Description

  The present invention relates to an unlocking authentication system for an electronic lock by tally verification, in which each tally part of an electronic tally divided into tally matches each other, and the unlocking control of the electronic lock can be performed based on the tally verification result. It is about.

  Conventionally, in order to perform locking and unlocking operations on a normal lock mechanism, it is common to use an open / close key corresponding to the lock mechanism. In this case, in order to avoid the opening / closing operation of the lock mechanism based on the loss or theft of the open / close key and so-called picking, etc., there are various types of the lock mechanism and / or the open / close key and thus the lock device in a broad sense. However, as long as the lock device is a combination of a lock mechanism and an open / close key, no appropriate effective protection means have been proposed yet.

  In view of this point, as one conventional protective measure, after discarding the open / close key corresponding to the lock mechanism, various code lock devices that use the password instead of the open / close key as a reference or basis for the open / close operation, For example, an electronic lock unlocking means of a so-called numeric keypad + function key, or an electronic lock means that can be actuated by input of a secret code, which is also a lock-like mechanism in a broad sense (for example, a locking device such as an entrance door, For example, a power switch / lock device for various devices, a lock device such as a coin locker, and an ATM device for unattended banking operations are used.

  Thus, in the case of an electronic lock means that selectively uses the personal identification code as an external input, the most important point is that the personal identification code, which is the user's own personal authentication code, is effective. And it is a matter of practical privacy protection, that is, security. For this reason, various protective measures have been taken in the past, but in this case as well, both parties remember and retain the contents of the password, so that the encryption by the third party is possible. It was difficult to completely prevent plagiarism and deciphering.

  Also, on the other hand, for this reason, it seems that there is a consciousness that the security of the integrity of security is not only felt by the secret code that both parties can know, and that it does not possess an open / close key accordingly. There was a drawback that psychological factors such as anxiety and anxiety also acted.

  Therefore, in recent years, as a form of electronic lock opening and closing system, this kind of tally verification method, that is, a security ensuring technology using a tally verification method that applies a secret sharing method of a secret tally symbol has been realized. I was supposed to.

  The electronic lock opening / closing control technology using this tally collation method divides the tally symbol into two parts and stores one divided tally part and the other tally part separately to lock and unlock the electronic lock. In each opening / closing control operation of the lock, in particular, in the unlocking operation, a predetermined tally symbol is restored and used by matching each tally part of these both (tally collation).

  However, even with this tally verification method, it is not always possible to detect each tally part itself, and thus each tally encryption (so-called secret search), so it is effective to ensure its safety and reliability sufficiently. There was a fatal problem that it was not possible to achieve proper maintenance.

  The present invention has been made to solve the above-described problems of the conventional tally collation method, and the object of the present invention is to facilitate effective and confidential maintenance of each divided tally part. Thus, it is an object to provide an unlocking authentication system for electronic locks by tally verification, which substantially improves the security and certainty of tally verification.

  In order to achieve the above object, the present inventor has continued diligent development efforts, and as a result, selects a tally symbol string formed by arbitrarily combining a plurality of symbols, and selects the tally symbol string as a main tally part and a deposit tally part. And the function tally part are divided and encrypted, and the tally part of the subject and the function in the divided part is directly made available to the user, and the remaining deposit tally part is made as much as possible. By depositing it in the external management section in a concealed form and allowing it to be used indirectly by the user, it is possible to achieve effective concealment of the tally collation configuration, and the electronic by the tally collation It has been newly found that the combination of a lock and its key equivalent member can be effectively applied to users and departments that require various similar combinations of lock opening and closing. Of electronic lock by tally verification It invented the authentication system, and has been led to completion.

Become.

  In particular, since the existence of the external management unit is a separate aspect separated from the management main unit, it becomes even more difficult for the third party to detect the deposit tally that is deposited and registered in the external management unit. Become. In addition, when the deposit tally part is registered while being kept secret, the password detection becomes completely impossible.

  In this case, after providing a plurality of electronic locks, a plurality of key equivalent members corresponding to the respective electronic locks are provided for each electronic lock, and each key equivalent member is provided for each electronic lock. The function tally part common to each or a different function tally part is arranged for each electronic lock, so that the use of the function tally part itself is effectively secured and each electronic lock and each key equivalent member Diversity of use is realized, and each of these can be easily managed and managed by the management main body.

  Further, in this case, since a plurality of external management units are provided and each external management unit is configured with a different deposit tally portion for each external management unit, it is effective to use the deposit tally portion itself. Therefore, it is possible to obtain substantially the same action as the previous item.

