Description

  The present invention relates to a seal management system for managing a seal for a document.

  Conventionally, for items that require approval within an organization, such as a company, a document has been provided with a stamp field, and approval is obtained when an approver, such as a manager, stamps this document. The mechanism that is made is used. A document that needs to be approved in this way can be copied by, for example, copying, and therefore may be forged.

Here, barcode information is described in a document provided with the above-described stamping field, and a non-contact data carrier in which the seal holder ID information is written is built in the stamp so that the document is printed at the time of stamping. In addition to reading bar code information from the contact information, a technique for reading seal stamp holder ID information from a non-contact data carrier and managing them in association with each other is considered (for example, see Patent Document 1). Using this technology, it is possible to electronically manage that a document has been stamped, and even if it is copied, by checking the electronically managed data, the approver can create a document. It can be confirmed whether or not the seal has actually been made.

The information is read in a non-contact state, or the information is written in the storage unit in a non-contact state. Then, the chip ID written in the storage unit becomes the first identification information, and the document 10 can be identified.

  A printer 30 serving as a printing device that prints information 12 on the document 10 includes a printing unit 31 that prints information 12 on the document 10 and an antenna for reading the chip ID from the RF-ID chip 11 inserted in the document 10. 34, an antenna 35 for reading a chip ID unique to the IC chip as an issuer ID from an IC chip (not shown) built in the mobile phone 70 owned by the issuer of the document 10, and the RF-ID chip 11. The information reading unit 32 reads the chip ID through the antenna 34, and reads the chip ID from the IC chip (not shown) built in the mobile phone 70 as the issuer ID through the antenna 35. Information transmission for transmitting the chip ID read from the IC chip (not shown) built in the RF-ID chip 11 and the mobile phone 70 33 and is provided, the chip ID transmitted from the information transmitting unit 33 will be received by the management server 40 via the LAN 60.

  Further, as shown in FIG. 2, the seal stamp 20 is written with a seal portion 21 for stamping the document 10 on which the information 12 is printed by the printer 30 and a seal ID as second identification information unique to the seal stamp 20. The chip ID is read from the storage unit 22 and the RF-ID chip 11 inserted in the document 10, and the seal ID written in the storage unit 22 is written to the RF-ID chip 11 inserted in the document 10. An information reading unit 23 that reads the chip ID from the RF-ID chip 11 via the antenna 26, and a storage unit at the time of marking the document 10 at the marking unit 21. 22 is read by the information writing unit 25 and the information reading unit 23 which write the seal ID written on the RF-ID chip 11 via the antenna 26. And an information transmission unit 24 that transmits the ID together with the seal ID written in the storage unit 22. The chip ID and the seal ID transmitted from the information transmission unit 24 are managed via the wireless LAN 61 and the LAN 60. It is received by the server 40.

  In the management server 40, the chip ID database 51 in which the type of the document 10 in which the RF-ID chip 11 identified by the chip ID is inserted corresponding to each chip ID is registered, and the issuer of the document 10 The issuer ID database 52 in which the issuer information is registered corresponding to each of the chip IDs unique to the IC chip incorporated in the mobile phone 70 owned by the mobile phone 70, and the seal ID corresponding to each of the seal IDs A seal ID database 53 in which information on the owner of the seal is registered is managed.

  Hereinafter, a seal management method in the seal management system configured as described above will be described.

  First, processing when information 12 is printed on the document 10 by the printer 30 will be described.

  FIG. 3 is a flowchart for explaining processing when information 12 is printed on the document 10 by the printer 30 in the seal management system shown in FIG.

  When printing the information 12 on the document 10 with the printer 30, first, when the mobile phone 70 owned by the issuer of the document 10 is placed over the antenna 35 of the printer 30, A chip ID unique to the IC chip is read from the IC chip built in the mobile phone 70 by the information reading unit 32 via the antenna 35 (step S1). Since the chip ID read by the information reading unit 32 is unique to the IC chip built in the mobile phone 70, the issuer of the document 10 can be identified using this chip ID as the issuer ID. In the following description, the chip ID read from the IC chip built in the mobile phone 70 is referred to as an issuer ID.

  Next, the information 12 is printed on the document 10 in the printing unit 31 of the printer 30 (step S2).

  FIG. 4 is a diagram showing the document 10 on which the information 12 is printed by the printer 30 shown in FIG.

  As shown in FIG. 4, the printer 30 shown in FIG. 1 is provided with a stamping column 13 for marking, and the document 10 in which the RF-ID chip 11 is inserted in the stamping column 13 is provided. The information 12 determined for each type of the document 10 is printed in the print area 14 for printing information.

