Description

  The present invention relates to a transmission apparatus, a transmission method, and a transmission program for transmitting recorded contents of a sheet with an RFID (Radio Frequency Identification) tag.

In recent years, with the spread of personal computers (PCs), there has been a demand for integrated handling of visual information obtained by recording characters and figures on paper and digital information that can be handled by a PC. Paper has been proposed. Specifically, the digital information read together with the visual information from the RFID tag printing paper is transmitted to the transmission destination at the transmission source, and the received visual information and digital information are output to the RFID tag printing paper on the receiving side at the transmission destination. A facsimile apparatus that restores a transmission source document is known (for example, see Patent Document 1).
JP 2002-337426 A

  However, according to the conventional facsimile apparatus, if the counterpart apparatus is an apparatus that does not have a function of outputting to the RFID-tagged printing paper, the visual information can be output, but the digital information cannot be output. As a countermeasure for this case, a method in which the sender outputs the content of the RFID tag on paper and transmits it by fax can be considered. However, even if confidential information with high importance or confidentiality that is not desired to be seen by a third party is stored in the RFID tag, it is output on paper at the time of reception, so it is easily seen by a third party. There is a possibility.

  Therefore, an object of the present invention is to provide a transmission apparatus, a transmission method, and a transmission program that can transmit with high confidentiality even when the counterpart apparatus does not support the transmission sheet with the RFID tag.

In order to achieve the above object, according to a first aspect of the present invention, there is provided a transmitting device that transmits information to a compatible device that supports a transmission sheet with an RFID tag and a non-compatible device that does not support the transmission sheet with an RFID tag. A first reading unit that reads first transmission information recorded on the transmission sheet; a second reading unit that reads second transmission information recorded on the RFID tag;
When the counterpart device is the non-compatible device, the first transmission information is transmitted in the predetermined transmission mode, and the second transmission information is transmitted in a transmission mode having higher secrecy than the predetermined transmission mode. Provided is a transmission apparatus comprising transmission control means.

  The transmission control means may be configured to transmit in a highly confidential transmission mode as the highly confidential transmission mode.

  The transmission control means transmits, as the highly confidential transmission mode, the first transmission information by fax, and the second transmission information is output from the counterpart device by inputting a password. May be transmitted in a confidential polling mode in which information is transmitted by fax, or in a mode in which the storage location information of the second transmission information is notified by e-mail. By transmitting the second transmission information by a transmission method different from normal fax transmission, the secrecy of the second transmission information can be maintained.

  As the highly confidential transmission mode, the transmission control means transmits the first transmission information as it is, and the second transmission information is transmitted by changing at least the content of a confidential page or page portion. Can be configured. The confidentiality of the second transmission information can be kept by changing and transmitting the confidential portion.

  The transmission control means may transmit the content after reducing the content. When a confidential page or page portion is reduced, it is not completely recognized, so that confidentiality can be maintained.

  The transmission control means may transmit the content hidden at random. If a confidential page or a portion of a page is hidden at random, it is not completely recognized, so that confidentiality can be maintained.

  The transmission control means may transmit the storage location information of the contents. In this case, when the confidential part is reduced or hidden at random, the original storage location information of the part may be transmitted together. Since the original cannot be obtained unless the storage location information is accessed, confidentiality can be maintained.

  As the highly confidential transmission mode, the transmission control means may transmit the first transmission information as it is, and the second transmission information other than confidential pages. By not transmitting a confidential page, confidentiality can be maintained completely.

  The transmission control unit may transmit the first transmission information and the content by fax, Internet fax, or electronic mail.

  In order to achieve the above object, a second aspect of the present invention is a transmission device that transmits information to a compatible device that supports an RFID tag transmission sheet and a non-compatible device that does not support the RFID tag transmission sheet. A first reading step for reading the first transmission information recorded on the transmission sheet; a second reading step for reading the second transmission information recorded on the RFID tag; In this case, the method includes a step of transmitting the first transmission information in the predetermined transmission mode and transmitting the second transmission information in a transmission mode having higher secrecy than the predetermined transmission mode. A featured transmission method is provided.

  In order to achieve the above object, a third aspect of the present invention provides a transmission program for causing a computer to execute the above transmission method.

