About.

  Conventionally, providing a service from a server to a communication terminal has been widely performed. Such a service is usually performed only for a specific communication terminal, and therefore, access authentication is generally performed when starting the service.

  It is widely known that a terminal ID / password, a one-time password, a digital certificate, or the like is used as a means for access authentication of a communication terminal. There is also known a method of performing access authentication using position information of a communication terminal obtained by using a radio base station and position information acquired by GPS.

  For example, in the following Patent Document 1, when there is a connection request from a portable terminal, a user identifier, a password, and position information of the portable terminal are acquired from the portable terminal, and predetermined information is transferred to the portable terminal based on information accessible information. Information providing server to be transmitted to is described.

  Further, in Patent Document 2 below, when a user accesses a confidential document server using a client PC, the client PC acquires the position information from the portable terminal and transfers the acquired position information to the confidential document server. It is described. It is described that the confidential document server prohibits the client PC from accessing the confidential document if the location information of the mobile terminal is outside the service usage range registered in advance.

  Further, Patent Document 3 below describes a content server that provides a limited service to a communication terminal according to service definition data corresponding to the region definition data including the position of the communication terminal found in the database. .

[Embodiment 1]
Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS.

<Overview of operation>
First, an operation outline of the service providing system according to the first embodiment of the present invention will be described with reference to FIG. 2A and 2B are diagrams showing an outline of the operation of the service providing system 1. FIG. 2A shows an operation at the time of authentication, and FIG. 2B shows an operation after the authentication.

  The service providing system 1 shown in FIG. 2 includes a communication terminal 10, a service server (connection control device, service providing device) 20, a content server 30, a display device 41, and an output device (audio output device) 40. Including. The service server 20 and the content server 30, the service server 20 and the communication terminal 10, and the service server 20 and the output device 40 are each configured to perform data communication via a network.

  The service providing system 1 is a system that provides a predetermined service from the service server 20 to the communication terminals 10 around the output device 40 (within the service providing area). Since the display device 41 is disposed in the vicinity of the output device 40, the service providing area can be said to be an area around the display device 41.

  In the service providing system 1, in order to provide a service only to the communication terminal 10 near the output device 40 (display device 41), the communication terminal 10 is first authenticated when providing the service. This authentication will be described with reference to FIG.

  In the example of FIG. 5A, the service server 20 receives content data from the content server 30 and transmits it to the output device 40. The output device 40 receives and outputs the content data. The content data is data including audio data such as music and environmental sounds.

  At the time of authentication, the service server 20 acquires sensor information detected by a sensor included in the communication terminal 10 from the communication terminal 10. Here, the communication terminal 10 includes a microphone (hereinafter simply referred to as a microphone) that acquires the voice around the terminal as voice data, and the voice data acquired by the microphone is used as the sensor information in the service server 20. Assume uploading.

  Then, the service server 20 collates the sensor information (audio data) acquired from the communication terminal 10 with the content data, and determines whether the communication terminal 10 is in the service providing area.

  As described above, since the content data is output from the output device 40, if the communication terminal 10 exists near the output device 40, the sound output from the output device 40 is reflected in the sensor information transmitted by the communication terminal 10. Is done.

  For this reason, by collating sensor information and content data, it can be determined whether the communication terminal 10 exists near the output device 40, that is, whether the communication terminal 10 is in the service providing area.

  Here, if it is determined that the communication terminal 10 is within the service providing area, the service server 20 determines that the authentication is successful, establishes a communication connection (session) with the communication terminal 10, and passes through the communication connection. Service provision to the communication terminal 10 is started. On the other hand, if it is determined that the communication terminal 10 is outside the service providing area, it is determined that the authentication has failed. In this case, communication connection is not performed and service provision is not started.

  As described above, according to the service providing system 1, it is possible to provide a service only to the user of the communication terminal 10 in the vicinity of the display device 41 (output device 40).

  Here, as shown in FIG. 5B, the communication terminal 10 that has succeeded in the authentication and has established the communication connection with the service server 20 transmits a survival response and the sensor information of its own device to the service server 20.

  In the figure, an example in which communication between the communication terminal 10 and the service server 20 is bidirectional communication is shown, but unidirectional communication may be used. The survival response may be transmitted using a two-way communication session. In addition, although the example in which the communication between the display device 41 and the service server 20 is also bidirectional communication is shown, the display device 41 and the service server 20 do not necessarily perform communication and perform communication. The case may be bidirectional communication or unidirectional communication. However, when configured to be communicable, an image relating to the service can be displayed on the display device 41, such as displaying a service notification on the display device 41, so that the display device 41 and the service server 20 communicate with each other. It is preferable to be able to be configured.

  Then, the service server 20 collates the sensor information received from the communication terminal 10 and the content data in the same manner as at the time of authentication. If it is determined that the communication terminal 10 is in the service providing area, the communication connection is maintained and the service is continuously provided. On the other hand, when it is determined that the communication terminal 10 is outside the service providing area, the communication connection is disconnected and the service provision ends. Thereby, it is possible to stop providing services to the communication terminal 10 that is remote from the output device 40 after authentication.

<Main part configuration>
Next, the configuration of each device included in the service providing system according to the present invention will be described with reference to FIG. FIG. 1 is a block diagram showing a main configuration of communication terminal 10 and service server 20 included in service providing system 1 shown in FIG.

