Description

  The present invention relates to a vault management system, a vault management method, a biometric authentication system, and a vault that have a plurality of authentication methods.

  Conventionally, facilities that require a high level of security such as vaults and research institutions of financial institutions, cash handling equipment such as ATMs (automated teller machines) and vending machines, etc., enter the facilities and open doors. Strict personal authentication is performed when the door is opened to improve internal and external theft protection.

  For example, Patent Document 1 below proposes a safe equipped with a cylinder lock that is unlocked with a key and a dial lock that is unlocked by turning a dial to match several digits. Further, this Patent Document 1 also discloses that an automatic unlocking signal is output to the dial lock by the user's fingerprint authentication to reduce the rotation operation of the dial lock (claim 8, paragraph 0082, FIG. 12). .

  Patent Document 2 discloses a configuration in which an external door unlocks a cylinder lock with a key and an internal door is unlocked by a fingerprint authentication device that collates an operator's fingerprint in an ATM or a vending machine. Further, this Patent Document 2 proposes to record unlocking history data such as the ID and date / time of the operator who unlocked the internal door and to output it to an external host device (claim 4, paragraph). 0039, 0040, 0053, 0054, FIG. 4).

  Next, Patent Document 3 discloses an apparatus that records biometric information of a plurality of persons on an IC card and provides different transaction contents depending on the number of authenticated persons when operating an ATM or a safe. Yes. For example, when issuing a cash card with an IC, it is possible to set biometric information of a plurality of people and transaction limits (such as 300,000 yen and 10 million yen) that are different for each authenticated person and record them on the card. it can. Thereby, when any user is involved in a crime, damage can be minimized. Further, by applying to management of confidential information in a medical institution, information leakage can be prevented (claims 1 to 3, paragraphs 0012 to 0014, etc.).

JP 2000-179202 A (Claim 8, paragraph 0082, FIG. 12) JP 2003-232154 A (Claim 4, paragraphs 0039, 0040, 0053, 0054, FIG. 4) JP 2008-112231 A (Claims 1-3, paragraphs 0012-0014, etc.)

  Generally, authentication methods using biometric information such as fingerprints, irises and veins are much more secure than authentication methods using numbers such as passwords or dial locks because there is no risk of information leakage and forgery is difficult. Is expensive. The above-described conventional techniques are common in that security is maintained and improved by authentication based on biometric information.

  However, the biometric authentication system includes an electronic device such as a scanner, a microcomputer, and a host computer, and a data transmission path that connects the devices in any of reading (scanning) of biometric information and verification with registered biometric information. It is essential. If any of these facilities become impossible due to breakdown, crime, disaster, etc., enormous costs and labor are required to take out cash and important documents in the safe. In particular, in a financial institution, if the biometric authentication system is disabled during business hours, it is impossible to withdraw cash from the safe, and many business operations must be stopped. In addition, the doors and vaults of safes in financial institutions have a robust structure with advanced fire resistance, earthquake resistance, crime prevention, etc. A huge amount of money and labor is required.

  Further, even when there is no unlocking authority with which biometric information is registered, there is a risk that business may be hindered as described above. This point can be avoided by registering multiple unlocking authorities and managing so that at least one of them is always present, but it can be expected even in the event of an emergency such as a crime, disaster, or loss of transportation. Management is very difficult.

  The present invention has been made in order to solve the above-described problems. In combination with a plurality of unlocking methods including a unlocking method with a high security level such as biometric authentication, the present invention can be used to maintain a high level of security and prevent fraud. An object of the present invention is to provide a safe lock management system, a safe room management method, a biometric authentication system, and a safe room that can be used in an emergency while preventing.

  In order to solve the above-described problems, in a main aspect of the present invention, a locking mechanism that locks an openable / closable safe door installed in an opening of a safe room, and the locking mechanism can be unlocked, A first unlocking mechanism set as an unlocking means and a second unlocking mechanism set as an emergency unlocking means can be unlocked independently of the first unlocking mechanism. A lock mechanism, unlocking information receiving means for receiving unlocking information unlocked by the first or second unlocking mechanism from the locking mechanism, and a safe door by the second unlocking mechanism. When receiving unlocked unlocking information, a lock management system for a safe provided with an unlocking history storing means for storing unlocking history information and a safe room equipped with this system are provided.