Since the means is provided, even if an emergency occurs in the management main body part and the external management part and the power is cut off, the operation power supply to each electric device is always secured.

  Hereinafter, another embodiment of the unlocking authentication system for electronic locks by tally verification according to the present invention will be described in detail with reference to FIGS. 1 to 7.

  In each of the embodiments, “a combination of an electronic lock applied to each doorway of a house and a key equivalent member using tally verification” as an application target example will be described. However, for example, only this application house is not limited to the entrance door, but there is a doorway door, if necessary, each living room door, other doors, etc. There are multiple modes such as the entrance door, the emergency door, and the entrance door of each office of the company organization etc. that occupies it, and it is quite natural that it can be applied to these as well. .

  Further, the form of the electronic lock itself may be a lock device or the like that has a lock locking mechanism or is incorporated, and also a form of a key equivalent member that locks and unlocks the electronic lock. For example, an open / close key formed so as to have a cross-sectional shape that can be inserted into a keyhole of an electronic lock, and a function tally part can be changed and stored in a required part, a so-called tablet key, etc. For example, a card key or the like in which a function tally part readable by a predetermined reading device is similarly stored and mounted may be used. In each of the embodiments described below, for convenience of explanation, as the electronic lock, a lock device (hereinafter simply referred to as “electronic lock”) having the lock lock mechanism on the application target door is applied. As the key equivalent member, a tablet key (hereinafter, also simply referred to as “open / close key”) in which a function tally part is stored in the required part is used.

  As for those who use the key-equivalent member legitimately, as long as the application target is a general house, at least the whole family except for infants, etc., and the key-equivalent member common to all the family members It is the most universal to use (same open / close key) individually. However, after preparing a plurality of key equivalent members (open / close keys) that can be used as one characteristic of the present invention, a different function tally portion is individually mounted on each of the key equivalent members themselves. It is also possible to use this, and this is the same for each member who is allowed to possess a key such as a company occupying the building building.

[Prototype aspect of electronic tally structure used in each embodiment]
FIGS. 1 (a) to 1 (e) schematically show the original form of the electronic tally configuration used in each embodiment, and FIG. 1 (a) shows the overall tally configuration. FIG. 1B is an explanatory diagram showing a division mode of a tally structure, and FIG. 1C is an explanatory diagram showing a combination structure of twelve digits / three divisions that become a tally, FIG. 1 (d) is an explanatory diagram showing the mode of each divided tally part constituting the tally, and FIG. 1 (e) shows that the combination of encryption of each tally part is restored (in the tally collation result) It is explanatory drawing which shows the aspect in the state which the tally restoration | restoration was established.

  The tally structure of the electronic tally means used in each embodiment may be created as a code symbol string by arbitrarily selecting a series of tally symbol strings. As an example of its original form, each code such as “A, B, C,..., X, Y, Z” made of English capital, or “1, 2, 3,. And each number such as “numbers not limited to a single digit”, and combinations of these numbers, such as unordered combinations, etc. In a normal case, as a simplified form example, here, for example, a symbol configuration of “total 12 digits” is set. That is, since each of these symbols is a secret code, when this is expressed by a “*” mark, the tally structure is << ******* as shown in FIG. * >> is the original form 11.

For this reason, in each of the embodiments, the tally structure of the original form 11 is divided into three parts (equally divided into three sections) and used individually, so as shown in FIG. The tally structure is encrypted as each division mode 12 _{A to} 12 _{C of} << **** >>, and overall, as shown in FIG. 1 (c), 12 digits and 3 sections << *** ***, ***, ***, *** >> is the password combination configuration 13.

Here, when a simplified example of each of the individual division modes 12 _{A to} 12 _C is concretely illustrated, for example, as shown in FIG. 1D, the first division portion 14 _A = << 123 >> = << A123 >> (hereinafter referred to as “deposited tally part A”), second divided part 14 _B = << 456 >> = << B456 >> (hereinafter referred to as “main tally part B”), and third divided part 14 _C = << 789 >> = << C789 >> (hereinafter referred to as “function tally portion C”).

That is, when the above tally structure is arranged according to each embodiment, in this case, the electronic tally symbol string is
(1) A main part configuration as an intermediate band portion (an arbitrary changeable tally portion B serving as one reference for tally collation management B = a password portion consisting of 4 digits, for example, the configuration of << B456 >>);
(2) First sub-part structure that is attached to the front side band and restores the tally symbol string (an arbitrary changeable tally part A = 4 digit code part that is the other reference of tally verification management) For example, the configuration of << A123 >>
(3) Similarly, a second sub-part structure that is attached to the rear side band and restores the tally symbol string (consisting of an arbitrarily changeable tally part C = 4 digits that is the other reference of tally collation management) A password part, for example, the construction of the above << C789 >>
In the aspect before the tally verification, the divided tally parts A, B, and C are individually and independently provided in different states.