(Communication terminal 10)
The communication terminal 10 is a terminal device that receives provision of services, and includes an input unit 100, a communication terminal control unit 110, a communication terminal sensor unit 120, a display unit 130, and a communication terminal communication unit 140.

  The input unit 100 receives an operation of the user of the communication terminal 10 and sends the operation content to the communication terminal control unit 110.

  The communication terminal control unit 110 controls the communication terminal 10 in an integrated manner. Specifically, a process of transmitting the sensor information of the communication terminal 10 to the service server 20 and a process of displaying the service data received from the service server 20 on the display unit 130 are performed.

  The communication terminal sensor unit 120 is for the communication terminal 10 to generate sensor information from voices around its own device. Specifically, the communication terminal sensor unit 120 is a microphone that converts sound around the communication terminal 10 into sound data, and this sound data is referred to as sensor information. This sensor information is transmitted to the service server 20 via the communication terminal communication unit 140.

  The display unit 130 is for displaying an image. As described above, service data received from the service server 20 is displayed on the display unit 130.

  The communication terminal communication unit 140 is for the communication terminal 10 to communicate with an external device. Specifically, the communication terminal communication unit 140 transmits / receives data to / from the service server communication unit 200 of the service server 20 via the network.

(Service server 20)
The service server 20 is a server that provides services to the communication terminal 10 and causes the output device 40 to transmit and output content. As illustrated, the service server 20 includes a service server communication unit 200, a service server control unit 210, and a storage unit 220.

  The service server communication unit 200 is for the service server 20 to communicate with an external device. Specifically, the service server communication unit 200 transmits / receives data to / from the communication terminal 10, the content server 30, and the output device 40 via a network. When the service server communication unit 200 receives data, the service server communication unit 200 sends the received data to the service server control unit 210. In addition, although the example which communicates with the communication terminal 10 and the output device 40 by one service server communication part 200 is demonstrated here, you may communicate via these apparatuses and a separate communication part, and the communication Each method may be different.

  The service server control unit 210 performs overall control of the service server 20, and includes a sensor information acquisition unit (terminal audio acquisition unit) 213, a verification unit (determination unit) 214, and a content transmission unit (audio output control unit) 211. , A verification target data acquisition unit 212, and a service control unit (connection control means) 215.

  The sensor information acquisition unit 213 receives the sensor information (terminal voice data) via the service server communication unit 200 and sends it to the verification unit 214. The sensor information acquisition unit 213 may process the received sensor information so that the collation unit 214 can easily collate. For example, when the data size of the sensor information exceeds a predetermined threshold value, the data size may be equal to or smaller than the threshold value by thinning out the sensor information data or extracting a part thereof. Further, processing such as applying a filter for reducing noise may be performed.

  The content transmission unit 211 transmits the content data received from the content server 30 to the output device 40 for output. More specifically, the content transmission unit 211 performs streaming distribution of content data. That is, the output device 40 reproduces the portion of the content data up to the position where the content transmission unit 211 has been distributed.

  The collation target data acquisition unit 212 generates data to be collated with the sensor information (hereinafter referred to as collation target data) from the content data being transmitted by the content transmission unit 211. Specifically, the collation target data acquisition unit 212 extracts audio data for a predetermined time before the current distribution position of the content data being transmitted from the content data and sets it as collation target data. The predetermined time here is a time set in advance by the service server 20.

  For example, the content data is audio data with a reproduction time of 10 minutes, the current distribution position is 5 minutes and 30 seconds, and the predetermined time is 1 minute. In this case, the collation target data acquisition unit 212 extracts the data from the current distribution position to one minute before, that is, the audio data from 4 minutes 30 seconds to 5 minutes 30 seconds from the content data, and sets the data as collation target data. .

  The collation unit 214 collates the sensor information received from the sensor information acquisition unit 213 and the collation target data received from the collation target data acquisition unit 212 to determine whether the communication terminal 10 is in the service providing area. Specifically, the collation unit 214 generates waveform data in which the amplitude of speech is plotted in time series from the collation target data. Similarly, waveform data is generated from the sensor information. Then, when the waveform data of the sensor information matches a part of the waveform data of the verification target data with a predetermined accuracy, it is determined that the sensor information is within the service providing area. This determination result is transmitted from the collation unit 214 to the service control unit 215.

  Here, an example in which the collation target data generated by the collation target data acquisition unit 212 is used will be described. However, the collation unit 214 may be configured to generate the collation target data. In this case, the verification target data acquisition unit 212 is omitted.

  Moreover, the collation part 214 should just be what can determine whether sensor information contains the audio | voice currently output in the service provision area, and the determination method is not restricted to said example.

  For example, determination audio data for determination is included as part of the content data from the output device 40 or as data different from the content data, and the waveform data obtained from the sensor information includes the determination audio data. It may be determined whether a waveform is included.

  In this case, since the waveform of the determination sound data can be acquired in advance, it is not necessary to generate the verification target data in the verification target data acquisition unit 212. In this case, the determination system can be improved by using waveform determination sound data that is hardly affected by noise around the output device 40. In addition, it is possible to use determination sound data that outputs sound having a wavelength that cannot be heard by a human ear or difficult to hear.

  The service control unit 215 performs processing for providing a service to the communication terminal 10. Specifically, the service control unit 215 receives the determination result indicating that the communication terminal 10 is in the service providing area from the verification unit 214 when receiving the service start request from the communication terminal 10. Establish communication connection with. Then, the service data 221 is read from the storage unit 220 and transmitted to the communication terminal 10 via the established communication connection, whereby the service provision is started.

