FIG. 2 is a diagram showing an example of the content of the privacy level PL given by the level giving unit 22 of the communication device 20 and the communication method selected by the communication unit 24. First, in this embodiment, the privacy level PL given by the level giving unit 22 corresponds to the disclosure level (disclosure allowable range) of the passenger information D1.

For example, in this embodiment, the privacy level PL given by the level giving unit 22 is information that the passenger information D1 may be disclosed to an unspecified number of people or information that should be disclosed only to a specific partner. It is determined based on whether the information is or should not be disclosed. The communication unit 24 transmits the passenger information D1 together with the privacy level PL at the security level based on this classification standard.

Specifically, the level assigning unit 22 assigns a level (first level) L1 to which an unspecified number of communication devices are to be transmitted to the passenger information D1 which may be disclosed to an unspecified number of people. To do. The communication unit 24 transmits the passenger information D1 of the level L1 by using a communication method corresponding to the broadcast transmission.

Next, the level assigning unit 22 assigns a level (second level) L2 or L3 to which only the specific communication device is to be transmitted to the passenger information D1 that should be disclosed only to the specific partner. .. In this embodiment, when targeting a specific communication device, the level assigning unit 22 assigns level L2 or level L3 corresponding to a communication method having a security level higher than level L2.

The communication unit 24 transmits the passenger information D1 of the level L2 by using a communication method for transmitting the passenger information D1 to each communication device. Further, the communication unit 24 designates an individual communication device for the passenger information D1 of the level L3, and transmits the passenger information D1 by using a communication method that requires authentication.

For example, as a communication method for transmitting the passenger information D1 of the privacy level PL of the level L1, the device ID of Wi-Fi Direct (registered trademark) includes the passenger information D1 in an array commonly set in the system. There is a method of transmitting to the outside. Further, as a communication method for transmitting the level L2 passenger information D1, the device ID of Wi-Fi Direct (registered trademark) includes the passenger information D1 in an array set only with a specific communication device. There is a method of transmitting without.

In addition, as a communication method for transmitting level L3 passenger information D1, communication authentication (establishment of normal one-to-one communication) is performed with a specific communication device using Wi-Fi Direct (registered trademark). Then, a method of transmitting the passenger information D1 can be mentioned.

Further, as shown in FIG. 2, the level assigning unit 22 sets a secret level (third level) L4, that is, a level that is not to be transmitted, for the passenger information D1 that should not be disclosed. Give. In this embodiment, the communication unit 24 does not transmit the passenger information D1 to the outside even when the passenger information D1 of the level L4 is selected. In other words, in this embodiment, the communication unit 24 transmits only the passenger information D1 to which the privacy level PL of the level L1 to L3 (level L3 or lower) is given.

The level giving unit 22 may give the level of the passenger information D1 using a predetermined table, or may give the level by operating the UI unit 25 from the user. Further, the communication unit 24 may accept the user to select the communication method of the UI unit 25 when transmitting the passenger information D1 (transmission information D3), and may adopt the selected communication method.

Further, the UI unit 25 may be configured to display (output) so that the communication method below the level assigned to the passenger information D1 cannot be selected at the time of accepting the selection of the communication method. This prevents, for example, the passenger information D1 having a high privacy level PL from being accidentally broadcasted by a low security communication method while the vehicle is driving.

FIG. 3 is a diagram showing a flow for imparting a privacy level to the passenger information D1 by the communication device 20. The communication device 20 starts the operation by acquiring the passenger information D1 which is the information about the passenger of the mobile body V1 (step S11). For example, the information acquisition unit 21 of the communication device 20 acquires the passenger information D1 from the electronic devices T1 or T2 of the passengers boarding the mobile body V1. Further, for example, the information acquisition unit 21 acquires data including a plurality of information as passenger information D1.

Next, the level giving unit 22 analyzes the passenger information D1 and determines the privacy level PL of the passenger information D1 (step S12). For example, when a plurality of passenger information D1s are acquired, the privacy level PL is determined for each of the plurality of passenger information D1s.

