output from the adding unit 50 has been accumulated in the accumulation unit 90 (step 6f). When safety information is accumulated in the accumulating unit 90 (Yes in Step 6f), the transmitting unit 70 and the receiving unit 80 are set in a state of waiting for communication from another terminal device (Step 6g), and the process is terminated.

FIG. 7 is a diagram illustrating an example of an input screen when safety information is input from the input unit 20 according to an embodiment of the present invention.
In FIG. 7, necessary information is classified into safety information to be input, and each item has a selection formula. Here, among the contents of the safety information, “A) Safety state” is not encrypted, and the terminal device that has received the safety information has registered the decryption key of the terminal device that has transmitted the safety information as the reception decryption key. It is set to display the contents at least. On the other hand, “B) registration location” and “C) future destination” are encrypted, and are set so that the contents cannot be displayed unless the received terminal device has registered the reception decryption key. As a result, among safety information, safety information with low confidentiality and high urgency can be displayed on all received terminal devices, and safety information with high confidentiality can be displayed only on specific terminal devices. It becomes possible to do.

  Further, by unifying the items in the safety information into the items shown in FIG. 7, it is only necessary to input and transmit only the symbol such as “AlB3C1” as the safety information, so that “safety state: safe. No injury, registration place: Information such as “company / school, future destination: home” can be notified, so the amount of data can be reduced. In addition, even if this safety information is received by another terminal device, if the terminal in the safety information is not unified, the safety information of only the symbol will be received, and the safety of the individual without encryption. It becomes possible to suppress the outflow of information.

In the example of FIG. 7, safety information is divided into items, and each item is input by a selection formula. However, safety information may be input by a free sentence.
FIG. 8 is a flowchart showing processing at the time of safety information communication of the information communication terminal device according to the embodiment of the present invention. In FIG. 8, the flow of its own terminal device is shown on the left side, and the flow of another terminal device is shown on the right side for comparison with the self terminal device.
The main control unit 11 in the own terminal device determines whether there is another terminal device that can communicate within the communication area of the own terminal device (step 8a). When another terminal device is located in the communication area (Yes in Step 8a), the main control unit 11 establishes a network with the other terminal device (Step 8b). When the network is established, the self-terminal device automatically transmits all the safety information stored in the storage unit 90 to other terminal devices (step 8c). In addition, the own terminal device automatically receives the safety information transmitted from the other terminal devices and stores it in the storage unit 90 (step 8d). Then, when the transmission / reception of the safety information with the other terminal devices is completed, the own terminal device disconnects the network (step 8e) and ends the process.

FIG. 9 is a flowchart showing processing after the safety information is received by the main control unit 11 according to an embodiment of the present invention.
When the safety information received by the receiving unit 80 is stored in the storage unit 90, the main control unit 11 supplies the source terminal ID registered in the terminal ID registration unit 13 to the decoding unit 60 (step 9a). The main control unit 11 determines whether or not the own terminal ID added to the safety information matches the transmission source terminal ID registered in advance (step 9b). If they match (Yes in step 9b), the received decryption key registered in the key registration unit 12 is supplied to the decryption unit 60 (step 9c). The main control unit 11 determines whether or not the stored safety information can be decrypted with the received decryption key registered in advance (step 9d). If the decryption is possible (Yes in step 9d), the safety information is decrypted using the received decryption key (step 9e).

  Subsequently, the main control unit 11 supplies the own terminal ID to the decoding unit 60 (step 9f), and determines whether or not the transmission destination terminal ID added to the safety information matches the own terminal ID (step 9g). ). If they match (Yes in step 9g), the safety information is supplied to the output unit 100 (step 9h), and the process is terminated.

In step 9d, the main control unit 11 terminates the process if it cannot be decrypted with the reception decryption key registered in advance. Moreover, the main control part 11 complete | finishes a process, when the transmission destination terminal ID added to the safety information does not correspond with own terminal ID in step 9g.
FIG. 10 is a diagram showing an example in which the safety information input to the terminal device TM is transmitted to the terminal device TF via the other terminal devices T6 to Tn in the safety information transmission system shown in FIG. Here, the safety information of the “mother” who is the user of the terminal device TM is “Info_M”, and the safety information of the other terminal devices T6 to Tn is all expressed as “Info_NN”.

  First, when the terminal device T6 enters the communication area of the terminal device TM, the terminal device TM transmits safety information “Info_M” stored in the storage unit 90 to the terminal device T6. Similarly, the safety information “Info_NN” held by the terminal device T6 is transmitted to the terminal device TM (not shown).

