The electrical appliance 10 is assumed to include a computer, but may be an electrical appliance belonging to a household electrical appliance or a commercial electrical appliance as long as the electrical appliance 10 includes the above-described configuration.

[First identification processing]
FIG. 3 is a flowchart of first identification processing executed by the information processing device 50, the identification server 300, and the investigation information processing device 60. As a premise, the request packet transmission unit 54, the response packet reception unit 55, the definition file storage unit 56, the scoring unit 57, and the appliance type determination unit 58 of the information processing apparatus 50 execute the type determination process of FIG. The type of the electrical appliance 10 is determined. That is, when the type of the electrical appliance 10 is determined, the device identification of the predetermined electrical appliance 10 is completed. Here, the determination of the type of the electrical appliance 10 means that the type of the electrical appliance 10 (manufacturer name or model name (or one of these)) is determined.

  In this device identification process, there may be an electrical appliance 10 whose type is not determined among the electrical appliances 10. For example, since the electrical appliance 10 is a new product, the information processing apparatus 50 cannot perform device identification when there is no dictionary data (definition file) for determining the type of the electrical appliance 10. In this case, the unidentified determining means 51 of the information processing apparatus 50 determines that the electrical appliance 10 is unidentified (step S10). The determination as to whether or not the electrical appliance 10 is unidentified may be, for example, determined as unidentified if it is equal to or less than a predetermined point in a scoring process to be described later. If the name cannot be determined, it may be determined that the name has not been identified.

  As shown in FIG. 4, the detection data includes a series of request packets and response packets (response data) for the request packets.

  The dictionary data is data in which detection data including a series of request packets and response packets is associated with the type of the electrical appliance 10 in advance.

  When the unidentified determination means 51 determines that the electrical appliance 10 is unidentified (step S10: “YES”), the process proceeds to step S11, and when the electrical appliance 10 is not determined to be unidentified (step S10: “NO”) loops the process. Next, a series of request packets and response packets transmitted / received to / from the information processing apparatus 50 by the electrical appliance 10 that cannot identify the device is determined as investigation-required data, and the investigation-required data is transmitted to the identification server 300 (step S11). .

  Next, the identification server 300 receives the investigation required data and determines whether or not the device has been identified by referring to the dictionary data (definition file) stored in the identification server (step S12).

  The processing of the identification server 300 will be described with reference to FIG. As an example, as illustrated in the detection data 1, when the information processing apparatus 50 transmits a packet A as a request packet, a packet 01 is returned from the electrical appliance 10-a as a response packet and a packet B is transmitted. When a packet of 02 is returned as a response packet, this series of data becomes the detection data 1.

  If the detection data 1 cannot be identified by the information processing apparatus 50, the information processing apparatus 50 transmits the detection data 1 as investigation required data to the identification server 300. The identification server 300 compares the detection data 1 with the dictionary data (definition file) stored in the information processing apparatus 50, performs scoring, and determines that the device name of the electrical appliance 10-a is “AB-01”. To do. In this case, the server device identification unit 303 of the identification server 300 determines that device identification has been completed (step S12: “YES”). In this case, the identification server 300 transmits the result of device identification to the information processing apparatus 50 as device data, and the processing is completed by performing device identification.

  On the other hand, as shown in the detection data 2, for example, when the information processing apparatus 50 transmits a packet A as a request packet, a packet Z is returned from the electrical appliance 10-b as a response packet, and the packet B is When transmitted, when a packet of Y is returned as a response packet, this series of data becomes the detection data 2.

  If the detection data 2 cannot be identified by the information processing apparatus 50, the investigation data determining means (not shown) of the information processing apparatus 50 transmits the detection data 2 as the investigation required data to the identification server 300. . The identification server 300 compares the detection data 2 with the dictionary data (definition file) stored in the identification server 300, but since there is no dictionary data (definition file) corresponding to the identification server 300, the appliance 10-b The device name is not determined, and the device name is “Unknown”.

  In this case, the server device identification unit 303 of the identification server 300 determines that the device could not be identified (step S12: “NO”), and the investigation command unit 306 of the identification server 300 uses the detected data 2 as the investigation required data. To the information processing device 60 for investigation.

  Next, the investigation required data receiving means 65 of the investigation information processing apparatus 60 receives the investigation required data transmitted from the identification server 300 (step S13).