  Further, in the printing state in the printing unit 31, the antenna 34 of the printer 30 and the RF-ID chip 11 inserted into the document 10 are close to each other, thereby causing electromagnetic induction or electric wave due to current flowing through the antenna 34. The information reading unit 32 of the printer 30 reads the chip ID from the RF-ID chip 11 inserted into the document 10 via the antenna 34 (step S3).

  Next, in the information transmission unit 33 of the printer 30, the issuer ID read from the IC chip in the mobile phone 70 via the antenna 35 by the information reading unit 32, and the antenna 34 by the information reading unit 32. The chip ID read from the RF-ID chip 11 is transmitted (step S4). As a result, the issuer ID read from the IC chip in the mobile phone 70 is associated with the chip ID read from the RF-ID chip 11.

  The issuer ID and the chip ID transmitted from the information transmission unit 33 of the printer 30 are received by the management server 40 via the LAN 60 (step S5), and transmitted from the information transmission unit 33 in the management server 40. The issuer ID and the chip ID are managed in association with each other (step S6).

  FIG. 5 is a diagram for explaining the association between the issuer ID and the chip ID in the management server 40 shown in FIG.

  As shown in FIG. 5, in the management server 40, the issuer ID and the chip ID transmitted from the printer 30 are managed in association with each other. For example, the issuer ID “AAAAAAAAA” and the chip ID “11111111” are managed in association with each other, whereby the document 10 issued by the issuer identified by the issuer ID “AAAAAAAAA” has the chip ID “11111111”. It is managed that the RF-ID chip 11 is inserted.

  In this way, the management server 40 associates the document 10 on which the information 12 is printed by the printer 30 with its issuer.

  At this time, the information transmitting unit 33 may transmit information indicating the type of the document 10 printed by the printing unit 31 to the management server 40. In that case, the management server 40 uses the information indicating the type of the document 10 transmitted from the printer 30 together with the chip ID to determine the type of the document 10 in which the RF-ID chip 11 identified by the chip ID is inserted. It is conceivable to register in the chip ID database 51. The registration of the type of the document 10 in the chip ID database 51 is not limited to such processing, but the type of the document 10 in which the chip ID and the RF-ID chip 11 identified by the chip ID are inserted. It is also possible to register in advance in association with each other. In that case, after reading the chip ID from the RF-ID chip 11 inserted in the document 10 by the printer 30, the chip ID is transmitted to the management server 40, and the management server 40 transmits the chip ID from the printer 30. Printing information corresponding to the type of the document 10 registered in the chip ID database 51 in correspondence with the chip ID is transmitted to the printer 30, and the printing information transmitted from the management server 40 is printed by the printer 30. Conceivable.

  Next, processing when the stamp 20 is performed on the document 10 on which the information 12 is printed by the printer 30 will be described.

  FIG. 6 is a flowchart for explaining processing when the document 10 is stamped by the seal stamp 20 in the stamp management system shown in FIGS. 1 and 2.

  If the stamping section 21 of the stamp 20 is subjected to the stamping column 13 (see FIG. 4) of the document 10 on which the information 12 is printed by the printer 30 (step S11), the antenna 26 in the stamp 20 The RF-ID chip 11 encased in the document 10 is close to the RF-ID chip 11, so that the information reading unit 23 in the seal 20 receives the RF entrained in the document 20 by electromagnetic induction or radio waves caused by current flowing through the antenna 26. -The chip ID is read from the ID chip 11 via the antenna 26 (step S12).

  Then, the information transmitter 24 in the seal 20 transmits the chip ID read from the RF-ID chip 11 by the information reader 23 and the seal ID written in the storage unit 22 in the seal 20 ( Step S13). Here, a seal ID unique to the seal 20 is written in the storage unit 22 in the seal 20, and the seal 20 can be identified by this seal ID 20.

  The seal ID and the chip ID transmitted from the information transmitting unit 24 of the seal 20 are received by the management server 40 via the wireless LAN 61 and the LAN 60 (step S14). A search is made from the chip IDs managed in association with the issuer ID in S6 (step S15).

  Thereafter, the management server 40 manages the retrieved chip ID, the issuer ID managed in association with the chip ID, and the seal ID received together with the chip ID (step S16). .

  In the management server 40, the type of the document 10 in which the RF-ID chip 11 identified by this chip ID is associated with each chip ID in the chip ID database 51 is managed, and the issuer ID database 52, issuer information is managed corresponding to each issuer ID, and in the seal ID database 53, information on the owner of the seal stamp identified by this seal ID corresponding to each seal ID is stored. Therefore, it is possible to manage by which issuer the document 10 on which the information 12 has been printed by the printer 30 and by which stamper the document 10 has been stamped.

