Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a lock device that can be retrofitted to a conventional cylinder lock portion that is locked and unlocked by a portable terminal having a key function, and in particular, after a first unlock by collation of an ID code via the portable terminal. The present invention also relates to a lock control device for unlocking a lock by a second unlocking operation in which a cylinder is rotated manually by simple key insertion.
[0002]
[Prior art]
In general mechanical security systems, various sensors that detect abnormal situations such as intruders and fires and a reporting device that reports when abnormalities are detected are installed in the contracted building or dwelling, and unmanned at night or on holidays. The security of the building or the house where the resident went out and was absent. When the sensor detects an abnormal situation, a notification device notifies the monitoring center of the security company that the abnormal situation has been detected via a telephone line or the like. Upon receiving the report, the security company's monitoring center dispatches a security guard to the building or the residence to check the situation and, if necessary, requests a dispatch to the police or fire department or other related organizations. A security guard dispatched to the site uses a key previously borrowed from a contractor to enter a building or a house and investigate the cause of the abnormality detected by the sensor. In addition, depending on the condition of the abnormalities that have been confirmed, correct the situation or take necessary measures to prevent the damage from spreading.
[0003]
By the way, in such a security environment, there are the following backgrounds and improvement points regarding keys for entering a contracted building or house.
[0004]
First, the borrowed key is stored in a dedicated key box, and the key box is stored in a security guard's waiting area or put on a security vehicle of a security officer in charge of the area, but the number of keys increases. It becomes more difficult to secure a storage space as time elapses. For example, one security guard holds around 200 keys and guards the area (building) in charge.
[0005]
Second, each security officer is assigned an area to be guarded, and when an abnormal situation is detected, a security officer in charge of the area is dispatched to the site of the occurrence. However, if the security officer in charge of the area is in charge of another matter and cannot go to the above site, a security officer in charge of the adjacent area must be dispatched instead. At this time, the security officer in charge of the adjacent area did not have the key of the contractor in the area, so it was necessary to join the security officer in charge of the area at any place and hand over the key .
[0006]
Also, if the contractor's key is stored in the security guard's waiting area, the security guard in charge of the district is dispatched, or the security guard in charge of the adjacent district is dispatched instead. Had to stop by the waiting area in the area before heading to the site. In this way, it takes too much time to get the key to the place where the abnormal situation occurs despite the emergency, in other words, it takes too much time to go to the site to transfer the key Become. As described above, complicated procedures such as key transfer have been required.
[0007]
Further, the above situation will be described with reference to FIG. As shown in the figure, the districts in charge of the guards a to d are assigned as the districts A to D, respectively, and each guard is waiting at a standby location in each district.
[0008]
The keys to enter the contracted buildings in each district are kept by security guards in each district. For example, when an abnormal situation is detected in the contracted building A1 in the district A, the guard a is dispatched to the contracted building A1 in accordance with an instruction from the monitoring center, and the guard a performs a response such as a situation check.
[0009]
At this time, if an abnormal situation is detected at the contractor A2 in the district A, the security guard a should be dispatched to the contractor A2, but cannot respond because it is dispatched to the contractor A1. . Then, the guard c in the adjacent district C is dispatched to the contractor A2. However, since the guard c does not have the key of the contractor in the district A, he joins the guard a and waits for the contracted building. Since the vehicle heads to A2 or stops at the waiting place A before heading to the contracted party A2, the detour is largely made in comparison with the case of directly heading to the contracted building A2. Therefore, it took extra time to arrive at the site.
[0010]
Third, when an abnormal situation is detected at the contractor and the guard enters the building to check the situation, maintenance is performed so that the guard's equipment such as sensors installed at the contractor can function properly. The key borrowed from the contractor is also used when a worker enters the contractor's building for inspection work or replacement work. Even in such a case, it is necessary to exchange keys between the security staff in charge of the area and the maintenance staff, which wastes time and is troublesome.
[0011]
Fourth, the key is duplicated in advance so that it is not necessary to exchange the key in the second and third backgrounds / improvements, and the security officer in charge of the district and the neighboring district are in charge of it. It may be possible to hand over to security guards, but on the other hand the number of keys stored by each security guard will increase significantly. There is a problem that the risk of theft or loss increases as the number of keys increases, and many contractors are required to implement this because they are resistant to copying keys Is difficult.