  The detection data receiving means 66 of the investigation information processing device 60 transmits a series of request packets constituted by the investigation required data to the connected investigation electrical appliance 12 to obtain a response packet (step S14). ). Detection data is formed by response packets to the series of request packets. Then, the comparison means 67 of the investigation information processing apparatus 60 compares the investigation required data with the received detection data (step S15). Then, the unidentified device identifying means 68 of the investigation information processing apparatus 60 determines that the detected data is the same, substantially the same as or similar to the investigation required data (similar criteria will be described later), and a series of response packets. The manufacturer name and model name are determined according to the type of electrical appliance of the investigation electrical appliance 12 that has received the message, and the device is identified (step S16).

  Here, the types of electrical appliances of the investigation electrical appliance 12 are investigated by associating the types of electrical appliances with the detection data because the manufacturer name or model name is specified in advance by the administrator of the research company. Information processing device 60.

  Note that the detection data receiving means 66 of the investigation information processing device 60 does not need to transmit a predetermined request packet to each investigation electrical appliance 12 for the first time at the time when the investigation required data is received from the identification server 300. That is, at the timing when the investigation electrical appliance 12 is connected to the investigation information processing apparatus 60, the detection data is acquired and stored in the investigation information processing apparatus 60 in advance. Then, at the timing when the investigation required data is received from the identification server 300, the detected data is compared with the investigation required data, and it is determined whether or not the investigation electrical appliance 12 that is determined to be the same or similar exists. To do. Then, if it exists, the type of electrical appliance is determined by the electrical appliance for investigation 12, and if it does not exist, a predetermined request packet is transmitted to each electrical appliance for investigation 12, and after step S14 Processing may be executed.

  Next, the unidentified device identification means 68 of the investigation information processing apparatus 60 transmits the device data to the identification server 300 using the identified type of appliance as device data (step S17). The identification server 300 receives the device identification data, and stores the detected data and the model name in association with each other as dictionary data. And the identification server 300 transmits apparatus data to the information processing apparatus 50 (step S18). Then, the device data receiving means 52 of the information processing apparatus 50 receives and stores the device data (step S19). Thereby, the type of the appliance 10 that has not been identified in the information processing apparatus 50 can be identified.

  As a modified example of the first identification process, the identification server 1 is not provided with the identification server 300, and the investigation required data is directly transmitted from the information processing apparatus 50 to the investigation information processing apparatus 60, and the processes after step S13 are performed. The survey information processing apparatus 60 may execute the process.

[Second identification process (SaaS type)]
Next, FIG. 5 will be described in order to explain the second identification process (see FIG. 6). FIG. 5 is a functional block diagram of the information processing apparatus 50, the investigation information processing apparatus 60, and the identification server 300. Unlike the first identification process, the second identification process is different in that the identification server 300 identifies an unidentified device of the appliance 10.

  The information processing apparatus 50, the investigation information processing apparatus 60, the identification server 300, the electrical appliance 10, and the electrical appliance 12 may have the same hardware configuration as that of the first identification process.

  The information processing apparatus 50 realizes the detection data transmission unit 53 and the device data reception unit 59 by the above-described hardware alone or in cooperation.

  The investigation information processing apparatus 60 realizes the detection data receiving means 61 and the device identification data input means 62 by the above-described hardware alone or in cooperation.

  The information processing device 50 and the investigation information processing device 60 may realize the request packet transmission unit 54 and the response packet reception unit 55 of FIG.

  Each of the above means is realized by a program for realizing this being read into the main memory and executed by the control unit. The information processing device 50 and the investigation information processing device 60 may be dedicated information devices including the above-described means, or may be information devices having other functions such as a personal computer, a television, a router, and a gateway.

  The identification server 300 includes a CPU (Central Processing Unit), a RAM (Random Access Memory), a ROM (Read Only Memory) and the like as a control unit, a wired / wireless compatible communication device as a communication unit, and a storage unit as a storage unit. Either or both of a hard disk and an SSD (Solid State Drive) are provided. That is, the basic functional configuration of the hardware may be a Web server.