  Further, according to a different aspect of the present invention, a first unlocking mechanism that can be unlocked and set as a normal unlocking means, and the first unlocking mechanism, which can unlock the safe door of the safe room, Receiving the unlocking information unlocked by any one of the second unlocking mechanism set as an emergency unlocking means capable of unlocking the locking mechanism independently, and And a safekeeping management method comprising: storing unlocking history information in a storage medium when receiving unlocking information in which the safe door is unlocked by the second unlocking mechanism. Provided.

  In another different aspect of the present invention, biometric information storage means for storing biometric information of a user who has the authority to unlock the safe door of the safe room, and when the unlocker unlocks the safe door, When biometric information acquisition means for acquiring biometric information of the locker, authentication means for authenticating the unlocker by comparing the stored biometric information with the biometric information of the unlocker, and when the unlocker is authenticated And an unlocking instruction means for sending an unlocking instruction command to the locking mechanism of the safe door, and when the safe door is unlocked by a method other than biometric authentication, unlocking information is received from the locking mechanism of the safe door. There is provided a biometric authentication system including an unlocking history storage unit that acquires and stores as unlocking history information.

  According to the present invention, during normal times, for example, unauthorized unlocking from inside and outside is effectively prevented by an unlocking method with a high security level such as biometric authentication. If it is, the unlocking history information is stored so that the illegal act can be easily searched. Even when the first unlocking mechanism becomes unusable due to a failure or the like, the safe can be unlocked by an unlocking mechanism of a different type from the first unlocking mechanism such as a dial type. Accordingly, it is possible to obtain a safe lock management system, a safe room management method, a biometric authentication system, and a safe room that can cope with an emergency while maintaining security.

Similarly, it is a functional block diagram which shows the structure of a locking management system. It is a flowchart which shows the unlocking process by the 1st unlocking mechanism among the lock management methods of the safe which concerns on embodiment of this invention. It is a flowchart which shows the unlocking process by the 2nd unlocking mechanism among the lock management methods of the safe which concerns on embodiment of this invention.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
FIG. 1 is a diagram showing an overview of a safe lock management system 1 according to the present embodiment installed in a branch 3 of a financial institution 2. The locking management system 1 includes a locking mechanism 6 that locks an openable / closable safe door 5 installed in an opening 4A in front of the safe room 4, and first and second unlocking mechanisms that can unlock the locking mechanism 6. 7 and 8. The main parts of the first and second unlocking mechanisms 7 and 8 are arranged on the safe door 5 or its periphery. The lock management system 1 is connected to an administrator computer (PC) 9 in the branch 3 and a host computer 10 in the security department in the head office or bank via a network NW1 such as a LAN or WAN. Further, if necessary, it can be connected to an external security company or an external organization 11 such as the police via the external network NW2.

  The vault 4 is installed in a corner of the branch 3 store, and the side walls, the floor, the ceiling structure, and the safe door 5 installed in the opening 4A are fireproof, seismic, waterproof, and anti-theft, respectively. It has an excellent structure. For example, the side wall of the vault 4 is composed of a concrete wall of 300 mm or more in which metal reinforcing materials are filled at a high density. The safe door 5 is configured by a door having a thickness of 300 mm or more in which a surface material such as an iron plate or an alloy of 10 mm to several tens mm is integrated with a refractory material filled in an internal space.

  In addition, an emergency second opening 4B (emergency exit) is provided on one side of the safe room 4, and a safe door, a locking mechanism, and the like are also installed in the emergency exit 4B. The configuration of the second safe door 50 etc. of the emergency exit 4B will be described later.

  In the present embodiment, the safe door 5 has a double structure of an outer main door 5A and an inner lattice door 5B. The lattice door 5B is provided with a cylinder lock 12 and an opening / closing lever 13 that are unlocked with a key. Usually, in order to save the trouble of repeatedly opening and closing the main door 5A during the business hours of the branch 3, the main door 5A is always unlocked and only the lattice door 5B is locked. Since the structures of the safe room 4 and the safe door 5 are well known in the art, further detailed description is omitted. In the following description, the door 5A will be described as the safe door 5 unless otherwise specified.

  Next, the configuration of each part of the locking management system 1 will be described in detail with reference to the functional block diagram of FIG.

