TECHNICAL FIELD OF THE INVENTION
The present invention relates to a security system that manages, for example, gate traffic.
[0002]
[Prior art]
2. Description of the Related Art In a security system that manages the passage of a gate (entering and exiting a building) and the use of equipment, a password is often used as a means for authenticating a person (individual, group, etc.).
[0003]
For example, in the case of a security code type lock, the security code input at the installation location of the lock is collated with a mechanically or electrically registered security code in advance, and if the collation results match, the person is an authorized person. Authentication is made and unlocking (or locking) is performed. If the collation results do not match, the person is authenticated as a non-permitted person, and the unlocking (or locking) is rejected.
[0004]
[Problems to be solved by the invention]
If the password is leaked to the outside, there is a concern that unauthorized unlocking may be performed by a third party.
If a large number of security locks are installed, it is difficult to store a large number of security codes, so a security code book is created and brought to the place where the locks are installed. If the security code book is lost, the security code is leaked, which is a serious security problem.
[0005]
Even if it is not a leak, a person who knows the password once can unlock it even if he or she has no right to go through the gate due to retirement.
The present invention has been made in view of the above circumstances, and an object thereof is to provide a security system capable of preventing a leak of a personal identification number or an unauthorized traffic by a retired employee, for example, and improving safety and reliability. To provide .

[0010]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
As shown in FIG. 1, for example, a security device 1 is installed as a means for managing the passage of a gate (exiting and entering a building).
[0011]
The security device 1 includes a center device 2, which connects a connection device 3 for a wireless telephone line and a gate device 4 to the center device 2, and further includes a numeric keypad 5, which is an operation means, and a notification device to the gate device 4. However, the alarm generator 6 is connected.
[0012]
A unique telephone number is defined in the center device 2, and a connection / disconnection of a wireless telephone line between the connection facility 3 and an external portable telephone 10 is performed based on the telephone number.
[0013]
The portable telephone 10 is a portable telephone using a wireless telephone line, and includes a simplified portable telephone called PHS. In addition, a unique telephone number is defined for the mobile phone 10, and this telephone number is protected by high security for duplication.
[0014]
The center device 2 includes a permission data memory 2a, a random number generator 2b, and a personal identification number memory 2c, and includes the following [1] to [3] as main functional means.
[0015]
[1] Setting means for variably setting a password. Specifically, a random number is generated from the random number generator 2b at an arbitrary time or as required by a staff member, and a password is set using the random number.
[0016]
[2] Storage means for updating and storing the personal identification number set by the setting means in the personal identification number memory 2c.
[3] Notifying means for notifying the personal identification number in the personal identification number memory 2c to the specific person in response to a request from the specific person. Specifically, in response to the call from the mobile phone 10, the telephone number of the mobile phone 10 is compared with the permission data (registered phone number) in the permission data memory 2a. Then, the caller is determined to be a specific person and a password is notified, and in the case of a mismatch, the caller is determined to be a non-specific person and rejection is notified to the portable telephone. The registered telephone number, which is the permission data in the permission data memory 2a, is the telephone number of the mobile phone 10 owned by the specific person (registrant) for the security, and is input in advance by the operation of the attendant.
[0017]
The gate device 4 includes the following [4] and [5] as main functional means.
[4] Authentication means for receiving a password from the password memory 2c of the center device 2 when a password is input by operating the numeric keypad 5, and authenticating a person by collating the password with the input password. Specifically, the input personal identification number is compared with the personal identification number in the personal identification number memory 2c, and when the collation result matches, the ten-key operator is authenticated as an authorized person. Authenticate as an authorizer.
[0018]
[5] Control means for transmitting a gate opening signal when the authentication means has authenticated the authorized person, and for generating an alarm sound from the alarm generator 6 when authenticating the non-authorized person. The gate opening signal unlocks the lock provided at the entrance of the building or the like.
[0019]
Next, the operation of the above configuration will be described with reference to the flowchart of FIG.
When a change trigger related to a password is generated (YES in step 101), for example, when a predetermined time based on timer measurement is reached, or when a change operation of the password is performed by a staff member, a random number is generated from the random number generator 2b. Then, a new password is set from the random number (step 102). The new password set is updated and stored in the password memory 2c (step 103).
[0020]
A person who wants to know the current new personal identification number inputs the telephone number of the center apparatus 2 to the portable telephone 10 owned by the user and makes a call. This transmission is sent to the connection facility 3 as a password notification request.