  The electric appliance 10 and the investigation electric appliance 12 include a CPU (Central Processing Unit), a RAM (Random Access Memory), a ROM (Read Only Memory), and the like as control units, and a wired / wireless compatible communication device as a communication unit. And a hard disk, an SSD (Solid State Drive), or both as a storage unit. You may provide display parts, such as a monitor which displays an image. The electrical appliance 10 is assumed to include a computer, but may be an electrical appliance belonging to a household electrical appliance or a commercial electrical appliance as long as the electrical appliance 10 includes the above-described configuration.

  FIG. 6 is a flowchart of second identification processing executed by the information processing device 50, the identification server 300, and the investigation information processing device 60.

  The information processing apparatus 50 determines whether or not the new electrical appliance 10 is connected to the network for investigation 100 (step S20). As a method for detecting whether or not a new electrical appliance 10 is connected to the network under investigation 100, for example, a determination is made based on whether or not the information processing apparatus 50 has received a broadcast packet transmitted by the electrical appliance 10 for the first time. You can do it. If the information processing apparatus 50 determines that the new electrical appliance 10 is connected to the network under investigation 100 (step S20: “YES”), the process proceeds to step S21. If the information processing apparatus 50 does not determine that the new electrical appliance 10 is connected to the network (step S20: “NO”), the process returns.

  The detection data receiving unit 301 (for example, configured by the request packet transmitting unit 54 and the response packet receiving unit 55) of the information processing apparatus 50 transmits and receives a packet to the newly connected electrical appliance 10, A series of detection data (consisting of a request packet and a response packet) is received from the electrical appliance 10. The detection data transmission means 53 of the information processing apparatus 50 transmits this series of detection data to the identification server 300 (step S21).

In the same way as described above, the device identification method compares the dictionary data stored in advance with the detection data, and determines the type of the corresponding electrical appliance 10.

  Here, when the device identification unit 302 can identify the device of the electrical appliance 10 (step S23: “YES”), the identification server 300 uses the identified type of the electrical appliance 10 as device data as the information processing apparatus. 50. The information processing apparatus 50 receives this and completes identification of the device.

  On the other hand, when the device identification unit 302 cannot identify the device of the electrical appliance 10 (step S23: “NO”), the unidentification determination unit 304 of the identification server 300 determines that the device identification has not been completed. The investigation-required determination means 305 determines the detection data of the unidentified electrical appliance 10 as the investigation-required data. Then, the investigation command unit 306 transmits a request packet configured as a part of the investigation required data to the investigation information processing device 60 and receives the response packet. The series of detection data is instructed to be transmitted to the identification server 300 (step S24).

  Upon receiving this command, the detection data receiving means 61 of the investigation information processing device 60 receives detection data from the identification server 300 and transmits a request packet to a plurality of connected investigation electrical appliances 12. In response to this, a response packet is received from each investigation electrical appliance 12 and stored as a series of detection data. The plurality of detection data is transmitted to the identification server 300. Since these detection data are detection data of the investigation electrical appliance 12, the type of the electrical appliance is determined by an administrator input from the device identification data input means 62, and the detection data and the electrical appliance Types (model name, manufacturer name) are associated in advance.

  The comparison unit 308 of the identification server 300 receives the plurality of detection data, and individually compares the received detection data with the investigation required data (step S25). That is, the response packet of the detected data is compared with the response packet of the investigation required data.

  Here, the unidentified device identification unit 309 of the identification server 300, when there is detection data whose detection data and investigation required data are the same, almost the same, or similar, has the investigation electrification associated with the detection data. The manufacturer name and model name of the product 12 are determined as the type of the electrical appliance 10. That is, device identification is completed (step S26). When the device identification is completed, the manufacturer name and model name of the corresponding electrical appliance 12 are transmitted as device data to the information processing apparatus 50 (step S27). The device data receiving means 59 of the information processing apparatus 50 receives this device data (step S28) and completes device identification.

  Note that the unidentified device identifying unit 309 of the identification server 300 determines that the identification server 300 does not detect the detection data having the same, substantially the same, or similar detection data and the investigation required data. In addition, it may be processed so that the survey-required data is transmitted and the survey-required data is added to the electrical appliance list requiring investigation. In addition, the investigation information processing apparatus 60 may be configured to output a message that prompts the administrator to pay attention so that the electrical appliance 10 is investigated again.

