It is transmitted and the audio data is stored.

  The configuration of the information management system of the present invention will be described.

  FIG. 1 is a block diagram showing an example of the configuration of the information management system of the present invention.

  As shown in FIG. 1, an information management system provided on an ASP (Application Service Provider) side provides a VoIP (Voice over Internet Protocol) function between a distributed server 10 that stores data as grid computing and an information terminal. An IP Centrex server 20, a center server 30 that manages voice data and document data to be recorded, an electronic signature & time stamp server (hereinafter referred to as a stamp server) 50 for issuing a certificate, and a Web server 40. It is the composition which has.

  Each server is connected via a LAN (Local Area Network) 80. The LAN 80 is connected via the Internet 90 to IP telephone terminals 60a and 60b and personal computers (hereinafter referred to as PCs) 70a and 70b on the user side. Since the IP telephone terminal 60a and the IP telephone terminal 60b on the user side have the same configuration, the case of the IP telephone terminal 60a will be described below. Since the PC 70a and the PC 70b have the same configuration, the case of the PC 70a will be described below. Further, hereinafter, the LAN 80, the Internet 90, and the like are referred to as a network.

  The distributed server 10 is connected to a plurality of distributed databases 12 for storing document data and audio data, and functions as grid computing that integrates these distributed databases 12 into one. The distributed database 12 is for storing various data. The distributed server 10 then manages which data is stored in which address of the plurality of distributed databases 12 and notifies the center server 30 of storage information indicating storage destination addresses for various data.

  The IP center server 20 controls the routing of voice data between the IP telephone terminal and the PC. Here, the routing control of the IP Centrex server 20 will be briefly described below. It is assumed that each of the two users makes a call using the IP phone terminal 60a and the IP phone terminal 60b.

  When the IP telephone terminal 60a captures voice with a microphone, it converts it into voice data of a digital signal, and divides the voice data into predetermined units. Subsequently, a header is added to the divided audio data to form a packet, and a plurality of packets are sequentially sent to the IP Centrex server 20. The header includes IP address information that is an identifier different for each information terminal such as an IP telephone terminal and a PC. There are two types of IP addresses included in the header: a source IP address and a destination IP address. In this case, the transmission source is the IP telephone terminal 60a, and the transmission destination is the IP telephone terminal 60b. When receiving the packet, the IP Centrex server 20 reads the destination IP address and transmits the packet to the IP telephone terminal 60b. When the IP telephone terminal 60b sequentially receives a plurality of packets from the IP Centrex server 20, the IP telephone terminal 60b joins the audio data included in the packets and outputs the audio from the speaker. On the contrary, when sending voice data from the IP telephone terminal 60b to the IP telephone terminal 60a, the IP address of the transmission destination and the transmission source included in the header are switched, and the IP Centrex server 20 sends the packet to the IP telephone terminals 60b to 60a. Send. Note that a compression technique may be used in order to reduce the amount of information of audio data to be placed in the packet.

  In this embodiment, when the IP Centrex server 20 receives a signal from the center server 30 requesting a packet including a predetermined IP address in the header, at least one of the transmission source IP address and the transmission destination IP address in the header. When one of the packets having a predetermined IP address is received from the outside, the packet is transmitted to the destination IP address as described above, and a copy of the packet is transmitted to the center server 30.

  Next, the configuration of the center server 30 will be described.

  FIG. 2 is a block diagram illustrating a configuration example of the center server.

  The center server 30 is an information processing apparatus including a storage unit 31, a data transmission / reception unit 32 that transmits / receives information to / from the outside, and a control unit 33 that controls each unit. The storage unit 31 stores in advance PJ management application software (hereinafter referred to as PJ management software) for managing the data of each project with a PJ number that is a management number different for each project. The PJ includes information such as storage information received from the distributed server 10, a registration file for storing user information of a user who uses the PJ management software, a PJ name, a PJ related person name, and a data-by-data disclosure level. Management information is stored. The control unit 33 includes a CPU (Central Processing Unit) 34 that executes a predetermined process according to a program, and a memory 35 that stores the program. The program stored in the memory 35 is for the CPU 34 to execute in cooperation with the processing of the PC by the PJ management software downloaded to the PC.

  When an instruction to record voice data and IP address information are input, the center server 30 requests the IP Centrex server 20 for a packet including the IP address information in the header. Is stored in the distributed server 10. When a PJ number is input together with an instruction to record, voice data is stored in the distributed server 10 for each PJ number. On the other hand, when an instruction to record the document data is input, the document data is stored in the distributed server 10. If a PJ number is attached, the same processing as for audio data is performed.

