  The shared space access unit 56 is a part that performs access to the shared space. The access to the shared space includes the identifier of the shared space to be accessed, the operation content for the shared space, and the IP address of the second communication terminal 5.

  Next, the operation of the shared space management system 100 in the shared space management method of the present embodiment will be described with reference to FIG. FIG. 7 is a flowchart showing the processing contents executed in the shared space management system 100. For example, when a voice call is performed between the first communication terminal 3 and the second communication terminal 5, the user of the first communication terminal 3 and the second communication terminal 5 desires to share some data through the shared space. In this case, the processing shown in the flowchart of FIG. 7 is started.

  First, the token issue request unit 50 of the second communication terminal 5 transmits a token issue request to the shared space providing server 1 (S1). The token issue request includes an IP address that is an identifier for identifying the second communication terminal 5.

  Next, the token issue request accepting unit 10 of the shared space providing server 1 accepts a token issue request from the token issue request unit 50 (S2). Subsequently, the token issuing unit 11 generates a token in response to the token issuing request received by the token issuing request receiving unit 10 (S3). Further, the token issuing unit 11 stores the generated token in the issued token storage unit 12 (see FIG. 4) in association with the IP address of the second communication terminal 5 and the time when the token is generated (S4). Then, the token transmission unit 13 transmits the token generated by the token issuing unit 11 to the second communication terminal 5 (S5).

  Next, the token receiving unit 51 of the second communication terminal 5 receives the token returned from the shared space providing server 1 in response to the token issuance request (S6). Subsequently, the token display unit 52 displays a character string of the token on a device such as a display in order to present the token received by the token receiving unit 51 to the user of the second communication terminal 5 (S7).

  When the content of the character string of the token displayed on the token display unit 52 is uttered by the user of the second communication terminal 5, the utterance voice acquisition unit 53 of the second communication terminal 5 User utterance voice, which is utterance voice, is acquired (S8). Then, the utterance voice transmission unit 54 transmits the user utterance voice acquired by the utterance voice acquisition unit 53 to the first communication terminal 3 (S9).

  Next, the received voice receiving unit 30 of the first communication terminal 3 receives the user uttered voice transmitted from the second communication terminal 5 (S10). Subsequently, the received voice information transmitting unit 31 transmits the user uttered voice received by the received voice receiving unit 30 to the shared space providing server 1 (S11).

  Next, the received voice information acquisition unit 14 of the shared space providing server 1 acquires the user uttered voice transmitted from the first communication terminal 3 (S12). Subsequently, the voice recognition unit 15 converts the user utterance voice acquired by the received voice information acquisition unit 14 into text information by voice recognition processing (S13). Then, the token extraction unit 16 extracts the text information corresponding to the token from the text information obtained by the voice recognition unit 15 (S14).

  Next, the token determination unit 17 of the shared space providing server 1 performs authentication processing of the token extracted by the token extraction unit 16 (S15). Specifically, the token determination unit 17 matches the token character string extracted by the token extraction unit 16 with the token stored in the issuance token storage unit 12, and the time elapsed from the issue time of the token. When it is within a certain time (for example, about 10 seconds), the second communication terminal 5 is permitted to set an access right to the shared space. Thereby, the shared space providing server 1 can recognize that the first communication terminal 3 and the second communication terminal 5 are performing voice communication with each other.

  When the authentication is successful, that is, when setting of the access right is permitted for the second communication terminal 5 (S16), the processing procedure proceeds to step S18, and the access right is set for the second communication terminal 5. If the setting is not permitted (S16), the processing procedure proceeds to step S17.

  In step S17, error processing is performed. Specifically, for example, the shared space providing server 1 displays error information indicating that an error has occurred in the first communication terminal 3 and the second communication terminal 5.

  In step S18, shared space creation processing is performed. Next, the shared space creation process will be specifically described with reference to FIG. FIG. 8 is a flowchart showing in detail the shared space creation process.