Therefore, when the above results, the overall combination of tally password is collated restored used in the present embodiments, each tally portions A, B, although the respective combinations = 3 ³ ways and C, these Of each combination of passwords, for convenience of explanation in each of the embodiments, typically: A123 (deposited in the external management unit and stored and stored as changeable) + B456 (stored and stored as changeable in the management main unit) + C789 (open / close It is assumed that the most simplified personal identification combination mode 15 for permitting the unlocking of the electronic lock is used. Here, since there is a case where the configuration of the tally part << A123 >>, which is the other standard of tally verification management, is deposited in the external management unit and is deposited and registered in a concealed manner in this case, It is assumed that a required deposit contract number (deposit number 71 to be described later) is assigned in advance for calling or changing the tally portion << A123 >>.

That is, in the case of each embodiment, finally, when the encryption combination of each tally part divided into three is established for restoration (tally restoration establishment in the tally verification result), it is shown in FIG. as,
○ << A123B456C789 >> = << 123456789 >>
Therefore, when the tally collation is performed, for example, the group rank within each of the tally groups of the tally parts A, B, and C is determined. Even if the combination is different, or the security code itself in each group or any one of the combinations is different, the required electronic lock cannot be unlocked at all. By the way, when variously comparing the code symbols in the tally parts A, B, and C as the code groups and various modes of the combinations, the number of code combinations reaches almost infinite. It is easy to see.

[Target of application of electronic tally means in each embodiment]
As described above, the electronic tally means in each of the embodiments, in other words, “a combination of an electronic lock and a key equivalent member (open / close key) by tally verification”, as described above, is basically and usual. However, there are various different application examples and modifications in view of the characteristics of the present invention, and these will be apparent from the following description.

The flowchart showing the unlocking operation procedure, FIG. 5B partially shows the related unlocking operation procedure in the case of a modification in which the key insertion recording / notifying device is added to the management main part of this system configuration. It is a flowchart.

<Locking operation of the electronic lock 31 in the first embodiment>
Regarding the locking of the door 30 with the electronic lock 31 in the case of the first embodiment, “automatic locking operation (automatically locking when the door is closed)” or “opening / closing key (key equivalent) is the same as in the past. Member) 51, and a normal locking operation (in this case, as a matter of course, the unlocking operation by tally verification must be requested in the unlocking operation, and the unlocking permission must be obtained). With the locking, the electronic lock 31 is locked by the lock lock mechanism 32 and is kept in an unlocked state. If necessary, a “locking operation using the open / close key 51 after obtaining permission by tally verification (similar permission by tally verification is also necessary when unlocking)” may be added. .

<Basic unlocking operation of the electronic lock 31 according to the first embodiment (see FIG. 5A); However, the case where the lock operation recording / notifying device 25 is not used in the management main body 21>
In the case of the first embodiment, an appropriate opening / closing key (key equivalent member) 51 is inserted into the key hole of the electronic lock 31 in the locked state (locked state) with the intention of the unlocking operation. As a result of the tally verification, the tally combination obtained on the basis of the open / close key 51 and the password combination mode 15 set in advance are confirmed by the operation procedure based on the following tally verification. The electronic lock 31 can be unlocked by the opening / closing key 51. On the other hand, when an improper opening / closing key 51 ′ is inserted, the tally combination obtained based on the opening / closing key 51 as a result of the tally verification matches the password combination mode 15 set in advance. Since they do not match, the opening / closing key 51 ′ cannot unlock the electronic lock 31 and can refuse the unlocking operation.

  That is, in the case of the unlocking operation according to the first embodiment, first, in accordance with the insertion (step S100) of the opening / closing key (key equivalent member) 51 or 51 ′, the opening / closing key 51 or 51 ′ The data of the function tally part C mounted in the function tally part fixed storage circuit 53 is only transferred from the key equivalent member transmitting device 54 to the function tally part receiving device 33 in accordance with the power reception through the power supply means 35 of the electronic lock 31. Limited and automatic non-contact transmission (S101).

  The transmitted function tally part C data is automatically contactlessly received (S102) by the function tally part receiving device 33 of the electronic lock 31 so that the electronic tally 31 automatically receives the function tally part C. In addition to the detection, the electronic lock connection / control device 34 transmits a signal to the management main unit first communication device 26 of the management main unit 21 via the connection line 61 (S103).