  According to the first to third aspects, the recorded content of the transmission sheet is transmitted in a transmission mode that can be recognized at the time of reception, and the recorded content of the RFID tag is transmitted in a highly confidential transmission mode that cannot be recognized at the time of reception. By doing so, it is possible to improve the confidentiality of confidential information included in the recorded content of the RFID tag even when the counterpart device does not support the sheet with the RFID tag.

  As the transmission sheet, a sheet made of paper or plastic can be used. The first transmission information recorded on the transmission sheet can be optically read using a photoelectric conversion element, and the second transmission information recorded on the RFID tag can be read using radio waves. The transmission mode with high secrecy and the content of transmission can be considered. Highly confidential transmission modes include confidential transmission, confidential polling, e-mail notification of storage location information, and the like. The highly confidential transmission contents include image reduction, character blinds, page selection, and the like. The storage location information refers to location information accessible by a user terminal such as a personal computer (PC) such as a URL and a file name.

  According to the present invention, highly confidential transmission is possible even when the counterpart device does not support a transmission sheet with an RFID tag.

(Operation of communication system)
Next, the operation of the communication system 1 having the above configuration will be described for each case.

(1) Write operation to the RFID tag paper 9 When writing data to the RFID tag paper 9, the user creates information to be written or printed on the RFID tag paper 9 by the user terminal device 2 or the like. The data is stored in the HDD 45 of the multifunction machine 3. Next, the user sets the RFID-tagged paper 9 on which no information is written in the tagged paper tray 33.

  Next, the user operates the operation display unit 50 to instruct writing to the RFID-tagged paper 9. In response to this instruction, the CPU 41 drives the paper feed roller 34 and the transport roller 35 to transport the RFID tagged paper 9 on the tagged paper tray 33 to the printing unit 20. When the RFID tag 91 of the paper 9 with the RFID tag reaches the RFID writer 16, the write information read from the HDD 45 is written to the RFID tag 91 by the RFID writer 16 wirelessly in a data storage format such as PDF (Portable Document Format). It is.

  When the writing of the image data 901 and the text data 902 to the RFID tag 91 is completed, the RFID-tagged paper 9 is sent to the printing unit 20, and the notation information 93 is printed on the surface of the RFID-tagged paper 9 by the printing unit 20. The RFID-tagged paper 9 for which the printing of the notation information 93 has been completed is discharged to the paper discharge tray 12. By these operations, a manuscript (paper 9) in which information is stored in the RFID tag 91 is created.

(2) Transmission operation of the multifunction device 3 to a non-compatible device As described above, the notation information 93 is printed on the surface of the paper 92 and the RFID tag paper 9 with the data 901 and 902 written on the RFID tag 91 is used as a document. The operation of transmitting the contents of this document to the non-compatible device of the multifunction device 3 will be described. By reading the data 901 and 902 of the RFID tag 91 and the scanner 13, the notation information 93 of the paper 92 is accumulated in the HDD 45 of the multifunction machine 3 to become accumulated data, and the following transmission processing is performed on the accumulated data. Here, information transmission between the multifunction machine 3 and the user terminal device 6 or the FAX machine 8 can be performed by the following three methods.

(A) Fax is transmitted from the multifunction machine 3 to the FAX machine 8 in the “confidential” mode, and is taken out as “confidential document” on the FAX machine 8 side.
(B) The confidential polling with a password is set for the stored data of the multifunction device 3, and the stored data is extracted by the confidential polling by inputting the password from the multifunction device 3 by the FAX machine 8.
(C) The multi-function device 3 notifies the user terminal device 6 of a URL (Uniform Resource Locator) indicating the storage location of the stored data by e-mail (URL notification), and the recipient accesses the notified URL to access the RFID tag 91. Browse the recorded contents of. In this case, it may be configured such that the recipient can only browse and not permit printout on the paper, or that the recipient is permitted to print on the paper when a predetermined password is input. May be.

  4A and 4B show the above processes (a) to (c).