  The service control unit 215 also functions as a display control unit that causes the display device 41 to display an image related to the service. Examples of the service-related image include a service notification image and an image presented to a person receiving the service.

  The storage unit 220 stores various data used by the service server 20, and the illustrated storage unit 220 stores service data 221 used by the service control unit 215 to provide services.

(Content Server 30)
The content server 30 is a server that distributes content data. As described above, the service server 20 acquires content data from the content server 30, transmits it to the output device 40, and outputs it.

(Output device 40)
The output device 40 is a device that receives and outputs content data. More specifically, the output device 40 is configured to be able to communicate with the service server 20 via a network, and outputs content data received from the service server 20 as sound.

<Processing operation of service providing system>
Next, the flow of processing in the service providing system 1 will be described with reference to FIG. FIG. 6 is a flowchart illustrating an example of processing (connection control method) in the service providing system 1.

  The content server 30 provides content data to the service server 20 (S140). Then, the content transmission unit 211 of the service server 20 receives the content data via the service server communication unit 200 (S120).

  Next, the content transmission unit 211 transmits the content data to the output device 40 via the service server communication unit 200 (S122). Then, the output device 40 receives the content data (S160) and outputs it (S162).

  Here, in order to use the service provided by the service server 20, the user of the communication terminal 10 inputs the address of a Web page for participating in the service from the input unit 100 or starts a predetermined application. Perform operations to participate in the service.

  In response to this operation, the communication terminal control unit 110 of the communication terminal 10 generates voice data from the voice around the communication terminal 10 in the communication terminal sensor unit 120, and uploads this to the service server 20 as sensor information (S100). ), Request the start of the service. At this time, when the user is in the vicinity of the output device 40, the sound indicated by the sensor information includes the sound output by the output device 40.

  The sensor information acquisition unit 213 of the service server 20 receives the sensor information via the service server communication unit 200 (S124, terminal voice acquisition step) and transmits it to the verification unit 214.

  In addition, the service control unit 215 that has confirmed that a service start request has been issued instructs the verification target data acquisition unit 212 to generate verification target data. The collation target data acquisition unit 212 that has received this instruction extracts a portion used by the collation unit 214 for collation from the content data being transmitted to the output device 40, and transmits this to the collation unit 214 as collation target data.

  Next, the collation unit 214 determines whether the sensor information received from the sensor information acquisition unit 213 matches the content data (collation target data) received from the verification target data acquisition unit 212 (S126, determination step). Note that the match in S126 means that the sensor information includes the voice output in the service providing area, and does not include the mismatch.

  Then, the collation unit 214 notifies the service control unit 215 of the result of this determination. That is, when it is determined that they match (YES in S126), a notification that they match is notified, and when it is determined that they do not match (NO in S126), a notification that they do not match is notified.

  Here, when notified that they match, the service control unit 215 establishes a communication connection with the communication terminal 10 and uses the communication connection to transmit the service data 221 read from the storage unit 220 to the communication terminal 10. Send to. Thereby, service provision to the communication terminal 10 is started (S128, connection control step). And the communication terminal control part 110 of the communication terminal 10 receives the said service data via the communication terminal communication part 140 (S102), and displays it on the display part 130. FIG.

  On the other hand, when notified that they do not match, the service control unit 215 determines whether or not a communication connection with the communication terminal 10 has been established (S130). Since the communication connection has not been established at the time of authentication, NO is determined in S130, and the process returns to S120 without providing the service to the communication terminal 10.

  The above is the process at the time of authentication of the communication terminal 10. Next, processing after the communication terminal 10 succeeds in authentication and starts using the service will be described. Note that the description of the same processing as that at the time of authentication is simplified.

  After starting to use the service, the communication terminal 10 acquires the voice around the device at regular time intervals and uploads the sensor information to the service server 20 (S100). The sensor information upload timing is not limited to a certain time interval, and may be uploaded at random time intervals.

  In the service server 20, the sensor information acquisition unit 213 receives the sensor information (S 124) and transmits it to the verification unit 214. In addition, the service control unit 215 that has confirmed uploading of the sensor information from the communication terminal 10 that is providing the service causes the verification target data acquisition unit 212 to generate verification target data. As a result, the title target data that is part of the content data is transmitted to the matching unit 214.

  Next, the collation unit 214 collates the sensor information with the collation target data to determine whether they match (S126), and notifies the service control unit 215 of the determination result.

  Here, when the notification of matching is received, the service control unit 215 continues to provide the service (S128). Then, the communication terminal 10 continues to receive the service (S102). That is, in this case, the communication connection between the communication terminal 10 and the service server 20 is maintained, and the provision of the service via this communication connection is continued.

  On the other hand, when the notification indicating that they do not match is received, the service control unit 215 determines whether or not a communication connection with the communication terminal 10 is established (S130). Since the communication connection has been established after the authentication, the service control unit 215 determines YES in S130, disconnects the communication connection with the communication terminal 10, and ends the provision of the service (S132). Note that when the service provision is terminated, the communication terminal 10 may be notified of the fact before the communication connection is disconnected.

〔Concrete example〕
Next, an example in which the service providing system 1 provides a visitor-limited chat service will be described with reference to FIG. FIG. 7 is a diagram for explaining an example of the case where the service providing system 1 provides a visitor-limited chat service.