  In addition, when the document 10 is stamped by the stamping unit 21 and the antenna 26 in the stamp 20 and the RF-ID chip 11 inserted into the document 10 are close to each other, the information writing unit of the stamp 20 At 25, the seal ID written in the storage unit 22 is written into the RF-ID chip 11 via the antenna 26 (step S17). As a result, the stamp ID is read from the RF-ID chip 11 inserted into the document 10 to confirm that the stamper has actually performed the stamp on the document 10. At this time, the seal ID is written in the RF-ID chip 11 so that the chip ID already written in the RF-ID chip 11 is not erased.

  In this embodiment, the issuer ID read from the IC chip in the mobile phone 70 and the chip ID read from the RF-ID chip 11 are transmitted from the printer 30 and associated with each other in the management server 40. The issuer ID written in the IC chip in the mobile phone 70 and the chip ID written in the RF-ID chip 11 are associated with each other in advance by the management server 40 and managed. When the information 30 is printed on the document 10 by the printer 30, it is conceivable to read the chip ID from the RF-ID chip 11 inserted in the document 10 and transmit only this chip ID to the management server 40. In that case, the management server 40 recognizes that the information 12 is printed on the document 10 in which the RF-ID chip 11 in which the chip ID transmitted from the printer 30 is written is inserted.

(Second Embodiment)
FIG. 7 is a diagram showing a second embodiment of the stamp management system of the present invention.

  As shown in FIG. 7, the present embodiment is different from that shown in the first embodiment in that the information transmission unit 33 is not provided in the printer 130 and the information reading unit 32 is portable. An information writing unit 36 for writing the issuer ID read from the IC chip in the telephone 70 to the RF-ID chip 11 inserted in the document 10 is provided, and the printer 130 is connected to the management server 40. There is no stand-alone state.

  Hereinafter, a seal management method in the seal management system configured as described above will be described.

  First, processing when information 12 is printed on the document 10 by the printer 130 will be described.

  FIG. 8 is a flowchart for explaining processing when information 12 is printed on the document 10 by the printer 130 in the seal management system shown in FIG.

  When the information 12 is printed on the document 10 by the printer 130, first, when the mobile phone 70 owned by the issuer of the document 10 is put over the antenna 35 of the printer 130, The issuer ID is read from the IC chip built in the cellular phone 70 by the information reading unit 32 via the antenna 35 (step S21).

  Next, the information 12 is printed on the document 10 in the printing unit 31 of the printer 130 (step S22).

  In the printing state of the printing unit 31, the antenna 34 of the printer 130 and the RF-ID chip 11 inserted into the document 10 are close to each other, thereby causing electromagnetic induction or electric wave due to current flowing through the antenna 34. In the information writing unit 36 of the printer 130, the issuer ID read from the IC chip in the mobile phone 70 through the antenna 35 by the information reading unit 32 is written into the RF-ID chip 11 through the antenna 34. (Step S23). At this time, the issuer ID is written in the RF-ID chip 11 so that the chip ID already written in the RF-ID chip 11 is not erased.

  Thus, after the information 12 is printed on the document 10 by the printer 130, the issuer ID is read from the RF-ID chip 11 inserted in the document 10, thereby identifying the issuer of the document 10. it can.

  Next, a process when the seal is performed on the document 10 on which the information 12 is printed by the printer 130 will be described.

  FIG. 9 is a flowchart for explaining processing when the document 10 is stamped by the seal stamp 20 in the stamp management system shown in FIGS. 7 and 2.

  When the stamping section 21 of the stamp 20 is subjected to the stamping column 13 (see FIG. 4) of the document 10 on which the information 12 is printed by the printer 130 (step S31), the antenna 26 in the stamp 20 is connected. The RF-ID chip 11 encased in the document 10 is close to the RF-ID chip 11, so that the information reading unit 23 in the seal 20 receives the RF entrained in the document 20 by electromagnetic induction or radio waves caused by current flowing through the antenna 26. -The chip ID and the issuer ID are read from the ID chip 11 via the antenna 26 (step S32).

  Then, in the information transmission unit 24 in the seal stamp 20, the issuer ID and the chip ID read from the RF-ID chip 11 by the information reading unit 23 and the seal ID written in the storage unit 22 in the seal stamp 20 are obtained. It is transmitted (step S33).

  The issuer ID, the chip ID, and the seal ID transmitted from the information transmission unit 24 of the seal stamp 20 are received by the management server 40 via the wireless LAN 61 and the LAN 60 (step S34), and received by the management server 40. The issuer ID, chip ID, and seal ID are managed in association with each other (step S35).