[0012]
Fifth, in a building with a large number of rooms, such as a hotel, a master key system is adopted in consideration of not having to carry many keys. In this master key system, a plurality of locks are unlocked and unlocked using a master key. Applying this scheme can reduce the number of keys that security guards must keep. However, in the conventional master key method, if the master key is lost or stolen, there is a possibility that the master key is misused by others. Should such a situation occur, all locks corresponding to the master key would need to be replaced, which would require a great deal of cost and labor. For this reason, the conventional master key method cannot be easily introduced as a key for security guards to enter the buildings of a plurality of contractors.
[0013]
Sixth, in order to reduce the number of keys stored by security guards, it is conceivable to replace locks used at entrances and exits of contracted buildings with electric locks so that they can be unlocked and unlocked with a password. However, because the electric lock itself is expensive, and when installing the electric lock later, it is necessary to perform wiring work to secure the power supply, and the electric lock is easily installed because the construction cost increases. I couldn't.
[0014]
Therefore, as a solution to the above-mentioned points to be improved, a portable terminal having a master key function and an electric lock used for the portable terminal have been proposed by the present applicant (for example, see Patent Document 1). In particular, the structure of a retrofit electric lock is shown here. This post-installed electric lock is an electric lock that is provided inside a door, connects a motor and a rotating shaft of the lock via a link mechanism, and rotates the rotating shaft by a driving force of the motor.
[0015]
Further, in a cylinder lock which is unlocked by rotation of an inner cylinder of a cylinder including an outer cylinder and an inner cylinder housed in the outer cylinder and having a key insertion hole, the outer cylinder and the inner cylinder are mechanically engaged with each other. A movable pin provided at a position not protruding from the key insertion hole, an electromagnetic actuator for moving the pin, a key code transmitted from an electronic key inserted into the key insertion hole of the inner cylinder and a key code stored in advance. And an electronic circuit for operating the electromagnetic actuator so as to move the engaging pin and release the mechanical engagement when they match, and a cylinder lock having a built-in outer cylinder. (For example, see Patent Document 2).
[0016]
Since the key code is registered in the electronic key of the cylinder lock, similarly to the conventional physical key, the number of locks increases when there are many locks. There is a case where the complication at the time of delivery is not eliminated, and further, it is abused at the time of loss or theft. In other words, since the key code is fixedly registered in each electronic lock, an appropriate action (rewriting, erasing, etc.) cannot be performed at the monitoring center when the electronic lock is lost or stolen, and the above-mentioned improvements in management and security are made. It did not eliminate the point.

[Problems to be solved by the invention]
However, the conventional retrofitted electric lock as described above remodels (additionally processes) a conventional cylinder lock and installs it on a door. In the case of external attachment, the external appearance (design) is not impaired. When there is a restriction or when the inside of the door is provided, it is necessary to store the entire apparatus in a small space in order to install the apparatus in a limited space. However, due to the structure in which the lock shaft is rotated by the driving force of the motor, the motor that generates a predetermined torque or more and the link mechanism that transmits the driving force of the motor are housed in a small space, or are small in size due to restrictions on appearance. It is necessary to minimize the electric power supplied to the electric lock, because it requires no special wiring work because it is retrofitted.

[0030]
(Work flow)
The mobile terminal according to the present invention is used mainly in the following two cases. At a contractor who has introduced a mechanical security system, when the contractor is absent, such as at night or on a holiday, and is set to a security state, an abnormal situation is detected by a sensor and a notification is sent to the monitoring center. This is the first case where a security guard is dispatched for confirmation or the like. In addition, a contractor who has introduced a mechanical security system performs maintenance work for checking or replacing security devices such as sensors periodically or upon request at night or on holidays when the contractor is absent. Is the case.
[0031]
In the case of maintenance work performed by the contractor in the presence of a person, or when a manager is resident in the building, when the key is already unlocked and the key is unnecessary, or when the necessary key is If you can borrow, you do not need to use a mobile terminal.
[0032]
Hereinafter, the outline in each case will be described.
[0033]
(1) Response by detecting abnormal situations
With reference to FIG. 1, a description will be given of a response by detecting the abnormal situation. In the figure, a contracted building A1 to be guarded has a sensor s and a reporting device T constituting a mechanical security device, a lock (lock mechanism) k provided at an entrance door, and an input means R for locking and unlocking the lock. Prepare. In addition, the guard a1 has the portable terminal 1 used in the present invention. As described later, the mobile terminal 1 is configured to send an unlock signal for unlocking the lock (lock mechanism) k to the input means R of the contract building A (see FIG. 9). .
[0034]
(A) Detection of abnormal situations
When the sensor s installed at the contractor detects an abnormal situation, the reporting device T notifies the monitoring center 100 that the abnormal situation has been detected.