  More specifically, in FIG. 7, a display device 41 having an output device 40 is arranged at a position that can be seen by visitors waiting for the turn of a vehicle or the like in an amusement facility such as a theme park or an amusement park. . And the service which displays the message which the visitor wrote in the communication terminal 10 on the display apparatus 41 is illustrated. According to such a service, it is possible to distract the visitors waiting for the turn and to promote exchange between the visitors.

  As shown to (a) of the figure, the output device 40 is provided in the display device 41, and outputs the content data received from the service server 20. The content data may be data including sound such as BGM or environmental sound, or may be sound data related to a service such as a service theme song or a sound notifying the service.

  A visitor carrying the communication terminal 10 approaches the display device 41 including the output device 40. Then, the communication terminal 10 is operated to input a predetermined URL. As a result, a screen for participating in the visitor-limited chat is displayed on the communication terminal 10 as shown in FIG.

  The service server 20 may include an address transmission unit that transmits a QR code (registered trademark) including the URL (address information for accessing the service server 20) to the display device 41 for display. Thereby, the trouble of inputting the URL of the user of the communication terminal 10 can be saved. Further, when the display device 41 has a function of generating a QR code (registered trademark) from a URL, the URL may be transmitted. In these cases, the display device 41 functions as an address information providing device that displays address information.

  Further, when the display device 41 includes a short-range communication unit for communicating with a device at a short distance, the address transmission unit transmits a URL to the display device 41 and receives the URL from the short-range communication unit. Broadcast transmission may be performed. Thereby, the URL can be notified only to the communication terminal 10 located near the display device 41. The device that broadcasts the address information may be any device that is arranged in the service providing area, and may be the output device 40 or another device. In these cases, the display device 40, the output device 40, or the other device described above functions as an address information providing device that transmits address information to the communication terminal 10 in the service providing area.

  Here, when selecting “participate” in the visitor-limited chat, the communication terminal 10 collects sounds around the own device by the communication terminal sensor unit 120 to generate sensor information and uploads the service server 20. And the service server 20 which received sensor information produces | generates collation object data from the content data currently transmitted to the output device 40, and collates with the uploaded sensor information.

  Here, since the communication terminal 10 is in the vicinity of the output device 40, the sensor information includes the sound output by the output device 40. Therefore, it is determined that the sensor information matches the verification target data, and the service server 20 starts providing a service to the communication terminal 10. That is, the service server 20 establishes a communication connection with the communication terminal 10 and provides a visitor-limited chat service to the communication terminal 10 via this communication connection.

  Thereby, as shown in (c) of the figure, the communication terminal 10 can participate in the visitor-limited chat and send and receive messages. Note that since a communication connection is established between the service server 20 and the communication terminal 10, the owner of the communication terminal 10 is limited to visitors via this communication connection as long as the owner of the communication terminal 10 is near the output device 40. You can continue to participate in the chat.

  On the other hand, if the owner of the communication terminal 10 is away from the output device 40, the sensor information acquired by the communication terminal 10 may or may not include the voice output by the output device 40. It becomes difficult to identify the sound from the sensor information. That is, it is determined that the sensor information and the verification target data do not match.

  Thereby, the service server 20 determines to terminate the communication connection and end the provision of the service to the communication terminal 10. At this time, when the service server 20 notifies the communication terminal 10 of the end of service provision, the communication terminal 10 displays that fact. For example, as shown in (d) of the figure, the communication terminal 10 may display that it has been disconnected from the service due to leaving the facility.

  As shown in FIG. 7D, when the owner of the communication terminal 10 moves away from the display device 41, the service provision itself may be stopped. Offering may be continued. For example, when the user is away from the display device 41, he / she cannot participate in the visitor-limited chat (write a message), but may be able to see the log of the chat.

  Further, the service control unit 215 may vary the content of the service provided according to the sensor information, that is, the volume of the sound indicated by the voice data generated by the communication terminal 10. For example, different messages may be displayed depending on the volume of sound. In addition, when there are a plurality of communication terminals 10 that intend to participate in the service, the service may be preferentially provided to the communication terminal 10 that has transmitted the sensor information having the largest sound volume, and the order of the sound volume Different contents may be provided depending on the service. In this case, the service control unit 215 also functions as a service control unit that varies the contents of the service to be provided according to the volume of sound indicated by the received audio data. Note that the comparison of the sound volume can be performed by regarding the sound data waveform (amplitude) as the sound volume.

  In the above example, the end of the service is determined based only on whether the sensor information matches the verification target data. However, the end of the service may be determined in consideration of other factors. For example, even if the sensor information matches the data to be verified, such as when the communication terminal 10 participates in the visitor-only chat and one hour has passed, the service provision is stopped. Service provision may be stopped.

  As described above, in the service providing system 1, collation target data extracted from the content data is collated with the sensor information generated from the sound around the communication terminal 10 by the communication terminal 10. A service is provided when sounds around the communication terminal 10 include sounds based on the content data.

  In this way, unauthorized use of the service can be made difficult by using sensor information that cannot be acquired unless it exists near the output device 40 at the time of authentication or survival response.

  This is because, if it is not known what content data is output from the output device 40, the sensor information that matches the verification target data cannot be disguised. Further, even if the content data output from the output device 40 is acquired, if it is not known which part of the content data is output at the time of authentication or survival response, the sensor information that matches the verification target data This is because it cannot be disguised.

