In this embodiment, as an example of an information processing apparatus, a copy function, a facsimile (FAX) function, a print function, a scanner function, and input image data (image data read by a scanner function or image data formed by a print function) The present invention is applied to a so-called MFP (Multi Function Peripheral) having a function of distributing image data received by the FAX function.

  First, a configuration example of an information processing system including a multifunction peripheral and a mobile terminal device to which the present invention is applied will be described. FIG. 2 is a block diagram illustrating a configuration of the information processing system according to the first embodiment. The information processing system 10 according to the present embodiment includes a multifunction device 200 and a portable information terminal device 220. The multifunction device 200 and the portable terminal device 220 can communicate with each other by two communication means. The multifunction device 200 is connected to a network 230 and is connected to another multifunction device 240, a facsimile machine, a client terminal device, and the like via the network 230.

  The MFP 200 includes an NFC communication unit 201, a Bluetooth communication unit 202, an output application 203, a scanner unit 204, a display control unit 205, a printer unit 206, a facsimile transmission / reception unit 207, a data storage unit 208, a communication And a control unit 209.

  The NFC communication unit 201 performs non-contact bidirectional communication with the mobile terminal device 220 according to a wireless communication standard including a non-contact IC called NFC (Near Field Communication). A reader / writer and / or a tag function that incorporates a communication control program that reads information from the NFC communication unit 221 in a non-contact manner. The NFC communication unit 101 transmits / receives data by non-contact wireless communication at a short distance, that is, a communication distance of 0 to 10 cm, as compared with the Bluetooth communication unit 202 which is another communication means. In the NFC standard non-contact communication by the NFC communication unit 201, the data transfer rate (100 to 400 kbps) is slower than the data transfer rate (1 to 2 Mbps) of the Bluetooth (R) standard wireless communication by the Bluetooth communication unit 202. Used for communication of relatively small volume data. Note that the NFC communication unit 201 does not need to limit the communication standard to NFC, as long as wireless communication is possible in a relatively short distance, that is, in a communication range narrower than the communication range of the Bluetooth (R) standard described later. Other communication standards such as IrDA (Infrared Data Association) may be used.

  Further, when the mobile terminal device 220 is located (exists) within the communication range of the NFC communication unit 201, the NFC communication unit 201 uses the same communication protocol as the communication control program of the NFC communication unit 221 of the mobile terminal device 220. Wireless communication with the NFC communication unit 221 of the device 200 is established, and the password transmitted from the mobile terminal device 220 is received. Here, the password is information (decryption information according to the present invention) such as an encryption algorithm and an encryption key for decrypting encrypted data received from the mobile terminal device 220. The password may be unique information assigned to the mobile terminal device 220 or information for identifying a user who owns the mobile terminal device 220. When information for identifying a user is used, information such as an employee ID may be used. In this way, by receiving the password from the mobile terminal device 220 by NFC communication by the NFC communication unit that allows easy data transmission and reception, the user can simply move the mobile terminal device 220 closer to the multifunction device 200 without performing any special operation.

The password ID may be unique information assigned to the mobile terminal device 220 or information for identifying the user who owns the mobile terminal device 220 as long as the password ID is different from the password used for data encryption. .

  The Bluetooth communication unit 202 communicates with the mobile terminal device 220 in a non-contact manner according to the Bluetooth (R) standard. The Bluetooth communication unit 202 adopting the Bluetooth (R) standard wireless communication system transmits and receives data at a large capacity and at a high speed (1 to 10 Mbps) as compared with the NFC communication unit 201 of the NFC standard non-contact communication system. In addition, the Bluetooth communication unit 202 adopting the Bluetooth (R) standard wireless communication method can be used even if there is an obstacle as long as the distance between the devices is within 10 m, and the communication range of the NFC standard communication method. The communication range is longer than

  Specifically, the Bluetooth communication unit 202 includes a Bluetooth (R) I / F (interface) such as a Bluetooth (R) standard transceiver that receives encrypted data, and a communication control unit. The Bluetooth (R) I / F is responsible for receiving encrypted data from the mobile terminal device 220 at the connection destination.

As information used for establishing wireless communication, unique address information assigned to the Bluetooth (R) I / F is used.