(B) Dispatching instructions to security personnel
When the monitoring center 100 receives the notification, the monitoring center 100 issues a dispatch instruction to the security guard a1 to go to the site using a wireless or mobile phone and check the situation. At this time, the key data is transmitted to the portable terminal 1 possessed by the guard a1.
(C) Status check by security guards
The security officer a1 is dispatched according to the instruction from the monitoring center, and upon arriving at the site, uses the key data sent from the monitoring center 100 and uses the portable terminal 1 to lock the lock (lock) provided at the entrance of the contracted building. (Mechanism) Unlock k and enter to confirm the cause of the abnormal situation detected by the sensor s. In addition, according to the identified cause of the abnormal situation, necessary measures such as collecting the situation and preventing the spread of the damage are performed. When the response is completed, the guard a1 locks the lock (lock mechanism) k with the portable terminal 1 and exits.
[0035]
(2) Maintenance work
Next, the maintenance work by the maintenance staff b1 will be described with reference to FIG.
(D) When an inspection / replacement is requested due to a failure of a security device such as the sensor s or the notification device T installed in the contracted building A1, the maintenance staff b1 changes the contracted building due to a periodic inspection of the security device. When heading to A1, the maintenance staff b1 informs the monitoring center 100 that he or she will be performing work, tells him to enter the contracted building, and makes a key data transmission request.
(E) Upon receiving notification of entry to the contracted building A1 and a request for key data, the monitoring center 100 transmits the key data to the portable terminal 1 of the maintenance staff b1.
(F) Maintenance work by maintenance personnel
When the maintenance person b1 arrives at the site, he uses the key data received from the monitoring center 100 to unlock the key k provided at the entrance of the contracted building A1 with the mobile terminal 1 and enters the building, and enters the sensor. Perform maintenance work such as repair and inspection of security equipment. When the maintenance work is completed, the maintenance staff b1 locks the key k with the portable terminal 1 and exits.
[0036]
(3) When receiving only necessary key data locally
Next, referring to FIG. 3, as another procedure, a case where the guard a1 or the maintenance staff b1 is dispatched to the contracted building A1 and requests only the necessary key data from the monitoring center 100 at the site and has the same transmitted. Will be described.
[0037]
(G) Dispatching security and maintenance personnel
When the sensor s installed in the contracted building A1 detects an abnormal situation and is requested to dispatch or check security equipment, the guard a1 or the maintenance staff b1 heads to the site. At this point, no key data is transmitted.
(H) Acquisition of lock ID
When there is a key that needs to be locked and unlocked at the site, the guard a1 or the maintenance staff b1 transmits the ID of the lock of the portable terminal 1 from a key control device (not shown), or the identification assigned to the lock. The security officer a1 or the maintenance staff b1 confirms the number and inputs the number to the portable terminal 1 to acquire the ID of the lock to be unlocked.
(I) Lock data request, lock data transmission
The ID of the lock obtained in (h) is transmitted to the monitoring center 100, and a request is made for key data for unlocking and unlocking. The monitoring center 100 transmits the key data corresponding to the lock ID according to the request.
(J) Security and maintenance personnel
Using the key data received from the monitoring center 100, the guard a1 or the maintenance staff b1 unlocks the lock (lock mechanism) k provided in the contracted building A1 with the mobile terminal 1 and enters the building. After taking necessary measures and completing the work, the portable terminal 1 locks the lock (lock mechanism) k and exits.
[0038]
In the case where the key data is requested, if a monitor at the monitoring center 100 directly responds, the procedure for transmitting the key data may be a burden on the monitor. Therefore, an automatic response device (not shown) of the monitoring center 100 is installed, and when the security personnel a1 or the maintenance personnel b1 requests key data, identification information such as a lock ID is transmitted to the automatic response device of the monitoring center 100. Automatically selects key data to be transmitted to the mobile terminal 1 and transmits the key data.
[0039]
(4) Necessity of certification
In the above-described business flow, the key data is transmitted from the monitoring center 100 to the security staff a1 or the maintenance staff b1, and the locking and unlocking of the lock provided at the gateway of the contractor by the mobile terminal 1 is performed. Here, since the following misconduct is assumed, a confirmation act for preventing the misconduct is necessary.
[0040]
When transmitting the key data in the above (b), (e), and (i), when transmitting the key data, to which portable terminal the key data was transmitted, in order to prevent unauthorized acquisition and use of the key data. Need to know who was using the mobile device in the first place. In particular, in (e) and (i), since it is conceivable that a third party may request transmission of key data by falsely identifiable, the user is a legitimate mobile terminal or has a valid right to use the mobile terminal. It is important to make sure that you are the one given.