[Model identification of electrical appliances]
Next, based on FIGS. 7 to 15, the information processing device 50 and the investigation information processing device 60 (hereinafter, the information processing device 50 will be described as a representative) determines the type (model, etc.) of the electrical appliance 10. A method of automatically identifying will be described. FIG. 7 is a diagram showing the overall configuration of the network under investigation 100 including the information processing apparatus 50. FIG. 8 is a functional block diagram of the information processing apparatus 50 and the appliance 10.

  The information processing apparatus 50 includes a request packet transmission unit 54, a response packet reception unit 55, a definition file storage unit 56, a scoring unit 57, and an electrical appliance type determination unit 58. Each of the above means is realized by a program for realizing this being read into the main memory and executed by the control unit. Note that the definition file storage means 56, scoring means 57, and electrical appliance type determining means 58 are functions independent of the electrical appliance 10, so that a public network such as the identification server 300 can be used as a SaaS type identification method. 3 may be provided on the server side.

  The request packet transmission unit 54 has a function of transmitting a request packet to be described later, and is realized by a communication I / F and a control unit.

  The response packet receiving unit 55 has a function of receiving a response packet described later, and is realized by a communication I / F and a control unit.

  The definition file storage unit 56 has a function of storing a definition file described later, and is realized by a hard disk, a main memory, or the like.

  The scoring unit 57 has a function of scoring each definition file based on the definition file, and is realized by a control unit, a hard disk, a main memory, and the like.

  The appliance type determining means 58 has a function of finally determining the type of appliance, and is realized by a control unit, a hard disk, a main memory, and the like.

  The electrical appliance 10 includes at least a control unit realized by a CPU, a communication unit 24 realized by a communication I / F, and a storage unit 22 realized by a hard disk and a main memory, and is an input device such as a mouse. A certain operation unit 23 may be provided.

[Type flow chart]
FIG. 9 is a flowchart of the type determination process. First, the request packet transmission unit 54 of the information processing apparatus 50 transmits a request packet to the electrical appliance 10 (step S30).

  The request packet is packet data that the information processing apparatus 50 transmits to the electrical appliance 10 in order to receive a response packet for determining the type of the electrical appliance 10.

  The request packet may be, for example, a command such as ARP (Address Resolution Protocol), ICMP (Internet Control Message Protocol), or SNMP (Simple Network Management Protocol), and uPnP (Universal PlyDlN) ) May be a compliant protocol.

  Note that the request packet transmission unit 54 may be a mode in which a request packet is periodically transmitted to the electrical appliance 10. That is, the request packet transmitting unit 54 transmits the request packet every several tens of seconds, every few minutes, or every several hours, thereby detecting the appliances 10 that are communicably connected at a predetermined timing.

  That is, when a new electrical appliance 10 is connected to the network under investigation 100, in order to detect the electrical appliance 10, the information processing apparatus 50 periodically transmits a request packet at a predetermined timing. . According to this, since the information processing apparatus 50 can obtain information on the electrical appliance 10 when the customer connects a new electrical appliance 10, the management of the electrical appliance 10 in the network under investigation 100 is possible. Becomes easy.

  The electrical appliance information is information relating to the type of electrical appliance, and is information including at least the type of electrical appliance (manufacturer name, device name, etc. for identifying the type of electrical appliance).

  Next, the response packet receiving unit 55 of the information processing apparatus 50 receives a response packet from the predetermined electrical appliance 10 (step S31).

  The response packet is a packet transmitted from the electrical appliance 10, and is packet data for determining the type of the electrical appliance 10 or as a clue for determining the type of the electrical appliance 10. The response packet is, in principle, a response packet transmitted from the electrical appliance 10 that has received the request packet transmitted from the information processing apparatus 50. However, in an exceptional case, the response packet is a response packet of the request packet. Instead, it may be a broadcast packet from the electrical appliance 10.

  Next, the information processing apparatus 50 performs a definition file reference process (step S32). The control unit of the information processing apparatus 50 refers to and compares the definition file stored in the definition file storage unit 56 and performs the next scoring process (step S33).

  The definition file (dictionary data) is data for which the detection data and the type of the electrical appliance 10 are predetermined for each electrical appliance 10 and is necessary for specifying the type of the electrical appliance 10. Referring to FIG. 15 to be described later, the definition file (electrical appliance A definition file) is composed of one or more definition items (X5, Y2, Z3). Each definition item is scored and compared. 10 (in this case, electrical appliance A) is specified. The definition item is definition data for specifying the type of the electrical appliance 10 with one request packet and response packet.