  Even if the authentication is successful using, for example, recorded voice data, it is difficult to continue generating sensor information that matches the data to be collated with time unless it is in the vicinity of the output device 40. It is even more difficult to continue receiving services.

  Therefore, by using the service providing system 1, for example, when providing an event-limited service or a region-limited service, it is possible to receive an unauthorized service compared to a conventional configuration in which authentication is performed using identification information and location information of a communication terminal. Can be made more difficult.

  In the service providing system 1, generally distributed devices can be applied as the content server 30, the output device 40, and the display device 41 that constitute the system. And since a communication terminal such as a smartphone that is generally distributed has a microphone, it can function as the communication terminal 10 as long as it has a function of transmitting sensor information by installing application software, for example. Is possible.

[Embodiment 2]
In the service providing system 1 of the above-described embodiment, since the verification target data extracted from the content data is used for verification, it may be difficult to apply to the case where an entity other than the service server 20 transmits the content data. .

  Therefore, in the present embodiment, a service providing system that can be applied even when an entity other than the service server transmits content data will be described with reference to FIGS. In addition, the same reference number is attached | subjected to the structure similar to the said embodiment, and the description is abbreviate | omitted.

<Overview of operation>
First, an outline of the operation of the service providing system according to the present embodiment will be described with reference to FIG. FIG. 8 is a diagram showing an outline of the operation of the service providing system 2 that uses voice data acquired by an input device arranged in the vicinity of the output device for collation. FIG. 8A shows an operation at the time of authentication. FIG. 5B shows the operation after authentication.

  The service providing system 2 in FIG. 8 includes a communication terminal 50, a service server (connection control device, service providing device) 60, a content server 70, an output device 80, a display device 81, and an input device (audio data acquisition device). ) 90. The service server 60 and the communication terminal 50, the service server 60 and the input device 90, and the content server 70 and the output device 80 are configured to perform data communication via a network.

  In FIG. 5A, the output device 80 receives content data from the content server 70. The input device 90 is in the vicinity of the output device 80, generates voice data from the sound output from the output device 80, and transmits it to the service server 60.

  Thus, in the service providing system 2, the content server 70 transmits content data, and the service server 60 is not involved in the transmission of content data. For this reason, the service server 60 uses the voice data received from the input device 90 for verification.

  That is, in the service providing system 2, the communication terminal 50 transmits audio data generated from the surrounding audio to the service server 60, and the input device 90 transmits audio data reflecting the content data output from the output device 80. .

  For this reason, as shown in (a) of the figure, when the communication terminal 50 exists near the output device 80, the audio data from the communication terminal 50 and the audio data from the input device 90 are Match with some degree of accuracy. Therefore, by collating both audio data, whether or not the communication terminal 50 exists near the output device 80 from the degree of coincidence, in other words, whether or not the communication terminal 50 exists in the service providing area. Can be determined. As a result, as in the above-described embodiment, it is possible to start providing services only to the communication terminals 50 existing in the service providing area.

  Here, as shown in FIG. 5B, the communication terminal 50 that has succeeded in the authentication and established the communication connection with the service server 60 transmits the survival response and the voice data generated by itself to the service server 60. .

  Then, the service server 60 collates the voice data received from the communication terminal 50 with the voice data received from the input device 90 at that time, as in the authentication. If it is determined that the communication terminal 50 is in the service providing area, the communication connection is maintained and the service is continuously provided. On the other hand, when it is determined that the communication terminal 50 is outside the service providing area, the communication connection is cut and the service provision is terminated. As a result, it is possible to stop providing the service to the communication terminal 50 away from the output device 80 after the authentication.

<Main part configuration>
Next, the main configuration of each device included in the service providing system 2 will be described with reference to FIG. FIG. 9 is a block diagram illustrating the main configuration of the communication terminal 50 and the service server 60 included in the service providing system 2.

(Communication terminal 50)
The communication terminal 50 has the same configuration as the communication terminal 10 of the above embodiment.

(Service server 60)
Compared with the service server 20 of FIG. 1, the service server 60 does not include the content transmission unit 211 and the verification target data acquisition unit 212, and the verification unit 214 receives information acquired by the sensor information acquisition unit 213 and performs verification. It is different in the point to do.

  The sensor information acquisition unit 213 (terminal audio acquisition unit, area audio acquisition unit) receives audio data from each of the input device 90 and the communication terminal 50 and transmits the audio data to the verification unit 214. As in the case of the service providing system 1, the sensor information acquisition unit 213 may process the received voice data so that the collation unit 214 can easily collate.

  The collation unit 214 receives the voice data generated by the input device 90 from the sensor information acquisition unit 213 and the voice data generated by the communication terminal 50, and collates the two so that the communication terminal 10 is within the service providing area. To determine. The determination result is transmitted from the collation unit 214 to the service control unit 215. The collation and determination method is as described above.

(Content server 70)
The content server 70 transmits the content data to the output device 80 for output. The function and configuration of the content server 70 are the same as those of the content server 30 of the above embodiment.

(Output device 80)
The output device 80 receives from the content server 70 and outputs it. The function and configuration of the output device 80 are the same as those of the output device 40 of the above embodiment.

