Description

  The present invention relates to a card issuing system for an electric lock that issues a locking / unlocking card used in a card lock system that electrically controls locking / unlocking based on whether key information stored in advance is valid or not.

  Conventionally, for the purpose of improving security such as unauthorized intrusion from outside and privacy protection, for example, entrances and entrances to apartment buildings and ordinary houses, public facilities such as government offices and commercial facilities such as office buildings, card type Card lock systems using electric locks are widely used.

  This card lock system uses a card-like storage medium in which various kinds of card information such as specific code and lock / unlock information pre-assigned to each electric lock at each place are stored as a lock / unlock card, and is stored in the lock / unlock card. The key information (for example, locking / unlocking data with a specific encryption) is read, and the read card information is compared with previously registered information to determine the validity. And only when it authenticates normally, the lock is electrically locked / unlocked according to the lock state at that time (door open / closed state, lock / unlock state before lock).

  Accordingly, the card lock system is trusted in terms of security because it prevents unauthorized locking / unlocking actions such as picking and it is very difficult to duplicate keys. In addition, since various data for each locking / unlocking card is managed by the host computer, there is no fear of data corruption and the locking / unlocking card can be reissued even if the locking / unlocking card is lost. As a card lock system using this type of card type electric lock, for example, one disclosed in Patent Document 1 below is known.

Japanese Examined Patent Publication No. 58-51593

  By the way, the locking / unlocking card used for locking / unlocking the card-type electric lock is usually produced in a lump at the manufacturer's factory, and key information is written to each card at the time of manufacture. However, when key information is written to the lock / unlock card at the manufacturing factory, the lock / lock card must be strictly managed to prevent leakage of key information and duplication. It was.

  When manufacturing a locking / unlocking card, for example, “00001” for the first locking / unlocking card, “00002” for the second locking / unlocking card, etc. In many cases, regular information is used. Therefore, when a lock / unlock card is delivered to a large-scale office building or apartment complex, it will be delivered to the property in a unified form. For example, if the key information of the lock / unlock card has been analyzed Other key information can be easily guessed, and there is a possibility that the locking / unlocking card is illegally issued.

  Accordingly, the present invention has been made in view of the above-described problems, and is capable of issuing an electric lock card that can simplify the management of the lock / unlock card and prevent unauthorized issuance of the lock / unlock card by analyzing the key information. The purpose is to provide a system.

In order to achieve the above-described object, the electric lock card issuing system according to claim 1 is a card lock system that controls the lock electrically only when the validity of the key information is determined and it is normally authenticated. An electric lock card issuing system for issuing a used locking / unlocking card,
The locking / unlocking card has a first storage area in which identification information as the key information for identifying the locking / unlocking card is written, and key ID information as the key information randomly generated for each locking / unlocking card Has a storage section that is at least partitioned from the second storage area in which is written,
A key ID generating means for randomly generating the key ID information for each locking / unlocking card, and a state determining means for determining whether or not the second storage area of the locking / unlocking card is empty, An information reader is provided for writing the generated key ID information to the second storage area when it is determined that the second storage area of the locking / unlocking card is empty.

The electric lock card issuing system according to claim 2 is the electric lock card issuing system according to claim 1,
When the information reader / writer determines that the key ID information has already been written in the second storage area of the locking / unlocking card and the state determination means determines that the existing key ID information needs to be overwritten Overwrites the generated key ID information.

There is no need to strictly manage so that duplicate accidents do not occur, and management operation is simplified.

  In addition, since the key ID information is randomly generated for each locking / unlocking card in the information reader, the key information of the locking / unlocking card delivered together is analyzed in the unlikely event because the information is written in the second storage area. Even in such a case, it is difficult to guess other key information, and an effect of reducing the risk of illegally issuing a locked / unlocked card is obtained.

It is a schematic block diagram for demonstrating the structure of the card issuing system for electric locks which concerns on this invention. It is a flowchart figure for demonstrating the processing operation of the system.

  Hereinafter, embodiments for carrying out the present invention will be described in detail with reference to the accompanying drawings.

[Configuration of the card issuing system for electric locks]
First, the configuration of the electric lock card issuing system according to the present invention will be described with reference to FIG.

  As shown in FIG. 1, an electric lock card issuing system 1 of this example is used in a general card lock system employed in a large-scale commercial facility such as an apartment house such as a condominium, a hotel or an office building. The locking / unlocking card 10 which is sometimes operated in a predetermined manner is issued. As shown in the figure, the electric lock card issuing system 1 includes a locking / unlocking card 10 and an information reader 20.