  Next, the scoring means 57 of the information processing device 50 compares the definition file with the response packet and scores (scoring) (step S33).

  The scoring will be described with reference to FIG. The information processing apparatus 50 transmits one or more request packets (A1, B1, C1), and receives response packets (X5, Y8, Z9) corresponding thereto. Then, the information processing apparatus 50 refers to the definition items of the definition files for each electrical appliance (the electrical appliance A definition file, the electrical appliance B definition file, and the electrical appliance C definition file) stored in the definition file storage unit 56. Compare with response packet.

  For example, the case where an ARP command is transmitted as a request packet and this response is received from an electrical appliance 10 will be described. By transmitting the ARP command to the target electrical appliance 10, a packet including information on the MAC address of the target electrical appliance 10 is received as a response packet.

  As shown in FIG. 10, the MAC address consists of a 48-bit code, the upper 24 bits are assigned as a vendor ID, a vendor-specific ID is given, and the next 8 bits is a model ID.

  The definition file storage means 56 may store a table for configuring a definition file for each electrical appliance. For example, as shown in FIG. 11, as a MAC address manufacturer table, the code of the upper 24 bits and the manufacturer name of the electrical appliance 10 (not necessarily the vendor name of the manufacturer, but the entire electrical appliance 10 having the communication I / F). Vendor (manufacturer) name), points for scoring, and ID are associated with each other. Furthermore, as shown in FIG. 12, as the MAC address model table, the upper 8 bit code, the model name of the electrical appliance 10, the points for scoring, and the ID are associated with each other.

  By extracting each element of this MAC address maker table and MAC address model table, it becomes a definition item and constitutes a definition file for each electrical appliance. For example, ID001 in the MAC address maker table corresponds to X5 (see FIG. 15) (definition item X5) of the appliance A definition file, and ID010 in the MAC address device table corresponds to Y2 (definition item Y2 in the appliance A definition file). )

  Upon receiving the A1 packet transmitted as the request packet, the electrical appliance 10 transmits a response packet. The response packet (X5) is compared with the definition items in the definition file of the electrical appliance A. If they are the same, points are given with reference to each table.

  For example, in the above example, the case where the response packet X5 is a packet including information on the target MAC address and the 48-bit code is “04-A3-43-5F-43-23” will be described. Since the upper 24 bits are the same as the definition item X5 (ID001), 0.3 points are given. Further, in the next 8 bits, since it is the same as the definition item (ID010), 0.3 points are given. Therefore, the electric appliance A definition file can obtain a total of 0.6 points.

  In the above example, one request packet (A1) is scored for two definition items (ID001, ID010) by a response packet (X5). A plurality of definition items may be scored from the packet.

  Next, the information processing apparatus 50 compares the response packet Y8 with Y2 of the appliance A definition file and compares the response packet Z9 with Z3 of the appliance A definition file to obtain each point (FIG. 15). The total score of the electrical appliance A definition file is the sum of all the points thus obtained. For this, an overall score is obtained for the definition file for each electrical appliance, such as the electrical appliance A definition file, the electrical appliance B definition file, the electrical appliance C definition file,.

  In the above description, the case where the response packet X5 and the definition item X5 are the same has been described.

  As an example of judging by similarity, a mode in which 0.2 points are given if the upper 16 bits of the upper 24 bits of the response packet X5 are the same, and 0.1 points are given if the upper 8 bits are the same (packet) It may be determined by the degree of similarity of the character string. In this way, the point value can be adjusted such that the point is increased when the similarity between the response packet and the definition item is high.

  The information processing apparatus 50 receives a plurality of response packets from the electrical appliance 10 by transmitting a plurality of types of request packets.

  Next, the appliance type determining means 58 of the information processing apparatus 50 determines the type of the appliance 10 (device) (step S34). That is, scoring as described above is performed on the definition files of all electrical appliances, the obtained scores are compared, and a definition file with a high score is extracted to determine the type of the electrical appliance 10.

  For example, as described above, the overall score is obtained for the definition file for each electrical appliance, such as the electrical appliance A definition file, the electrical appliance B definition file, the electrical appliance C definition file, and the highest score. A definition file for a high electrical appliance is extracted to identify the electrical appliance 10.

