Apparatus and Method for managing Product Distribution using Security Tag

The present invention relates to an article distribution management apparatus and method, and more particularly to an article distribution management apparatus and method using a security tag.

The present invention is derived from the research conducted as part of the IT growth engine technology development project of the Ministry of Knowledge Economy and the Ministry of Information and Telecommunication Research and Development. [Task management number: 2005-S-106-04, Task name: Sensor tag for RFID / USN and Sensor node technology development].

In general, it is possible to easily manage the distribution of goods using the RFID tag.

Hereinafter, the article distribution management method using an RFID tag is demonstrated.

1 is a diagram illustrating a process of writing article information on a tag, and FIG. 2 is a diagram illustrating a process of reading article information included in a tag.

Referring to FIG. 1, when an item registration is requested, the RFID manager 101 allocates a unique item identifier (UII) corresponding to a serial number of an item to the item, and transmits the allocated UII to the passive reader 105. In addition, the RFID manager 101 transmits the allocated UII and article information on the article to the article data server 103.

The passive reader 105 may be a writing reader and rides the received UII on the RFID tag 107.

Thereafter, the RFID manager 101 attaches the RFID tag 107 on which the UII is recorded to the article.

Referring to FIG. 2, the article distribution management system includes a passive reader 201, an operation data store (ODS) proxy server 203, an article data server 205, and an RFID tag 207.

The passive reader 201 may be a reading reader and, when the article is received, reads the UII from the RFID tag 207 attached to the article.

When the ODS Proxy server 203 receives an item data server address request for managing item information of an item corresponding to the UII from the passive reader 201, the ODS proxy server 203 transmits the address of the item data server to the passive reader 201.

When the article data server 205 receives the article information request of the article corresponding to the UII from the passive reader 201, the article data server 205 transfers the article information to the passive reader 201.

As a result, the passive reader 201 can confirm the information on the article, based on the article information received from the article data server 205.

Such a product distribution management system has a problem in that when the function of securely authenticating the contents of the RFID tag is not provided, the UII of the RFID tag may be duplicated and attached to an unauthorized item during the distribution process. That is, the conventional passive RFID tag used in the article management has a security mechanism function using an access password, but there is a problem that the contents of the access password can be easily analyzed and the RFID tag can be duplicated.

Therefore, there is a need for an article distribution management apparatus and method that is impossible to replicate so that articles can be safely managed.

The problem to be solved by the present invention is to provide an article distribution management apparatus and method that can safely and easily manage the article by using a security reader to determine whether the RFID tag is duplicated using the security key.

An article distribution management apparatus according to an embodiment of the present invention for solving the above problems is a reading unit for reading the security key of the article from the security tag attached to the article, the first authentication information encrypted using the security key and And a receiving unit for receiving second authentication information from a security server and the security tag, and a determination unit for determining whether to copy the security tag using the first authentication information and the second authentication information.

An article distribution management method according to an embodiment of the present invention for solving the above problems is the step of reading the security key of the article from the security tag attached to the article, and transmitting the read security key to the security server, Receiving first authentication information encrypted using the transferred security key from the security server, receiving second authentication information encrypted using the security key from the security tag, and the first authentication Determining whether the security tag is duplicated using information and the second authentication information.

The article distribution management apparatus according to the embodiment of the present invention may determine whether the article is tampered with by using a security reader that determines whether or not the RFID tag is copied using the security key. In addition, by preventing the tampering of the tags attached to the article, the article can be safely and easily managed.

Hereinafter, with reference to the accompanying drawings will be described in detail with respect to the goods distribution management system according to an embodiment of the present invention.

FIG. 3 is a diagram illustrating a process of writing article information on a security tag in an article distribution management system using a security tag, and FIG. 4 is a article included in a security tag in an article distribution management system using a security tag. A diagram illustrating a process of reading information.

Referring to FIG. 3, when an item registration is requested, the RFID manager 301 allocates a UII to the item and transfers the allocated UII to the security reader 305. In addition, the RFID manager 301 transmits the allocated UII and article information on the article to the article data server 303.

The security server 307 tables and manages the security keys for each item of the UII, and provides the security keys to the security reader 305.

The security reader 305 may be a riding reader, and records the security key 309 corresponding to the UII and the UII received from the RFID manager 301 and the security server 307, respectively. Here, the security tag 309 means an RFID tag in which a security key corresponding to the UII and the UII is recorded.

Thereafter, the RFID manager 301 attaches the security tag 309 in which the UII and the security key are recorded to the article.

