Description of the Related Art Conventionally, barcodes are attached to articles sold at a store for identifying the articles (in addition to information on producers, distribution channels, article materials, handling precautions, etc.). From this bar code, information relating to the item (for example, item number, price, etc.) can be read by a bar code reader of a POS (Point Of Sales) terminal and used at the time of accounting.

  In recent years, distribution of articles has been managed by adding RFID (IC tags) to articles. The RFID stores information for identifying the article (for example, detailed article information (RFID information) such as the article number, color, and size of the article). RFID is a wireless information recognition method that can be read and written without contact, or read-only, and can be used repeatedly. RFID has a minimum storage capacity of identification content from 128 bits compared to a widely used barcode, and a large one is several Kbit or more, and is being used as an identifier for identifying an article.

In the process of step S <b> 46, the information transmission processing unit 42 provides the RFID concealment information and user information to the information management server 20. In step S47, the RFID information reception processing unit 44 determines whether authentication by the information management server 20 is successful, that is, whether RFID information is received from the information management server 20. If the authentication is not successful in the process of step S47, the process from step S40 is performed. If the authentication is successful in step S47, the RFID information write-back processing unit 43 writes the received RFID information in the RFID in step S48. In the process of step S49, the article information display processing unit 46 displays the article information acquired from the information management server 20 on the display based on the RFID information.

  In this way, the user terminal 40 provides the RFID concealment information to the information management server 20, receives the RFID information according to the authentication result, writes it back to the RFID, and displays the article information based on the RFID information. Thus, leakage of RFID information related to the article can be prevented, and the user can browse the detailed information of the purchased article.

  Next, processing executed by the user terminal 40 in the case of read-only RFID will be described. FIG. 7 is a flowchart showing processing at the user terminal in the case of read-only RFID. In FIG. 7, in the case of read-only RFID, since the RFID information is invalid, the URL that is the location information of the Web page for browsing the detailed information of the article from the information management server 20 to the user terminal 40 is You will be notified by email. First, in the process of step S50, the URL notified by e-mail from the user terminal 40 is clicked. In step S51, the information management server 20 makes an inquiry to the user terminal 40. In the process of step S <b> 52, the information transmission processing unit 42 transmits RFID information and user information to the information management server 20.

  In step S53, it is determined whether authentication by the information management server 20 has succeeded, that is, whether the information management server 20 can provide a web page to the user terminal 40. If the authentication by the information management server 20 is not successful in the process of step S53, the process ends. If the authentication by the information management server 20 is successful in the process of step S53, the article information display processing unit 46 displays the Web page provided from the information management server 20 in the process of step S54. In step S55, it is determined whether there is an article for which the user wants to know detailed information. If there is no article for which detailed information is desired in the process of step S55, the process at the user terminal 40 is terminated.

  If there is an article for which detailed information is desired in the process of step S55, the article information to be referred to on the Web page is clicked by the user terminal 40 in the process of step S56. In the process of step S57, the article information display processing unit 46 displays the detailed information of the article provided from the information management server 20.

  The web page is created in advance by the web page creation processing unit 26 of the information management server 20 based on the article information from the article information server 60 and the RFID information stored in the RFID save information DB 200. And

  As described above, the user terminal 40 displays the Web page of the URL provided from the information management server 20, provides the RFID concealment information to the information management server 20, and displays the detailed information of the article according to the authentication result. Thus, leakage of RFID information related to the article can be prevented, and the user can browse the detailed information of the purchased article.

  Next, the RFID information saving / restoring process in the case of a readable / writable RFID will be described in detail. FIG. 8 is a flowchart showing RFID information saving / restoring processing in the case of RFID that can be read and written. The article information server 60 shown in FIG. 8 stores a company information DB 61 in which company information about articles is stored, an article information DB 63 in which article information is stored, and server authentication information for authenticating the information management server 20. It is assumed that the server authentication information DB 64 is provided. In FIG. 8, when purchasing an article to which a user can read and write RFID 5, a record 100 that is RFID information stored in RFID 5 by RFID reader / writer 50 installed at store terminal 30 (register). Is read (step S1). Note that the record 100 stores an organization ID, a company ID, a product ID, and a serial number associated with the detailed information of the article.

  The RFID information record 100 read by the RFID reader / writer 50 is provided to the article information server 60, and the detailed information of the article is searched (step S2). At the same time, the record 100 read by the RFID reader / writer 50 and the user information input from the store terminal 30 are provided to the information management server 20, and the record 100 is added with an identification ID for identifying the RFID. 101 is registered in the RFID save information DB 200. Further, the information management server 20 creates a record 102 obtained by converting RFID information into RFID concealment information based on user information, and registers the record 102 in the user information DB 210. The created RFID concealment information record 102 is transmitted to the store terminal 30, and the RFID concealment information is written into the RFID 5 by the RFID reader / writer 50 (step S3). The record 102 stores an organization ID, a company ID, an identification ID, and user authentication information for authenticating the user in order to match the system with the record 100.

  The user takes the RFID rewritten with the RFID concealment information home (step S4). When it is desired to browse the detailed information of the article, the RFID concealment information record 102 is read from the RFID 5 by the RFID reader / writer 51 connected to the user terminal 40 (step S5).

  The RFID concealment information record 102 read by the RFID reader / writer 51 and the user information input from the user terminal 40 are provided to the article information server 60, and the detailed information of the article is retrieved (step S6). The article information server 60 refers to the server authentication information DB 64 based on the provided record 102, and distributes the record 102 and user information to the information management server 20 (step S7).