  In the shared space creation process (S18), first, the shared space creation unit 21 of the shared space providing server 1 creates a shared space in the shared space storage unit 29 (S21). Subsequently, the access right setting unit 18 sets an access right for the first communication terminal 3 and the second communication terminal 5 (S22). Specifically, the access right setting unit 18 associates the IP address of the first communication terminal 3 and the IP address of the second communication terminal 5 with the identifier of the created shared space, and the shared space information storage unit 19 (FIG. 5). Register). Then, the access right setting unit 18 notifies the first communication terminal 3 and the second communication terminal 5 that the creation of the shared space and the setting of the access right are completed (S23).

  In the present embodiment, a shared space is created after the authentication process for the second communication terminal 5 is completed, and the IP address of the first communication terminal 3 is registered in the shared space information storage unit 19. It is not limited to. For example, prior to the processing procedure shown in step S1, a shared space creation request is transmitted from the shared space creation request transmission unit 34 of the first communication terminal 3 to the shared space creation request reception unit 20 of the shared space providing server 1, In response to the transmitted shared space creation request, the shared space creation unit 21 creates a shared space in the shared space storage unit 29 and registers the IP address of the first communication terminal 3 in the shared space information storage unit 19. Good.

  Next, processing contents of the shared space providing server 1 when the shared space is accessed from the first communication terminal 3 or the second communication terminal 5 will be described. FIG. 9 is a flowchart showing the processing contents of the shared space providing server 1.

  First, the shared space control unit 28 receives access to the shared space from the first communication terminal 3 or the second communication terminal 5 (S31). The access to the shared space includes the identifier of the shared space to be accessed, the operation content for the shared space, and the IP address of the transmission source communication terminal. The operation content for the shared space is, for example, writing of data to the shared space and reading of data stored in the shared space.

  Next, the shared space control unit 28 refers to the shared space information storage unit 19 and determines whether or not the IP address of the communication terminal is associated as the permitted IP address with the identifier of the shared space included in the access. Determine (S32). Thereby, it is determined whether or not the communication terminal is permitted to access the shared space. If the access is not permitted, the process procedure proceeds to step S33. In step S33, for example, error processing is performed such that error information indicating that an error has occurred is displayed on the communication terminal.

  If access is permitted, the procedure proceeds to step S34. In step S34, the shared space control unit 28 specifies a shared space based on the identifier of the shared space included in the access (S34), and performs the operation content corresponding to the received access on the specified shared space. (S35). Accordingly, the communication terminals that can access the shared space are limited to the communication terminals in the shared space information storage unit 19 in which the IP address is associated with the identifier of the shared space as the permitted IP address.

  In the shared space management system 100 according to the first embodiment described above, the token generated by the shared space providing server 1 and used for the authentication process is transmitted to the second communication terminal 5 and the user of the second communication terminal 5 is used. Is displayed. When the character string of the token uttered by the user of the second communication terminal 5 is acquired by the second communication terminal 5 as the user utterance voice, the user utterance voice is transmitted to the shared space providing server 1 via the first communication terminal 3. To be acquired. In the shared space providing server 1, since the issued token is stored in association with the identifier of the second communication terminal 5 that is the transmission source of the issue request, the character string extracted from the user uttered voice is stored. By determining whether or not the token matches, the access right to the shared space can be set in the second communication terminal 5 indicated by the identifier associated with the token. Therefore, this authentication process can limit access to the shared space to the first communication terminal 3 and the second communication terminal 5 during a voice call. In addition, the user of the second communication terminal 5 can complete the operation for the authentication process by an utterance operation while maintaining a call state with the first communication terminal 3 instead of an operation using a hand. Therefore, the operation burden on the user is reduced.

  In the present embodiment, since the shared space providing server 1 performs the conversion process from the user uttered voice to the text information, the first communication terminal 3 does not need to have a special voice recognition function. Accordingly, the processing load on the first communication terminal 3 is reduced.