  In both cases of audio data and document data, after storing the data, a signal for requesting a data certificate is transmitted to the stamp server 50, and the certificate and data for certifying the data are sent. When stamp data including registration date information is received, it is attached to the data stored in the distributed server 10. Further, an address indicating the data storage destination, a record relating to the data, and a signal requesting the disclosure of the record are transmitted to the Web server 40.

  Next, the configuration of the stamp server 50 and the Web server will be described.

  When the stamp server 50 receives a signal requesting a data certificate, the stamp server 50 transmits the stamp data to the request source.

  When the Web server 40 receives an address indicating the storage location of the data, a record related to the data, and a signal requesting the disclosure of the record, the Web server 40 posts the record on the Web page. When receiving a signal requesting recording data posted on the Web page, the address information is provided to the request source. The Web server 40 requests information such as a user ID and a password from the information terminal that requests access, rejects access from an information terminal that does not match the previously registered user ID and password, and is irrelevant to the project. People cannot see web pages.

  Next, the configuration of the PC 70a will be described.

  The PC 70a includes a terminal storage unit for storing information downloaded from various servers, a data transmission / reception unit for transmitting / receiving information via the Internet 90, a display unit, a terminal control unit for controlling each unit, and a user Has an operation unit for inputting instructions. The operation unit includes a mouse for moving a pointer on a screen serving as a display unit and a keyboard for inputting characters. The PC 70a stores a program for making a telephone call as an IP phone in advance, and functions as an IP phone by connecting a receiver and a microphone to the operation unit.

  Here, an operation screen when the terminal control unit of the PC 70a executes the PJ management software will be described. When the terminal control unit of the PC 70a executes the PJ management software, the PJ list is displayed on the screen. In the PJ list, PJ names are listed in order for each project, and a PJ button for moving to the PJ page is displayed beside each PJ name. When the user operates the mouse to move the pointer over the PJ button and clicks, a browse button for calling information recorded on the PJ on another screen, and a record button for newly recording information Is displayed. Further, when the user operates the mouse to select a recording button, a recording screen on which “IP phone call”, “PC call”, and “document” buttons are displayed.

  Next, the operation of the PC 70a by the operation on the above screen will be described. When the user operates the mouse on the recording screen and selects “call by IP phone”, the terminal control unit sends a recording request signal to the center server 30 for requesting recording of voice data of the call by the IP phone terminal 60a.

  Further, when the user operates the mouse to select the browse button on the screen on which the browse button and the record button are displayed, the terminal control unit transmits a browse page request signal indicating that a browse page is requested to the Web server 40. .

  Next, a registration method for the user to use the PJ management software in the information management system configured as described above will be described.

  When the user operates the PC 70a to input an instruction to request a registration file for user registration, the PC 70a transmits a file request signal indicating that a registration file is requested to the center server 30. When the center server 30 receives the file request signal from the PC 70a, the center server 30 transmits the registered file to the PC 70a. The PC 70a displays the registration file received from the center server 30 on the screen. When the user operates the PC 70a to input user information, the PC 70a transmits the file in which the user information is entered to the center server 30.

  The center server 30 performs user registration by storing the registration file received from the PC 70 a in the storage unit 31. Subsequently, the PJ management software is downloaded to the PC 70a. The PC 70a stores the PJ management software received from the center server 30 in the storage unit.

  Next, a procedure for enabling data recording on the user's PC 70a will be described.

  In order to register the PJ management information such as the PJ name, the PJ related person name, and the data-by-data disclosure level in the center server 30, the user operates the PC 70a to execute the PJ management software and inputs the PJ management information. The PC 70 a transmits the input PJ management information to the center server 30. When the center server 30 receives the PJ management information from the PC 70 a, the center server 30 registers the PJ management information in the storage unit 31. Thereafter, the PJ name is read from the PJ management information, and a button display permission signal including information indicating that the PJ name and a button for starting data storage are displayed is transmitted to the PC 70a.

  When receiving the button display permission signal from the center server 30, the PC 70a sets the PJ button, which is a button displaying the PJ name included in the button display permission signal, to be displayed on the PJ list on the screen.

  Next, an operation procedure in which the information management system stores voice will be described.

  FIG. 3 is a flowchart showing an operation procedure for storing audio data by the information management system. Note that the communication processing between the IP telephone terminal 60a and the other party's telephone terminal is the same as in the prior art, and thus detailed description of the operations of the IP telephone terminal 60a and the IP Centrex server 20 is omitted.

  Before the user starts a call to be recorded on the IP telephone terminal 60a, the PC 70a is caused to execute PJ management software. After the PC 70a displays the operation screen, the user operates the mouse to click the PJ button on which the target PJ name is displayed from the PJ list displayed on the screen, and then the recording screen is displayed. When “IP phone call” is selected, the PC 70a transmits a recording request signal to the center server 30 (step S1).