  In the management server 40, the type of the document 10 in which the RF-ID chip 11 identified by this chip ID is associated with each chip ID in the chip ID database 51 is managed, and the issuer ID database 52, issuer information is managed corresponding to each issuer ID, and in the seal ID database 53, information on the owner of the seal stamp identified by this seal ID corresponding to each seal ID is stored. Therefore, it is possible to manage by which issuer the document 10 on which the information 12 has been printed by the printer 30 and by which stamper the document 10 has been stamped.

  In addition, when the document 10 is stamped by the stamping unit 21 and the antenna 26 in the stamp 20 and the RF-ID chip 11 inserted into the document 10 are close to each other, the information writing unit of the stamp 20 At 25, the seal ID written in the storage unit 22 is written into the RF-ID chip 11 via the antenna 26 (step S36). As a result, the stamp ID is read from the RF-ID chip 11 inserted into the document 10 to confirm that the stamper has actually performed the stamp on the document 10. At this time, the seal ID is written in the RF-ID chip 11 so that the issuer ID and the chip ID already written in the RF-ID chip 11 are not erased.

  In this embodiment, the printer 130 is in a stand-alone state not connected to the management server 40. However, as described in the first embodiment, the printer 130 is between the printer 130 and the management server 40. In order to exchange information indicating the type of the document 10 and print information, the printer 130 and the management server 40 may be connected via the LAN 60.

  Further, as a form of the seal 20 shown in the above-described two embodiments, the seal unit 21, the storage unit 22, the information reading unit 23, the information writing unit 25, and the antenna 26 are built in the mobile phone, The communication function is used as the information transmitting unit 24, and the seal unit including the stamping unit 21, the storage unit 22, the information reading unit 23, the information writing unit 25, and the antenna 26 is detachably attached to the mobile phone. It is also conceivable to configure the information reading unit 23 by connecting it to a communication unit of a mobile phone. In this case, the seal ID is not written in the storage unit 22 but is written in the memory in the mobile phone. When the seal ID is written in the RF-ID chip 11 of the document 10, the seal ID is stored in the mobile phone. It is also conceivable to give the information writing unit 25 from the internal memory. It is also conceivable that a switch is provided in the seal 20 so that a current is supplied to the antenna 26 by this switch only when a stamping operation is performed. Only when the operation is performed, information can be read from the RF-ID chip 11 inserted in the document 10 or information can be written to the RF-ID chip 11.

  In the two embodiments described above, the RF-ID chip 11 is inserted into the document 10. However, the method of attaching the RF-ID chip 11 to the document 10 is not limited to the insertion, and RF. -Various methods such as attaching the ID chip 11 to the document 10 are conceivable.

  Further, in the above-described two embodiments, when the seal 20 stamps the document 10, the information reading unit 23 of the seal 20 reads information from the RF-ID chip 11, and the read information is transmitted to the information transmitting unit 24. Are sent to the management server 40 via the wireless LAN 61 and the LAN 60, but the seal 20 is provided with a seal mode and a confirmation mode, and when performing the seal process as described above, the seal mode is set and the RF-ID chip 11 is set. It is also conceivable that information indicating that it is a stamping process is also added to the information read from, and transmitted from the seal stamp 20 to the management server 40. Further, when the seal stamp 20 is set to the confirmation mode, information indicating confirmation processing is added to the information read from the RF-ID chip 11 and transmitted from the seal stamp 20 to the management server 40. 2, it is possible to collate with the chip ID, issuer ID, and seal ID that are already managed in association with each other, and transmit the collation result to the seal 20.

  In the two embodiments described above, the seal ID written in the storage unit 22 is written in the RF-ID chip 11 inserted into the document 10 via the antenna 26 in the information writing unit 25. It is also conceivable that the seal 20 is not provided with the information writing unit 25 and the seal ID is not written on the RF-ID chip 11 inserted in the document 10.

  Further, in the two embodiments described above, when a plurality of stamp fields 13 are provided in the document 10, each of the plurality of stamp fields 13 is stamped. Even in that case, one RF-ID is also used. The chip 11 is inserted into the document 10, and the seal ID of the stamp 20 on which the seal is made is written in the stack method on the RF-ID chip 11 every time the seal is performed. If this is done, the history of the seal for the document 10 can be recorded. Even in this case, the information read from the RF-ID chip 11 and the seal ID are transmitted to the management server 40 every time the seal is performed.

  In the two embodiments described above, the chip ID is written in advance in the RF-ID chip 11. However, the method of assigning the chip ID to the RF-ID chip 11 is not limited to this, and the RF-ID chip is not limited to this. 11 does not have a chip ID written in advance, and when the printer 30 prints information on the document 10, the printer 30 makes an inquiry to the database in which the chip ID is registered, and an unused chip ID is assigned. Writing to the RF-ID chip 11 is also conceivable.