(Input device 90)
The input device 90 is a device that acquires sound around the input device 90 as sound data and transmits it to the service server 60. Here, since the input device 90 is disposed in the vicinity of the output device 80, sound data including sound based on the content output from the output device 80 is generated and transmitted to the service server 60.

<Processing operation of service providing system>
Next, the flow of processing in the service providing system 2 will be described with reference to FIG. FIG. 10 is a flowchart illustrating an example of processing (connection control method) in the service providing system 2.

  First, the content server 30 provides content data to the output device 80 (S240). The output device 80 receives the content data (S260) and outputs it (S262).

  The input device 90 constantly acquires the surrounding sound, and generates and acquires sound data based on the sound (S280). The acquired voice data is uploaded to the service server 60 (S282).

  Here, when the user of the communication terminal 50 performs an operation for participating in the service, the communication terminal control unit 110 of the communication terminal 50 generates audio data from the voice around the own device in the communication terminal sensor unit 120. Then, upload to the service server 60 (S200). Further, the communication terminal control unit 110 requests the service server 60 to start a service.

  The sensor information acquisition unit 213 of the service server 60 receives voice data from the input device 90 (S220) and also receives voice data from the communication terminal 50 (S222, terminal voice acquisition step), and collates these voice data. To the unit 214.

  Next, the collation unit 214 determines whether the two audio data received from the sensor information acquisition unit 213 match (S224, determination step), and notifies the service control unit 215 of the result. Note that, as described above, if the waveforms of the audio data match with a certain degree of accuracy, it is determined that they match.

  If a match is notified (YES in S224), the service control unit 215 establishes a communication connection with the communication terminal 50 and starts providing a service (S226, connection control step). Then, the communication terminal 50 receives the service data (S202) and displays it on the display unit 130.

  On the other hand, when it is notified that they do not match (NO in S224), the service control unit 215 determines whether or not a communication connection with the communication terminal 50 is established (S228). In the case of authentication, since the communication connection has not been established yet, it is determined NO in S228, and the process returns to S220 without providing the service to the communication terminal 50. On the other hand, since the communication connection is established after the authentication, the service control unit 215 determines YES in S228, disconnects the communication connection with the communication terminal 50, and ends the service provision (S230).

  Similar to the above embodiment, also in the present embodiment, the communication terminal 50 periodically acquires voice data even after the start of use of the service, and transmits it to the service server 60 (S200). Further, as described above, the input device 90 also periodically acquires voice data (S280) and uploads it to the service server 60 (S282).

  Even if the acquisition timings of both audio data do not completely match, if there is an overlapping part in the acquired time zone, the verification can be successful, but if there is no overlapping part in the time zone, the verification succeeds. There is nothing.

  For this reason, it is desirable that the audio data acquisition / upload timing by the input device 90 and the audio data acquisition / upload timing by the communication terminal 50 be as close as possible. For example, audio data acquisition / upload timing may be designated from the service server 60 to the communication terminal 50 and the input device 90.

<Example of requesting sensor information and sensor device sensor information from service server>
In the flowchart of FIG. 10, an example in which the communication terminal 50 and the input device 90 voluntarily upload audio data is shown, but the service server 60 may request transmission of audio data.

  Hereinafter, the flow of processing when requesting transmission of audio data from the service server 60 will be described with reference to FIG. FIG. 11 is a flowchart illustrating an example of processing when the service providing system 2 requests transmission of audio data from the service server 60. Note that the flow in the figure starts from a state where authentication is successful and the service is provided (communication connection between the service server 60 and the communication terminal 50 is established).

  Similarly to FIG. 10, also in FIG. 11, the content server 30 provides content data to the output device 80 (S340), and the output device 80 receives the content data (S360) and outputs it (S362). ).

  Here, the communication terminal 50 receiving the service requests the service server 60 to transmit service data (S300), and the service server 60 receives this request (S320).

  When the service control unit 215 confirms the reception of the service data request, the service control unit 215 instructs the sensor information acquisition unit 213 to acquire the voice data from the communication terminal 50, and the sensor information acquisition unit 213 transmits the voice to the communication terminal 50 according to the instruction. Data is requested (S322). At this time, a survival response request may be transmitted together.

  In this example, the voice data is requested when the service data transmission is requested, but the timing for requesting the voice data is not particularly limited. For example, it may be requested when data is received from the communication terminal 50, may be requested at regular time intervals, or may be requested at random time intervals.

  When the communication terminal control unit 110 of the communication terminal 50 receives the voice data request from the service server 60, the communication terminal sensor unit 120 acquires the voice data around the own device and uploads it to the service server 60 (S304). . If a survival response request is transmitted in S322, a survival response is transmitted when uploading sensor information.

  When the service control unit 215 of the service server 60 confirms the reception of the voice data (S324), the service control unit 215 instructs the sensor information acquisition unit 213 to acquire the voice data from the input device 90 next. The sensor information acquisition unit 213 requests voice data from the input device 90 according to this instruction (S326). Note that the order of the audio data request to the communication terminal 50 and the audio data request to the input device 90 may be reversed, or these requests may be performed simultaneously.

  When receiving the voice data request from the service server 60, the input device 90 acquires the voice data from the voice around the device (S380) and uploads the voice data to the service server 60 (S382).

  When the service control unit 215 of the service server 60 confirms the reception of the voice data from the input device 90 (S328), the matching unit 214 determines whether the voice data of the communication terminal 50 received in S324 matches the voice data. To instruct.

