Information 233 and detailed log information 234 exist.

  FIG. 3 is a diagram for explaining a configuration example of the service definition table 217 in the database 106 of the management server 101.

  The service definition table 217 holds information of a management ID 300, a service ID 301, an operation mode 304, a service description area 305, a license key 306, and service specific information 307. The management ID 300 is a number uniquely determined for managing the data of this table, and the service ID 301 is a number for managing the service provided, and corresponds to the service management number 302 for managing the service itself and the service. The service providing application number 303 is associated with the service providing application to be associated. Since a plurality of service providing applications may be used in one service, there are cases where a plurality of applications are registered as this number.

  The operation mode 304 represents the purpose of executing this service. For example, when the service is under development and used for debugging purposes, “1” is used, and the service is actually used for billing purposes. “2”, etc., are designated by symbols so that the system can be easily managed. The value of the operation mode is used to specify which index described in the importance index 605 of the log basic information table 600 described later with reference to FIG. For example, when the operation mode is “1” and the operation 608 of the importance index 605 corresponds to this operation mode, the importance of the data of the management ID 1 in the log basic information management table 600 is determined to be “2”. If the operation mode is “2” and the accounting 607 corresponds to this, the importance of the log information of the management ID 1 is determined to be “1”. The service description area 305 describes an outline of what this service is. The license key area 306 holds license key information necessary for starting the service providing application 238 existing in the interactive display device 141. The license key information is also used when encrypting log information of the service. The service specific information 307 is an area that holds different information for each service.

  FIG. 4 is a diagram illustrating a configuration example of the service management table 218 in the database 106 of the management server 101.

  The service management table 218 holds management ID 400, service ID 401, device number 402, service provision period 403, and status 404 information. The management ID 400 is a number uniquely determined for managing the data of this table. The device number 402 is a device number assigned to each device in order to identify these when there are a plurality of interactive display devices 141. The service provision time 403 records a period during which the service is provided. The status 404 indicates what state this service is currently in, and records, for example, whether the service is being provided, whether the service has been provided, or whether the service has already been provided.

  FIG. 5 is a diagram for explaining a configuration example of the service information 221 in the memory card 110.

  This service information 221 is configured by extracting information necessary for starting up a service in the interactive display device 141 from the service definition table 217 and the service management table 218, and includes a service ID 301, an operation mode 304, and a device number. Each piece of information 402 is held. Note that this information may be encrypted and stored in the memory card 110 in order to protect it from unauthorized access. In this case, for example, it is possible to use a method in which a key to be encrypted is previously incorporated in the management server 101 and the interactive display device 141.

  FIG. 6 is a diagram illustrating a configuration example of a log basic information management table 600 that records a log output by the service providing application 238 during service provision. The log basic information management table 600 is one in the log information table 219 in the database 106.

  The log basic information management table 600 includes the management ID 601, service ID 301, collection date and time 603, collection status 604, charging 607, operation 608, and the like, the importance index 605, the corresponding log detailed information management table 609, and the hash value 613. Hold.

  The management ID 601 is a number uniquely determined for managing the data in this table, and the collection date and time 603 indicates the date and time when this log was collected. The collection status 604 represents the log collection status. For example, there is a status shown as 612 in the lower part of FIG. Details of this will be described later. The importance index 605 is as already described. The correspondence log detailed information management table 609 is information relating to a link indicating which management information of which table of the log detailed information management table 609 is managing the detailed information related to this log, and corresponds to the log detailed information management table 609. The correspondence table name 610 for managing the table name to be managed, and the management ID 611 indicating the corresponding record in the table name 610. The Hash value 613 is a Hash value calculated by concatenating all the values of the log information. For example, the consistency or falsification between the log acquired via the memory card 110 and the log transferred from the interactive display device 141. Used for checking, etc.

  Note that the importance of the log may be determined and set by a person in advance, but the importance index may be automatically determined by determination on the system side. For example, if the characteristics of a program module that outputs log information (such as output of billing information) are registered in advance in the log output module, and these modules output logs, the importance automatically depends on the registered contents Can be used. At this time, the importance level assigned to the log is determined by, for example, ranking the modules with respect to the importance level index 608 specified in the operation mode 304 of the service definition table 217. This rank is set by a person. For example, when the importance index 608 is charged for a certain module, the rank may be set to “2” (the smaller the number, the more important).

  FIG. 7 is a diagram illustrating a configuration example of the log detailed information management table 700. The detailed log information management table 700 is one in the log information table 219 in the database 106. Since this table is prepared for the number of data structures to be managed, it is composed of n tables from table-1 to table-n.