Subsequently, the level giving unit 22 gives (sets) the determined privacy level PL to the passenger information D1 (step S13). Specifically, the level giving unit 22 generates the leveled information D2 including each of the passenger information D1 to which the privacy level PL is given.

FIG. 4A is a diagram showing an example of a determination table used by the level assigning unit 22 to determine the privacy level PL of the passenger information D1. For example, the level giving unit 22 determines the privacy level PL for each of the passenger information D1 based on the table as shown in FIG. 4A. For example, when vehicle information such as the type (information D1 (1)) and color (information D1 (2)) of the vehicle as the moving body V1 is acquired, the information is of level L1 which is a relatively low privacy level PL. Judge as information. On the other hand, when personal information such as the passenger's My Number (information D1 (15)) is acquired, it is determined that the information is level L4 information which is a relatively high privacy level PL.

FIG. 4B is a diagram showing a detailed example of the leveled information D2 in which the level assigning unit 22 assigns the privacy level PL to the passenger information D1. Note that FIG. 4B is a diagram showing an example in which the level assigning unit 22 assigns the privacy level PL based on the level determination table shown in FIG. 4A.

Specifically, for example, the passenger information D1 acquired by the information acquisition unit 21 includes vehicle information (items 1 to 3), its position information (item 4), and the age and gender of the passenger (items 5 to 10). And group composition (item 11) and the like may be included. Further, as shown in FIG. 4B, the passenger information D1 includes the passenger's future travel schedule (information on the destination and its purpose, items 13 to 15) and the passenger's personal data (items 16 to 16 to). 18) and the like may be included.

For example, the level giving unit 22 can give the privacy level PL of level L1 to the vehicle information and the position information. In addition, the level giving unit 22 can give a privacy level PL of level L2 to information such as the age, gender, and group composition of passengers that cannot identify an individual.

Further, the level giving unit 22 can give a privacy level PL of level L3, which is a relatively high privacy level, for the future schedule of the passenger, for example. In addition, the level giving unit 22 can give the highest level L4 privacy level PL to personal information such as the passenger's My Number. It should be noted that the level determination and granting criteria of the level granting unit 22 are only an example.

Referring to FIG. 3 again, the level giving unit 22 then supplies the leveled information D2 to the storage unit 23. The storage unit 23 stores the leveled information D2 (step S14). After that, the communication device 20 ends the privacy level PL grant flow and waits until new passenger information D1 is acquired. In this way, the communication device 20 imparts the privacy level PL of the passenger information D1.

FIG. 5 is a diagram showing a transmission flow of passenger information D1 (information with level D2) by the communication device 20. In this embodiment, the communication device 20 starts the information transmission operation when the UI unit 25 receives the transmission request of the passenger information D1. First, the UI unit 25 receives an information transmission request from the user, and receives the selection of the transmission information D3 from the leveled information D2 stored in the storage unit 23 (step S21). For example, the UI unit 25 displays a list of passenger information D1 stored in the storage unit 23, and accepts a selection operation of at least one passenger information D1.

Next, the communication unit 24 determines whether or not the selected passenger information D1 is information of a predetermined level of privacy level PL (step S22). For example, when the privacy level PL is the passenger information D1 of a predetermined level or less, the communication unit 24 determines that the passenger information D1 is the transmission target.

Next, the UI unit 25 accepts the selection of the communication device to be the transmission destination of the selected transmission information D3 (step S23). For example, the UI unit 25 displays a screen for selecting one of the communication devices 30 and 40 as the communication device of the transmission destination, and accepts the selection operation of the transmission destination.

Subsequently, the communication unit 24 selects a communication method for transmitting the transmission information D3 based on the privacy level PL of the transmission information D3 (step S24). For example, the communication unit 24 has a table (for example, FIG. 3) for selecting a communication method to be adopted according to the privacy level PL. Then, the communication unit 24 transmits the transmission information D3 using the selected communication method (step S25). For example, when the communication device 30 is selected as the transmission destination, the communication unit 24 transmits the transmission information D3 to the communication device 30.