  Next, in the management main body control device 22 of the management main body 21, the data of the function tally part C detected and input via the management main body first communication device 26 is temporarily stored in the tally verification device 24 (S104). In the above, the data of the deposit tally part A corresponding to the function tally part C is immediately obtained, and the management main body second communication device 27 sends the data to the external management unit 41 of the external management unit 41 via the communication line 62. Only the deposit number 71, which is a means for selecting the deposit tally portion A, is signaled (S105) to request the provision of data for the deposit tally portion A.

  For this reason, in the external management unit control device 43 of the external management unit 41, when the deposit number 71 from the external management unit communication device 44 is received (S106), each registration registered in the deposit tally partial storage device 42 is received. From the deposit tally portion, the data of the corresponding deposit tally portion A corresponding to the deposit number 71 is automatically read out and selected (S107, decryption is impossible because the registration is kept secret). Thus, the selected deposit tally part A is provided in a concealed manner by the external management unit communication device 44 through the communication line 62 to the management main unit second communication device 27 of the management main unit 21 in a concealed manner. S108).

  Again, in the management main body control device 22 of the management main body 21, when the data of the deposit tally part A is provided via the management main body second communication device 27, the main body held by the tally collation device 24. For the tally part B, the detected and inputted function tally part C and the donated and inputted deposit tally part A are tally matched as expected (S109).

  As a result of the tally collation (S109), if the tally combination of these tally parts A to C matches the password combination mode 15 of the electronic tally held in the password combination mode storage device 23, the electronic lock It is determined that the open / close key (key equivalent member) used for the unlocking operation 31 is the use of an appropriate open / close key (regular key equivalent member) 51, and thereby the tally verification is established (the verification results match). Is confirmed, the unlocking permission data (collation matching confirmation data) 81 is output from the management main body control device 22 as a signal (S110).

  On the other hand, if the password combination mode 15 does not match, the open / close key (key equivalent member) used for the unlocking operation of the electronic lock 31 is an inappropriate open / close key (for example, an unauthorized key). If the tally verification is not established (the verification result is inconsistent), the management main body control device 22 receives the unlocking data ( The verification mismatch confirmation data) 82 is output as a signal (S111).

  Thus, when either the unlocking permission data 81 or the unlocking rejection data 82 as a result of the tally verification is output, for example, when the output signal is the unlocking permission data 81 In the case of proper use of the open / close key 51, the unlocking permission data 81 is transferred from the management main unit first communication device 26 via the connection line 61 to the electronic lock connection / control device 33 of the electronic lock 31. The signal is transmitted (S112).

  For this reason, the lock of the lock lock mechanism 32 that has restrained the electronic lock 31 so that it cannot be unlocked is released, and the unlockability display device 36 can be unlocked (unlocking permission). The blue light is turned on (S113) and / or a voice notification to that effect is made. Thereafter, the unlocking operation (S114) of the electronic lock 31 by the open / close key 51 is performed, and the process ends.

  Accordingly, the signal output of the unlocking permission data 81, which is the determination result that the proper opening / closing key (regular key equivalent member) 51 has been used by the tally verification (S109) in this way (S110). Thus, the unlocking operation of the electronic lock 31 by the opening / closing key 51 can be easily performed. In other words, in other words, the maintenance procedure for unlocking the open / close key 51 can be effectively achieved.

  On the other hand, when the output signal is unlocking data 82 (in the case of improper use of the open / close key 51 '), the unlocking rejection data 82 is similarly stored in the electronic lock. 31 is transmitted to the electronic lock communication device 33 (S115).

  However, in this case, since the opening / closing key 51 ′ used for the unlocking operation is inappropriate, the lock of the electronic lock 31 cannot be released, and the opening / closing key used also in the unlocking permission / inhibition display device 36. By displaying a red light blinking (S116) and / or voice notification to that effect that 51 'is improper and cannot be unlocked (unlocking refusal), for example, proper When an exchange of an appropriate opening / closing key 51 is urged within the predetermined time (S117), an exchange with the opening / closing key 51 from the step S100 is promoted. The lock check is repeated unless it is repeatedly executed and the exchange of the proper open / close key 51 is made within the predetermined time.

  Therefore, the signal output of the unlocking rejection data 82 (S111), which is the determination result that the improper opening / closing key (unauthorized key equivalent member) 51 'has been used by the tally verification (S109) in this way. ), The unlocking operation of the electronic lock 31 by the opening / closing key 51 ′ is surely rejected (see the next section for one response after rejection). In other words, in this case, in other words, a maintenance procedure (security ensuring) for unlocking the opening / closing key 51 can be effectively achieved.