[0041]
When locking or unlocking the locks in (c), (f) and (j) above, in order to prevent unauthorized locking and unlocking, the user must be a legitimate mobile terminal or a person authorized to use the mobile terminal. You need to check if there is. There are two types of unauthorized locking and unlocking: the case where an unauthorized device with the same function as a mobile terminal is manufactured and locked and unlocked, and the case where a third party robbes a legitimate mobile terminal and uses it illegally. Therefore, confirmation to prevent these actions is important.
[0042]
Therefore, in view of the above-described background, in using the mobile terminal according to the present invention, it is assumed that authentication is incorporated as confirmation processing for preventing fraud.
[0043]
Note that this authentication is not an essential procedure, but may be performed by a procedure or communication method when the monitoring center 100 gives an instruction to the security guard a1 if the other party can be confirmed without performing authentication, or if the lock is locked. This is unnecessary if the effect of preventing unauthorized use cannot be obtained even if authentication is adopted depending on the type.
[0044]
(5) Configuration of mobile terminal
Next, a configuration example of the mobile terminal according to the present invention will be described with reference to FIG.
FIG. 4A is a first configuration example in which the functions of a mobile terminal and a mobile phone are integrated, and FIG. 4B is a second configuration example in which the mobile terminal is connected to a mobile phone for use. . FIG. 5 is an explanatory diagram showing an example of the external configuration of each of the portable terminal in FIG. 4A and the portable terminal in FIG. 4B.
[0045]
The mobile terminal 1a illustrated in FIG. 5A includes a display unit 11, an operation unit 12, an authentication unit 13, a control unit 14, a storage unit 15, a transmission / reception unit 16, an unlock signal output unit 17, and a tamper-resistant unit 18. .
[0046]
The mobile terminal 1b shown in FIG. 5 (b) is different from the mobile terminal 1a in that a portion provided with an input / output unit 19 in place of the transmission / reception unit 16 and other configurations and functions thereof are basically the same. The reference numerals are attached. Therefore, in the case of FIG. 5B, the input / output unit 19 and the mobile phone (such as a wireless device) 20 correspond to the transmitting / receiving unit 16 in FIG. 5A.
[0047]
The display unit 11 displays various information such as input confirmation when the operation unit 12 is operated and operation result confirmation. The operation unit 12 performs operations for the security staff a1 or the maintenance staff b1 to lock and unlock the lock (lock mechanism) k, and (if necessary) inputs a password for authentication.
[0048]
When the portable terminal 1a (1b) receives the key data or is used to lock and unlock the lock provided at the contractor, the authentication unit 13 uses the portable terminal 1a (1b). Authentication for confirming whether or not the user has been given the right to perform the authentication. At the time of authentication, an existing technique such as input of a personal identification number, fingerprint collation, or reading of an ID card owned by a user is appropriately used. In the case of fingerprint collation or reading an ID card, it is necessary to connect a fingerprint input device or a card reader to the portable terminal 1a (1b), or to provide the function to the portable terminal.
[0049]
The control unit 14 performs various controls of the mobile terminal 1a (1b). The storage unit 15 stores the key data received from the monitoring center 100. The transmission / reception unit 16 integrates wireless and mobile phone functions, uses it as a communication means with the monitoring center 100, and also receives key data. When communicating with the monitoring center 100, transmission and reception of authentication data are also performed here.
[0050]
The unlocking signal output unit 17 sends an unlocking signal for unlocking, and unlocks and unlocks input means such as a card reader provided for unlocking and unlocking a lock installed at the contractor. Send a signal to lock and unlock. The locking / unlocking signal is not limited to a signal used for directly locking / unlocking, but may be identification information used for locking / unlocking.
[0051]
When the tamper-resistant means 18 detects that the portable terminal 1a (1b) has been disassembled, it prevents the key data from being illegally robbed by the disassembly of the portable terminal 1a (1b). Force erase. That is, tamper resistance (tamper resistance) is ensured so that key data is never leaked to a third party. If there is information other than the key data that the user does not want to be illegally obtained, it may be deleted at the same time.
[0052]
The input / output unit 19 is connected to another wireless device 20 such as a mobile phone 20a and a wireless device 20b, and exchanges signals.
[0053]
When a higher level of security is required, when performing authentication to confirm that the mobile terminal is genuine, authentication and output of the unlocking signal are performed as a series, and Locking and unlocking is performed after being recognized as a terminal.
