  However, in the case of a gate device for managing confidential documents, if an electronic tag is assigned to each paper document for management, the attached electronic tags are bundled with RFID (Radio Frequency IDentfication) tags. In the case of a document, the tag interval approaches.

  And it is very difficult for RFID tags to read information from a plurality of tags that are close to each other with a tag interval of 1 mm or less, even if anti-collision technology is used, and it is assumed that a plurality of paper documents are overlaid. It is not suitable for document management.

  Further, it takes time to read information from each paper document, and a waiting time for passing through the gate device is required, which is not practical.

  In view of the above, an object of the present invention is to provide a gate device that manages the taking-out of different types of confidential documents depending on the person passing through the gate, assuming a security management system for paper documents provided with magnetic wires. To do.

  In order to achieve the above object, the invention according to claim 1 is characterized in that the gate device includes a passer attribute recognition means for recognizing a passer attribute of a passer who passes through the gate, and a document attribute of the document possessed by the passer. Generated based on a document attribute reading means for reading from a document, an AC magnetic field generating means for generating an AC magnetic field in the gate, and a magnetization reversal of a magnetic material applied to the document by an AC magnetic field generated from the AC magnetic field generating means Detection means for detecting the presence of the document based on the received signal, the passer attribute recognized by the passer attribute recognition means based on the detection output by the detection means, and the document attribute read by the document attribute reading means, And determining means for determining whether a passer possessing the document from the combination can pass through the gate.

  According to a second aspect of the present invention, in the first aspect of the present invention, the passer attribute recognition unit includes a radio reading unit that wirelessly reads the passer attribute from an identification information card carried by the passer, and the radio reading unit. Recognizing means for recognizing the passer-by attribute based on the read output of the means.

  According to a third aspect of the present invention, in the first aspect of the invention, the document attribute reading unit includes an optical reading unit that optically reads the document attribute from code information given to the document.

  According to a fourth aspect of the present invention, in the first aspect of the invention, the magnetic material applied to the document generates the signal by a large Barkhausen effect based on the application of the alternating magnetic field, and the detection means The presence of the document is detected based on the presence or absence of a signal.

  The invention of claim 5 further comprises alarm generation means for generating an alarm when the determination means determines that the passer cannot pass in the invention of claim 1.

  According to the first aspect of the present invention, it is possible to set and manage the types of confidential documents possessed by the passer and passing through the gate device for each passer attribute.

  According to the invention of claim 2, the passer attribute of the passer can be read remotely.

  According to the invention of claim 3, the document attribute information of the confidential document can be instantaneously read.

  According to the invention of claim 4, the existence of a confidential document can be read from a remote location.

  According to the invention of claim 5, it is possible to notify a person who has passed through the gate device that he / she must not pass through the gate device while holding the confidential document he / she has.

  Since each gate locally reads the passer attribute and the document attribute and makes a pass judgment, quick management becomes possible.

  This is because when the passage judgment is requested from the database server through the network, as the number of existing gates increases, the judgment takes time and the practicality is lowered.

  In addition, if the server goes down in an emergency, there is a risk of being unable to make a judgment.

  Embodiments of a gate device according to the present invention will be described below in detail with reference to the accompanying drawings.

  FIG. 1 is a configuration diagram showing an outline of a detection gate 100 which is a gate device according to the present invention.

  The detection gate 100 includes a passer-by attribute reading device 101, a confidential document detection device 102, a document attribute reading device 103, a determination device 104, and an alarm device 105.

  The passing person attribute reading device 101 supplies power to the RFID tag attached to the ID card 10 through electromagnetic waves, receives a signal emitted from the RFID tag, and records the passing person attribute recorded in the ID card 10. Receive information.

  Further, as shown in FIG. 1, the passer attribute reading device 101 is installed on both the side where the passer 30 enters the detection gate 100 and the side where the passer 30 exits, and the detection gate regardless of where the passer 30 enters or exits. 100 is configured to function (reference number 50).

  The ID card 10 records a passer attribute indicating how much confidential documents the passer 30 can take out, and all the passers 30 trying to pass through the detection gate 100 are recorded respectively. I have an ID card 10 on which different information is recorded.

  The passer attribute is assigned to all persons who may pass through the detection gate 100, and any one of the passer attributes A, B, and C is assigned to each person.