  First, the locking mechanism 6 of the safe door 5 is built into the safe door 5 so as to be able to move in and out, and a lock plate (閂) for fixing the free end of the safe door 5 and the structure (front wall) of the safe 4 opposite to the free door. 20 and a regulating mechanism 22 that mechanically regulates the operation of the round handle 21, the lock plate 20 and / or the round handle 21 that causes the lock plate 20 to be moved in and out of the safe door 5 when the unlocker manually rotates. The controller 23 for electronically controlling the operation of the regulating mechanism 22 has a well-known configuration integrated with the safe door 5. The safe lock 5 (the main door 5A) may be provided with the same cylinder lock as the lattice door 5B.

  Specifically, the lock plate 20 is configured by a flat plate such as a rectangular shape, an L shape, or an inverted L shape that is built in the safe door 5, and a long side end portion extends from the free end of the safe door 5. It is configured to appear and disappear (see FIG. 1). As shown in FIG. 1, a door frame 24 is fixed around the opening 4 </ b> A of the safe room 4, and an engagement extending in the vertical direction on the surface of the door frame 24 facing the free end of the safe door 5. A groove (not shown) is formed. At the time of locking the safe door 5, the unlocker (locker) operates the round handle 21 to advance the front end of the lock plate 20, and fits into the engagement groove of the door frame 24. 5 can be firmly fixed to the structure (front wall) of the safe 4. The lock plate 20 and the door frame 24 are preferably formed of the same high strength alloy as the surface material of the safe door 5. The lock plate 20 can be changed to a plurality of lock bars having a diameter of about several tens of millimeters arranged side by side in the vertical direction on the side surface of the free end of the safe door 5.

  The restricting mechanism 22 includes a restricting member such as a lock pin or a hook that restricts the advance operation of the lock plate 20 or the rotation of the round handle 21 and a motor that moves the restricting member. For example, the lock plate is inserted by inserting a lock pin into one or a plurality of engagement holes formed in the lock plate 20 or by engaging a hook with an engagement piece integrated with the rotary shaft of the round handle 21. 20 or the operation of the round handle 21 is restricted. Further, when releasing the restriction, the restriction member is rotated, slid or retracted by the motor. In addition, since the regulation mechanism 22 is built in the safe door 5 having a robust structure and is blocked from the outside, mechanical and structural strength is not required for itself.

  The controller 23 releases the restriction by driving the motor of the restriction mechanism 22 in accordance with the unlocking instruction signal transmitted from the first or second unlocking mechanism 7 or 8. In addition, after releasing the restriction mechanism 22, the controller 23 sends an unlock notification signal (unlock information) to the first unlocking mechanism 7 via a control box 37 described later. This unlock notification signal includes an identification code for identifying which of the first or second unlocking mechanisms 7 and 8 has unlocked.

  In the present embodiment, the controller 23 is provided with a notification function that, when unlocked by the second unlocking mechanism 8, is regarded as abnormal unlocking and issues an alarm to the administrator PC 9 or the like (notification means). Specifically, the notification function is configured to generate sound, light, and light when an unlocking command is received from an unlocking instruction unit 44 (to be described later) of the second unlocking mechanism 8 and unlocked (the restriction mechanism 22 is released). This is a function for transmitting an output instruction signal to an output device capable of outputting text, vibration, and the like. The output device includes, for example, a display or built-in speaker connected to the administrator PC 9 or the host computer 9 of the head office, a display installed around the safe door 5 or the safe room 4 or in the store, a speaker, a lighting fixture or an indicator, A display such as a mobile phone carried by the administrator, a speaker, or a vibrator is included.

  With this notification function, it is possible to immediately notify the administrator or the like that the safe door 5 has been unlocked by the second unlocking mechanism 8 and to detect fraud at an early stage. Will improve. As the second unlocking mechanism 8, a mechanism having a relatively low security level or anti-theft property and / or a locking mechanism different from the first unlocking mechanism 7 compared to the first unlocking mechanism 7. A mechanism capable of unlocking 6 (electronic lock, dial lock, cylinder lock, numeric keypad, magnetic lock, etc.) is employed. Note that the notification conditions may include that the first unlocking mechanism 7 is disabled, that the administrator or the like has previously set notification (no notification is not set), and the like. In the former case, it is preferable that the controller 23 confirms the operating state by transmitting / receiving a confirmation signal to / from the first unlocking mechanism 7. In the latter case, the notification condition is preferably stored in the internal memory of the controller 23 or the like.