  Each log detailed information management table 700 holds information of management ID 701, registration date 702, and log detailed information 703. The management ID 701 is a number uniquely determined for managing the data of this table. The registration date 702 is the date and time when this information was registered. The log detailed information 703 is an area for managing the detailed information of the log, and the configuration is different for each table. The area of the log detailed information 703 is roughly divided into an area for managing image information 704 and an area for managing information 705 other than images. The reason for this is that image information can be identified simply by reducing the quality of the video itself even if the amount of information is reduced by changing the lossy compression rate, but other text data and binary data include: This is because the lossy compression cannot be applied, and the log information is configured to be easily distinguishable when transmitted to the server.

  FIG. 8 is a diagram for explaining log information 222 generated when a log is stored in the memory card 110 and the interactive display device 141. The log information 222 shown in FIG. 8 has a format in which the contents of the log basic information management table 600 described with reference to FIG. 6 are output to a file. The file itself may be text or binary. In addition, the file itself or a part thereof is encrypted as necessary.

  FIG. 9 is a diagram for explaining the detailed log information 223 generated when the log is stored in the memory card 110 and the interactive display device 141. The log information 223 shown in FIG. 9 has a format in which the contents of the log detailed information management table 700 described with reference to FIG. 7 are output to a file, and a plurality of files exist as in the case of FIG. The file itself may be text or binary. In addition, the file itself or a part thereof is encrypted as necessary.

  FIG. 10 is a diagram for explaining the configuration of log importance management policy information 232 that defines the storage method when log information is stored according to importance.

  As described above, the log importance management policy information 232 exists in the control function unit 144 of the interactive display device 141, and includes a management ID 1000, an importance ID 1001, a network communication speed 1002, a retry count 1007, a display main body. Each of the following information is stored: a log 1008, a log 1009 in the memory card, and an encryption presence / absence 1010.

  The management ID 1000 is a number uniquely determined for managing this data. The importance level ID 1001 corresponds to the numerical value of the importance level recorded in the log basic information management table 600. The network communication speed 1002 is used to switch the log data transfer method to the management server 101 in accordance with the communication speed between the interactive display device 141 and the management server 101. As this switching condition, condition 1 (1004), condition 2 (1005), and condition 3 (1006) are provided, and the communication speed is condition 1 (nMbps or less), condition 2 (nMbps or more and mMbps or less), condition 3 respectively. When (mbps to pMbps), transfer processing according to the transfer condition code 1011 shown at the bottom of FIG. 10 is performed. Note that three or more kinds of conditions may be prepared and further subdivided.

The transfer condition code 1011 is, for example,
A ... Do not transfer logs B ... Transfer only hash values generated from log information C ... Transfer all text, but transfer images with high compression (low image quality) D ... All One of four methods such as transfer of log information completely can be selected.

  In the transfer system exemplified above, network communication conditions become stricter in the order of A, B, C, and D. That is, the transfer method A means that no communication is performed, and the transfer method B means that a large amount of data is transmitted in some cases.

  The retry count 1007 is the maximum retry count when a communication error with the server occurs. When a log is recorded in the display main body 1008, it is specified whether or not to save the log information in the interactive display device 141. Leave log in the memory card 1009 designates whether to leave a log in the memory card 110. The presence / absence of encryption 1010 designates whether or not the corresponding importance data is to be encrypted. Note that the key information for encryption may be the license key 306 shown in FIG. 3, for example. By using this license key 306, the log information can be encrypted differently for each service. For example, it is restricted that other service personnel peek at information related to a specific service. In the worst case, even if the license key 306 is stolen, only the log of the service corresponding to the license key 306 is compromised.

  FIG. 11 is a flowchart for explaining a basic processing operation for providing a service using the system according to the embodiment of the present invention. Next, this will be explained.

(1) The person in charge 1102 of the display installation location 140 such as a hotel examines the service to be introduced into the event venue 150 and, after determining the service to be introduced, informs the person in charge 1101 of the service providing company 100 of the information on the service to be introduced To do. This contact may be made via the management terminal 102 of the service provider or by telephone (steps 1103 and 1104).

(7) When the provision of the service is completed, the person in charge 1102 of the display installation location 140 turns off the interactive display device 141 and takes out the memory card 110. Then, the memory card 110 is sent to the person in charge 1101 of the service providing company 100 by mail or the like (steps 1115 and 1116).

(8) Upon receiving the memory card 110, the person in charge 1101 of the service providing company 100 sets the memory card 101 to the management terminal 102 and transmits the log information stored in the memory card 110 to the administrator server 101 ( Steps 1117, 1118).

