DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS [0027] The embodiments of the present invention will be described with reference to the accompanying drawings. In the drawings, the same or equivalent parts are denoted by the same reference numerals, and the redundant description thereof is appropriately simplified or omitted.

Embodiment 1

1 is a block diagram of an entry / exit management system according to a first embodiment of the present invention.

1, reference numeral 1 denotes a management area such as a building. A user of the management area (1) carries the authentication medium (2). The authentication medium 2 is composed of a portable magnetic recording member or a memory. In the authentication medium 2, a unique card ID number is stored as individual identification information for identifying an identification object. In the authentication medium 2, a unique user ID, a password, a date of birth of the user, an expiration date, and the like may be stored as the individual identification information.

The management area 1 can be divided into a plurality of management areas (not shown). Each management area is provided with an entrance (not shown). Each doorway is provided with a door (not shown). Each door is provided with an electric lock (not shown). In the vicinity of each entrance, an authentication terminal 3 is provided corresponding to each electric lock. Each authentication terminal 3 is connected to the management apparatus 5 via the communication network 4. [

Next, the authentication terminal 3 will be described in detail.

The authentication terminal 3 includes a terminal I / F section 3a, a communication I / F section 3b, an electric lock I / F section 3c, a storage section 3d, and a terminal control section 3e.

The terminal I / F section 3a has a function of reading out the individual identification information from the authentication medium 2. The communication I / F section 3b has a function of communicating with the outside via the communication network 4. [ The electric lock I / F portion 3c has a function of controlling a corresponding electric lock. The storage unit 3d has a function of storing a program for entering / leaving management. The terminal control unit 3e has a function of reading out and executing the program of the storage unit 3d to perform entrance / exit management.

Next, the management apparatus 5 will be described in detail.

The management device 5 comprises a computer such as a server or a PC. The management apparatus 5 includes a communication I / F unit 5a, an operation input unit 5b, a screen display unit 5c, a storage unit 5d, and a management control unit 5e.

The communication I / F unit 5a has a function of communicating with the outside through the communication network 4. [ The operation input unit 5b is composed of a keyboard, a mouse, and the like. The screen display section 5c includes a display device such as a CRT or an LCD. The screen display section 5c is provided with various information necessary for entering / leaving management and a function of displaying an unauthorized operation occurrence alarm upon detection of unauthorized operation (illegal passage).

The storage unit 5d functions as storage means for storing various data used for various processes. More specifically, the storage unit 5d stores the movement time table 5f and the operation history table 5g. In the movement time table 5f, reference times for movement between the authentication terminals 3 are stored. In the operation history table 5g, the ID of the authentication terminal 3 that has performed the operation and the operation time are stored in association with each user ID of the individual identification information.

The management and control section 5e has a function of performing various processes relating to entering and leaving the respective management zones. Specifically, the management control means 5e functions as an authentication means for authenticating the user based on the movement time table 5f and the operation history table 5g.

Next, the basic operation of the entry / exit management system will be described.

First, the case where the user enters the management area 1 for the first time or the case where the system is reset will be described. In this case, the user brings the authentication medium 2 to the terminal I / F unit 3a of the authentication terminal 3 corresponding to one of the management zones. The terminal I / F unit 3a of the authentication terminal 3 reads person identification information from the authentication terminal 3. [

The read personally identifiable information is transmitted to the communication I / F unit 5a of the management apparatus 5 via the communication I / F unit 3b and the communication network 4 of the authentication terminal 3. The storage unit 5d of the management apparatus 5 stores the ID of the operated authentication terminal 3 and the operation time (identification time) in the operation history table 5g in association with the user ID of the transmitted personal identification information .

Thereafter, the user moves to another management zone and brings the authentication medium 2 to the terminal I / F unit 3a of the authentication terminal 3 corresponding to the management zone of the movement destination. The terminal I / F unit 3a of the destination authentication terminal 3 reads the individual identification information from the authentication medium 2. [ The read personal identification information is transmitted to the communication I / F unit 5a of the management apparatus 5 via the communication I / F unit 3b and the communication network 4 of the destination authentication terminal 3 .

The management control unit 5e of the management apparatus 5 receives the operation notification from the authentication terminal 3 of the destination through the communication I / F unit 5a. The management control unit 5e of the management apparatus 5 then transmits the ID of the authentication terminal 3 operated immediately before by the user based on the user ID of the individual identification information to the ID of the source authentication terminal 3 And acquires the operation time at the source authentication terminal 3. [

The management control unit 5e of the management apparatus 5 then uses the operation time in the source authentication terminal 3 and the operation time in the destination authentication terminal 3 to perform the operation As an estimated movement time.

The management control unit 5e of the management apparatus 5 then refers to the movement time table 5f based on the ID of the source authentication terminal 3 and the ID of the destination authentication terminal 3, (3) is obtained. Thereafter, the management control unit 5e of the management apparatus 5 compares the estimated movement time with the reference time.