  Next, the first unlocking mechanism 7 is set as a normal unlocking means of the locking mechanism 6 of the safe door 5. In the present embodiment, the first unlocking mechanism 7 is configured by an unlocking mechanism using biometric authentication. Yes. Here, “normal unlocking means” refers to an unlocking mechanism that is regarded as a normal unlocking, and unlocking by other unlocking mechanisms (second unlocking mechanism 8) is “abnormal opening. "Lock" and "emergency unlock". In the following description, it will be referred to as “biometric authentication lock 7”. In addition, the conventionally well-known biometric authentication lock is corresponded to the concept which combined the biometric authentication lock 7 and the locking mechanism 6 of this embodiment.

  The biometric authentication lock 7 is configured by a small computer in which an input / output device or the like is connected to a processor or a memory (storage medium). Specifically, the biometric authentication lock 7 includes a biometric information storage unit 30, a card reader 31, a biometric information acquisition unit 32, an authentication unit 33, an unlocking instruction unit 34, a history storage necessity determination unit 35, and an unlocking history storage. Means 36 are provided. The structure of hardware and software (including interfaces) used for biometric authentication conforms to international standards such as BioAPI (Biometric Application Programming Interface), ISO / IEC, and CBEFF (Common Biometric Exchange Formats Framework). is doing.

  The biometric information storage means 30 includes biometric information (fingerprints, irises, finger and palm veins, voiceprints, etc.) of users who have authority to unlock the safe door 5 (managers such as branch managers, section managers, security personnel, etc.) This is a storage area in a storage medium for storing feature data or the like in association with personal identification information, authority type, or the like. In the present embodiment, the biological information storage means 30 is provided in a portable storage medium 38 held by the unlocker, for example, an IC card. As a result, it is not necessary to centrally manage enormous information such as biometric information, personal information, and authority information of the unlocking authority, and a simple biometric authentication system that does not depend on the network environment or the like can be realized. In the following, an example in which fingerprint feature data is used as biometric information will be described.

  The card reader 31 has a conventionally known configuration that reads biometric information stored in a card in a contact / non-contact manner from a storage medium presented by an unlocker (user).

  The biometric information acquisition means 32 is a known fingerprint scanner as an input device that scans the unlocker's finger in contact with the reading surface to acquire fingerprint image data when the unlocker unlocks the safe door 5. It is.

  The authentication unit 33 is an image processing program stored in a storage medium, and has a function of comparing the fingerprint data read by the card reader 31 with the fingerprint data of the unlocking person to determine whether the unlocking is possible. Specifically, the authentication unit 33 includes tens to hundreds of feature points such as the center point, branch point, end point, and delta of the fingerprint from the image data of the fingerprint of the unlocker acquired by the biometric information acquisition unit 32. The feature points of the fingerprint of the unlocking authority extracted and read by the card reader 31 are compared and collated with respect to the type, orientation, coordinates from the center point, etc., and it is determined whether they are the same person.

  The unlocking instruction unit 34 is a program stored in a storage medium, and when the authentication unit 33 determines that the person is the same person (can be unlocked), the safe door via the control box (release instruction notifying unit) 37. 5 has a function of sending an unlocking instruction command to the locking mechanism 6. Here, the control box 37 is an electronic device that converts the unlocking instruction command sent from the unlocking instruction unit 34 into an unlocking signal of the locking mechanism 6.

  The history storage necessity determination unit 35 is a program stored in a storage medium. When the unlocking notification is received from the locking mechanism 6 via the control box 37, the first or second unlocking mechanism 7, 8 is stored. It has the function to determine which was unlocked. Specifically, when the unlocking mechanism identification code is extracted from the unlocking notification signal transmitted from the controller 23 of the locking mechanism 6 to identify the unlocking mechanism, and when the second unlocking mechanism 8 unlocks it. Judge that it is necessary to save the unlocking history.

  Here, all unlocking histories including the biometric authentication lock 7 can also be stored. In this case, the history storage necessity determination means 35 only specifies the unlocking mechanism, and does not determine the necessity of storage.