[0021]
The connection facility 3 responds to the incoming call of the personal identification number notification request (YES in step 104), and establishes a connection with the mobile phone 10 via a wireless telephone line (step 105).
When the wireless telephone line is connected, the telephone number of the caller is notified to the center device 2 by the calling number notification service of the telephone company. Then, the notified caller telephone number is compared with the permission data in the permission data memory 2a, that is, the registered telephone number (step 106).
[0022]
If the caller's telephone number matches any of the registered telephone numbers (YES in step 107), it is determined that the caller is a specific person (registrant), and the personal identification number in the personal identification number memory 2c is changed to the mobile telephone. The device 10 is notified (step 108). Then, the wireless telephone line is disconnected (step 109).
[0023]
However, as shown in FIG. 3, if the caller is a non-specific person (non-registered person), the caller's telephone number does not match any of the registered telephone numbers (NO in step 107). In this case, based on the determination that the caller is a non-specified person (non-registered person), the rejection is notified to the mobile phone 10 (step 110). Then, the wireless telephone line is disconnected (step 109).
[0024]
When the caller's telephone number is compared with the registered telephone number, a caller-specific ID number (for example, a personal identification number) is input from the mobile phone 10 and the match between the caller's telephone number and the registered ID number is determined by the specific person. If added to the (registrant) determination condition, the degree of security is increased, and even if the mobile phone 10 is lost, its abuse can be prevented.
[0025]
On the other hand, a person who wants to enter the building goes to the place where the gate device 4 is installed and operates the numeric keypad 5 to input a password.
When the personal identification number is input (step 111), the current new personal identification number is fetched from the personal identification number memory 2c into the gate device 4 (step 112), and is compared with the inputted personal identification number (step 113). ).
[0026]
If the collation results match (YES in step 114), a gate opening signal is transmitted after the ten-key operator is authenticated as a permitter (step 115). When the gate opening signal is transmitted, the lock at the entrance of the building is unlocked, and the ten-key operator can enter the building.
[0027]
However, if the collation results are inconsistent (NO in step 114), the ten-key operator issues an alarm sound from the alarm generator 6 under authentication with a non-permitted person (step 116). This alarm sound informs that the person trying to enter the building is a suspicious person.
[0028]
In this way, the personal identification number is changed and set at an arbitrary time or as necessary, and the same is notified to the specific person in response to a request from the specific person. By authenticating a person by collating with a new PIN, even if the PIN (old PIN) leaks outside, unauthorized unlocking and passage by a third party can be avoided, and security and Reliability can be improved.
[0029]
If a large number of PIN locks are installed, it is difficult to store a large number of PINs, so it is necessary to create a PIN book and bring it to the place where the locks are installed. Even if the personal identification number book is lost and the personal identification number is leaked, unauthorized unlocking and passage by a third party can be avoided.
[0030]
Even if a person who has lost the right to pass through the gate due to retirement or the like attempts to unlock illegally, the security code known to that person will be an old security code that does not work at this time, so improper unlocking and traffic Can be prevented.
[0031]
In addition, in response to the call from the mobile phone 10, the phone number of the mobile phone 10 is compared with the registered phone number, the specific person is determined based on the comparison, and only the specific person is notified of the new password. Therefore, high security and reliability can be ensured also in this regard.
[0032]
In the above embodiment, the center device 2 and the gate device 4 may be either installed in the same building or not installed in the same building. When not installed in the same building, the center device 2 and the gate device 4 are connected by a telephone line for remote control.
[0033]
In the above embodiment, one gate device 4 is connected to one center device 2. However, a plurality of gate devices 4 are connected to one center device 2, and one of the gate devices 4 is controlled by one of the gate devices 4. Alternatively, a configuration may be adopted in which selection is made by voice response processing between the registrant and the center device 2.
[0034]
Further, in the above-described embodiment, the case where a mobile phone is used as a means for knowing a personal identification number has been described as an example. The same applies to the case where a telephone is used.
In addition, the present invention is not limited to the above embodiments, and various modifications can be made without departing from the scope of the invention.
[0035]
【The invention's effect】
As described above, according to the present invention, it is possible to provide a security system in which security and reliability can be improved by preventing leakage of a personal identification number and illegal traffic by a retired employee, for example.