Further, when the passenger information D1 that is not the transmission target and the passenger information D1 to which the privacy level PL of the level L4 is given in this embodiment is selected, the communication unit 24 does not transmit the passenger information D1 (step). S26). Further, in this case, the communication unit 24 notifies the user that the selected passenger information D1 is information that is not the transmission target and that the information is not transmitted. Specifically, the communication unit 24 instructs the UI unit 25 to indicate that the selected passenger information D1 is not transmitted.

The communication device 20 waits until it receives a new transmission request after transmitting the transmission information D3 or notifying that the transmission information D3 is not transmitted. In this way, the communication device 20 transmits the passenger information D1.

The transmission flow shown in FIG. 5 is only an example. For example, in a situation where real-time information is important in vehicle-to-vehicle communication and pedestrian-to-vehicle communication, the communication unit 24 provides passenger information of level L1 privacy level PL to which an unspecified number of communication devices are transmitted. For D1, broadcast transmission may be performed without accepting the selection input from the UI unit 25. Further, the communication unit 24 may be configured to repeatedly transmit the passenger information D1 of the level L1 over a plurality of times.

In this case, the communication unit 24, that is, the transmission unit provided by the vehicle or the pedestrian (communication terminal carried by the pedestrian) is in contact with the passenger information D1 at the level L1, for example, by a program, while moving. It must be set to broadcast, set to broadcast at a given time, or set to broadcast when it arrives at a given location (eg, destination). Just do it. This makes it possible to send useful information to others in real time while protecting privacy. The configuration and operation flow of the communication unit 24 described above are only an example.

FIG. 6 is a diagram schematically showing an example of a format of transmission data including transmission information D3 transmitted by the communication unit 24 of the communication device 20. As shown in FIG. 6, the communication unit 24 transmits serial data indicating a header, a privacy level PL, a position and address of the communication device 20, and passenger information D1 (two passenger information D1 in this embodiment). To do.

FIG. 7 is a diagram showing a reception flow of passenger information D1 by the communication device 30. The communication device 30 starts the information reception flow by receiving the transmission information D3 from the communication device 20 (step S31). For example, the communication unit 31 of the communication device 30 receives the communication request from the communication device 20 and receives the transmission information D3.

Next, the level determination unit 32 analyzes the transmission information D3 and determines the privacy level PL of the passenger information D1 (step S32). The level determination unit 32 has, for example, the same level determination table as the level assignment unit 22 of the communication device 20, and determines the privacy level PL of the passenger information D1 received according to the level determination table.

Subsequently, the display unit 33 displays the passenger information D1 (step S33). For example, the display unit 33 displays the passenger information D1 in an manner corresponding to the privacy level PL of the received passenger information D1. After displaying the passenger information D1, the communication device 30 ends the information reception flow and waits until the new passenger information D1 is received.

For example, when the communication device 20 includes the passenger information D1 in the device ID of Wi-Fi Direct (registered trademark) and transmits the data of the transmission information D3 of the level L1, the communication device 30 and the communication device 30 that received the data 40 can acquire passenger information D1 by analyzing the data according to a common arrangement rule in the communication system 10. Further, the communication devices 30 and 40 can recognize that the received data includes the passenger information D1 of the level L1.

On the other hand, consider a case where the communication device 20 includes the passenger information D1 in the device ID of Wi-Fi Direct (registered trademark) and transmits the data of the transmission information D3 of the level L2 to the communication device 30 as the transmission destination. In this case, since the arrangement rule of the transmitted data is set (arranged) only between the communication devices 20 and 30, only the communication device 30 can acquire the passenger information D1 and boarding. It can be recognized that the person information D1 is the information of the level L2.

However, the communication device 40 can receive the level L2 data transmitted to the communication device 30 (displayed as one of the device IDs of the communicable devices), but the analysis and information of the data. Cannot be converted. Further, when the communication device 20 communicates with the communication device 30 after authenticating using Wi-Fi Direct (registered trademark), the communication device 40 itself receives the data. Can not.