[0054]
The transmission / reception unit 16 (input / output unit) and the locking / unlocking signal output unit 17 may be shared. In addition, the portable terminal 1a (1b) includes a battery (not shown) for supplying power. When using a retrofitted electric lock, a power supply for driving the electric lock device may be supplied.
[0055]
The mobile terminal 1a (1b) according to the present invention receives key data from the monitoring center 100 by communicating with the monitoring center 100. At this time, it is realized by using any of the communication means described below.
[0056]
(6) Connection with wireless device
When an instruction from the monitoring center 100 or a report from the security officer is performed between the monitoring center 100 and the security staff a1 or the maintenance staff b1, if the radio is used, the wireless device 20a and the portable terminal 1b are connected. Connection may be made using a connection cable or the like, and key data may be received.
[0057]
(7) Connection with mobile phones and PHS
When an instruction from the monitoring center 100 or a report from the security officer is performed between the monitoring center 100 and the security staff a1 or the maintenance staff b1, if the mobile phone or the PHS 20a is used, the mobile phone or the PHS 20a is used. Connection may be made using a connection cable or the like, and key data may be received.
[0058]
(8) When a wireless device, mobile phone, or PHS function is provided in a mobile terminal
As shown in FIG. 4A, the mobile terminal 1a is provided with a communication function using a wireless device, a mobile phone, a PHS, and the like, and is used for instructions from the monitoring center 100 and reports from the security officer a1, Key data can be received.
[0059]
If a mobile phone or PHS function is provided, the mobile terminal can be specified by a telephone number when calling the mobile terminal from the monitoring center 100, and the caller ID is used when calling the monitoring center 100 from the mobile terminal. To identify the mobile terminal. Therefore, in this case, when transmitting the key data from the monitoring center 100, the authentication for confirming whether or not the terminal is a legitimate mobile terminal can be omitted.
[0060]
Note that the mobile phone may be either an analog type or a digital type, but a digital type (for example, TDMA: Time Division Multiple Access, or a next generation) capable of relatively stable communication in a wireless section and capable of high-speed communication. A mobile communication system such as IMT-2000) is preferable. That is, as a mobile phone system, an IMT-2000 such as a PDC (Personal Digital Cellular) system, a cdmaOne (Code Division Multiple Access), or a third generation type system (for example, wideband-CDMA, cdma2000, etc.). It is possible to adopt a method. Also, a PHS (Personal Handy-phone System) may be used if the movement is not a high-speed movement but a relatively narrow range. In the case of the PHS system, the internal configuration of the wireless communication network is a known PHS system. Communication means such as Bluetooth can be used for communication between the portable terminal and the electric lock.
[0061]
(9) Enter the encryption code into the mobile terminal
When an instruction is given from the monitoring center 100 to the guard a1 using a mobile phone or wireless communication, an encryption code (for example, a sequence of about 10 digits) is transmitted from the monitoring center 100 as key data, and the guard a1 sends the encryption code. The encrypted code is input to the mobile terminal, decrypted by the mobile terminal, and used as key data.
[0062]
When generating this encryption code, a different encryption code is generated depending on the date of using a parameter such as a date, and the encryption code obtained by encrypting key data for locking and unlocking a certain lock is not the same. It is preferable to do so.
[0063]
Also, in the authentication at the time of sending the key code, the same encryption / decryption algorithm is used to transmit the encrypted code obtained by encrypting the security officer a1 and the identification number of the mobile terminal to the monitoring center 100. You may make it decrypt and confirm. In this case, there is a merit that a wireless device used for communication between the monitoring center 100 and the guard a1 can be used as it is.
[0064]
(10) About authentication of person using mobile terminal
There is the following method as a method for confirming whether or not a person who uses a portable terminal is a person who has been given valid authority.
[0065]
(A) Authentication on mobile terminals
When the key data is received from the monitoring center 100, when the lock is unlocked and unlocked by the mobile terminal, the information to be compared previously stored (registered) in the mobile terminal and the ID card owned by the person using the mobile terminal are stored in the ID card. The stored information is compared and authentication is performed.
(B) Authentication at the monitoring center
When receiving key data from the monitoring center 100, information stored in the user's ID card and biometric information such as a user's fingerprint read by the mobile terminal are transmitted to the monitoring center 100. Authentication is performed by comparing the stored information with the information to be compared.
[0066]
When locking and unlocking with a mobile terminal, authentication may be performed in the monitoring center 100 as in the case of receiving key data, but communication with the monitoring center 100 is performed every time locking and unlocking increases communication costs. In addition, there is a possibility that a mobile phone or a PHS cannot be used in the building and authentication cannot be performed.