For example, when the estimated movement time is shorter than the reference time, the user moves between the two authentication terminals 3 in a time shorter than the reference time. This movement is not realistic. For this reason, the management control unit 5e of the management apparatus 5 determines that there is an unauthorized operation. In this case, the electric lock of the management area of the transfer destination is not opened. This prevents illegal intrusion into the management area of the transfer destination.

In this manner, the reference time must be registered in the movement time table 5f in association with the ID of the authentication source terminal 3 of the movement source and the movement destination. In order to register this reference time in advance, it is necessary to measure in advance a movement time necessary for moving between the authentication terminals 3. Therefore, when the number of the authentication terminals 3 is large and when the arrangement of the authentication terminal 3 is changed, when the authentication terminal 3 is newly added, efforts to register the reference time are very large.

Therefore, in the present embodiment, the management apparatus 5 is provided with the movement time table creation / change means (update means) 5h, and the statistics of the differences in the identification times of the respective user IDs in the different authentication terminals 3 And the reference time is updated based on the value. Hereinafter, a method of updating the reference time will be described.

First, the movement time table 5f of the present embodiment will be described with reference to Fig.

2 is a diagram for explaining a movement time table of the entry / exit management system according to the first embodiment of the present invention.

As shown in Fig. 2, the ID of the authentication terminal 3 of the source and the ID of the authentication terminal 3 of the movement destination are associated with each other in the movement time table 5f. In making this correspondence, the pointer value is also associated. Corresponding to this pointer value, a difference between the authentication time of the authentication terminal 3 of the source and the authentication time of the authentication terminal 3 of the migration destination is stored as the actual value.

The movement time table creation and change means 5h calculates the statistical values of these actual values. More specifically, moving average, standard deviation, and variation coefficient are calculated as statistical values. These statistical values are stored in the movement time table 5f in correspondence with the authentication terminal 3 of the source and the authentication terminal 3 of the movement destination.

As an example, a description will be given of a case where the first terminal is set as the movement source and the second terminal is set as the movement destination. In this case, the measured value corresponding to each pointer value is "300" (second), ... , &Quot; 308 " (second). At this time, the average is 303.0 (seconds). The standard deviation at this time is 16.6. The coefficient of variation at this time is 5.48.

Next, a method of calculating the statistical value will be described in detail with reference to FIG.

3 is a flowchart for explaining the operation of the entry / exit management system according to the first embodiment of the present invention.

First, in step S1, the movement time table creation and change means 5h receives an operation notification via the communication I / F unit 5a and the management control unit 5e of the management apparatus 5. [ Thereafter, the movement time table creation and change means 5h acquires the user ID of the operation notification and the ID of the authentication terminal 3 and updates the ID of the authentication terminal 3 to the ID of the movement destination authentication terminal 3 of the user . Thereafter, the process proceeds to step S2, and the movement time table creation / modification means 5h determines whether or not the previous history of the received user ID exists in the operation history table 5g.

If the history of the received user ID does not exist, the movement time table creation / change means 5h ends the operation. If there is a history of the received user ID, the process proceeds to step S3. In step S3, the movement time table creation and change means 5h acquires the ID of the authentication terminal 3 at that time and stores it as the ID of the source authentication terminal 3. [

Thereafter, the process proceeds to step S4. The movement time table creation / modification means 5h calculates the difference between the operation time at the source authentication terminal 3 and the operation time at the movement destination authentication terminal 3, . Thereafter, the process proceeds to step S5. In step S5, the movement time table creation / change unit 5h changes the movement time table creation / update unit 5h so that the ID of the source authentication terminal 3 and the ID of the movement destination authentication terminal 3 in the movement time table 5f are It refers to the pointer value.

After that, the flow advances to step S6, and the movement time table creation and change means 5h changes the value of the column corresponding to the pointer value from the measured value of the corresponding row of the movement time table 5f to the calculated movement time. Thereafter, the process proceeds to step S7, and the movement time table creation / modification means 5h performs update processing of the pointer value. More specifically, the movement time table creation and change means 5h determines whether the referenced pointer value is smaller than N. [

If the pointer value is smaller than N, the flow advances to step S8. In step S8, the movement time table creation changing means 5h increments the pointer value by one. Thereafter, the flow advances to step 9, and the movement time table creation and change means 5h updates the pointer value of the corresponding row of the movement time table 5f. Thereafter, the process proceeds to step S10, in which the movement time table creation and change means 5h recalculates the moving average, the standard deviation and the variation coefficient as statistical values and stores the calculation result in the corresponding row of the movement time table 5f do.

On the other hand, if the pointer value referenced in step S7 is N, the process proceeds to step S11. In step S11, the movement time table creation changing means 5h sets the pointer value to 1. Thereafter, the flow advances to step S9, and the movement time table creation changing means 5h returns the pointer value of the corresponding row of the movement time table 5f to 1. Thereafter, the process proceeds to step S10, in which the movement time table creation and change means 5h re-calculates the moving average, the standard deviation, and the variation coefficient as statistical values, and stores the calculation result in the corresponding row of the movement time table 5f do.