  Next, the terminal device T6 transmits the safety information “Info_NN” and “Info_M” held by the terminal device T6 to the terminal device T7 in the communication area of the terminal device T6. However, the arrow for transmitting the safety information “Info_NN” held by the terminal device T6 to the terminal device T7 is not shown. In this way, the safety information “Info_M” is transmitted by communication between adjacent terminal devices, and is transmitted to the terminal device TF via the terminal devices T6, T7... Tn. The terminal device TF has received the terminal ID “0000000002” of the terminal device TM as a transmission source terminal in advance and the decryption key “okasan” of the terminal device TM has been registered as a reception decryption key in advance. “Info_M” can be decoded.

In addition, since the safety information in each terminal device is copied and transmitted in each terminal device, it is continuously stored in the terminal device.
Further, since the terminal ID added as From or To in the header portion of the safety information is held in the storage unit 90 as it is, information that matches From and To is not received. The device can prevent double reception of safety information.

  When the destination terminal ID added to the received safety information is only the own terminal ID, the information communication terminal device ends the transmission of the safety information at the own terminal device. In addition, when the destination terminal ID added to the received safety information includes other than the own terminal ID, the information communication terminal device deletes the added own terminal ID, and then transmits this safety information between the terminal devices. The data is again stored in the storage unit 90 as an exchange target.

  FIG. 11 shows a presentation example of the received safety information. Moreover, the example of a presentation in the output screen of the terminal device TF at this time is shown in FIG. It should be noted that “AlB3C1” described in the detail column of the own terminal safety information in FIG. 12 is a symbolization of the safety information input by the own terminal device. The number of cases displayed in the stored safety information column is the number of safety information transmitted from other terminal devices held by the terminal device. As for the safety information from the terminal ID that has not been registered as the reception source in advance, neither the terminal ID itself nor the contents of the safety information are displayed.

  Moreover, in the example of the output screen presented in the above embodiment, the time information is not described, but the time information can be attached to the safety information by providing the terminal device with a clock function. By attaching the time information, when the safety information once input is updated, it is possible to determine which safety information is the latest when receiving the two safety information.

  As described above, the terminal device TM in the above embodiment registers the terminal IDs of the terminal devices TF and TC in advance as the transmission destination terminal ID and the transmission source terminal ID, and the decryption key of the terminal device and the terminal devices TF and TC The receiving decryption key is registered in advance. Then, the terminal device TM adds its own terminal ID and the destination terminal ID, encrypts it with the decryption key, and then automatically transmits the safety information to other terminal devices in the vicinity. The safety information automatically transmitted from the terminal device TM is transmitted from another terminal device close to the terminal device to another terminal device close to the terminal device, and is transmitted to the terminal device TF via some terminal devices. The Also, the terminal device TF automatically receives safety information from other nearby terminals, decrypts it using the reception decryption key registered in the decryption unit 60, and outputs it to the father. At this time, the decoding unit 60 determines whether or not the own terminal ID added to the received safety information matches the terminal ID of the terminal device TM that is the registered transmission source terminal ID. The safety information is decrypted with the reception decryption key for the device TM. Then, the decrypting unit 60 determines whether or not the transmission destination terminal ID added to the decrypted safety information matches the own terminal ID, and if it matches, supplies the safety information to the output unit 100. .

  That is, the information communication terminal device can transmit the safety information to a terminal device used by a family or an acquaintance registered in advance while communicating between the terminal devices without going through the network. That is, safety information can be smoothly transmitted even when the network is congested during a disaster or the like.

  In addition, the information communication terminal device can transmit safety information to a previously designated terminal device via another terminal device, and can obtain safety information from the designated terminal device. That is, since the safety information is not accumulated in the server device or the like, the user can obtain the safety information without making an inquiry to the server device or the like.

  Further, the information communication terminal device can display the safety information only by the designated terminal device by designating and encrypting the transmission destination of the safety information. That is, it is possible to prevent browsing of the safety information of the other party who does not want to notify his / her safety information, and personal information called safety information can be protected.

  Therefore, the information communication terminal device, the safety information transmission method, the program for executing the processing of the information communication terminal device and the recording medium storing the program according to the present invention are congested in the existing network at the time of disaster, etc. Even in the state, it is not necessary for the user to actively check the safety information, and the safety information can be transmitted only to the other party desired by the user.

  The present invention is not limited to the above-described embodiment. For example, in the above-described embodiment, the example in which the safety information is acquired based on the terminal ID registered in advance has been described. However, the present invention is not limited to the prior registration. For example, when the terminal ID is registered when the safety information is input. But it can be done in the same way.

  Further, in the above-described embodiment, the example in which the safety information with the terminal ID added is stored in the storage unit 90. However, the information communication terminal device can perform position measurement such as GPS (Global Positioning System). And position information may be acquired at a place where safety information is input, and the safety information may be stored in the storage unit 90 together with the position information.

  Furthermore, the present invention can be embodied by modifying the constituent elements without departing from the spirit of the invention in the implementation stage. In addition, various inventions can be formed by appropriately combining a plurality of components disclosed in the embodiment. For example, some components may be deleted from all the components shown in the embodiment.