[0067]
Therefore, when locking and unlocking with a portable terminal, it is sufficient to confirm whether or not the user is the same as the authenticated user when receiving the key data. Therefore, the portable terminal stores the information of the user used for the authentication at the time of receiving the key data, and compares the stored information with the information of the user when locking and unlocking.
[0068]
(11) Authentication of mobile terminals
When receiving the key data from the monitoring center 100, the following methods are available as an authentication method for confirming that the portable terminal is a legitimate one.
[0069]
An identification code is assigned to the mobile terminal in advance. In the monitoring center 100, each identification code assigned to the mobile terminal is registered. When the mobile terminal communicates with the monitoring center 100 to receive the key data, the mobile terminal transmits its own identification code to the monitoring center 100, and the monitoring center 100 compares the transmitted identification code with the identification code registered in advance. Check to make sure it is a legitimate mobile device.
[0070]
At this time, it may be simultaneously authenticated that the user of the portable terminal is a person who has been given valid authority. Further, the monitoring center 100 prepares a database in which the correspondence between the responsible area, the security staff (maintenance personnel) and the mobile terminal is registered in advance, and the area where the contracted party is located, the user of the mobile terminal, and the mobile terminal. By confirming that the correspondence between the terminals is correct, more reliable authentication may be performed.
[0071]
When it is confirmed that the terminal is a legitimate mobile terminal, the monitoring center 100 transmits key data to the mobile terminal. The key data to be transmitted at this time is only the key data necessary for the contracted party going from now on. If a contractor needs a plurality of key data, a plurality of key data are transmitted. Note that depending on the communication method between the mobile terminal and the monitoring center 100, the confirmation that the mobile terminal is a legitimate one can be simplified.
[0072]
When a mobile terminal is provided with a mobile phone or PHS function like the mobile terminal 1a, when the mobile terminal is called from the monitoring center 100, a target mobile terminal can be designated by a telephone number, and the monitoring center 100 When called, the monitoring center 100 can specify the mobile terminal using the caller ID notification. Therefore, by using these, it is possible to confirm that the portable terminal is genuine, and it is not necessary to perform confirmation using an identification code or the like.
[0073]
(12) Authentication of mobile terminal and contracted lock (in the case of retrofitted electric lock)
When using a so-called “retrofit electric lock”, which is a control lock that can be electrically controlled to an existing mechanical lock such as a cylinder lock, the power is supplied from the outside and the unlocking signal is output. If locking and unlocking can be performed only by inputting, any battery can be connected, and anyone can lock and unlock by inputting a locking and unlocking signal from an arbitrary control device.
[0074]
Therefore, in order to prevent such a case, in the case of using a retrofitted electric lock, it is necessary to confirm the authenticity of the portable terminal by performing authentication between the electric lock and the portable terminal.
[0075]
FIG. 6 shows an example in which authentication is performed using a public key. A public key (1), a secret key (1), and key data (lock ID 123) issued from an arbitrary certificate authority A are registered in the electric lock control device 30 in advance. In the mobile terminal 1, a public key (2) and a private key (2) issued by the certificate authority A are arbitrarily registered in advance. Authentication is performed according to the following procedure.
[0076]
{Circle around (1)} When entering a building of a contractor due to detection of an abnormal situation or maintenance work, the authentication is performed between the monitoring center 100 and the mobile terminal 1 and then encrypted by the monitoring center 100 using the public key (2). The converted key data (lock ID 123) is transmitted to the mobile terminal 1 (S1).
(2) The public key (1) and the public key (2) registered in advance are exchanged between the control device 30 for the electric lock and the portable terminal 1, and it is mutually confirmed that the public keys (1) and (2) are recognized by any certificate authority A. (S2).
(3) A document in which the key data (lock ID 123) encrypted with the public key (2) received in (S2) is written is transmitted from the electric lock control device 30 to the portable terminal 1, and the signature is sent. Is requested (S3).
(4) The portable terminal 1 decrypts the document received in (S3) with its own secret key (2), and decrypts the key data transmitted from the monitoring center 100 in (S1) and the key data transmitted in (S3). The key data transmitted from the lock control device 30 is compared (S4).
(5) If the key data is equal, the portable terminal 1 performs a digital signature on the document decrypted in (S4) (S5).
{Circle around (6)} The document digitally signed in (S5) is encrypted with the public key (1) received in (S2) and transmitted from the portable terminal 1 to the control device 30 of the electric lock (S6).
