DETAILED DESCRIPTION Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art may easily implement the present invention.

1 is a diagram illustrating a system configuration for maintaining security when an RFID tag is lost according to an exemplary embodiment of the present invention.

The system for maintaining security when RFID tag is lost includes access control module (100, 200, 300) and access management module (100, 200, 300) installed in each entrance door or its vicinity of a multi-unit apartment complex. Generation management server 400 to manage the.

Access control module (100, 200, 300) installed in each access entrance or the surrounding area reads the RFID tag located within a predetermined distance, and transfers the read RFID tag information and the access management module identifier to the household management server (400). do.

In addition, the access management module (100, 200, 300) opens the door when receiving the access approval message according to the RFID tag information transmitted from the household management server 400, access according to the RFID tag information delivered from the household management server (400) If a failure message is received, the door is kept closed.

The household management server 400 includes resident information in each building, and receives RFID tag information and an access management module identifier from the access management modules 100, 200, and 300 installed in each building.

When the household management server 400 receives the RFID tag information and the access management module identifier from any one of the access control modules 100, 200, and 300 installed in each building, the household information corresponding to the RFID tag information using the resident information. And search the information corresponding to the access control module identifier.

In this case, the resident information includes the name of the resident, the town and lake where the resident lives, the access control module identifier installed in the resident residence, the floor information to which the resident moves, and the RFID tag information attached to the access card possessed by the resident.

The generation management server 400 transmits an access approval message to the access management module that receives the RFID tag information when the information corresponding to the received RFID tag information and the corresponding information corresponding to the received access management module identifier match.

However, if the household information corresponding to the received RFID tag information and the corresponding information corresponding to the received access management module identifier does not match, the household management server 400 transmits an access failure message to the access management module receiving the RFID tag information. At the same time, record the cumulative number of blocking times of the RFID tag.

The generation management server 400 determines whether the cumulative number of blocking times of the corresponding RFID tag has exceeded the reference number within the reference time, and if so, performs the setting of disabling the access card with the corresponding RFID tag.

Here, the reference frequency refers to the cumulative number of blocking times of the corresponding RFID tag that is blocked by accessing the corresponding RFID tag information from the multiple access control modules until the disabled setting for the access tag with the RFID tag is set. Time refers to a time interval for calculating the cumulative number of times that the RFID tag information is transferred from different access management modules to block access. That is, if the reference time is set to 10 minutes and the number of times of 3 times to set the access card with the RFID tag attached, the number of times that the same RFID tag information is delivered from the multiple access control modules is blocked within 10 minutes. In the case of 3 times, the disabled setting of access card with RFID tag is performed.

For example, the household management server 400 receives the RFID tag information and the access management module identifier of a resident living in building D from the access management module 100 of building A, and manages the access information D and access corresponding to the RFID tag information. The information A corresponding to the module identifier is compared. The generation management server 400 determines that the information corresponding to the RFID tag information and the information corresponding to the access management module identifier do not coincide with each other, and blocks access to the corresponding RFID tag information. Record the entry block.

Afterwards, the generation management server 400 receives the RFID tag information and the access management module identifier of the inhabitants living in the D building from the access management module 200 of the building B, and assigns the same to the information D and the access management module identifier corresponding to the RFID tag information. The corresponding copper information B is compared, and it is determined that the copper information corresponding to the RFID tag information does not match the copper information corresponding to the access control module identifier.

In addition, the generation management server 400 blocks access to the corresponding RFID tag information and records cumulative blocking times for the RFID tag, that is, access is blocked twice.

Since the household management server 400 receives the RFID tag information and the access management module identifier of the residents living in the building D from the access control module 300 of building C, the information management C and the access management module identifier corresponding to the RFID tag information. It determines that the corresponding information D does not match, blocks access to the corresponding RFID tag information, and records the cumulative number of blocking times for the RFID tag.

If the number of cumulative blocking times for performing suspension setting for the access tag with the RFID tag is set to three times within 10 minutes of the reference time, the generation management server 400 accumulates the cumulative blocking number of the corresponding RFID tag for the third time. When the RFID tag information transmission time is measured until it is determined, and if it is determined that there are three times of access blocking for the corresponding RFID tag within 10 minutes, the setting of disabling the access card with the corresponding RFID tag is performed.

The household management server 400 notifies each consent management room of the access tag information with the RFID tag on which the suspension setting is performed, and rings an emergency bell to inform that someone is attempting to enter the lost access card. .

2 is a flowchart illustrating a process of maintaining security when an RFID tag is lost according to an embodiment of the present invention.

Referring to FIG. 2, in step S210, the generation management server 400 receives the RFID tag information and the access management module identifier from the access management module 100 of Building A and the information corresponding to the RFID tag information received in step S220. And whether the information corresponding to the access control module identifier is identical.

At this time, the household management server 400, if the copper information corresponding to the RFID tag information received in step S220 and the copper information corresponding to the access management module identifier is identical, in step S240 access control module 100 of the access approval module A If the information corresponding to the RFID tag information and the information corresponding to the access management module identifier do not match in step S220, the process proceeds to step S230 and transmits an access failure message to the access management module 100 of Building A. .

And the generation management server 400 records the cumulative blocking times for the RFID tag access block in step S250.

At this time, if the cumulative blocking times for the RFID tag access blocking recorded in step S250 or more than the reference number within the reference time, the generation management server 400 performs the stop setting of the access card with the corresponding RFID tag in step S270 and each Inform the consent office of the access card with the corresponding RFID tag.

In this way, even if the RFID tag attached to the lost access card can be detected that someone is attempting to enter the agreement by using it can prevent crime and maintain strict security.
