Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a management system using an IC card for wirelessly transmitting identification information and the like stored in a memory to a reading device, and more particularly to an IC capable of managing a suspicious person or the like by image data. Regarding card management system.

[0002]

2. Description of the Related Art Hitherto, there has been known a management system in which an IC card carried by a passer is used to enter and exit an area requiring security and to enter and exit the area. Such an IC card has a memory in which identification information and the like are stored. The identification information stored in the IC card is read by a reading device installed at the entrance of the area, and the identification information is compared with preset information. Authentication such as permitting entry / exit or managing entry / exit information.

[0003] Here, the information exchange method between the IC card and the reader is roughly classified into a contact method and a non-contact method. The contact method is a method in which a reading device and an IC card are brought into contact with a terminal or the like to exchange information between the two.
The non-contact method is a method in which a reader and an IC card perform wireless communication to exchange information between the two, and the IC card carrier holds the IC card over the reader, or the IC card carrier holds the IC card reader. Nearby (for example, 1
m), authentication by identification information can be performed.

[0004] Conventionally, a system using a surveillance video camera for managing entrance and exit has been implemented. In a system using this surveillance video camera, a sensor and a video camera are installed at the entrance and exit of the area, and when the sensor detects that something is approaching near the entrance, the video camera shoots an image recording the shooting time. This is a system that manages entrance and exit by storing a video tape on which the captured image is recorded.
That is, the image recorded on this videotape is called a time plus VTR, and when any problem or incident occurs, the suspicious individual is identified by the image recorded on the videotape, and The time of occurrence of the case can be specified by the recorded time.

[0005]

Here, in the conventional IC card management system, the purpose is to manage entrance / exit and entry / exit, and a function for managing a suspicious person before that is provided. Did not have. That is, contact type IC
In the card system, a person who intends to receive entry / exit authentication inserts the IC card into the reading device, and therefore always recognizes the necessity of the IC card. The suspicious individual was not managed by authentication in a natural state of action. Also,
In the non-contact type IC card system, authentication is performed only by carrying the IC card and passing near the reading device without special recognition. Authentication management.

[0006] However, regardless of whether the contact method is the contact method or the non-contact method, in such authentication management of the IC card only, when a problem or incident occurs, what kind of person and when It was not possible to determine how they acted.

To cope with such a problem, it is conceivable to use a system using a surveillance video camera as described above. The handleability is extremely poor, and the developability of the entire system is extremely poor. Specifically, images captured by a camera are simply recorded on a video tape in sequence on a video tape, and these recorded images are stored as they are without changing the form. It takes a lot of time to work. Also,
The video tape on which the image is recorded is stored in a warehouse or the like, but it cannot be accessed from another system or the like to effectively use the recorded image, and thus is useful only as storage information.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has been made by improving a surveillance camera system, and further integrating the improved surveillance camera system with a contactless IC card system. An object of the present invention is to provide an IC card management system that can realize various advantages that cannot be achieved by a conventional system. Further objects of the present invention will be apparent in the following description.

[0009]

An IC card management system according to the present invention includes a non-contact type IC card system.
It is a combination of a surveillance camera system that stores captured image data in a database format. Specifically, an IC card storing identification information for identifying a carrier has a wireless communication function, and a reading device is an IC card.
When the card is located in the vicinity, it wirelessly communicates with the IC card and reads the stored identification information. Therefore, the carrier can determine whether the IC card is valid or not by comparing the identification information read from the IC card with the preset information without recognizing the IC card.

[0010] Further, the sensor detects a person located in the vicinity of the reading device. In response to this, an image of the person is taken by a camera, and the data of the taken image is transmitted via a communication path and stored in a storage device. Is stored as a database. The photographed image data includes a photographed image in a state where valid identification information cannot be read by the reading device. Further, the accumulated image database stores the photographing time information in association with each image data. ing. Therefore, necessary image information can be easily and quickly retrieved from the database using the photographing time information as a key. Further, since the database is included in the database, other information processing apparatuses (for example, a security center, etc.) can be obtained via a communication path. (A monitor using a computer).