This operation is performed each time each user operates each authentication terminal 3. Therefore, each time the different authentication terminals 3 identify the identification objects successively, the difference of the identification time between the corresponding authentication terminals 3 is stored in the movement time table 5f.

Next, an example of a method of setting the reference time will be described.

In the present embodiment, the value of the mean value-standard deviation x 3 is set as the minimum movement time. On the other hand, a value of average value + standard deviation x 3 is set as the maximum movement time. The minimum movement time and the maximum movement time are calculated corresponding to each combination of the authentication terminal 3 of the mobile origin and the authentication terminal 3 of the movement destination. These calculation results are stored in the movement time table 5f in association with each combination of the authentication terminal 3 of the source and the authentication terminal 3 of the movement destination.

Based on the reference time thus set, the management control unit 5e of the management apparatus 5 determines whether or not an unauthorized operation has been performed. More specifically, the management control unit 5e of the management apparatus 5 determines that there is an unauthorized operation when the calculated movement time is shorter than the minimum movement time or longer than the maximum movement time.

According to the first embodiment described above, the reference time corresponding to the actual movement time is automatically set based on the statistical value of the difference of the identification time of the authentication terminal 3. Therefore, it is unnecessary to measure the moving time between the authentication terminals 3 in advance. When the arrangement of the authentication terminal 3 is changed, it is not necessary to measure the reference time again. In addition, the reference time is updated. Therefore, the accuracy of the reference time can be improved.

In addition, when it is judged to be negative by the movement time, the movement time may not be stored in the movement time table 5f. In this case, it is possible to exclude the singular value from the population when the statistical value is obtained. As a result, the accuracy of the statistical value in the movement time table 5f is increased. Therefore, it is possible to further improve the accuracy of the entrance / exit management.

In addition, statistical values may be calculated for each user, for each sex, age group, wheelchair user, and the like. In this case, a reference time suitable for the attribute of the user can be set. At this time, by using the statistical value of the attribute of the user assumed to have a fast moving speed when setting the minimum moving time, and using the statistical value of the attribute of the user assumed to be slow in moving speed when setting the maximum moving time, It is possible to prevent the intrusion into the area.

In Embodiment 1, to simplify the calculation, the reference time is set using N moving averages. However, the reference time may be set using a simple arithmetic mean. Even in this case, the same effect as that of the first embodiment can be obtained.

It is also possible to copy one of the actual values until the actual values of the difference between the operation times between the authentication terminals 3 are set to be N, to obtain another actual value. In this case, since the introduction of the system, it is possible to manage the entrance and exit with a certain precision. On the other hand, if the determination of the unauthorized operation is prohibited until the measured value of the difference between the operation times between the authentication terminals 3 is N, the probability of misjudging the unauthorized operation can be reduced.

In addition, the setting of the reference time may be changed in consideration of the arrangement of each authentication terminal 3. For example, in the case of moving between management areas in contact with straight passages, the user is moved on foot as a rule. For this reason, it can be considered that the deviation of the movement time between the management zones is relatively small. In this case, the difference between the minimum movement time and the maximum movement time may be set relatively small. On the other hand, when moving between management areas of different floors, a staircase, an escalator, an elevator, or the like can be considered as moving means. In this case, the deviation of the movement time between the management zones can be considered to be relatively large. In this case, the difference between the minimum movement time and the maximum movement time may be set relatively large. In this case, it is possible to set a reference time appropriate for the arrangement of each authentication terminal 3.

Also, biometric authentication may be used for identification of an identification object. Even in this case, the same effect as that of the first embodiment can be obtained.

Embodiment 2 Fig.

Fig. 4 is a block diagram of an entry / exit management system according to the second embodiment of the present invention. The same or equivalent portions as those of the first embodiment are denoted by the same reference numerals, and a description thereof will be omitted.

The management apparatus 5 of the second embodiment is obtained by adding the illegal passage determination unit 5i to the management apparatus 5 of the first embodiment. The improper passing determination means 5i refers to an index (for example, a variation coefficient) indicative of a deviation of the difference in the identification time between the authentication terminals 3 and determines whether or not an unauthorized operation Or not. Specifically, when the referenced index is larger than the predetermined determination reference value, the improper passing determination means 5i functions as prohibiting means for inhibiting the determination of the tampering operation based on the statistical value.

According to the second embodiment described above, the management apparatus 5 makes a determination of an unauthorized operation only between the authentication terminals 3 with small deviation of the difference of the identification time. Therefore, the probability of misjudging false manipulation can be reduced.

It is also possible to set the minimum value of the measured value corresponding to the authentication terminal 3 between the authentication terminals 3 having a large deviation of the difference in the identification time as the minimum movement time, The maximum value of the measured value may be set as the maximum movement time. In this case, even between the authentication terminals 3 having a large deviation of the difference in the identification time, the entrance / exit can be managed with a certain precision.