  The confidential document detection device 102 includes an excitation coil, a detection coil, and the like, and performs detection of the magnetic wire 21 applied to the confidential document 20 using the large Barkhausen effect.

  The document attribute reading device 103 is constituted by an optical reading device, and reads a document attribute from a bar code 22, a two-dimensional code, and a background pattern printed on the confidential document 20.

  In this embodiment, the document attribute is recorded by printing the barcode 22 on the confidential document 20, but the document attribute is recorded on the confidential document 20 with a two-dimensional code, a background pattern, or the like. May be.

  The document attribute is information indicating the importance level of the confidential document 20, and when the document content of the confidential document 20 is printed, it is a special ink that is difficult to distinguish with the naked eye such as normal ink or toner, or fluorescent ink or infrared absorbing material. A bar code 22, a two-dimensional code, a background pattern, and the like are recorded on the confidential document 20 by ink or toner made of material.

  When the special material is used, it is difficult to rewrite or change document attributes.

  The determination device 104 determines whether or not the passer 30 can pass while holding the confidential document 20 based on the information obtained from the passer attribute reader 101, the confidential document detection device 102, and the document attribute reader 103. I do.

  The determination device 104 includes a memory and serves as a reference for determining whether or not to prohibit passage from the passer attribute read from the passer attribute reading device 101 and the document attribute read from the document attribute reading device 103. A determination table 106 is provided in the memory.

  The alarm device 105 includes a speaker that is connected to the determination device 104 and can send an announcement. If the determination device 40 determines that the passer 30 should not pass while holding the confidential document 20, the alarm device 105 passes. An announcement is made that the person 30 should not pass.

  The warning method is not limited to the voice method as described above, and there is also a visual warning using a display element that displays the fact that it cannot pass by characters, symbols, or the like.

  This is because there is a possibility that work efficiency may be reduced by voice in the office.

  The confidential document 20 is provided with a magnetic wire 21 indicating that it is a confidential document.

  The magnetic wire 21 is a ferromagnetic material having a large Barkhausen effect made of an Fe—Co amorphous material, and is provided in a form that is inserted into the confidential document 20.

  The secret document 20 is generated by printing the document contents and the document attributes on a sheet provided with the magnetic wire 21.

  A bar code 22, a two-dimensional code, a background pattern, and the like are printed on the front surface of the confidential document 20 in order to record document attributes.

  The document attribute may be stored in the RFID tag by attaching an RFID tag to the document instead of printing the barcode 22 or the like on the document surface.

  When a large number (for example, five or more) of confidential documents 20 are generated, the document attribute is printed on the cover.

  When the RFID tag is used for recording the document attribute to the confidential document 20, the document attribute may be attached to the RFID tag attached to the cover of the large amount of confidential document 20, or a large amount of confidential document 20 may be closed to one folder, and a document attribute may be assigned to the RFID assigned to the folder.

  When an RFID tag is used for recording document attributes, the document attribute reading device 103 is a device that reads information on the RFID tags.

  When the passing person 30 possessing the confidential document 20 configured as described above enters the detection gate 100, the ID card 10 possessed by the passing person 30 is read by the passing person attribute reading device 101.

  When the document possessed by the passer 30 is the confidential document 20, the magnetic wire 21 attached to the confidential document 20 is detected by the confidential document detection device 102, and the passer 30 possesses the confidential document 20. Is detected.

  Then, the warning device 105 sends an announcement “Please let the document attribute reader read the document attributes of the document you have.”

  The passer 30 causes the document attribute reader 103 to read the barcode 22 in which the document attribute of the confidential document 20 possessed is recorded, and waits for the determination by the determination device 104.

  The determination device 104 has the passer attribute of the passer 30 obtained from the passer attribute reader 101 and the document attribute of the confidential document 20 obtained from the document attribute reader 103 by the passer 30 reading. It is applied to the determination table 106 to determine whether passage is permitted or prohibited.

  When the determination device 104 determines that the passage is prohibited, the alarm device 105 issues an announcement that “you cannot pass through this gate while holding the document”.

  In the detection gate 100 according to the gate device of the present invention, the rank of the confidential document 20 that can pass through the detection gate 100 while being possessed is determined according to the passer attribute of the passer 30 passing through the detection gate 100, and the determination is made. It is written in the table 106.