  The locking / unlocking card 10 is equipped with, for example, an IC card (RFID tag) including an IC card capable of reading and writing various data in a memory of a processor chip, a CPU, a ROM, a RAM, a flash RAM, etc. It is composed of a card-like storage medium having a storage unit 11 capable of storing / rewriting various kinds of information, such as a possible non-contact IC chip built-in card.

  The storage unit 11 is divided into at least two storage areas (a first storage area 11a and a second storage area 11b) in order to individually store identification information and key ID information, which are key information necessary for locking and unlocking. . In the first storage area 11a, identification information for identifying each card at the manufacturing factory when the card is manufactured is written. Further, the key ID information generated by the information reader 20 is written in the second storage area 11b when the area is empty (NULL) or when the existing key ID information is overwritten.

  Here, key information (identification information, key ID information) stored in each area of the storage unit 11 will be described with a specific example. The various information described below is an example, and does not limit the key information according to the present invention.

<Identification information>
The identification information is information that is stored in the first storage area 11a and has continuity that enables identification of each card such as a serial number in manufacturing or a serial number in manufacturing order. As an example of the identification information, “000001” in the first locking / unlocking card 10, “000002” in the second locking / unlocking card 10, “00000n” in the nth locking / unlocking card 10, etc. Numbers are stored on each card. Thereby, since the identification information which has the continuity allocated for every manufactured locking / unlocking card is written in the 1st storage area 11a, management operation of a manufacturer becomes easy.

  As another example of the identification information described above, information having regularity such as a manufacturing date, a manufacturing device number, and an issuing serial number in a card manufacturing factory that can be identified by the card issuer may be used. As an example, “09001010001” is assigned to the first locking / unlocking card 10, “090010101002” is assigned to the second locking / unlocking card 10, and “09001010100n” is assigned to the nth locking / unlocking card 10. In this case, the identification information from the left is “09” for the year, “01” for the month, “01” for the day, “01, 02, 0n” for the machine number of the issuing device, “001, 002, 00n”. As an issue serial number. As a result, the unique identification information assigned to each locking / unlocking card is written in the first storage area but has no continuity like the manufacturing number, so that the management operation of the manufacturer is facilitated.

<Key ID information>
The key ID information is random information such as a random number stored in the second storage area 11b and generated by the information reader 20, and the unlocking card 10 in a state where the identification information is stored in the first storage area 11a. Is written against. As an example of the key ID information, “568413” is stored in the first locking / unlocking card 10 and “369248” is stored in the second locking / unlocking card 10. As a result, the second storage area 11b is empty when the card is manufactured, and the key ID information unique to each lock / unlock card 10 generated when the key ID information is written is written to the second storage area 11b. Management operation is simplified.

  The information reader / writer 20 reads / writes locking / unlocking information stored in various locking / unlocking cards 10 such as a magnetic card, an IC card, a non-contact IC chip built-in card, for example, various types such as a swipe type, an insertion type, and a non-contact type. It is composed of a card reader / writer having an information reading function. The information reading device 20 includes an information reading means 21, a key ID information generation means 22, a state determination means 23, an information storage means 24, a process control means 25, and a display means 26.

  The information reading / writing means 21 reads / writes key information stored in the locking / unlocking card 10 under the control of the processing control means 25. Specifically, the reading process of the identification information stored in the first storage area 11a of the locking / unlocking card 10, the reading process of the key ID information already stored in the second storage area 11b, and the key for the second storage area 11b ID information is written or overwritten.

  The key ID information generation unit 22 generates random numbers or the like for each lock / unlock card 10 at random when writing the key ID information to the lock / unlock card 10 under the control of the process control unit 25. Is generated.

  Under the control of the processing control means 25, the state determination means 23 determines whether or not the second storage area 11b of the lock / unlock card 10 operated during the key ID information writing process is empty (NULL). The status information is output to the process control means 25.

  The information storage means 24 is composed of, for example, a magnetic or optical storage medium or a semiconductor memory such as ROM or RAM. The information storage unit 24 stores the identification information stored in the locking / unlocking card 10 and the generated key ID information as key information of the operated locking / unlocking card 10 under the control of the processing control unit 25. Further, when the key ID information already stored in the locking / unlocking card 10 is not overwritten, the information storage means 24 identifies the identification information stored in the locking / unlocking card 10 and the existing key ID information. Is stored as key information of the operated locking / unlocking card 10.