As described above, in the present embodiment, the communication unit 24 of the communication device 20 is a specific communication device (for example, for the passenger information D1 to which the privacy level PL of the level L2 or L3 (second level) is given. Data including passenger information D1 (data-converted transmission information D3) is arranged and transmitted to the communication device 30) in a specific arrangement order, or communication authentication is performed with the specific communication device. After that, the data including the passenger information D1 (data-converted transmission information D3) is transmitted. In this way, the confidentiality of the passenger information D1 according to the privacy level PL can be ensured.

Here, an example of the use of the communication system 10 will be described. For example, in the communication system 10, when a driver of an automobile picks up (picks up) a specific pedestrian who owns the communication device 30 among a plurality of pedestrians as a mobile body V1 equipped with the communication device 20. Can be used for. In this case, for example, by transmitting vehicle information and the fact that the vehicle is approaching as level L1 information, it is possible to call attention to, for example, all communicable pedestrians. At the same time, the communication device 30 can be notified as level L2 information that the owner of the communication device 30 is approaching.

Further, as another use, for example, when making an accommodation reservation between a family riding a car as a mobile body V1 equipped with a communication device 20 and an accommodation facility in which the communication device 30 is installed. Can be used. For example, if the communication devices 20 and 30 are registered as communication partners in advance, the arrival time, number of people, gender, etc. of the passengers can be transmitted only to the accommodation facility as the passenger information D1 of the level L2. Then, for example, if the accommodation facility is configured to receive a reply as to whether or not the accommodation is possible, it is possible to inquire whether or not the accommodation is possible easily and safely.

As described above, the communication device 20 has privacy regarding the passenger information D1 for each of the information acquisition unit 21 that acquires at least one passenger information D1 that is information about the passenger of the mobile body V1 and the passenger information D1. Level granting section 22 (classifier granting section) that assigns a privacy level PL (classifier) indicating the level (property of passenger information D1), and a predetermined level of privacy level PL (classification) among passenger information D1. It has a communication unit 24 that transmits the passenger information D1 to which the child) is attached. Therefore, it is possible to provide a communication device 20 capable of protecting privacy and safely performing mobile communication.

Further, the level giving unit 22 transmits the first level L1 indicating that an unspecified number of communication devices are to be transmitted and the specific communication device as the privacy level PL for each of the passenger information D1s. Either the second level L2 and L3 indicating that the image is to be transmitted and the third level L4 indicating that the device is not to be transmitted are assigned. Thereby, for example, information that is more useful to be transmitted to a large number of parties in the vicinity of the mobile body V1 and privacy information that should be transmitted only to a specific party can be classified.

Then, the communication unit 24 transmits only the passenger information D1 to which the first or second level (levels L1 to L3) is given. Therefore, for example, it is possible to call attention to itself (moving body V1) to all approaching pedestrians, and to transmit privacy information to specific pedestrians. Therefore, it is possible to easily realize both mobile communication that ensures privacy and suppression of traffic accidents.

Further, with respect to the passenger information D1 to which the second level (level L2 or L3) is given, the communication unit 24 arranges the data including the passenger information D1 in a specific arrangement order with respect to the specific communication device. Or, after performing communication authentication with a specific communication device, the data including the passenger information D1 is transmitted. Therefore, even when communicating with a specific communication device as a transmission target, the security level can be appropriately adjusted, and privacy can be appropriately protected.

Further, the present invention can also be implemented as a communication method by going through the flow shown in FIGS. 3 and 5, for example. Specifically, the communication method according to the present invention includes a step of acquiring at least one passenger information D1 which is information about a passenger of the moving body V1 and a step of acquiring the passenger information D1 for each of the passenger information D1. The step includes a step of assigning a classifier indicating the property, and a step of transmitting the passenger information D1 to which the predetermined classifier is assigned among the passenger information D1. Therefore, it is possible to provide a communication method capable of protecting privacy and safely performing mobile communication.

FIG. 8A is a diagram schematically showing the configuration of the program 50 according to the second embodiment and the communication device 50A in which the program 50 is installed.