  The collation unit 214 that has received this instruction acquires both audio data from the sensor information acquisition unit 213, and determines whether they match (S330). This determination method and criteria are as described above.

  When it is determined that they match (YES in S330), the collation unit 214 notifies the service control unit 215 to that effect. In this case, the service control unit 215 maintains the communication connection with the communication terminal 50 and continues to provide the service to the communication terminal 50 (S332), and the communication terminal 50 receives this service via the communication connection. (S306).

  On the other hand, when the collation unit 214 determines that they do not match (NO in S330), the collation unit 214 notifies the service control unit 215 to that effect. In this case, the service control unit 215 disconnects the communication connection with the communication terminal 50, and ends providing the service to the communication terminal 50 (S334).

  As described above, when the service server 60 is configured to request audio data from the communication terminal 50 and the input device 90, the communication terminal 50 and the input device 90 can only receive the audio data when requested by the service server 60. Can be obtained and transmitted. Therefore, according to this configuration, it is possible to reduce the processing load on the communication terminal 50 and the input device 90 as compared with the configuration in which the communication terminal 50 and the input device 90 upload audio data at regular intervals. This is particularly advantageous for the communication terminal 50 that has a high need for power saving.

  Note that the timing of voice data collation is not limited to this example. For example, when the communication terminal 50 moves, the voice data is uploaded from the communication terminal 50, and the voice data is uploaded from the input device 90 at the timing when the voice data is uploaded. Audio data may be acquired and collated. The movement of the communication terminal 50 can be detected by mounting a positioning device such as a GPS receiver on the communication terminal 50.

  Moreover, although the example which uploads audio | voice data from the communication terminal 50 to the service server 60 using the communication connection established between the communication terminal 50 and the service server 60 was shown above, it is not restricted to this example .

  For example, the service server 60 may notify the communication terminal 50 of the voice data transmission destination and transmission method. More specifically, the service control unit 215 may transmit address information of an access destination for resuming the service to the communication terminal 50 when the service provision is started. In this case, when the service is resumed, the communication terminal 50 uses the address information to access the access destination and upload voice data. Then, when the collation unit 214 determines that the communication terminal 50 is within the service providing area, the service control unit 215 of the service server 60 may establish a communication connection and resume service provision.

  As a result, even if the communication terminal 50 ends the service due to being away from the output device 80, the communication terminal 50 can return smoothly to the service providing area and notify the voice data, thereby smoothly restarting without performing authentication again. It becomes possible to do.

  In the example of FIG. 10, both the communication terminal 50 and the input device 90 actively upload voice data, and in the example of FIG. 11, the service server 60 transmits the voice data to both the communication terminal 50 and the input device 90. Although requested, it may be a process that compromises these.

  For example, the communication terminal 50 may actively upload the voice data, and the input device 90 may start uploading the voice data in response to a request from the service server 60. That is, acquisition of audio data from the input device 90 in the example of FIG. 10 may be performed by the processing of S326, S380, S382, and S328 of FIG. In addition, after uploading once, you may make it continue uploading always or at fixed time intervals.

  Similarly, the input device 90 may actively upload voice data, and the communication terminal 50 may start uploading voice data in response to a request from the service server 60. That is, acquisition of audio data from the communication terminal 50 in the example of FIG. 10 may be performed by the processes of S322, S302, S304, and S324 in FIG.

[Embodiment 3]
In the above embodiment, when the communication terminal can acquire the voice output in the service providing area, the communication terminal determines that the communication terminal is in the service providing area and provides the service. However, the method of determining whether or not is in the service providing area is not limited to this.

  In the present embodiment, only a specific area is targeted, and a service is provided depending on whether or not a communication terminal can receive a broadcast that can be received within the area (hereinafter referred to as a regional limited broadcast). An example will be described with reference to FIGS. In addition, the same reference number is attached | subjected to the structure similar to the said embodiment, and the description is abbreviate | omitted.

<Overview of operation>
First, an operation outline of the service providing system according to the present embodiment will be described with reference to FIG. FIG. 12 is a diagram showing an outline of the operation of the service providing system 2 that provides a service to a communication terminal capable of receiving a regional limited broadcast. FIG. 12A shows an operation at the time of authentication, and FIG. ) Shows the operation after authentication.

  The service providing system 3 in FIG. 12 includes a communication terminal 300 and a service server (connection control device, service providing device) 310. The service server 310 and the communication terminal 300 are configured to perform data communication via a network.

  As shown to (a) of the figure, the service server 310 requests | requires notifying the communication terminal 300 of the reception availability of area limited broadcasting. In the illustrated example, since the communication terminal 300 exists in the broadcast area of the regional limited broadcast, the communication terminal 300 notifies the above inquiry that the broadcast can be received.

  Then, the service server 310 that has received the notification that the limited broadcast can be received establishes a communication connection with the communication terminal 300 and starts providing a service via the communication connection. That is, the service server 310 determines that the communication terminal 300 is successfully authenticated when the communication terminal 300 that is to receive the service can receive the area limited broadcast. According to this determination method, the broadcast area of the regional limited broadcast matches the service providing area.

  In addition, after successful authentication, the service server 310 requests the communication terminal 300 receiving the service to notify the reception of the regional limited broadcast. Here, when the communication terminal 300 exists in the broadcast area of the area limited broadcast, a notification that the area limited broadcast can be received is received, and the provision of the service is continued.