  When the center server 30 receives the recording request signal from the PC 70a, the center server 30 transmits an IP address included in the recording request signal and a packet including information on the IP address in the header to the center server 30 in addition to the destination telephone terminal. Routing instruction information to that effect is transmitted to the IP Centrex server 20 (step S2). When receiving the routing instruction information and the IP address from the center server 30, the IP Centrex server 20 saves the packet, transmits a packet including the IP address information in the header to the telephone terminal of the other party, and sends the packet to the center server 30. Control voice traffic to transmit.

  When the user starts a call using the IP telephone terminal 60a, the IP telephone terminal 60a transmits a packet including an IP address and voice data to the IP Centrex server 20 (step S3). The IP Centrex server 20 transmits the packet received from the IP phone terminal 60a to the destination phone terminal and the center server 30 (step S4). When the center server 30 receives the packet including the IP address information of the IP telephone terminal 60a, the center server 30 assigns a PJ number to the packet and transmits the packet to the distributed server 10 (step S5). When receiving the packet from the center server 30, the distributed server 10 stores the voice data of the packet for each PJ number assigned to the packet (step S6).

  When the user ends the call and places the handset of IP telephone terminal 60a, IP telephone terminal 60a transmits a session end signal for notifying the end of communication to IP Centrex server 20 (step S7). When receiving the session end signal from IP telephone terminal 60a, IP Centrex server 20 transmits the session end signal to the destination telephone terminal and center server 30 (step S8). The center server 30 transfers the received session end signal to the distributed server 10 (step S9). When the distributed server 10 receives the session end signal from the center server 30, the distributed server 10 stores the plurality of audio data stored during the call together in order of time (step S10).

  Next, an operation procedure for enabling the information management system to issue a certificate for voice data and to call the voice data on a web page will be described.

  FIG. 4 is a flowchart showing an operation procedure for issuing an audio data certificate and making it callable on a web page by the information management system.

  The distributed server 10 transmits the PJ number, the stored information, and the call record such as the call date and time to the center server 30 (step S11). When the center server 30 receives the PJ number, the stored information, and the call record from the distributed server 10, the center server 30 transmits a stamp request signal indicating that the stamp data is requested to the stamp server 50 (step S12).

  Upon receiving the stamp request signal from the center server 30, the stamp server 50 transmits stamp data to the center server 30 (step S13). The center server 30 assigns a PJ number to the stamp data received from the stamp server 50 and transmits it to the distributed server 10 (step S14). When the distributed server 10 receives the stamp data to which the PJ number is attached from the center server 30, the distributed server 10 stores the stamp data together with the voice data specified by the PJ number (step S15). The distributed server 10 transmits the address storing the voice data, the PJ number, and the call record to the center server 30 (step S16).

  The center server 30 transmits to the web server 40 the address, PJ number and call record received from the distributed server 10, and a signal to request posting on the web page (step S17). The Web server 40 stores the address, PJ number, and call record received from the center server 30. Subsequently, together with the received PJ number and call record, a button for transmitting address information to the PC 70a when selected is displayed on the Web page (step S18).

  Next, an operation procedure for storing a document by the information management system will be described. Assume that a file created by a document creation application and a document file such as a mail document are recorded.

  FIG. 5 is a flowchart showing an operation procedure for storing a document by the information management system.

  When the user operates the PC 70a to cause the PC 70a to execute the PJ management software, the PC 70a displays the PJ list on the screen. The user operates the mouse to select the PJ button of the PJ name to be recorded, and displays the recording screen. Subsequently, when the user operates the mouse to drag the icon of the document file to be recorded and move it to the “document” position, and then drop it, the PC 70a attaches the PJ number to the document file and the center server 30. (Step S31). The document file includes document management number and document file name information in addition to the document content.

  When the center server 30 receives the document file together with the PJ number from the PC 70a, the center server 30 checks the free capacity of the distributed server 10 from the existing storage information stored in the storage unit 31, and follows the predetermined procedure to determine the received document file. Determine the destination address. Subsequently, the storage information indicating the address and the PJ number are attached to the document file and transmitted to the distributed server 10 (step S32). When the distributed server 10 receives the storage information, PJ number, and document file from the center server 30, the distribution server 10 stores the PJ number and document file at the address of the distributed database 12 indicated by the storage information in order to register the document file (step S33). ).

  Next, an operation procedure in which the information management system issues a certificate to a document file and enables the document file to be read on a web page will be described. Here, the document file is an e-mail. The operation procedure of the information management system is the same as the flowchart described with reference to FIG. 4 and will be described with reference to FIG.