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An IC card management system according to the present invention will be specifically described with reference to one embodiment shown in the drawings. As shown in FIG. 1, the IC card management system of this embodiment is applied to authentication management for unlocking an electric lock 2a of a door 2 provided in a passage 1. For this reason, as shown in FIG. 2 showing the overall configuration of the system, the IC card management system of the present embodiment includes an IC card 10 carried by a person who is authenticated.
A reader / writer device 11 as a reading device, an authentication device 12 for determining whether or not it is valid based on identification information, a sensor 13 for detecting a person, a monitoring camera 14 for capturing an image,
In addition to a database server 15 for storing photographed image data as a database and a communication path 16 for transmitting photographed image data, a personal computer (PC) 17 having a monitor installed at a security center is also provided.

The reader / writer device 11 has a configuration as shown in FIG. 3 and reads and writes various information wirelessly with the IC card 10 and also controls the IC card 10.
It has a function of supplying operating power to the C card 10.
Write information and inquiry information to the IC card 10 are modulated by a modulator 22 via a controller (CPU) 21, further amplified by an amplifier 23, and
4 and transmitted from the antenna 25 to the IC card 10. Further, the reader / writer device 11 transmits an electromagnetic wave from the antenna 25, and thereby supplies operating power to the IC card 10. On the other hand, the information transmitted from the IC card 10 is received by the antenna 25, and is demodulated by the demodulator 26 via the circulator 24, and is demodulated by the controller 2.
Enter 1 Here, information to be transmitted to the IC card and I
Information received from the C card is transmitted to the communication interface 27.
The information is transmitted to the communication path 16 via the communication path 16 and another device connected to the communication path 16 writes information on the IC card 10 and processes information read from the IC card 10. The memory 28 shown in FIG. 3 stores information used by the controller 21 and provides a work area for information processing.

The IC card 10 has a configuration as shown in FIG. 4, and is supplied with operating power within a range of, for example, 2 m or less by electromagnetic coupling with the reader / writer device 11 and responds to inquiry information. The stored information is transmitted. The IC card 10 receives an electromagnetic wave transmitted from the reader / writer device 11 from the antenna 31 and converts an induced AC voltage into a DC current by a rectifier circuit to be used as an operation power source. As a result, the interrogation information received from the reader / writer device 11 by the antenna 31 is demodulated by the modem 32, and the controller (CPU)
33, and the controller 33 responds accordingly to the memory (RA
M) is read out, modulated by the modem 32 and transmitted from the antenna 31 to the reader / writer device 11.

The communication path 16 is configured as a LAN in this embodiment, and includes a reader / writer device 11, an authentication device 12, a sensor 13, a monitoring camera 14, a database server 15,
The PC 17 having the monitor and the electric lock 2a of the door 2 are connected to each other via a communication path to transmit various information and commands. In this example, the authentication device 12 is constituted by a computer that plays a central role in management control, and stores information (identification information for unlocking the electronic lock 2a in this example) set for performing authentication. A function of comparing the identification information read from the built-in memory and the IC card 10 with information stored in the built-in memory to determine whether or not it is valid; a function of unlocking the electric lock 2a when determined to be valid; detection from the sensor 13 It has a function of operating the monitoring camera 14 in response to the notification.

The sensor 13 is constituted by a known sensor such as an infrared sensor, and detects that a person has moved to the vicinity of the reader / writer device 11 (the reading range of the above-mentioned IC card), and notifies this detection. Authentication device 12
Send to The surveillance camera 14 according to the present embodiment is configured by a video camera installed in the direction of the reader / writer device 11, and receives an operation command from the authentication device 12 to convert an image around the reader / writer device 11 into a predetermined image. Photographing is performed for a time (for example, 30 seconds), and the photographed image data is transmitted to the communication path 16. Here, the surveillance camera 14 of the present example has a built-in timer, records date and time information at that time in an image taken as a time plus VTR image, and adds shooting time information to the shot image data for communication. It transmits to the road 16. In this example, the surveillance camera 14 is a video camera, but a digital still camera capable of continuous shooting may be used.