  Then, the take-out management of the confidential document 20 corresponding to the passer attribute of the passer 30 is performed by the detection gate 100.

  Next, the contents described in the determination table 106 will be described with reference to FIG.

  FIG. 2 is a diagram showing the contents described in the determination table 106, FIG. 2A is a table showing the contents of the determination table 106, and FIG. 2B is a diagram showing the contents of FIG. It is a schematic diagram which shows the content of the shown determination table.

  As shown in FIG. 2A, in the determination table, the contents of passer attribute, document attribute, and pass permission are described. There are three passer attributes, A, B, and C. There are two types of α and β depending on the level of confidentiality, and passage permission is permitted (◯) and prohibited (×).

  For example, a person whose passer-by attribute is A is allowed to pass all confidential documents (documents whose document attributes α and β are possessed), and a person whose passer-by attribute is B is a document attribute α. Passing with a document attribute β is prohibited, passing with a document attribute β document is permitted, and a person with passer attribute C is assigned to all confidential documents (document attributes α, β documents) of those documents. Passing in possession of is prohibited.

  As described above, the determination table 106 describes the document attributes of documents that are prohibited from passing and the document attributes of allowed documents according to the passer-by attributes.

  In addition, as shown in FIG. 2B, when the detection gate 100 is installed at the boundary between two rooms and the contents shown in FIG. 2A are set in the determination table 106 of the detection gate 100. Means that a person with passer attribute A is allowed to pass through detection gate 100 having documents with document attributes α and β, and a person with passer attribute B is only allowed to pass through detection gate 100 having documents with document attribute β. Thus, the detection gate 100 manages the person having the passer-by attribute C so that the passage through the detection gate 100 possessing the confidential document is prohibited regardless of the document attribute.

  Next, processing performed in the detection gate 100 will be described with reference to FIG.

  FIG. 3 is a flowchart showing a processing flow performed in the detection gate 100.

  In the detection gate 100, the passer attribute is read from the ID card 10 of the passer 30 by the passer attribute reading device 101 (step 301), and when the magnetic wire 21 is detected by the confidential document detection device 102 (step 301). Step 302), the determination device 104 determines whether or not to issue a signal prohibiting passage.

  The determination by the determination device 104 is performed according to the contents of the determination table 106 as shown in FIG.

  Here, according to the determination table 106 described with reference to FIG. 2, a person whose passer-by attribute is A (the passer-attribute is found in step 301) indicates that he has a confidential document. Even if the detected magnetic wire 21 is detected (step 302), the passage of all confidential documents is permitted, so the determination device 104 permits passage and sends a signal prohibiting passage to the alarm device 105. No (A in step 303).

  In addition, for a person whose passer-by attribute is C (passer-attribute is found in step 301), according to the determination table 106, passage of possession of all confidential documents is prohibited. When the detection is performed, the determination device 104 sends a signal prohibiting passage of the passer 30 to the alarm device 105, and an announcement that “the document cannot be passed while being carried” is sent from the alarm device 105. , Passage is prohibited (C in step 303, step 304).

  For a person whose passer-by attribute is B (the passer-by attribute is found in step 301), the alarm device 105 reads “Please let the document attribute reading device read the document attribute of the possessed document”. (Step 305), the document attribute reader 103 is made to read the document attribute of the confidential document 20 possessed by the passer 30.

  When the document attribute is read by the document attribute reading device 103 (step 306), the determination device 104, based on the read document attribute, the confidential document 20 possessed by the passer 30 (passer attribute B in this case). If the document attribute of the confidential document 20 is α (YES in step 307), the person with the passer-by attribute B cannot take out the document with the highly confidential document attribute α. If the document attribute of the confidential document 20 is β (NO in step 307), a signal prohibiting passage and prohibiting passage is not sent. .

  If YES in step 307 and a signal prohibiting passage is sent to the alarm device 105, the alarm device 105 will announce that “this gate cannot be passed while holding the document” (step 308). In addition, passage of the passerby who possesses the confidential document 20 having the document attribute α (passer attribute is B) is prohibited.

  Here, in order to guarantee the above process, it is necessary that the attributes of all documents possessed by the passers are read by the document attribute reader 103.

  For example, if a person with the passer-by attribute B has a document with the document attribute α and a document with β, it is assumed that only the β document is read and passed.