  In the present embodiment, the Bluetooth communication unit 202 compliant with the Bluetooth (R) standard is used as wireless communication, but the present invention is not limited to this, and other standards, For example, the wireless communication can be performed by a so-called wireless LAN standard such as IEEE802.11a / IEEE802.11b / IEEE802.11n / IEEE802.11g. In this case, an IEEE802.11a / IEEE802.11b standard network board responsible for transmission / reception of encrypted data and a communication control unit (communication control program for controlling establishment of wireless communication by IEEE802.11a / IEEE802.11b and transmission / reception of encrypted data) ) To configure the wireless LAN communication unit. In addition, if the distance between devices is within 3 m in the UWB communication system, wireless communication can be performed according to the Wireless USB standard that enables communication at 480 Mbps, which is equivalent to wired USB 2.0. In this case, the Wireless USB communication unit may be configured by a UWB device as a Wireless USB standard responsible for data transmission and reception, and a communication control unit (communication control program) that controls establishment of wireless communication and transmission and reception of encrypted data.

  In addition, when the mobile terminal device 220 is within the communication range of the Bluetooth communication unit 202, the Bluetooth communication unit 202 uses the same communication protocol as the communication control program of the Bluetooth communication unit 222 of the mobile terminal device 220. Communication with the Bluetooth communication unit 222 is established, and the encrypted data and password ID transmitted from the mobile terminal device 220 are received. In this embodiment, the password ID is received together with the encrypted data. However, the present invention is not limited to this. For example, only encrypted data may be received from the mobile terminal device 220. Here, the encrypted data is image data, document data, text data, and other various types of data to be kept confidential, and is data to be processed in the printer unit 206 and the like. As described above, by receiving the encrypted data from the mobile terminal device 220 by the Bluetooth communication unit 202, even if the wireless communication between the mobile terminal device 220 and the multifunction device 200 is intercepted, the data that wants to maintain confidentiality leaks. The possibility can be reduced.

  The decryption processing unit 203a performs decryption processing on the encrypted data received by the Bluetooth communication unit 202 and extracts data. Specifically, the decryption processing unit 203a decrypts the encrypted data using the password received by the NFC communication unit 201. The decryption processing unit 203a may be provided in the output application 203 in advance, or may be added to the output application 203 in a plug-in format.

  Further, the decryption processing unit 203a determines whether or not the password received by the NFC communication unit 201 is a password that allows the decryption processing of the encrypted data. Specifically, when the password ID is received together with the password and the encrypted data, the decryption processing unit 203a matches the password ID received by the NFC communication unit 201 with the password ID received by the Bluetooth communication unit 202. Determine whether or not. When the password ID received by the NFC communication unit 201 matches the password ID received by the Bluetooth communication unit 202, the decryption process of the encrypted data is executed. Note that after the data extracted from the encrypted data is output, the output application 203 discards the encrypted data and the password in order to prevent information leakage from the data storage unit 208.

  On the other hand, if the password ID received by the NFC communication unit 201 and the password ID received by the Bluetooth communication unit 202 do not match, the output application 203 discards the password and encrypted data stored in the data storage unit 208. .

  If the password ID received by the NFC communication unit 201 does not match the password ID received by the Bluetooth communication unit 202, the output application 203 immediately discards the password and encrypted data stored in the data storage unit 208. However, the present invention is not limited to this. For example, when the NFC communication unit 201 receives the password and the password ID again from the mobile terminal device 220, the output application 203 does not discard the password and the encrypted data. Then, the decryption processing unit 203a determines again whether or not the password ID received by the NFC communication unit 201 matches the password ID received by the Bluetooth communication unit 202. The output application 203 discards the password and the encrypted data stored in the data storage unit 208 after the NFC communication unit 201 receives the password a predetermined number of times or after a predetermined time has elapsed.

  The display control unit 205 receives an instruction from the output application 203 and controls input / output of the operation unit. Specifically, when the password and the encrypted data stored in the data storage unit 208 are not discarded by the output application 203, a message requesting transmission of the password is displayed on the operation unit.

  The communication control unit 209 is connected to a network such as a wireless LAN, and exchanges data and the like with other devices connected to the network according to a communication protocol. Specifically, communication is established with the communication control unit 225 of the mobile terminal device 220 and, for example, a message requesting transmission of a password is transmitted.

  The scanner unit 204 reads an original with an image sensor such as a charge coupled device (CCD). The scanner unit 204 may be provided with a mechanism for performing automatic document feeding by mounting an ADF (Auto Document Feeder).