{Circle around (7)} After confirming the signature, the control device 30 for the electric lock unlocks (S7).
[0077]
Therefore, unlike the example shown in FIG. 6, there is almost no risk of being abused by another person due to strict authentication, and high reliability that can be used in important facilities and the like can be obtained. However, when used in a general building, it becomes too strict and more burdensome on management.
[0078]
Therefore, the mobile terminal 1 used in the present invention cannot be used unless key data is transmitted from the monitoring center 100, and when the key data is transmitted from the monitoring center 100, the mobile terminal 1 is authentic, and It is sufficient to simplify a part of the authentication because the user of the mobile terminal 1 checks whether the user is authorized, and the mobile terminal 1 prevents the key data from being illegally obtained. Reliability can be obtained. FIG. 7 shows an example in which a part of the authentication in the example of FIG. 6 is simplified.
[0079]
A public key (1), a secret key (1), and key data (lock ID 123) issued from an arbitrary certificate authority A are registered in the electric lock control device 30 in advance.
[0080]
{Circle around (1)} When entering the contracted building due to abnormal situation detection or maintenance work, the authentication is performed between the monitoring center 100 and the mobile terminal, and then the monitoring center 100 encrypts the public key (1). The key data (lock ID 123) is transmitted to the mobile terminal 1 (S11).
(2) The portable terminal 1 transmits the encrypted key data (lock ID 123) received from the monitoring center 100 in (S11) and the locking / unlocking signal to the control device 30 of the electric lock (S12).
(3) The control device 30 for the electric lock decrypts the encrypted key data (lock ID 123) received in (S12) with the secret key (1) and compares the key data (lock ID 123) ( S13).
{Circle around (4)} After confirming that the key data matches, the lock is unlocked by the lock signal received in (S12) (S14).
[0081]
(13) Handling of key data stored in mobile terminals
The key data received from the monitoring center 100 is stored in the mobile terminal 1. However, even if the mobile terminal 1 is stolen or lost, the following countermeasures are taken to minimize the damage caused by the leakage of the key data. Is performed, and the minimum number of key data is stored in the mobile terminal 1 only when needed. The procedure is as follows.
[0082]
(1) When new key data is received from the monitoring center 100, the key data received in the past is deleted.
{Circle around (2)} Erasing is performed by operating an erasing means provided in the portable terminal 1. In this case, it is sufficient to delete the security guard a1 after the security officer a1 exits the contracted building A1 (locks the entrance door) after the abnormality check and the collection of the situation are completed.
{Circle around (3)} After receiving the key data from the monitoring center 100, the key data is made valid for a certain period of time and deleted.
Information for specifying the validity period is included in the key data.
{Circle around (4)} A tamper switch is provided in the portable terminal 1, and key data is erased when an action such as disassembly is performed.
(5) If unlocking is performed once, key data is deleted or unlocking operation is prohibited.
{Circle around (6)} The key data is valid from when unlocking is performed until a locking operation is performed.
{Circle around (7)} When the end of the work is notified to the monitoring center 100, the information is deleted by an operation from the monitoring center 100 (a deletion command is transmitted from the monitoring center 100 to the portable terminal 1).
[0083]
Regarding the handling of key data, both locking and unlocking operations may be prohibited by erasing key data or the like, but only unlocking operations may be prohibited. This is because, although there is a possibility of being misused by unauthorized unlocking, the possibility of being misused by improper locking is extremely low.
[0084]
(14) Breakdown of key data
The following are assumed as breakdowns of key data. Select and use the following information as needed.
[0085]
(1) Identification information
This information is used for collation in the control device on the lock side when the lock is unlocked. For example, it is the same information as the information sent to a card reader or the like when the lock is unlocked and unlocked using a device other than the portable terminal, such as identification information, a personal identification number, and a personal ID code transmitted from a non-contact card.
(2) Lock information (ID) of the lock to be locked / unlocked
Used to check whether the target lock is correct when performing locking and unlocking.
(3) Key data erasure conditions
Used to change the erasure condition according to the situation such as the number of valid times and the valid period. If the object to be locked / unlocked is the entrance door of the building, it is sufficient to be able to lock and unlock only once, but if a common key is required at the entrance door on each floor, it must be locked and unlocked multiple times.
In such a case, the validity period (for example, 2 hours) may be determined based on the required work time instead of the number of times.
(4) Name of lock
When locking and unlocking a plurality of locks, it is used when a security guard selects an unlocking signal in accordance with the lock to be unlocked, and is, for example, a name such as "building entrance door" or "○ floor entrance door". That is, when locking and unlocking a plurality of locks with a mobile terminal, the security guard must select and specify where to lock and unlock. This is the name of the lock to be used at that time.