(9) The management server 101 retrieves the Hash value of the corresponding log information from the basic information management table 600 for the portion of the received log information for which the Hash value has been transmitted in advance and collates it, and found falsification If so, check that. If there is no falsification, the log information is stored in the log basic information management table 600 and the log detailed information management table 700 (step 1119).

(10) The management server transmits the processing result in step 1119 to the management terminal 102 including the presence or absence of falsification, and then performs the accounting process. Details of the billing process will be described later (steps 1120 and 1121).

  FIG. 12 is a flowchart for explaining the detailed processing operation of system activation in step 1113 of FIG. 11. Next, this will be described.

(1) When the interactive display device 141 is activated, the interactive display device 141 reads the service information 221 from the memory card 110 and decodes it. At this time, as described above, a method using public key encryption or common key encryption is used (steps 1200 and 1201).

(2) Then, the interactive display device 141 activates the service providing application 238 corresponding to the extracted service information 221, and then checks the state of the network with the management server 101, and if interactive, the interactive display device The service information is transmitted to the management server 101 in order to notify that 141 has started (steps 1202 to 1204).

(3) Upon receiving the service information from the interactive display device 141, the management server 101 records the system activation in a log (step 1212).

(4) After that, the interactive display device 141 checks whether or not a cooperation function with the management server 101 exists. If the cooperation function with the management server 101 does not exist, the interactive display apparatus 141 ends the activation process (step 1205).

(5) If the link function with the management server 101 exists in the check in step 1205, the interactive display device 141 checks whether the quality of the network is sufficient to operate in cooperation with the link function ( Step 1206).

(6) If the quality of the network is below the standard in the check in step 1206, the interactive display device 141 checks whether there is an alternative function when it is difficult to connect to the management server, and there should be no alternative function. If this is the case, the system startup process is terminated (step 1207).

(7) If there is a substitute function that can be used even if the quality of the network is below the standard in the check in step 1206, the substitute function is activated. It should be noted that the standard for this alternative function is desirably a level at which the quality of service does not deteriorate from the user's point of view even if there are operational limitations (step 1208).

(8) On the other hand, if the network quality is above the standard in the check in step 1206, the interactive display device 141 instructs the management server 101 to start the system cooperation function (step 1209).
(9) Receiving the instruction to start the system cooperation function, the management server 101 starts the cooperation function and notifies the interactive display device 141 of the start completion (steps 1210 and 1211).

  Note that the network quality standards necessary for the above-described cooperative operation depend on the application, and thus cannot be generally specified. However, if the management server 101 can monitor the operation of the interactive display device 141, the communication speed is several. The transmission speed may be about 100 kbps. If video or the like is transmitted, a communication speed of several Mbps is required.

  FIG. 13 is a flowchart for explaining the detailed processing operation of the system operation and log output in step 1114 of FIG. 11, which will be described next.

(1) The service providing application 238 of the interactive display device 141 operates in cooperation with the service providing application cooperation unit of the management server 101 in some cases. At this time, when an event such as a user operation occurs on the interactive display device 141, the service providing application 238 outputs a log (steps 1300 and 1301).

(2) Since the output log includes importance level information, the interactive display device 141 checks the importance level index in the log from the current operation mode and determines the current importance level of the log. Determine (steps 1302, 1303).

(3) After that, the interactive display device 141 searches the record of the corresponding importance in the log importance management policy information 232 and starts the processing in order to perform various processes according to the importance (step 1304).

(4) Then, the interactive display device 141 first checks whether or not the data is encrypted. If the data is not encrypted, nothing is performed. If the data is encrypted, it is included in the service information. Encryption is performed using the license key as an encryption key (steps 1305 and 1306).

(5) Next, the interactive display device 141 checks whether there is an instruction to leave a log in the main body of the display device 141. If there is an instruction, the interactive display device 141 logs in the display device 141. Is stored (steps 1307 and 1308).

(6) Next, the interactive display device 141 checks whether or not there is an instruction to leave a log in the memory card 110. If there is an instruction, the interactive display apparatus 141 does not do anything. The log is stored (steps 1309 and 1310).

(7) Thereafter, a conditional log transfer process is performed. Details of the conditional log transfer process will be described later (step 1311).

(8) The log output process is completed. Thereafter, the interactive display device 141 determines whether or not the system is terminated. If not terminated, the interactive display apparatus 141 returns to the processing from step 1300 and continues the operation, and if terminated, notifies the management server 101 of the system termination (step 1312, 1313).

(9) The management server 101 records the system end in a log, and then checks whether the management server cooperation function is operating. If it is operating, the management server 101 stops the cooperation function and ends the service ( Steps 1317-1319).