  Hereinafter, an example of a method in which the attributes of all the documents possessed by the passing person are read by the document attribute reading device 103 will be described.

  When the document attributes are stored in the RFID tag, it is possible to read all from the outside of the gate using the RFID tag having a long communication distance.

  Here, let us consider a case in which attributes are read by the document attribute reading device 103 installed in the gate detection area.

  If a passer-by detects all of the documents held by the document attribute reader 103 and the magnetic wire continues to be detected, the passer-by determines that the confidential document is concealed. Please receive "message.

  If the passing person puts all possessed documents into the document attribute reading device 103 and the detection of the magnetic wire disappears, it is determined that all the documents have been placed, and reading starts.

  A person skilled in the art can come up with various mechanisms for preventing the signal from the magnetic wire in the confidential document input to the document attribute reader 103 from being detected.

  For example, when the input of a document is detected, there is a method of sufficiently weakening the magnetic field of the gate on the side where the document attribute reading device 103 is attached and detecting the document hidden by the gate on the opposite side.

  Or a method of temporarily moving the input document to the area where the magnetic field of the gate on the side where it is attached does not reach, or an area where the signal from the magnetic wire in the input document is temporarily not output By the method of moving to, it is possible to detect a document concealed by a passerby by the gate on the side where the document attribute reading device 103 is attached and the gate on the opposite side.

  If the magnetic gate 21 is not detected in the detection gate 100, it is determined that the passer 30 does not have a confidential document, and the passage is permitted. Not sent.

  Next, the security management between the rooms of the confidential document 20 will be described with reference to FIG. 4 by installing the detection gate 100 at the entrance of each room among the plurality of rooms.

  FIG. 4 is a schematic diagram showing security management between rooms of the confidential document 20.

  As shown in FIG. 4, there are three rooms a-401, b-402, and c-403, and a detection gate 100-1 is installed between the room a-401 and the room b-402. The detection gate 100-2 is installed between the room b-402 and the room c-403, and the detection gate 100 is provided between the room a-401 and the outside, and between the room c-403 and the outside. -3 is installed.

  The detection gates 100-1, 100-2, and 100-3 all have the same configuration and the same function as the detection gate 100, but the contents set in the determination table 106 are different.

  In this way, by changing the contents set in the determination table 106 of the detection gate 100 installed at each entrance of a plurality of rooms, the attributes of the confidential documents that can be moved and moved between rooms are the same person. But it can be different.

  For example, as shown in FIG. 4, a person having any passer attribute outside the room a-401 cannot carry the confidential document 20 and pass through the detection gate 100-3.

  In addition, as shown in FIG. 4, in a room a-401 to a room b-402, a person having a passer-by attribute A has a confidential document 20 with document attributes α and β and has a detection gate 100-1. A person who has a passer attribute B can pass, but is prohibited from passing the detection gate 100-1 with the confidential document 20 having the document attribute α, and possessing the confidential document 20 having the document attribute β. In addition, the person having the passer attribute C can be prevented from passing through the detection gate 100-1 possessing the confidential document 20, regardless of the document attribute.

  In addition, as shown in FIG. 4, in a room b-402 to a room c-403, a person having a passer-by attribute A has a confidential document 20 with document attributes α and β and has a detection gate 100-2. A person who has a passer attribute B and a passer attribute C is allowed to pass through the detection gate 100-2 possessing the confidential document 20 regardless of the document attribute.

  In addition, as shown in FIG. 4, a person having any passer attribute from the room c-403 cannot pass the detection gate 100-3 with the confidential document 20.

  Thus, by setting the contents of the determination table 106 in various ways, it is possible to use a security document in a different space for each passerby (person), and flexible security document management is performed.

  In addition, the movement of the gates except for the detection gate 100-3 located at the boundary with the outside is made free, and the movement of the confidential documents between the rooms is made to correspond to the attributes of the passers by following the passage log at each gate. Can also be tracked.

  In addition, when an opening / closing type passage gate that prevents passage of people is set in the detection gate 100 and the determination device 104 determines that passage is prohibited, the alarm device 105 notifies the user and closes the passage gate. The passer 30 may be prohibited from passing.

  The present invention can be used in a gate device that detects an object to be detected.

  According to the present invention, traffic management is performed with different types of confidential documents depending on the types of passers passing through the gate device.