[0086]
(15) Configuration and operation of retrofit electric lock
Next, the configuration and operation of a retrofit electric lock which is a feature of the present invention will be described. The lock apparatus according to the present invention additionally installs an electric lock at the cylinder lock, and changes the lock to be unlocked and unlocked by the electric lock when a security guard or a maintenance person unlocks the lock. When the contractor performs locking and unlocking, the conventional key is used as it is to lock and unlock. With this configuration, the trouble of exchanging the key with the one currently used by the contracted party is eliminated. The electric lock to be additionally installed is effective when power is supplied from a battery carried by a security guard, instead of constantly supplying power, and is locked and unlocked by a signal from a portable terminal. Eliminates large-scale wiring work and reduces installation costs.
[0087]
That is, the above-mentioned retrofitted electric lock uses an electric lock to rotate the cylinder outside the cylinder lock so that the mobile terminal can lock and unlock the lock even if the contractor has already used the cylinder lock. A lock portion for restricting the movement is provided, and a human rotates the cylinder with an existing key after the lock is released. Hereinafter, a specific description will be given with reference to FIGS.
[0088]
FIG. 8 is a block diagram illustrating a configuration example of the portable terminal and the retrofitted electric lock according to the embodiment of the present invention. FIG. 9 is an explanatory diagram illustrating a configuration example of the portable terminal and the retrofitted electric lock according to the embodiment of the present invention. FIG. FIG. 10 is an explanatory diagram showing an example of assembling a retrofit electric lock to a door according to the embodiment of the present invention.
[0089]
As shown in these drawings, the mobile terminal 1 includes a power supply unit 140 in addition to the functions of the transmission / reception unit 16 described above. Further, the retrofit electric lock 150 includes a transmitting / receiving unit 101, a control unit 102, an authentication unit 103, a driving unit 104, a lock unit 105, a cylinder unit 106, and a power receiving unit 107. 9 and 10, reference numeral 60 denotes a power supply terminal, reference numeral 110 denotes a simple key for rotating the cylinder after unlocking, and reference numeral 200 denotes an entrance door. Reference numeral 90 in FIG. 10 denotes a lock shaft which is locked / unlocked by the lock portion 105, and reference numeral 91 denotes a deadbolt which projects / retreats from the end face of the entrance door 200 to lock and unlock (finally tighten) the building and the entrance door 200. Reference numerals 95a and 95b are door knobs. It should be noted that the simple key 110 is, for example, a key having a straight shape without a key peak, and may have any shape as long as it can be inserted into a cylinder and can rotate.
[0090]
The power supply terminal 60 is connected and used as a relay connector when power is supplied from the power supply unit 140 of the portable terminal 1 to the power receiving unit 107 of the retrofit electric lock 150. The power from the power supply unit 140 to the power receiving unit 107 is power enough to release the lock unit 105, for example, about 3 V / 300 mA at which a biometal fiber (artificial muscle) can operate as described later. On the other hand, conventionally, in order to rotate the cylinder by driving the motor, power supply of about 12 V / 1 A is required.
Therefore, in the present invention, it has been confirmed by trial manufacture that the lock portion is driven only by supplying the small voltage, and as a result, low voltage and power saving can be achieved.
[0091]
The control unit 102 operates with the power received by the power receiving unit 107, controls the driving unit 104, and releases the lock of the lock unit 105. In this release, the authentication unit 103 and the like are performed with the mobile terminal 1 to prevent unauthorized locking and unlocking. The cylinder portion 106 unlocked by the lock portion 105 is manually rotated by the insertion of the simple key 106 and unlocked. That is, the door knob 95a becomes rotatable, and the rotation causes the dead bolt 91 to retreat from the door end face, and the door is opened. The contractor locks and unlocks the lock using a normal key as in the past.
[0092]
In this manner, the ID code is transmitted to the retrofitting electric lock 150 via the transmitting / receiving unit 16 of the portable terminal 1. Further, when the authentication unit 103 confirms that the ID code is a valid ID code, the control unit 102 switches the lock unit 105 from the locked state to the unlocked state by the driving unit 104 and inserts the simple key 110 Is turned to make it unlockable. That is, the lock of the cylinder unit 106 is released using a portable terminal, and a simple key is inserted into the cylinder and turned to unlock the cylinder lock. By unlocking the cylinder lock, the door knob becomes rotatable, The door is opened by operating the door knob.