<Unlocking operation in the case of a modification in which the lock operation recording / notifying device 25 is used in combination with the management main body 21 in the first embodiment (see FIG. 5B)>
In the unlocking operation of the electronic lock 31 in the first embodiment, the following operation procedure is added when causing the management main body 21 to use the lock operation recording / notification device 25 together.

  That is, in the modification of the first embodiment, following the temporary storage (S104) of the detected function tally part C, the opening / closing key (key equivalent member) 51 or 51 ′ is inserted into the electronic lock 31 (S100). ) (The output of the lock operation data 83) is sequentially recorded and saved over time in the lock operation recording / notification device 25 (S200) and the result of the tally verification (S109). The signal output (S111, unlockable output) of the unlocking rejection data 82 is also recorded and stored in the lock operation recording / notifying device 25 in the same manner as the unauthorized key use fact data 84 (S200). Will be.

  Therefore, by extracting the key operation status confirmation data 85 from the stored record of the lock operation record / notification device 25, it is possible to easily examine and confirm the key operation status based on the key operation status confirmation data 85, respectively. become.

  On the other hand, when the unlocking data 82 and consequently the illegal key use fact data 84 are input to the lock operation recording / notifying device 25, the unauthorized opening / closing key 51 'is used. For example, an alarm message can be automatically taken out immediately after a certain period of time has elapsed (after the time required for the exchange of the proper opening / closing key 51 in the key exchange step 117), for example, by alarming. Will be appropriately sent or reported to the outside.

  Accordingly, by using the key insertion recording / notification device 25 in combination with the management main body 21 in this way, it is effective to grasp the actual state of the door opening / closing due to the user's access status and other reasons from the stored contents of the record. In addition to this, it is possible to easily check for illegal use by inserting an unauthorized opening / closing key 51 ', and to make notifications and notifications to the outside as necessary.

<< Second Embodiment >>
FIG. 6 is an explanatory diagram showing a main configuration of an electronic lock unlocking authentication system based on tally verification to which the second embodiment is applied.

  In the second embodiment, in the configuration of the first embodiment, a specific restriction clause is added with respect to the unlocking operation using the target opening / closing key (key equivalent member) 51, thereby detecting the password of the functional password portion C. It is intended to make the prevention more effective.

  That is, when a plurality of opening / closing keys 51 are provided for each electronic lock 31 and each opening / closing key 51 is stored with a function tally portion C different for each electronic lock 31, When the function tally part C for each open / close key 51 corresponding to the lock 31 is originally absent in accordance with the daily action time of the corresponding user (the person who has the appropriate open / close key 51), etc. Only during the time that can be considered, the unlocking operation of the electronic lock 31 using the open / close key 51 is automatically disabled (invalidated).

  That is, in the second embodiment, at least one of the management main body 21 that is also the management center of the system or the external management section 41 that has a deposit contract with the management main body 21, in this case, As shown in FIG. 6, a time setting device 91 for outputting the function tally part prohibition data 92 for each target opening / closing key 51 is provided by attaching a timing device 91 a to the management main body 21. With respect to the specific target open / close key 51 (target open / close key possessed by the corresponding user), the function tally partial use prohibition data 92 within the specific time range 93 determined for each corresponding user as a required applicable restriction condition. As a result, the tally collation in the tally collating device 24 is disabled (invalidated), that is, the unlocking data 82 is output and the target opening / closing key 51 is output. According is obtained so as to invalidate the unlocking of the electronic lock 31.

  Thus, as the specific time range 93 determined for each corresponding user, for example, if the user is a general office worker, etc., after leaving the home to engage in normal work on each target day Between 7:00 am and 7:00 pm, which is the appropriate time until returning home, that is, the time corresponding to working hours including the time required for attendance / exit of the corresponding user, and the time when he / she is absent from home In the specific time range 93, the tally collation of only the functional tally part C among the tally parts A, B, C in the tally collation device 24 is performed. What is necessary is just to make it invalidate.

  Therefore, in the case of the second embodiment, when the unlocking operation using the target opening / closing key 51 (originally the target opening / closing key of the bag possessed by the user) 51 of the electronic lock 31 is performed. When the function tally portion C from the target opening / closing key 51 is automatically detected by making the time within the specific time range 93 (time measurement by the time measuring device 91a), as is apparent from FIG. From the setting device 91, instead of the data signal of the function tally part C, the function tally part use prohibition data 92 is output as a signal to the tally collation apparatus 24, thereby invalidating the tally collation itself. It can be made.

  Here, in the second embodiment, the case where the time setting device 91 that accompanies the time measuring device 91a is provided on the management main body 21 side has been described.