  Referring to FIG. 15, for example, since the response packet (X5, Y8, Z9) and X5 of the appliance A definition file (X5, Y2, Z3) are the same, the appliance A definition file has 0.6. Suppose you get points. On the other hand, each definition item (X1, Y7, Z1) of the appliance B definition file is not the same as the response packet (X5, Y8, Z9). Suppose you have 3 points.

  In the appliance C definition file (X5, Y8, Z8), the response packet (X5, Y8, Z9) and the definition items X5 and Y8 are the same. Suppose that it was acquired. In this case, among the definition files for electrical appliances A to C, the definition file for electrical appliance C is determined to be the highest overall point (0.9 points), and the definition file C is extracted. Is determined to be appliance C.

  As an example, the electrical appliance A definition file is defined as a definition file up to the manufacturer name A company, and the electrical appliance B definition file is one of the types of equipment in addition to the manufacturer name company A (AB-01). The definition file can be specified up to. In this case, when an electrical appliance 10 is manufactured by Company A and is of the type AB-01, the electrical appliance B definition file has a higher point than the electrical appliance A definition file. Therefore, the electrical appliance 10 is determined to be the electrical appliance B (AB-01 of company A) that has a high overall score.

  Conversely, when a certain electrical appliance 10 is manufactured by Company A and is of the type BC-03, it can be specified by the definition file of Electrical Appliance A or Electrical Appliance B up to that manufactured by Company A. Therefore, although the device name cannot be specified, at least the manufacturer name can be specified, and the appliance information can be specified step by step.

  As an example of a determination element for scoring other than the MAC address, an example in which determination is performed based on a TCP / IP port will be described with reference to FIGS. The type of the electrical appliance 10 is specified according to the usage status of the port number specially used (bound) in the electrical appliance 10.

  As shown in FIG. 13, in the electrical appliance X, port numbers 5000 and 5002 are in use, and 5001 is not in use. For example, this status is detected by a NETSTAT command. Then, as shown in FIG. 14, the port number table stored in the definition file storage means 56 is referred to, the port numbers being used (bound) are compared, and the identity with the definition item of ID100 is determined. And give points. Port numbers 5000 and 5002 are in use, and if number 5001 is not used, 0.2 points are given.

  When the NETSTAT command is used, the NETSTAT command may transmit a packet to the partner electrical appliance 10 as a request packet. However, the information processing apparatus 50 receives a broadcast or multicast packet from the electrical appliance 10 in advance. The NETSTAT command result may be obtained by using these received packets.

  That is, even if the information processing apparatus 50 does not transmit a NETSTAT command serving as a request packet to the electrical appliance 10, a broadcast or multicast packet (port number) transmitted from the electrical appliance 10 that has been received so far. The scoring process may be performed on the basis of a packet for notifying the binding state of the above.

  Note that points are assigned not only when the port numbers in the port number table and the binding status are completely the same, but also what percentage of existing ports are in use and what percentage is not in use. The points may be given according to the degree of use (the degree of use is not completely the same but is similar). For example, it is assumed that the usage degree of a port and points are stored in advance as a table. In this case, port numbers 5000 and 5002 are in use, and when port 5001 is not in use, 66% of the ports are in use. Therefore, when 66% of the ports are in use, the processing is such that a predetermined point is given with reference to the table.

  Further, the OS (Operating System) version may be determined and the point may be assigned. For example, an nbns (Net BIOS Name Server) packet is received as a response packet transmitted in broadcast, OS version information is acquired, the OS is identified based on this, and the OS version is identified. Points may also be awarded.

  For example, in the definition file of the electrical appliance AB-01, it is assumed that “if the OS version is“ X type ”is used, 0.5 is added as a point” is registered as a definition item. At this time, if the OS version is specified as “X type” by the nbns packet, 0.5 is added to the point of the electrical appliance AB-01.

  The means and functions described above are realized by a computer (including a CPU, an information processing device, and various terminals) reading and executing a predetermined application program. The application program is provided in a form recorded on a computer-readable recording medium such as a flexible disk, CD (CD-ROM, etc.), DVD (DVD-ROM, DVD-RAM, etc.), for example. In this case, the computer reads the application program from the recording medium, transfers it to the internal storage device or the external storage device, stores it, and executes it. The program may be recorded in advance in a storage device (recording medium) such as a magnetic disk, an optical disk, or a magneto-optical disk, and provided from the storage device to a computer via a communication line.