  Further, the unlocking history can be stored only when the biometric lock 7 is not possible due to a failure or disaster, or when designated by the administrator. In this case, a flag indicating that the biometric authentication lock 7 is usable / unusable and that the administrator has designated the history storage is registered in the memory of the biometric lock 7 in advance. The history storage necessity determination unit 35 refers to the memory to determine whether the unlocking history needs to be stored according to the presence or absence of the flag when the unlock notification signal includes the identification code of the second unlocking mechanism 8. .

  The unlocking history storage means 36 is a storage area in a storage medium built in the biometric authentication lock 7, and the safe door 5 is unlocked by a method other than biometric authentication (second unlocking mechanism 8), and history storage is performed. When the necessity determination means 35 determines that the history needs to be stored, the date and time when the unlock notification signal is acquired from the locking mechanism 6 is stored as unlock history information (log), for example, in CSV format. When all unlocking histories including unlocking by the biometric authentication lock 7 are stored, the identification code of the locking mechanism is also stored. By recording an abnormal unlocking history by the second unlocking mechanism 8, the presence or absence of unauthorized unlocking can be verified later. In addition, by making such management of unlocking history known to bank employees and third parties, it is possible to prevent fraud from psychologically. Since the management of the unlocking history does not necessarily require real-time property, it may be transmitted to the host computer 10 in the head office or data center for centralized management.

  The biometric authentication lock 7 has a history storage function (history storage necessity determination means 35) even when the unlocking function unit (biological information acquisition means 32, authentication means 33, control box 37, signal transmission path, etc.) is impossible due to force majeure. In addition, it is preferable that the data transmission path, the control system, and the like are configured independently by both functional units so that the unlocking history storage means 36) is effective.

  The second unlocking mechanism 8 can unlock the locking mechanism 6 independently of the biometric authentication lock 7, and is set as an emergency unlocking means. That is, when unlocking the locking mechanism 6, it is not necessary that the unlocking conditions of both the biometric authentication lock 7 and the second unlocking mechanism 8 are met, and even the unlocking conditions of any of the unlocking mechanisms 7, 8. Just align. Therefore, even when the biometric authentication lock 7 is functioning effectively, the locking mechanism 6 can be unlocked by the second unlocking mechanism 8.

  Here, “emergency unlocking means” means that when the locking mechanism 6 is unlocked, the unlocking mechanism is always regarded as “abnormal unlocking” or “emergency unlocking”. . As described above, not only when the biometric authentication biometric lock 7 is functioning normally, but also when the biometric lock 7 cannot be unlocked due to a failure or the like and can be unlocked only by the second unlocking mechanism 8. However, when the second unlocking mechanism 8 unlocks, it is determined as “abnormal unlocking”, and the unlocking history is registered.

  The second unlocking mechanism 8 in the present embodiment is a known dial type electronic lock (code lock) that sends an unlocking command to the locking mechanism 6 when a plurality of input numbers match the unlocking number. It is. In the following description, it will be referred to as “dial lock 8”.

The dial lock 8 includes an unlocking number storage unit 40 that stores a plurality of preset unlocking numbers, and a cylindrical operation dial that is exposed on the front surface of the safe door 5 and that the unlocker rotates in the forward and reverse directions. (Input means) 41, a number reading unit 42 for recognizing the reference position number N and the rotation direction D in a state where the operation dial 41 is stopped for a predetermined time (for example, 3 seconds or more) after the operation is started, and the number verification unit 43 reads A number collation unit 43 for collating numeric data (N _n D _n O _n ) including the number N, direction D and input order O with the unlocking number of the unlocking number storage unit 40, and a predetermined number of numeric data (N ₁ And D ₁ O _{1 to} N _n D _n O _n ) are provided, and an unlocking instruction unit 44 that determines that unlocking is possible and sends an unlocking command to the locking mechanism 6 is provided. The unlocking number is usually set to n (for example, n ≧ 4) in which 1 or 2 digits displayed on the operation dial 41, the dial rotation direction, and the input order are combined, and the combination of inputs is Tens of millions to hundreds of millions. Note that each time the number reading unit 42 reads a number, the number collating unit 43 collates the number, and the processing may be terminated when they do not match.

  The dial lock 8 can be constituted by a small computer in which an input / output device or the like is connected to a processor or a memory (storage medium). The unlocking number storage unit 40 and the number storage unit 43 are storage areas of the storage medium, the operation dial 41 and the number reading unit 42 are input devices, the unlocking instruction unit 44 and the control of each unit are a program stored in the storage medium, Each is composed of a processor. In addition, the conventionally well-known dial type electronic lock corresponds to a concept in which a part of the locking mechanism 6 and the dial lock 8 in the present embodiment is combined.