  The information management server 20 authenticates the user based on the user authentication information and user information stored in the record 102 (step S8). When the authentication is successful, the information management server 20 extracts the corresponding RFID information from the RFID save information DB 200 and provides it to the user terminal 40. The RFID information is written to the RFID 5 by the RFID reader / writer 51 of the user terminal 40, and the information is restored (step S9). The user terminal 40 acquires detailed information on the article based on the restored RFID information and displays it on the display.

  In this way, the RFID information related to the article is saved in the information management server 20 for each user, the RFID information is converted into the RFID concealment information, and the RFID concealment information is restored to the RFID information according to the user authentication result. Accordingly, it is possible to effectively use RFID information that enables browsing of detailed information of an article, to prevent leakage of RFID information related to the article, and to contribute to the spread of RFID.

  Next, a process for saving a plurality of RFID information will be described in detail. FIG. 9 is a flowchart showing a process for saving a plurality of RFID information. In FIG. 9, when purchasing a plurality of articles (articles A and B) to which the user can read and write RFID 5, the articles A and B are used by the RFID reader / writer 50 installed at the store terminal 30 (registry). Records 110 and 111 which are RFID information stored in the RFID 5 are read (step S1).

  The RFID information records 110 and 111 read by the RFID reader / writer 50 are grouped (group X), for example, for each store or for each cash register, and are provided to the article information server 60 to manage detailed information on articles. Is done. At the same time, user information input from the store terminal 30 such as a telephone number, e-mail, authentication code, etc. is provided to the article management server 60 (step S2).

  Further, records 110 and 111 are transmitted from the article information management server 60 to the information management server 20, and records 112 and 113 obtained by adding an identification ID for identifying the RFID to the records 110 and 111 are set in the RFID save information DB 200. (Step S3). Further, the information management server 20 creates records 114 and 115, which are RFID concealment information having user authentication information obtained by encrypting the user information from the article information server 60, and registers it in the user information DB 210 (step S4). ). As examples of identification IDs stored in the records 114 and 115, as shown in the record 120, a group identification number (group X), a serial number, and the like may be stored. Further, as an example of the user authentication information stored in the records 114 and 115, as shown in the record 121, a user telephone number, a user authentication code, and the like may be stored.

  The created RFID concealment information records 114 and 115 are transmitted to the store terminal 30, and the RFID reader / writer 50 rewrites the RFID information of the RFID5 into the RFID concealment information records 114 and 115 (step S5).

  In this way, by storing the RFID information of a plurality of articles in the information management server 20 and converting the RFID information into RFID concealment information, the RFID information regarding the plurality of articles is efficiently managed and the leakage of the RFID information is prevented. can do.

  Next, RFID information saving / restoring processing in the case of read-only RFID will be described in detail. FIG. 10 is a flowchart showing RFID information saving / restoring processing in the case of read-only RFID. In FIG. 10, when a user purchases an article with read-only RFID 5 added, a record 100 that is RFID information stored in RFID 5 is read by an RFID reader / writer 50 installed at a store terminal 30 (a cash register). (Step S1).

  The RFID information record 100 read by the RFID reader / writer 50 is provided to the article information server 60, and the detailed information of the article is searched (step S2). At the same time, the record 100 read by the RFID reader / writer 50 and the user information input from the store terminal 30 are provided to the information management server 20, and the record 100 is added with an identification ID for identifying the RFID. 101 is registered in the RFID save information DB 200. Further, the information management server 20 creates a record 119 obtained by converting the RFID information into concealment information (RFID information and user information) based on the user information, and registers the record 119 in the user information DB 210. At the same time, the RFID reader / writer 50 of the store terminal 30 converts the RFID 5 record 100 into a record 116 indicating invalid information that cannot be read (step S3). In the record 116 indicating the invalid information, all zeros, all blanks, all Fs, all nulls, etc. are written only once.

  From the store terminal 30 (or the information management server 20), the user terminal 40 (or the mobile phone 6) notifies the user terminal 40 (or the mobile phone 6) of the URL, which is the location information of the Web page where the detailed information of the article can be viewed (step) S4). The user refers to the Web page from the URL notified to the user terminal 40 (step S5). In response to an inquiry from the information management server 20 that manages the Web page, RFID information and user information are received from the user terminal 40 and authentication is performed (step S6). If the authentication is successful, the information management server 20 provides the RFID information record 101 of the article purchased by the user to the article information server 60, and the detailed information of the article is retrieved (step S7). In the user terminal 40, detailed information on the article is displayed on the Web page.

  As described above, the RFID information related to the article is saved in the information management server 20 for each user, the RFID information is invalidated, and the RFID information is provided to the user according to the authentication result of the user. While preventing the leakage of the RFID information, the user can browse the detailed information of the article.

  Next, restoration processing of RFID information in the case of read-only RFID will be described in detail. FIG. 11 is a flowchart showing a process of restoring RFID information in the case of read-only RFID. In FIG. 11, when the user wants to view detailed information of a plurality of articles taken home, the RFID 117 records 117 and 118 cannot be read. Therefore, the user terminal 40 connects to the Web page, and the information management server 20 authenticates the user who purchased the article (step S1).

  If the authentication is successful, the information management server 20 corresponds to the identification ID of the records 125 and 126 of the concealment information (RFID information and user information) stored in the user information DB 210 and the RFID stored in the RFID save information DB 200. Information records 110 and 111 are extracted. The extracted RFID information records 110 and 111 are provided to the article information server 60, and the detailed information of the article is searched (step S2). The article information server 60 transmits detailed information (article information) of the article extracted based on the provided records 125 and 126 to the user terminal 40 or the mobile phone 6 (step S3).

  Thus, by providing the user terminal 40 with the detailed information of the article according to the user authentication result, it is possible to prevent the leakage of RFID information related to the article and the user can browse the detailed information of the article. it can.