(10) On the other hand, if it is determined in step 1312 that the system is terminated, the interactive display device 141 checks whether the management server cooperation function is used, and if it is used, checks whether the alternative function is being used. If it is in use, the alternative function is stopped and the system is terminated (steps 1314 to 1316).

  FIG. 14 is a flowchart for explaining the processing operation of conditional log transfer in step 1311 of FIG. 13, which will be described next.

(1) The interactive display device 141 checks the communication speed x Mbps of the current network, and as a result of this check, whether or not the communication speed x Mbps satisfies the condition 1 of the network communication speed 1002 of the log importance management policy information 232, Kanagawa,
xMbps ≦ nMbps
Is checked (steps 1402, 1403).

(2) If the communication speed x Mbps satisfies the condition 1 of the network communication speed 1002 of the log importance management policy information 232 in the check in step 1403, the value specified in the condition 1 is acquired and the value is The conditional log transfer process is performed and the process ends (steps 1404 and 1405).

(3) If it is determined in step 1403 that the condition 1 is not satisfied, the processes for the condition 2 and the condition 3 are performed as described above (steps 1406, 1407, 1405, 1409, 1410, 1405).

  In the above description, as a method for measuring the communication speed, for example, a huge file (about several tens of Mbytes) is transferred from the interactive display device 141 to the management server 101, and a transfer end notification is sent from the management server to the interactive display after the transfer ends. Since the time taken for the transfer can be determined by notifying the device 141, the transfer speed can be obtained by the following equation (1).

File size (bytes) / transfer time (s) = transfer speed (bps) (1)
When the transfer rate obtained by Expression (1) is equal to or less than the above-described reference value, it is determined that the cooperative operation cannot be performed.

  FIG. 15 is a flowchart for explaining the processing operation of the detailed conditional log transfer processing in step 1405 of FIG. 14, which will be described next.

(1) The interactive display device 141 first sets the error retry count value (ER) with reference to the log importance management policy information 232, then acquires the value of the condition value of the network communication speed 1002, and sets the condition It is determined whether or not value = A. If condition value = A holds, the process is terminated because no transfer is performed (steps 1500 and 1501).

(2) If the condition value = A is not satisfied in the determination in step 1501, that is, if the condition value is different from A, the hash value is calculated from the log, and it is determined whether or not the condition value = B. . When the condition value = B holds, the service information and the Hash value are transmitted to the management server 101, and the process proceeds to step 1511 described later (steps 1502-1504).

(3) If the condition value = B does not hold in the determination in step 1503, that is, if the condition value ≠ B, it is determined whether or not the condition value = C. If the condition value = C holds, log The amount of data is reduced by increasing the compression rate of image data existing in the server, service information, non-image information of logs, generated image data, and hash values are transmitted to the management server 101, and the process proceeds to step 1511 described later. (Steps 1505 to 1507).

(4) If the condition value = C is not satisfied in the determination in step 1505, that is, if all the conditional expressions are different, it is determined that the condition value = D, and all the log information and the hash value are transferred to the management server 101. Transmit (step 1508).

(5) Then, the management server 101 registers the data transmitted from the interactive display device 141 in step 1504, 1507 or 1508 as log information, and notifies the interactive display device 141 of the processing result (steps 1509 and 1510). .

(6) The interactive display device 141 checks whether or not a transfer error has occurred based on the processing result from the management server 101. If no error has occurred, the interactive display device 141 ends the process (step 1511).

(7) If an error has occurred in the check at step 1511, the error retry counter is decremented by “1”, and if it is not “0”, the process returns from step 1501 to execute the process again. When “0” is reached, a transfer error is recorded and the process is terminated (steps 1512 to 1514).

  FIG. 16 is a flowchart for explaining the processing operation of the billing process in step 1121 of FIG. 11. Next, this will be described.

(1) The person in charge 1101 of the service providing company 100 confirms the log contents. As this confirmation content, for example, there is a check such as data tampering (step 1600).

(2) Thereafter, the person in charge 1101 of the service providing company 100 aggregates information for billing, and informs the person in charge 1102 of the display installation location 140 of the usage fee based on the aggregation result (steps 1601 and 1602).

(3) Then, the person in charge 1102 of the display installation location 140 notifies the service user 1102 of the received usage fee (step 1603).

(4) After confirming the contents, the service user 1102 pays the usage fee to the person in charge 1102 of the display installation location 140 (steps 1604 and 1605).

(5) The person in charge 1102 of the display installation location 140 collects a fee and pays the system usage fee to the person in charge 1101 of the service providing company 100 (steps 1606 and 1607).

(6) After that, the person in charge 1101 of the service provider performs billing processing such as summing up the collected results (step 1608).