  The distributed server 10 transmits information on the PJ number, document file registration date and time, mail sender name and receiver name to the center server 30 (step S11). When the center server 30 receives the information of the PJ number, registration date / time, mail sender name and receiver name from the distributed server 10, the center server 30 transmits a stamp request signal to the stamp server 50 (step S12).

  Upon receiving the stamp request signal from the center server 30, the stamp server 50 transmits stamp data to the center server 30 (step S13). The center server 30 assigns a PJ number to the stamp data received from the stamp server 50 and transmits it to the distributed server 10 (step S14). When the distributed server 10 receives the stamp data with the PJ number attached from the center server 30, the distributed server 10 stores the stamp data together with the document file specified by the PJ number (step S15). The distributed server 10 transmits information on the address storing the document file, PJ number, registration date and time, mail sender name and receiver name information to the center server 30 (step S16).

  The center server 30 transmits the address received from the distributed server 10, the PJ number, the registration date and time, the information of the sender name and receiver name of the mail, and a signal to request posting on the Web page to the Web server 40. (Step S17). When the Web server 40 receives information on the address, PJ number, registration date / time, mail sender name and receiver name from the center server 30, the Web server 40 stores these information. Subsequently, together with the received PJ number, document file name, and registration date and time, a button for transmitting address information to the PC 70a when displayed is displayed on the Web page (step S18). The items posted on the Web page are not limited to the PJ number, the document file name, and the registration date and time, but may include a mail sender name and a recipient name. Moreover, you may decide beforehand the item to publish among these items.

  Next, a method for a user to call PJ information in the distributed database 12 will be described. Here, it is assumed that voice data for telephone exchange is called.

  FIG. 6 is a flowchart showing an operation procedure of the PC for calling up voice data.

  When the user operates the PC 70a to cause the PC 70a to execute the PJ management software, the PC 70a displays a PJ list. When the user operates the mouse to select a PJ button of a project to be called from the PJ list, and then selects a browse button, the PC 70a transmits a browse page request signal to the Web server 40 (step S61). When receiving the browse page request signal from the PC 70a, the Web server 40 transmits the browse page to the PC 70a (step S62). The PC 70a displays the browse page received from the Web server 40 on the screen.

  On the browsing page, voice data and document data are collected for each PJ number, and a call record is displayed in the voice data. If the document data is an electronic mail, the document file name and registration date and time are displayed. Each data has a button for calling the data.

  When the user operates the mouse to move the pointer to the button of the audio data that the user wants to call and clicks, the PC 70a receives the address information as the storage destination of the audio data from the Web server 40 and receives the audio information including the address information. A voice data request signal indicating that data is requested is transmitted to the distributed server 10 (step S63).

  When receiving the voice data request signal from the PC 70a, the distributed server 10 transmits the voice data at the address included in the voice data request signal to the PC 70a (step S64). When receiving the audio data from the distributed server 10, the PC 70a stores the audio data so that the audio can be reproduced, and displays an operation screen for inputting an audio reproduction instruction (step S65).

  Next, a case where an e-mail is called as document data will be described. Note that until the browsing page is displayed on the PC 70a, the detailed description thereof is omitted because it is the same as the case of calling the voice data.

  After the PC 70a displays the browsing page, when the user moves the pointer to the button of the document data that the user wants to call by operating the mouse and clicks, the PC 70a receives the information of the address where the document data is stored from the Web server 40. Then, a document data request signal indicating that the document data is requested including the address information is transmitted to the distributed server 10.

  When receiving the document data request signal from the PC 70a, the distributed server 10 transmits the document data at the address included in the document data request signal to the PC 70a. When the PC 70a receives the document data from the distributed server 10, the PC 70a displays the document data on the screen.

  In the present invention, as described above, voice data transmitted / received by an information terminal such as the IP telephone terminal 60a to / from another information terminal is also transmitted to the center server 30 and stored in the distributed server 10 for recording. Therefore, after the user makes a call using the IP phone terminal 60a, the user does not need to create a document for recording the call content, and an e-mail attached with the document recording the call content is sent to the project member. There is no need to send it to everyone. Thereby, the user can reduce the labor for information sharing compared to the related art.

  Further, if document data and audio data are stored with a PJ number, the data is stored for each management number. Therefore, by using the PJ number as a search condition, the user can easily call up data of his / her project.

  If a certificate is issued for the stored data and the registration time is stored together with the certificate, it is possible to prove that the data is original by issuing the certificate and recording the registration date and time.

  In addition, the information management system not only manages voice data and document data in a batch, but also displays a record of stored documents and call contents to the user in a list of web pages, and the user starts from the displayed record.