  The processing control means 25 is composed of a microcomputer such as a CPU, RAM, or ROM. The processing control means 25 controls the generation process of the key ID information to be written to the locking / unlocking card 10 based on the state information from the state determining means 23 and a predetermined operation by the operator, and the empty state of the second storage area 11b of the locking / unlocking card 10 Discriminating process control, control of reading process of key information stored in the locking / unlocking card 10, control of writing or overwriting of key ID information generated by the key ID information generating means 22, identification information of the locking / unlocking card 10 and The process control of each part which comprises the information reader 20 is performed, such as the registration process of key ID information, and the control of the display process with respect to the display means 26.

  The display means 26 is composed of a display device such as an LED or a liquid crystal screen. Under the control of the processing control means 25, the display means 26 is displayed in an identifiable manner by the operator based on the state of the second storage area 11b of the locking / unlocking card 10 (LED lighting / flashing display, color-specific display, character display on the liquid crystal screen) Display).

  Note that the information reading device 20 may be configured to be used in a card issuing device installed in, for example, a hotel front or condominium management room, in addition to use as a single device.

[Processing of the card issuing system for electric locks]
Next, processing operations in the above-described electric lock card issuing system will be described with reference to FIG.

  When the operator starts the key ID information writing process, the operator first generates random key ID information (ST1). Next, it is determined whether or not the second storage area 11b of the operated locking / unlocking card 10 is empty (ST2).

If the second storage area 11b is empty (ST2-Yes), the key ID information generated in ST1 is written to the second storage area 11b (ST3). Then, the authentication information and key ID information stored in the locking / unlocking card 10 are registered in the information reader 20 as the key information of the locking / unlocking card 10 (ST4), and the process ends.
On the other hand, if the second storage area 11b is not empty (ST2-No), since the key ID information is already stored in the second storage area 11b, the operator selects whether to overwrite the key ID information. (ST5).

When the key ID information is overwritten in ST5 (ST5-Yes), the process proceeds to ST3 in order to write the key ID information generated in ST1.
On the other hand, when the key ID information is not overwritten (ST5-No), the existing key ID information that has been written is used, and thus the generated key ID information is discarded (ST6). Then, the authentication information and key ID information already stored in the locking / unlocking card 10 are registered as key information of the locking / unlocking card 10 (ST7), and the process is terminated.

  In this way, the above-described electric lock card issuing system writes identification information for identifying each lock / unlock card 10 in the first storage area 11a at the time of card manufacture, and the second storage area 11b in which the key ID information is written. Manufacture in an empty state. When the key ID information is written, the key ID information for each locking / unlocking card 10 is randomly generated. When it is determined that the second storage area 11b of the locking / unlocking card 10 is empty, the second storage area 11b Is generated.

  Accordingly, since the lock / unlock card 10 can be managed in a state where the key ID information which is key information is not stored in the card manufacturing factory, it is strictly managed so as not to cause leakage of key information and duplicate accidents. There is no need.

  Further, even when the manufactured locking / unlocking card 10 is delivered collectively, after the delivery, after the key ID information is randomly generated for each locking / unlocking card 10 in the information reader / writer 20, the information is written in the second storage area 11b. Therefore, even if the key information of the locking / unlocking card 10 has been analyzed, it is difficult to guess the other key information, and the risk that the locking / unlocking card 10 is illegally issued can be reduced. it can.

  By the way, in the processing content shown in FIG. 2 described above, the key ID information generation processing (ST1) may be performed after the determination processing (ST2) of whether or not the key ID information is written. In this case, the process of discarding the generated key ID information (ST6) performed after the process of determining not to overwrite the existing key ID information (ST5-No) is omitted without necessity, and the processing operation is simplified. can do.

  In addition, in the storage unit 11 of the locking / unlocking card 10, an operation information storage area for writing an operation history of locking / unlocking and abnormality information at the time of locking / unlocking operation as necessary for the purpose of improving the use environment and security. Can also be secured.

  Furthermore, in the above-described embodiment, the identification information for identifying the locking / unlocking card 10 has been described as being stored in the first storage area 11a. However, the identification information is further formed on the bill surface of the locking / unlocking card 10 (printing on the printing device or the like). (Embossed engraving or the like) saves the trouble of reading the identification information stored in the card each time the locking / unlocking card 10 is identified, thereby further simplifying the card management operation.

  As mentioned above, although the best form in this invention was demonstrated, this invention is not limited with the description and drawing by this form. That is, it is a matter of course that all other forms, examples, operation techniques, and the like made by those skilled in the art based on this form are included in the scope of the present invention.
