Description

How to prevent theft of products in RFID system {Method for preventing burglary of goods in RFID system}

The present invention relates to a method for preventing theft of a product in an RFID system.

In general, an RFID system is a type of automatic recognition technology, and includes a reader capable of reading or writing data or information, and an RFID tag having a microchip that reads or records data or information according to a signal transmitted from the reader. And a server device for identifying and processing software, data or information used in these devices.

RFID tags are classified into passive and active according to the use of batteries.

First, the passive type tag consists of an antenna coil and an IC chip. When the tag enters the electromagnetic field emitted from the reader, an AC voltage is applied to the antenna coil of the tag, and the voltage is applied to the DC voltage. It is rectified to use as a power source for IC chip. The IC chip operates by applying a constant voltage to transmit data to the reader. This is called backscattering.

In addition, the active type tag has a battery inside and transmits an RF signal to the outside according to a pre-stored time interval while the battery is maintained. Therefore, although the data transmission and reception is possible far longer than the passive tag, the price is expensive, and the service life is limited according to the life of the battery.

The reader supplies RF energy to the passive tag and activates it to receive data or information from the tag. In addition, the reader includes a part for transmitting / receiving an RF signal and performing data decoding, and performs serial communication (RS-232), USB, Ethernet, and the like with the server.

On the other hand, in public buildings, such as libraries, which many people use, there is a risk of belongings being stolen. In particular, if the owner possesses advanced electronic equipment such as a notebook PC or a PDA, the risk of theft increases. Therefore, the owner is inconvenient to carry the belongings because they are anxious to leave the belongings. In addition, even if the belongings are stolen, there is a problem that it is difficult to notice easily. Conventionally, in order to prevent theft problem in public places, security systems such as CCTV installation and security company employment have been prepared, but it is not enough to prevent theft of personal belongings.

The present invention provides a method for easily preventing theft of a product possessed by an individual in a public place where an RFID system is installed.

The present invention provides a method for preventing theft of a product in an RFID system including a reader that reads RFID tag information at an entrance of a building, the product RFID tag information embedded in a product and a personal RFID tag embedded in a personal identification card. The first step of reading information, the second step of registering the registered product RFID tag information and the personal RFID tag information in association, and if the associated product RFID tag information is detected, the personal RFID associated with the RFID tag information And a third step of checking whether tag information is detected and a fourth step of outputting a warning sound if the personal RFID tag information is not detected.

According to the present invention, it is possible to easily detect whether a product is stolen by an individual using an RFID system and to prevent theft in advance.

In addition, there is an advantage that can be noticed immediately when theft occurs.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. First of all, in adding reference numerals to the components of each drawing, it should be noted that the same reference numerals have the same reference numerals as much as possible even if displayed on different drawings. In describing the present invention, when it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

1 is a view schematically showing a product theft prevention system using RFID according to an embodiment of the present invention.

In FIG. 1, an RFID system including a reader 200 located at an entrance of a public building such as a library to read RFID tag information is illustrated. In the present invention, the RFID system includes an RFID tag, an RFID reader 200, and a server 300.

In FIG. 1, the RFID tag is embedded in the notebook PC 11 and the PDA 13 possessed by the user, and also embedded in the personal identification card 21 of the user. In FIG. 1, the product possessed by the user is an electronic product such as a notebook PC 11 or a PDA 13, but this is only an example, and is not limited to the electronic product, but may be implemented by embedding an RFID tag in various products. have. Meanwhile, in one embodiment of the present invention, an RFID tag may be an active tag or a passive tag.

The RFID reader 200 detects an RFID tag and reads information of the RFID tag. In the embodiment of FIG. 1, the reader 200 reads RFID tag information embedded in the notebook PC 11, the PDA 13, and the personal identification card 21.

The server 300 stores or processes the RFID tag information read by the RFID reader 200.

A detailed description of how to prevent the product from being stolen in the RFID system will be described with the flowchart of FIG. 2.

2 is a flowchart illustrating a method for preventing product theft in an RFID system according to an embodiment of the present invention.

The product RFID tag information embedded in the product and the personal RFID tag information embedded in the personal identification card are read (S201). For example, in the embodiment of FIG. 1, the reader 200 reads the product RFID tag information embedded in the notebook PC 11 and the PDA 13 and the personal RFID tag information embedded in the personal identification card 21. .

Registered product RFID tag information and personal RFID tag information are registered in association with each other (S203). For example, in the embodiment of FIG. 1, the server 300 registers product RFID tag information embedded in the notebook PC 11 and the PDA 13 in association with personal RFID tag information embedded in the personal identification card 21. do. That is, the server 300 registers the product RFID tag information embedded in the notebook PC 11 and the PDA 13 and the personal RFID tag information embedded in the personal identification card 21 in one group 100. will be.

Check whether the associated product RFID tag information is detected (S205).

When the linked product RFID tag information is detected, it is checked whether the personal RFID tag information linked to the product RFID tag information is detected (S207). For example, when the product RFID tag information embedded in the PDA 13 is detected in FIG. 1, it is checked whether the personal RFID tag information of the personal identification card 21 linked to the product RFID tag information is detected.

If the personal RFID tag information associated with the product RFID tag information is detected in step S207, no event occurs. This is because the true owner carries the product and passes through the doorway.

However, if the associated personal RFID tag information is not detected, a warning sound is output (S209). For example, when the personal RFID tag information of the personal identification card 21 linked to the product RFID tag information embedded in the PDA 13 is not detected, a warning sound is output. This means that a person who is not the true owner carries the product and passes through the doorway.

Outputting a warning sound in step S209 is only an embodiment, and according to the embodiment, various warning methods such as flashing a warning light or outputting a warning message may be implemented.

In one embodiment of the present invention, if the personal RFID tag information linked in step S209 is not detected for a predetermined time or more, a warning sound may be output. For example, if the personal RFID tag information of the personal identification card 21 linked to the product RFID tag information embedded in the PDA 13 is not detected within 5 seconds, a warning sound is output.

While the invention has been described using some preferred embodiments, these embodiments are illustrative and not restrictive. Those skilled in the art will appreciate that various changes and modifications can be made without departing from the spirit of the invention and the scope of the rights set forth in the appended claims.