  On the other hand, as shown in FIG. 5B, when the communication terminal 300 is out of the broadcast area of the area limited broadcast, a notification that the area limited broadcast cannot be received is received. In this case, the service server 310 disconnects the communication connection with the communication terminal 300 and ends the service provision.

  Thus, according to the service providing system 3, it is possible to provide a service only to the communication terminal 300 in the broadcast area of the regional limited broadcast. As a result, for example, when an event is held in a certain area and a local limited broadcast related to the event is held in the area, it is possible to provide a service only to the participants of the event. Become.

<Main part configuration>
Next, the main configuration of each device included in the service providing system 3 will be described with reference to FIG. FIG. 13 is a block diagram illustrating a main configuration of the communication terminal 300 and the service server 310 included in the service providing system 3.

(Communication terminal 300)
The communication terminal 300 is different from the communication terminal 10 in FIG. 1 in that the communication terminal sensor unit 120 is replaced with the broadcast receiving unit 301. The broadcast receiving unit 301 is for receiving a regional limited broadcast. The area-limited broadcast may be broadcast that can be received only in a specific area. For example, the area-limited broadcast may be a moving image content such as an area-limited one-segment broadcast that can be received only in a specific area. Audio content such as radio broadcasts may be used. The broadcast receiving unit 301 may receive a broadcast wave of a regional limited broadcast, or may receive a regional limited broadcast via a network such as the Internet. In addition, when via a network such as the Internet, for example, the location limited broadcast can be received by transmitting the location information of the communication terminal 300 acquired by a GPS receiver (not shown) to the location limited broadcast transmission server. It is.

  When the communication terminal control unit 110 receives an inquiry as to whether or not the limited area broadcast can be received, it determines whether the broadcast reception unit 301 can receive the limited area broadcast and notifies the service server 310 of the determination result.

(Service server 310)
The service server 310 includes a service server communication unit 200, a service server control unit 210, and a storage unit 220. The service server communication unit 200 includes a service control unit (connection control unit, display control unit) 215 and a reception availability determination unit (reception availability determination unit) 311. In addition to the service data 221, the storage unit 220 stores broadcast designation information 312 indicating a regional limited broadcast that is a criterion for determining whether or not to provide a service.

  The reception availability determination unit 311 determines whether the communication terminal 300 that is to receive the service can receive a predetermined area-limited broadcast. Specifically, when receiving a service provision request from the communication terminal 300, the reception availability determination unit 311 notifies the communication terminal 300 of the availability of the area limited broadcast indicated by the broadcast designation information 312. To request. Then, when a broadcast receivable notification is received in response to this request, the communication terminal 300 determines that it can receive a predetermined area limited broadcast, and when it receives a reception impossible notification, it determines that reception is impossible.

  Note that there may be a plurality of service providing areas of the service server 310. In this case, it is assumed that the broadcast designation information 312 is associated with each service providing area and information indicating a corresponding area-limited broadcast. Then, when the authentication is successful, the service control unit 215 provides a service corresponding to the area limited broadcast used for the authentication.

<Processing operation of service providing system>
Next, the flow of processing in the service providing system 3 will be described with reference to FIG. FIG. 14 is a flowchart illustrating an example of processing (connection control method) in the service providing system 3.

  First, the user of the communication terminal 300 performs an operation for participating in the service. Thereby, the communication terminal control part 110 of the communication terminal 300 transmits a service provision request to the service server 60 (S400).

  Next, when the service control unit 215 of the service server 310 confirms the reception of the service provision request (S420), the service terminal 310 instructs the reception availability determination unit 311 to indicate that the communication terminal 300 requesting service provision is a local area. Determine if limited broadcasts can be received.

  The reception availability determination unit 311 that has received this instruction refers to the broadcast designation information 312 and identifies an area-limited broadcast corresponding to the service requested to be provided. Then, the communication terminal 300 is requested to notify whether or not the specified area-limited broadcast can be received (S422).

  When the communication terminal control unit 110 of the communication terminal 300 confirms the reception of this request (S402), the broadcast reception unit 301 determines whether or not the region-limited broadcast can be received. Then, the service server 310 is notified of the result of this determination (S404).

  Next, the reception availability determination unit 311 of the service server 310 confirms whether or not the notification received from the communication terminal 300 indicates that the area-limited broadcast can be received (S426, reception availability determination). Step). Then, the service control unit 215 is notified of the confirmation result.

  Here, when it is confirmed that notification that reception is possible (YES in S426), the service control unit 215 establishes a communication connection with the communication terminal 300 and starts providing a service (S428, connection control). Step). Then, the communication terminal 300 receives the service data (S406) and displays it on the display unit 130.

  Thereafter, the process of the service server 310 returns to S422. That is, after the service provision is started, the service server 310 periodically requests the communication terminal 300 to transmit the broadcast reception availability, thereby discontinuing the provision of the service to the communication terminal 300 that has left the service provision area. I am doing so.

  On the other hand, if it is confirmed in S426 that the reception is impossible (NO in S426), the service control unit 215 determines whether or not a communication connection with the communication terminal 300 is established (S430). ). In the case of authentication, since the communication connection has not been established yet, it is determined NO in S430, and the process returns to S420 without providing the service to the communication terminal 300. On the other hand, since the communication connection is established after authentication, the service control unit 215 determines YES in S430, disconnects the communication connection with the communication terminal 300, and ends the provision of the service (S432).