  As described above, the second opening 4B (emergency exit) having an opening area smaller than the front opening 4A is provided on one side surface of the safe room 4. This emergency exit 4B is safe due to a disaster or failure. When the safe door 5 at the front of the room becomes unlocked, it is used for entering and exiting the safe room. In the emergency exit 4B, the second safe door 50, the second locking mechanism 60 that locks the second safe door 50, and the third and fourth locks that can unlock the second locking mechanism 60 independently. The unlocking mechanisms 70 and 80 are installed. Since the configuration of each part is the same as that of the safe door 5 and the locking mechanism 6 described above, repeated description is omitted.

  Accordingly, even in the safe door 50 of the emergency exit 4B, the unlocking history is stored when unlocked by the dial type fourth unlocking mechanism 70. Here, the unlocking history of the fourth unlocking mechanism 70 is stored in the unlocking history storage means 36 of the first unlocking mechanism (biometric authentication lock) 7 or the second unlocking mechanism 70 in the biometric authentication lock 7. A lock history storage means can be provided and stored. In the former case, it is preferable to include the identification information of the safe doors 5 and 50 in the unlocking history information (log).

  Next, processing steps of the locking management method according to the embodiment of the present invention using the above-described locking management system 1 will be described with reference to the flowcharts of FIGS. 3 and 4. Below, the unlocking pattern at the normal time (FIG. 3) unlocked by the biometric lock 7 and the unlocking pattern at the time of abnormal unlocking by the dial lock 8 (FIG. 4) will be described separately. Note that illustration and description of well-known processing steps not related to the present invention, such as re-locking after unlocking and releasing the time lock, are omitted.

  First, as shown in FIG. 3, when unlocking with the biometric authentication lock 7, when the unlocker inserts the IC card 38 into the card slot, the card reader 31 receives the fingerprint data from the biometric information storage means 30 in the card. Read and temporarily store in the memory (S1). Next, when the unlocking person holds his / her finger over the reading surface, the biometric information acquisition means 32 scans the reading surface to acquire image data of the unlocking person's fingerprint and temporarily stores it in the memory (S2). Next, the authentication unit 33 extracts feature points from the fingerprint image data and collates with the fingerprint data read from the card (S3).

  If the fingerprint data match (Yes in S4), the authentication unit 33 determines that the unlocking is possible and transmits an unlocking instruction to the control box 37 (S5). On the other hand, if the fingerprint data does not match (No in S4), an error sound or voice message is output until the set number of trials (for example, 3 times) is reached, and the unlocker is prompted to input again (S6, S7). ). If the fingerprint data does not match even if the number of trials is reached (Yes in S6), a message for ending the processing is output, the acquired fingerprint data and the number of trials are erased from the memory, and the unlocking process is terminated. In addition, from the viewpoint of fraud prevention, such a history that cannot be verified may be recorded.

  The control box 37 converts the unlocking instruction received from the authentication means 33 into a readable signal (unlocking instruction signal) of the locking mechanism 6 and transmits it to the locking mechanism 6 (S8). The controller 23 of the locking mechanism 6 drives the motor of the restriction mechanism 22 to release the restriction of the round handle 21 and the like by the restriction member (S9). At this time, it is preferable to output a sound or an optical signal from a speaker or a lock / unlock indicator installed around the safe door 5 to notify the unlocker of the release of the restriction. The unlocker rotates the circular handle 21 to retract the lock plate 20 into the safe door 5, opens the safe door 5 (main door 5A), and uses a portable cylinder key to check the lattice door. 5B can be opened to enter safe room 4.

  Further, when receiving the unlocking instruction signal transmitted from the control box 37, the controller 23 determines which unlocking mechanism 7 or 8 is the signal (S10). Here, since the transmission path is connected to the control box 37, it is determined that the unlocking instruction is issued from the biometric lock 7. Note that the unlocking instruction signal may include identification information of the unlocking mechanism.

