DETAILED DESCRIPTION

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a system diagram illustrating a position verification system 1 according to an exemplary embodiment of the present invention.

The position verification system 1 according to the exemplary embodiment of the present invention, as illustrated in FIG. 1, includes a portable terminal apparatus 10 such as a personal computer, a smart phone, and a tablet terminal apparatus, a server apparatus 12 which is a control apparatus, and a beacon 14 which is a radio beacon.

Any terminal apparatus is applicable to the terminal apparatus 10 of the present invention, as long as the terminal apparatus can be connected to the server apparatus 12 through a communication network.

The terminal apparatus 10 and the server apparatus 12 are connected through a wireless LAN terminal such as a Wi-Fi router, or the Internet communication network, and thereby transmit and receive information.

The beacon 14 includes a device of generating radio waves such as Wi-Fi and is provided in a place for which position information is desired to be acquired. The beacon 14 is provided, for example, indoors such as in each conference room and always transmits radio waves (beacon information) about an ID for identifying the beacon.

In the indoor space where the beacon 14 is provided, the terminal apparatus 10 recognizes a distance from the beacon 14 based on the received signal strength indication (RSSI) of the radio waves transmitted from the beacon 14 and then transmits beacon information which is the acquired position information to the server apparatus 12 to acquire its own position information. The terminal apparatus 10 is able to perform short-range communication with other terminal apparatuses which are located within a short distance. The terminal apparatus 10 is able to receive data from the server apparatus 12 or receive a decryption key to decrypt the encrypted data.

Further, the control program can be obtained by downloading through the Internet communication network or a mobile telephone network and be provided to the CPU 16, or the control program can be stored in a recording medium such as a CD-ROM and be provided to the CPU 16 by stored.

The short-range communication device 23 transmits and receives terminal information by performing short-range communication with the terminal apparatuses 10 which are located within a short distance and transmitting and receiving data. As the short-range communication device 23, an infrared communication device that performs communication by using infrared, Bluetooth (registered trademark), a non-audible sound communication device using the microphone 22 and a speaker, or the like are used.

The terminal apparatus 10 according to the present exemplary embodiment performs an operation as described below in response to the execution of the control program, and enables, for example, the reception of data required for a conference, or the viewing of data.

FIG. 3 is a block diagram illustrating a functional configuration of the terminal apparatus 10 which is implemented by the execution of the control program.

As illustrated in FIG. 3, the terminal apparatus 10 according to the exemplary embodiment includes a position information acquisition unit 32, a terminal information transmitting and receiving unit 34, a control unit 36, a storage unit 38, a display unit 40, and a communication unit 42.

The position information acquisition unit 32 acquires beacon information of the beacon 14 which is provided in the proximity of the terminal apparatus 10.

The terminal information transmitting and receiving unit 34 communicates with other terminal apparatuses which are within a short distance, by using the short-range communication device 23, and transmits and receives each terminal information.

Further, the control unit 36 performs control so as to display the position information and the acquired position verification information on the display unit 40.

Next, the functional configuration of the server apparatus 12 according to the present exemplary embodiment of the present invention will be described with reference to the block diagram of FIG. 4.

According to FIG. 4, the server apparatus 12 according to the present exemplary embodiment includes a communication unit 44, a control unit 46, a position information storage unit 48, a position information detection unit 50, a schedule storage unit 52, a schedule information detection unit 53, a determination unit 54, and an approving unit 56.

The position information storage unit 48 stores information about the output values (received signal strengths) of plural beacons 14.

The position information detection unit 50 calculates a distance between the terminal apparatus 10 and the beacon 14, based on the beacon output value (received signal strength) that the terminal apparatus 10 acquires, and specifies a beacon 14 which is located at the nearest location among plural pieces of beacon information which are stored in the position information storage unit 48 to detect the position (place) of the terminal apparatus 10.

As illustrated in FIG. 5, the schedule storage unit 52 stores plural pieces of information such as dates and times, locations, participants, and distributed materials. The date and time is stored as time information, the place is stored as position information, and the participant is stored as the terminal information of the terminal apparatus 10 that the participant uses.