The database server 15 is composed of a computer having a large-capacity memory such as a hard disk. The database server 15 receives image data shot by a monitoring camera from a communication path 16 and associates the image data with shooting time information. And store it in memory as a database. In this example, as shown in FIG. 5, each image data is added to the respective image data and stored in the memory. However, the image data is collectively stored as an index table, and each image data is associated with each image data. Alternatively, the image data to be stored may be stored in a memory in association with a pointer by using a pointer.
That is, in the present invention, the storage format is not particularly limited as long as the image data stored in the memory can be searched using the shooting time information as a key. In this example, the photographing time information added by the monitoring camera 14 is used. However, the time at which the database server 15 receives the image data from the communication path 16 may be used by imitating the photographing time. Then, the function of the monitoring camera 14 can be reduced.

Next, the operation of the IC card management system having the above configuration will be described. First, identification information (for example, name, employee number, etc.) of the carrier is stored in the memory 34 of the IC card 10 in advance. When such an IC card 10 is carried by each person (and may be lowered on the chest or the like) and approaches the reader / writer device 11, the reader / writer device 11 and the IC card 10 are electromagnetically coupled. The identification information stored in the memory 34 is read by the reader / writer device 11, the identification information is transmitted to the authentication device 12, and the fact that the person is in the vicinity of the reader / writer device 11 is detected by the sensor 13. Is detected.
The authentication device 12 determines whether the read identification information is valid (i.e., whether to permit unlocking), and if so, unlocks the electric lock 2a and opens the door 2 by the person. Allow that.

On the other hand, when the result of the determination is not valid, the authentication device 12 activates the surveillance camera 14 without unlocking the electric lock 2a and outputs an image near the reader / writer device 11 (ie, the vicinity of the reader / writer device 11). (The image of the person located in the area). The photographed image data is stored in the database server 15 via the communication path 16 and is stored in a format that can be searched using the photographing time information as a key. Therefore, when a person who is not determined to be legitimate by the authentication process attempts to open the door 2, the image of the person is stored in the database 15 together with the photographing time, and when something becomes necessary later, the PC 17 of the security center is used. Thus, it is possible to easily and quickly search the database 15 and display the corresponding image on the monitor screen for confirmation.

Here, in the above example, even if a person is detected by the sensor 13, the surveillance camera 14 is operated to take an image only when the validity cannot be determined from the identification information. The image of a person with a high score can be taken as a database, and unnecessary operation of the surveillance camera 14 can be reduced, and the capacity of the database memory can be used effectively. In the present invention,
Regardless of the result of the validity determination, the monitoring camera 14 may be operated to capture an image in response to the detection by the sensor 13, and in this case, even if the person approaches the door 2, the image of the person may be obtained. Can be stored, and many images that may be suspicious individuals can be stored and stored. Which of these settings is to be used depends on practical needs.

The PC 17 installed at the security center may also receive the photographed image data sent to the database server 15 through the communication path 16 so that the image being photographed can be monitored by a monitor. The function performed by the device 12 may be performed by the PC 17. In the above example, the IC card 10 which does not have a power supply is used, but an IC card which has a built-in battery and operates on its own power supply may be used.

[0021]

As described above, according to the present invention,
By integrating the improved surveillance camera system with a non-contact IC card system, a carrier can be authenticated without recognizing the IC card, and the image data of the person to be authenticated is stored in a database. The necessary images can be easily and quickly searched using the accumulated time information as a key, and further, the image data stored in the database can be easily used by other information processing devices via a communication path. Can be realized, which is not possible with conventional systems, such as enabling