  When it determines with it being unlocking by the dial lock 8 (Yes of S11), the controller 23 considers it as abnormal unlocking and transmits an alarm instruction | indication signal to output devices, such as administrator PC9 (S12). The output device that has received the warning instruction signal notifies the alarm in a preset format such as voice, light, or message (S13). On the other hand, when it is determined that the unlocking is performed by the biometric lock 7 (No in S11), S12 and S13 are skipped and the process proceeds to S14.

  In S <b> 14, the controller 23 generates unlocking information including the identification code of the unlocking mechanism determined in S <b> 10 and transmits it to the control box 37. The control box 37 converts the received unlocking information into an unlock notification signal decipherable by the biometric lock 7 and transmits it to the biometric lock 7 (S15).

  In the biometric authentication lock 7, the history storage necessity determination means 35 receives the unlocking information (unlocking notification signal) transmitted from the control box 37, and extracts the unlocking mechanism identification code included in this signal, It is determined which unlocking mechanism is used for unlocking (S16). When unlocked with the dial lock 8 (Yes in S17), the history storage necessity determination means 35 further determines whether the unlocking history information needs to be stored in accordance with other conditions such as the biometric lock 7 being unusable. Determine (S18).

  When it is determined that it is necessary to save the unlocking / unlocking information (Yes in S18), the date and time when the unlocking / unlocking information is received is obtained from a real time clock (not shown) and stored in the unlocking history storage means 36 (S19). ). As a result, a series of processing ends. When the unlocking is performed by the biometric authentication lock 7 (No in S17) and when it is determined that the unlocking history is not required to be stored (No in S18), the subsequent steps (S18, S19) are skipped. finish. Note that the unlocking person's fingerprint data acquired in S2 is stored in the memory at the time when the unlocking instruction is sent to the locking mechanism 6 (S5), when the unlocking history information is stored (S19), or at any other time. Erase from

  Next, with reference to FIG. 4, processing steps when the locking mechanism 6 is unlocked by the dial lock 8 will be described.

First, when the unlocker rotates the operation dial 41, the number reading unit 42 starts monitoring whether the operation dial 41 stops for a predetermined time. When the operation dial 41 stops for a predetermined time, the number reading unit 42 reads the number F ₁ and the rotation direction D ₁ of the dial at the reference position, and sends them to the number matching unit 43 together with the input order O ₁ (S21). The number collation unit 43 collates the acquired numeric data (O ₁ F ₁ D ₁ ) with the unlock number in the unlock number storage unit 40 (S22).

If they match (Yes in S23), the collation result is sent to the unlocking instruction unit 44. Unlocking instruction unit 44, the input order O _N of the matched numerical data to determine reaches a predetermined number O _END (S24), if not reached (No in S24), the 1 input order O _N It adds and returns to the number reading part 42 (S25). When the above-described processing of S21 to S25 is repeated and all the numbers match (Yes in S24), the unlocking instruction unit 44 determines that unlocking is possible and sends an unlocking command to the locking mechanism 6 (S26). ). The subsequent processing is the same as S9 to S19 of the unlocking process step with the biometric lock 7.

On the other hand, if the numeric data does not match as a result of the collation in S22 (No in S23), a buzzer sound or a voice message is output until the set number of trials (for example, 3 times) is reached, and the number is given to the unlocker Is prompted again (S27, S28). When the number of trials has been reached with some or all of the numeric data not matching (n = n _max : No in S27), a message to end the process is output, and the number of trials is erased from the memory and the unlocking process is performed. finish.

  In addition, this invention is not limited to above-described embodiment, A various deformation | transformation and change are possible.

  For example, in the above embodiment, a vault room of a financial institution has been illustrated, but the present invention can be similarly applied to a vault room other than a financial institution or a movable safe.

  In addition, the present invention is not limited to the type or specific configuration of the unlocking mechanism, and can be unlocked by monitoring the unlocking by the second unlocking mechanism after allowing the plurality of unlocking mechanisms to be unlocked independently. It has a feature in that a history is stored. Therefore, the types and specific configurations of the first and second unlocking mechanisms are not limited to the above examples, and any conventionally known or future proposed unlocking mechanism can be employed.

  Further, when the second unlocking mechanism is normally disabled and only enabled when the first unlocking mechanism is unusable, inside or outside the locking management system, Control means for enabling the second unlocking mechanism may be provided. This control means preferably uses a simple method such as authentication with a several-digit password or registration / cancellation of a flag so that the second unlocking mechanism can be immediately activated in an emergency.