  The printer unit 206 prints data extracted by the decoding processing performed by the decoding processing unit 203a.

  The facsimile transmission / reception unit 207 transmits the data read by the scanner unit 204 or the data extracted by the decryption processing unit 203a to another multifunction device 240, a facsimile machine, a client terminal, or the like via the network 230. Further, the facsimile transmission / reception unit 207 receives data transmitted from other multifunction peripherals 240, facsimile apparatuses, and client terminals.

  The data storage unit 208 includes the password received by the NFC communication unit 201, the encrypted data received by the Bluetooth communication unit 202, the data extracted by the decryption processing unit 203a, the image data read by the scanner unit 204, and the network 230.

The received encrypted data is decrypted to extract the data (step S404).

  When the data is extracted, the output application 203 instructs the printer unit 206 to output (print) the extracted data (step 405). When data is printed by the printer unit 206, the output application 203 discards the password and encrypted data stored in the data storage unit 208 (step S406).

  Next, the encrypted data and password transmission process of the client terminal 610 configured as described above will be described. FIG. 11 is a flowchart illustrating a procedure of transmission processing performed by the client terminal 610.

  First, the document creation application 614 creates data according to an instruction from an operation unit (not shown), and stores the data in the data storage unit 613 (step S1101). The document creation application 614 receives a password and a password ID from an operation unit (not shown) (step S1102). The input password and password ID are stored in the data storage unit 613 by the document creation application 614. When the NFC communication unit 611 transmits a password and a password ID to the mobile terminal device 600, the password and password ID are stored in a tag of the NFC communication unit 611.

  First, the document operation application 602 stores the encrypted data and password ID received from the client terminal 610 in the data storage unit 223 (step S1201). Next, the Bluetooth communication unit 222 transmits the encrypted data and the password ID temporarily stored in the data storage unit 223 to the multi-function device 200 (step S1202).

  Next, the document operation application 602 stores the password and password ID received from the client terminal 610 in the data storage unit 223 (step 1203). When the user moves and the portable terminal device 600 is located within the communication range of the NFC communication unit 201 of the multifunction device 200, the NFC communication unit 601 uses the password and password ID stored in the data storage unit 223.

The received encrypted data is stored in the data storage unit 208 by the output application 203. When receiving the encrypted data and the password ID from the portable terminal device 600, the display control unit 205 displays a message requesting the transmission of the password to the operation unit in response to a command from the output application 203, and from the portable terminal device 600. The system waits for reception of the password and the password ID (step S1302).

  Next, the NFC communication unit 201 establishes communication with the NFC communication unit 601 of the mobile terminal device 600 and is transmitted from the mobile terminal device 600 when the mobile terminal device 600 is located within the communication range of the NFC communication unit 201. The received password and password ID are received (step S1303). The received password and password ID are stored in the data storage unit 208 by the output application 203.

  Next, the decryption processing unit 203a determines whether or not the password ID received by the NFC communication unit 201 matches the password ID received by the Bluetooth communication unit 202 (step S1304). In this embodiment, it is determined whether or not the password ID received by the NFC communication unit 201 matches the password ID received by the Bluetooth communication unit 202, but the present invention is not limited to this. For example, when the password ID is not received together with the password and the encrypted data, it is determined whether or not the password ID received by the NFC communication unit 201 matches the password ID received by the Bluetooth communication unit 202. First, the encryption data decryption process using the password is executed.

  If the password ID received by the NFC communication unit 201 and the password ID received by the Bluetooth communication unit 202 do not match (step S1304: No), the output application 203 causes the NFC communication unit 201 to use the password and password ID. Is determined whether or not a predetermined number of times has been received (step S1308). When the NFC communication unit 201 receives the password and the password ID for a predetermined number of times (step S1308: Yes), the output application 203 discards the password and encrypted data stored in the data storage unit 208 (step S1307).

  On the other hand, when the password ID received by the NFC communication unit 201 matches the password ID received by the Bluetooth communication unit 202, the decryption processing unit 203a uses the password received by the NFC communication unit 201 to perform the Bluetooth communication unit 202. The received encrypted data is decrypted to extract the data (step S1305).

  When the data is extracted, the output application 203 instructs the printer unit 206 to output (print) the extracted data (step 1306). When the data is printed by the printer unit 206, the output application 203 discards the password and the encrypted data stored in the data storage unit 208 (step S1307).