  First, as shown in FIG. 4A, the user sets the RFID-tagged paper 9 on the transmission tray 11 with the writing surface down (S101). Next, the user selects “Transmission of RFID-tagged paper to a non-compatible device” using the touch panel of the operation display unit (UI) 50 (S102). The transmission method of confidential polling / URL notification is selected (S103).

  When the user selects confidential transmission (S104), the operation display unit 50 inputs the destination telephone number, the number of stored data, and the password (S105), and when confidential polling is selected (S106), the storage is performed. The data number and password are input (S107), and when the URL notification is selected (S108), the mail address of the user terminal device (PC) 6 that is the destination is input (S109). If the cancel button is pressed by the user (S110: YES), the cancel process is executed (S130), and the process ends.

  Next, when any one of the above steps S105, S107, and S109 is completed, the CPU 41 selects a size for transmitting the notation information 93 of the paper 92 read by the scanner 13 (S111), and the data 901 of the RFID tag 91 is selected. , 902 are selected (S112). The default transmission size of the paper 92 is the original paper size, and the default transmission size of the data in the RFID tag 91 is the same as the paper size when the paper 92 is read.

  Next, as shown in FIG. 4B, the CPU 41 determines whether or not the user has pressed the cancel button (S113). If the cancel button is pressed (S113: YES), the CPU 41 executes a cancel process (S114). ). When the cancel button is not pressed (S113: NO), the CPU 41 determines whether or not the start button is pressed (S115). When the user presses the start button (S115: YES), the CPU 41 reads the data of the RFID tag 91 with the RFID reader / writer 14 (S116), and further operates the scanner 13 to read the notation information 93 of the RFID tag paper 9. (S117). Next, the CPU 41 determines whether or not the cancel button is pressed (S118). When the cancel button is pressed (S118: YES), a cancel process is executed (S119).

  If it is determined in step S118 that the cancel button has not been pressed (S118: NO), the CPU 41 determines whether the transmission method is confidential transmission (S120), confidential polling (S121), or URL notification (S122). Processing of confidential transmission (S123), confidential polling (S124), or URL mail transmission (S125) is executed to the partner apparatus. Next, the CPU 41 determines whether or not the cancel button is pressed (S126). If it is determined that the cancel button is not pressed (S126: NO), the CPU 41 determines whether or not a series of processing is completed (execution completion) (S127). ). If the execution is complete (S127: YES), the completion of the process is displayed on the operation display unit 50 (S128) to notify the user.

In the above-described step S102, the configuration is described in which the user selects “transmission of RFID-tagged paper to a non-compatible device” using the touch panel of the operation display unit (UI) 50. However, the transmission destination stored in advance is described. “Transmission of RFID-tagged paper to non-compatible device” may be selected based on the information on whether or not the RFID-tagged paper is supported for each device, or communication with a specified destination device is performed and the destination device is selected. May be selected to select “Send RFID-tagged paper to non-compatible device”.

(3) Transmission operation to the compatible machine of the multifunction machine 3 When the counterpart apparatus is a compatible machine of the paper 9 with the RFID tag, information read from the RFID tag 91 and the paper 92 is transmitted as a fax image, and the corresponding machine Then, of the received data, write data to the RFID tag 91 is written to the RFID tag, write data to the paper 92 is written to the paper, and the paper 9 with the RFID tag is restored.

(Effects of the first embodiment)
According to the first embodiment, the following effects are obtained.
(A) If the counterpart device does not support the RFID-tagged paper 9, data 901 can be selected because one of the transmission methods of confidential transmission, confidential polling, or URL notification can be selected according to the communication method of the counterpart device. , 902 can be prevented from leaking to a third party from an image at the time of transmission.
(B) Since the data on the RFID 91 is browsed and taken out on the receiving side, the sending side can save the trouble of taking out the data portion of the RFID 91 and transmitting it separately.

[Second Embodiment]
6A and 6B show processing of the communication system according to the second exemplary embodiment of the present invention. FIG. 5 shows a transmission method to the FAX machine in the present embodiment.

  In this embodiment, when data 901 and 902 having confidential information of the paper 9 with an RFID tag is transmitted to a partner device such as the user terminal device 6, the FAX machine 8, the multifunction device 60, the notation information of the paper 9 with an RFID tag 93 and the URL are transmitted to the partner apparatus, and other processing and hardware configuration are the same as those in the first embodiment.