The schedule information detection unit 53 detects schedule information at a date and a time at which the terminal apparatus 10 accesses the server apparatus 12, based on the time information (the date and the time in FIG. 5) which is stored in the schedule storage unit 52, from the date and the time.

The determination unit 54 determines whether or not the position information (the place in FIG. 5) of the schedule information, which is detected by the schedule information detection unit 53, is coincident with the position information, which is acquired from the terminal apparatus 10. Further, the determination unit 54 determines whether or not the terminal information of the terminal apparatus 1 acquired as the position verification information is present in the terminal information (the participant in FIG. 5) of the detected schedule information.

In a case where the determination unit 54 determines that the acquired position information is coincident with the position information of the schedule information or determines that the acquired position information is coincident with the position information of the schedule information and a case where there is terminal information of a terminal apparatus which is verified based on the position verification information, among plural pieces of the terminal information of the schedule information, the approving unit 56 approves the transmission of data of schedule information. The approving unit 56 approves the transmission of a decryption key to decrypt the encrypted data and approves the viewing of data having viewing restriction.

In addition, although the present exemplary embodiment has described an example in which data is stored in the schedule storage unit 52 as schedule information, it is not limited thereto. A data storage unit may be provided in the server apparatus 12, plural pieces of data to be transmitted to the terminal apparatus 10 may be stored in the data storage unit, and the transmission of data which is requested from the terminal apparatus 10 may be approved. In addition, plural pieces of data include encrypted data.

In a case where the position information is acquired from the terminal apparatus 10, the control unit 46 controls to calculate the position information based on the plural pieces of data which are stored in the position information storage unit 48, detects the position of the terminal apparatus 10, and thus transmits the position to the terminal apparatus 10 through the communication unit 44. Further, the control unit 46 controls the approving unit 56 to permit the transmission of data, based on the acquired position information or position verification information, and controls to transmit data to the terminal apparatus 10 through the communication unit 44, transmits a decryption key of the encrypted data, or releases the viewing limit of data to enable the viewing of the data.

Next, the operation of the position verification system 1 according to the exemplary embodiment of the present invention will be described in detail.

FIG. 6 is a flowchart illustrating the operation of the position verification system 1 according to the exemplary embodiment of the present invention. FIG. 7 is a flowchart illustrating the details of a data transmission approving process of step 108. FIG. 8 is a diagram illustrating the operations of terminal apparatuses 10a, 10b, and 10c and the beacon 14 in the conference room A. In the present exemplary embodiment, the operation of the position verification system 1 will be described, with a case of respectively transmitting data 1 which is distributed material in a conference, which is held at the conference room A, 2015/12/25 15:00-16:00, participants a, b, and c, among schedule information of FIG. 5 from the server apparatus 12 to the terminal apparatuses 10a, 10b, and 10c of the participants a, b, and c, as an example. The beacon 14 is provided in the conference room A. In addition, FIG. 6 is focused on the operation of the terminal apparatus 10a, and since the configurations and operations of the terminal apparatus 10b and the terminal apparatus 10c are those of the terminal apparatus 10a, the decryption thereof will be omitted.

In step 100 (S100), the beacon 14 always transmits radio waves (beacon information) about an ID for identifying the beacon.

In step 101 (S101), the terminal apparatus 10a transmits the beacon information which is acquired from the beacon 14, to the server apparatus 12.

In step 102 (S102), the server apparatus 12 calculates the position information based on the beacon information which is received from the terminal apparatus 10a, detects the position of the terminal apparatus 10a by using the position information detection unit 50, and transmits the detected position to the terminal apparatus 10a. The schedule information detection unit 53 detects schedule information, based on the time information (2015/12/25 15:00-16:00 in the present exemplary embodiment) which is stored in the schedule storage unit 52, from a date and a time at which the terminal apparatus 10a accesses the server apparatus 12.