Referring to FIG. 4, the article distribution management system includes a security reader 401, an ODS Proxy server 403, an article data server 405, a security server 407, and a security tag 409.

The security reader 401 may be a reading reader, and when the article is received, the UII and the security key are read from the security tag 409 attached to the article. Here, the security tag 409 is pre-recorded the UII and the security key corresponding to the UII. In addition, the security reader 401 transfers the server authentication information received from the security server 407 to the security tag 409.

When the ODS Proxy server 403 receives an item data server address request for managing item information of an item corresponding to the UII from the security reader 401, the ODS proxy server 403 transmits the address of the item data server to the security reader 401.

The article data server 405 manages and stores article information about the article by serial number of the article. When the article data server 405 receives the article information request of the article corresponding to the UII from the security reader 401, the article data server 405 transmits the article information to the security reader 401. In this case, the article data server 405 may deliver the address of the security server as well as the article information of the article corresponding to the UII.

When the security server 407 receives the security key from the security reader 401, the security server 407 transmits the first authentication information, that is, the server authentication information, encrypted using the security key, to the security reader 401.

When the security tag 409 receives the encrypted first authentication information from the security reader 401, the security tag 409 decrypts the first authentication information by using the security key recorded in the security tag 409. In addition, the security tag 409 transmits the second authentication information, that is, the tag authentication information, which is re-encrypted with the first authentication information decrypted using the security key, to the security reader 401.

As a result, the security reader 401 may determine whether the security tag is duplicated using the first authentication information and the second authentication information received from the security server 407 and the security tag 409, respectively. That is, when the first authentication information and the second authentication information are the same, the security reader 401 may determine that the security tag 409 attached to the article is not duplicated. However, when the first authentication information and the second authentication information are not the same, the security reader 401 may determine that the security tag 409 attached to the article is duplicated.

In addition, when it is determined that the security tag is not duplicated, the security reader 401 may check the information on the article based on the article information received from the article data server 405.

In the article distribution management system according to an embodiment of the present invention, the security tag stores only the UII, and the article data server may store related information such as the type, grade, weight, origin, and distribution route of the article. Of course, the security tag may store the item information of the UII and the item corresponding to the UII, but the data is generally stored in the item data server due to size or power.

Therefore, the article distribution management system according to the embodiment of the present invention can block the duplication of the tag by using a security reader that determines whether or not the duplication of the security tag using the security key. Accordingly, the article can be safely and easily managed.

Subsequently, the security reader determines whether the security tag is duplicated using the first authentication information and the second authentication information (S607).

In detail, when the first authentication information and the second authentication information are the same, the security reader may determine that the security tag attached to the article is not copied (S609). However, when the first authentication information and the second authentication information are not the same, the security reader may determine that the security tag attached to the article is duplicated (S611).

7 to 9 are diagrams for explaining the distribution network structure for explaining the distribution structure and goods distribution management using the security reader according to the present invention.

7 to 9, the goods distribution management system may include a data server and a security server for each distribution step.

Each data server of the distribution stage may include an agricultural branch data server, a slaughterhouse data server, a processing plant data server, and a sales data server. Each data server stores item information and UII for goods by the RFID manager in each distribution stage.

For example, when slaughtered at a slaughterhouse, the old tag may be discarded and a new tag may be attached to the slaughtered cow. In this case, when the slaughtered cattle are Korean cattle, a security tag may be attached, and the UII and the security key may be recorded on the security tag. On the other hand, when the slaughtered cow is a cow, a general tag may be attached.

The information recorded in the security tag is not limited to the UII and the security key, and history information about the slaughtered cow may be further recorded. Here, the history information may include, for example, information such as a ranch, a slaughterhouse, a breed, a part, a grade, a weight, and a transport temperature.

History information and the UII of the slaughtered cattle may be stored in the slaughterhouse data server.

In addition, when the beef is processed, the previous tag may be discarded and a new tag with the UII and security key recorded on the processed beef may be attached. In this case, when the processed cow is a Korean cattle, a security tag may be attached.

History information and UII of the processed cattle may be stored in the processing plant data server.

As a result, the cattle are passed to farmers, slaughterhouses, and meat processing plants and finally handed over to the seller. At this time, in each distribution step, by confirming the authentication of the tag attached to the article through the security server, it is possible to ensure the stability of the article.

Therefore, by applying a non-replicable security tag according to an embodiment of the present invention to the cattle, the situation in which the fake Korean cattle (for example, cows or imported meat) are slaughtered and distributed as genuine Korean cattle can be blocked.