  The user terminal device 6 can send and receive mail, and the multi-function device 60 can receive iFAX. If the FAX machine 8 does not have an Internet connection function, the URL is accessed separately using a PC or the like. This will be described in detail below with reference to FIGS. 6A and 6B.

  In the present embodiment, the processes in steps S101 and S102 are the same as those in the first embodiment, and thus the description is omitted unless particularly necessary. When the transmission of the RFID tag paper 9 to the non-compliant device is selected in S102, the operation display unit 50 selects “Send paper portion and URL of RFID tag data” (S201), and further, FAX, iFAX, Which of the mails is used for transmission is selected (S202).

  Depending on the transmission method selected in step S202, the user receives a FAX when selecting FAX (S203), the telephone number of the FAX machine 8 (S204), or when selecting iFAX (S205). In the case of selecting the previous mail address (S206) or mail (S207), the mail address (S208) of the user terminal device 6 is input. When this input is completed, the processing of steps S111 to S116 is performed by the CPU 41 as in the first embodiment, and the data of the RFID tag 91 is further stored in the MFP 3 as shown in FIGS. 6B and 5. The process of storing in the HDD 45 is performed (S209). Next, similarly to the first embodiment, the processing of steps S117 and S118 is performed by the CPU 41.

  Thereafter, the CPU 41 performs transmission according to the selection of FAX, iFAX, or mail (“YES” in S210, S212, and S214) (S211, S213, and S215). When the selected transmission is completed, the processing in steps S126 to S129 is executed as in the first embodiment.

  For example, a case where FAX transmission is selected in step S202 will be described with reference to FIG. When FAX transmission is selected in step S202, as shown in FIG. 5, the data of the RFID tag 91 is accumulated in the HDD 45 in the multifunction machine 3 (S209), and in step S211, the paper 92 read in step S117 is read. The notation information 93 and the URL information for browsing are generated as FAX image data, transmitted to the FAX machine 8, and printed out as a received image 81 by the FAX machine 8. In the received image 81, a URL for browsing and an explanatory text “Please access http: // www....” Are printed as a message 82. The recipient sees the URL, accesses from a PC or the like, and executes browsing and downloading of the data 901 and 902 stored in the multifunction machine 3. Such processing is similarly performed in the multi-function device 60. Transmission in this case is iFAX.

  According to the second embodiment described above, when the counterpart device does not support the RFID-tagged paper 9, confidential information is transmitted by attaching URL information to the counterpart device by FAX, iFAX, or mail. Since the recipient can obtain the URL by accessing the URL, it is possible to prevent the confidential information from leaking to the third party from the image at the time of transmission.

[Third Embodiment]
FIG. 8 shows processing of a communication system according to the third embodiment of the present invention. FIG. 7 shows a transmission method to a FAX machine according to the third embodiment.

  The present embodiment is intended for FAX transmission to the FAX machine 8 or the MFP 60 in the first embodiment, and the image size of the paper 92 of the paper 9 with the RFID tag is kept as it is, and stored in the RFID tag 91. 7 is transmitted to the FAX machine 8 as shown in FIG. 7 together with a transmission image 84 of notation information 93 together with a reduced transmission image 83 reduced to such an extent that an approximate image can be understood or cannot be read. Other processing and hardware configuration are the same as those in the first embodiment. When the receiver needs the data of the RFID tag 91, the receiver is requested to provide the printed document and the storage medium.

  In the present embodiment, description of the same processing as in the first embodiment will be omitted. First, the user sets the RFID-tagged paper 9 on the transmission tray 11 with the writing surface down (S101). Next, when the user selects “Transmission of RFID-tagged paper to non-compatible device” on the touch panel of the operation display unit (UI) 50 (S102), the user selects “FAX transmission: RFID tag” on the operation display unit 50. "Reduce data in" is selected as the transmission method (S301), and the telephone number of the FAX machine 8 as the transmission destination is input (S302).