Next, in step 103 (S103) and step 104 (S104), as illustrated in FIG. 8, the terminal apparatuses 10a, 10b, and 10c in the conference room A perform the short-range communication by using the respective short-range communication devices 23. Specifically, the terminal apparatus 10a transmits its own terminal information to the other terminal apparatus 10b and terminal apparatus 10c in the conference room A (S103). The terminal apparatus 10b and the terminal apparatus 10c transmit a notification that the terminal information of the terminal apparatus 10a is recognized (S104).

In step 105 (S105), since it is recognized that the terminal apparatus 10a is located within a short distance from the terminal apparatus 10b and the terminal apparatus 10c w in the conference room A, the terminal apparatus 10a transmits position verification information to the server apparatus 12.

In step 106 (S106), the server apparatus 12 acquires the position verification information from the terminal apparatus 10a.

In other words, after the server apparatus 12 acquires the beacon information and the schedule information of each of the terminal apparatuses 10a, 10b, and 10c which are in the conference room A, the terminal apparatuses 10a, 10b, and 10c, which are used by the participants a, b, and c included in the schedule information, perform the short-range communication such as infrared communication to transmit and receive the terminal information with each other, and exchange data with each other, such that it is verified that the terminal apparatus 10a is close to other terminal apparatuses which are used by participants of a conference in the conference room A, and the position information which is acquired from the beacon 14 is verified to be correct. In other words, the position information of the participant which receives the terminal information in the conference room A is specified by performing short-range communication, and the authenticity of position information is guaranteed.

Then, in step 107 (S107), the terminal apparatus 10a makes a request for transmitting the data which is distributed material for a conference stored in the schedule storage unit 52, to the server apparatus 12.

In step 108 (S108), the server apparatus 12 determines whether or not the transmission of the requested data is approved. Step 108 (S108) will be described in detail.

In step 201 (S201), it is determined whether or not the position information detected in step 102 (S102) is coincident with the position information (the conference room A in the present exemplary embodiment) of the schedule information detected in step 102 (S102). If it is determined that the position information are coincident with each other, the process proceeds to next step 202 (S202); and if it is determined that both of the position information are not coincident with each other, the process is ended (the transmission of data to the terminal apparatus 10a is not approved).

In step 202 (S202), it is determined whether or not the terminal information of the terminal apparatus 10b, which is acquired as the position verification information in step 106 (S106), is present in the terminal information of the schedule information which is detected in step 102 (S102). In a case where the terminal information of the terminal apparatus 10b is present in the terminal information of the schedule information, the process proceeds to next step 204 (S204), the transmission of data is approved, and data is transmitted to the terminal apparatus 10a. In a case where the terminal information of the terminal apparatus 10b is not present in the terminal information of the schedule information, the process proceeds to next step 203 (S203).

In step 203 (S203), it is determined whether or not the terminal information of the terminal apparatus 10c, which is acquired as the position verification information in step 106 (S106), is present in the terminal information of the schedule information which is detected in step 102 (S102). In a case where the terminal information of the terminal apparatus 10c is present in the terminal information of the schedule information, the process proceeds to next step 204 (S204), the transmission of data is approved, and data is transmitted to the terminal apparatus 10a. In a case where the terminal information of the terminal apparatus 10c is not present in the terminal information of the schedule information, the process is ended (the transmission of data to the terminal apparatus 10a is not approved).

In other words, if the position information are coincident with each other and if the terminal information is present in the terminal information of the schedule information, the transmission of data is approved. The transmission of a decryption key to decrypt the encrypted data is approved, or the viewing of data having viewing restriction is approved.

In step 109 (S109), the terminal apparatus 10a receives data which is approved based on each of position verification information.

In addition, although the exemplary embodiment has described an example in which data is transmitted from the server apparatus 12 to the terminal apparatus 10 in a case where the transmission request is approved, it is not limited thereto. A decryption key to decrypt encrypted data which is already transmitted may be transmitted, or the viewing limit or the editing limit applied to the data in the server apparatus 12 may be released.

It should be noted that the present invention is not limited to the above exemplary embodiment, and various modifications are possible.