  Next, after executing the processes of steps S110, S115, and S116, the CPU 41 reads the data of the RFID tag 91 from the HDD 45 and reduces it (S303). Further, the CPU 41 operates the scanner 13 and the related transport mechanism, and reads the notation information 93 on the paper 92 (S304). When the reading of the paper 92 is completed, the CPU 41 activates the fax communication unit 48 to start FAX transmission to the FAX machine 8 (S305). Next, the CPU 41 executes the processes of steps S126 to S128.

  According to the third embodiment described above, the reduced transmission image 83 obtained by reducing the data stored in the RFID tag 91 is transmitted to the FAX machine 8 together with the transmission image 84 of the notation information 93 of the paper 92 of the paper 9 with the RFID tag. By doing so, the receiver can grasp the outline of the confidential information, so that the paperwork can be efficiently advanced.

[Fourth Embodiment]
FIG. 12 shows processing of the communication system according to the fourth embodiment of the present invention. FIG. 9 shows a transmission method to a FAX machine in the fourth embodiment.

  In this embodiment, as shown in FIG. 9, the data on the RFID tag 91 is randomly blacked (scrambled) without changing the image of the paper 92 of the paper 9 with the RFID tag as shown in FIG. The scrambled image 85 processed so that only the contents of the part can be understood is transmitted to the FAX machine 8 and the multi-function device 60 together with the transmission image 84 of the paper 92. Other processing and hardware configuration are the first. This is the same as the embodiment. When the receiver needs the data stored in the RFID tag 91, the receiver requests the sender to mail the printed document.

  In the present embodiment, description of the same processing as in the first embodiment will be omitted. First, the user sets the RFID-tagged paper 9 on the transmission tray 11 with the writing surface down (S101). Next, when the user selects “Send RFID tag paper to non-compatible device” on the operation display unit (UI) 50 touch panel (S102), send “FAX transmission: scramble data in RFID tag”. The method is selected (S401). Next, the telephone number of the FAX machine 8 or the multi-function machine 60 that is the transmission destination is input by the user (S302).

  Next, the CPU 41 executes the processing of steps S110, S115, and S116 as in the first embodiment, and then reads the data of the RFID tag 91 stored in the HD 45 (S116), and conceals this data in scramble. (Blind of characters, etc.) is executed (S402).

  FIG. 10 shows the scrambled image generation process in step S402. In this figure, (a) shows the original image 86 before scramble processing stored in the RFID tag 91, (b) shows the contents of the scramble data 87, and (c) shows the original image 86 in (a). A scrambled image 88 in which the scrambled portion 89 is erased by the scramble data 87 is shown.

  FIG. 11 is an explanatory diagram showing generation of the scramble data 87. As the scramble data 87, for example, a number from 0 to 9 is generated for each pixel by a random number generator, and if the number is divisible by 3, the data portion is M pixels × N lines.

  In the example of FIG. 11, “6” occurs at the third pixel in the main scanning direction (first pixel in the sub-scanning direction), and (3 pixels from the third pixel in the main scanning direction) × (3 pixels in the sub-scanning direction) "9" occurs at the seventh pixel in the main scanning direction (first pixel in the sub-scanning direction), and (3 pixels in the main scanning direction from the seventh pixel) x (3 pixels in the sub-scanning direction) ... This is the case when scrambled. Note that the degree of scramble is adjusted so as not to be too invisible and not too visible. In this example, 0 to 9 are generated equally by the random number generator. However, a method of scrambled the 30th (m is an arbitrary integer) pixel can be considered. Alternatively, it may be displayed on the operation display unit 50 to allow the user to adjust the degree of scramble.

  Returning to FIG. 12, in step S <b> 304, the CPU 41 operates the scanner 13 and the transport mechanism to read the description surface of the paper 92 of the RFID tagged paper 9. Thereafter, when reading of the RFID-tagged paper 9 is completed, the CPU 41 activates the fax communication unit 48 to start FAX transmission to the FAX machine 8 as shown in FIG. Furthermore, the processes of steps S126 to S128 are executed.

  According to the fourth embodiment described above, by transmitting the scrambled data of the data of the RFID tag 91 together with the notation information 93 of the paper 9 with the RFID tag to the FAX machine 8 or the multi-function device 60, the recipient is concealed. Since the outline of information can be grasped, paperwork can be efficiently advanced.
