Best Mode for Carrying Out the Invention

An example of information acquisition by the information acquisition system 1 using the information authentication gateway 2 of this invention is demonstrated. Fig. 1 shows the overall conceptual diagram of the present invention, and Fig. 2 shows an example of the system configuration of the present invention.

The information acquisition system 1 of the present invention includes an information authentication gateway 2, a user terminal 4 connected to a reader 5 for reading an information code, and a server (each server 3) of each company. Have The user terminal 4 transmits the hierarchical position information read from the information code to the information authentication gateway 2, and transmits the information corresponding to the read information after the processing by the information authentication gateway 2 to each company server ( Acquire from 3).

The user terminal 4 is connected to a reader 5 that reads an information code. The reader 5 is a device for reading hierarchical position information included in an information code, such as information of a barcode, information of a two-dimensional code, information stored in an IC tag, and the user terminal 4 using the read hierarchical position information. To pass on.

The hierarchical positional information is a relational structure indicating paternity-property inheritance relations such as attributes of an object with an information code, which is constructed based on relationship-attribute information in basic semantic units based on object orientation, and connects relationship information. Can be expressed by. The basic semantic unit is divided into catalog information and attribute dictionary, as shown in FIG. 5. The catalog information is information that is the basis of the hierarchical positional information and is one element of information representing the attribute of the article. In addition, an attribute dictionary is the information which stores the detailed information of the attribute of catalog information. That is, the unique code assigned to the catalog information of the basic semantic unit is constituted by a parent classification indicating a unique code belonging to a higher level of the basic semantic unit, a name indicating the attribute, and an attribute. In the attribute dictionary indicating the attribute in the catalog information, the name and definition content of the attribute are associated with each other.

Fig. 5 shows a conceptual diagram of basic semantic units, and Fig. 6 shows a conceptual diagram of hierarchical position information constituted by the basic semantic units.

Each company server 3 is a server which makes it possible to search, modify and delete information corresponding to hierarchical positional information read from an information code, for example, for each company belonging to an industry organization. In addition, each company server 3 may be a server of only one company, and may be a server of multiple companies. In addition, one or more servers may be sufficient and a plurality may be sufficient as them.

In the present specification, the information corresponding to the hierarchical positional information is information about an attribute of an object to which an information code is attached or an object constituting the object (parts constituting the object, etc.), for example, tabular data (relays). Data formats such as national databases, spreadsheets, sequential files, etc.), tree-type data (tree-type data models), parametric data (three-dimensional CAD models, etc.), and spatial data (map data, etc.). This includes all data types that manage many different types of attributes, including multidimensional, multi-layer, and neuron types.

The information authentication gateway 2 has a hierarchical positional information acquiring means 6, an information comparing means 7, a metadata storing means 8, a ticket issuing means 9, and a metadata updating means 10.

The hierarchical positional information obtaining means 6 is means for receiving hierarchical positional information read from the information code by the reader 5 from the user terminal 4.

The information comparing means 7 compares whether the hierarchical positional information received by the hierarchical positional information obtaining means 6 is included in the metadata stored in the metadata storing means 8, and if included, the ticket The issuance means 9 is a means for transmitting a request for issuing a ticket information to be described later, and if not included, an error notification to the user terminal 4.

The metadata storage means 8 is a means for storing metadata, which is a basic semantic unit represented by a hierarchical structure, and is data representing the whole of the hierarchical structure. Therefore, the metadata storage means 8 stores information indicating which hierarchical position of each company server 3 stores information of basic semantic units corresponding to arbitrary hierarchical positional information.

When the ticket issuing means 9 receives a ticket issuance request from the information comparing means 7, the ticket information (for example, an alphanumeric symbol) necessary for the user terminal 4 to access each company server 3 is obtained. Information formed by columns) and transmitted to the user terminal 4 and a server storing information corresponding to hierarchical position information among the four server servers. In addition, when delivering ticket information to the user terminal 4, the information of the access destination, such as the address of the server used as an access destination, of each company server 3 is put together and conveyed. The information of the access destination can be determined based on the hierarchical positional information received from the user terminal 4 in the information comparing means 7. Therefore, in the information authentication gateway 2, the information of the access destination, such as the address of the server in each company server 3 contained in metadata, is memorize | stored.

In addition, when the information corresponding to the received hierarchical positional information is stored separately in a plurality of servers among the company servers 3, ticket information is transmitted to the respective servers, and from the user terminal 4 Allow access to each server. At this time, the ticket information may be common to each server or may be different.

The metadata update means 10 accesses the information storage means 14 of each company server 3 periodically or irregularly, detects the change of the hierarchical position information in each server, and detects the metadata storage means ( Means for updating metadata stored in step 8).

Each company server 3 has a ticket receiving means 11, a ticket comparing means 12, an information retrieving means 13, and an information storing means 14.

The ticket receiving means 11 of each company server 3 is a means for receiving the ticket information generated by the ticket issuing means 9 of the information authentication gateway 2.

The ticket comparing means 12 is a means for comparing the ticket information received by the ticket receiving means 11 with the ticket information received from the user terminal 4, and determining whether or not it is accessible (accessible). . When it is determined that it is accessible, the search by the information retrieval means 13 is permitted, and when it is determined that it is not accessible, an error notification is transmitted to the user terminal 4.

The information retrieval means 13 retrieves the information corresponding to the hierarchical position information from the information storage means 14 on the basis of the hierarchical positional information received from the user terminal 4, and the user terminal 4 as a result. It is a means of return.

The information storage means 14 associates and stores the basic semantic units of the object as a hierarchical structure, and is a means for storing the catalog information and the attribute dictionary in the basic semantic units. It is also stored in association with the hierarchical positional information. 6 is a conceptual diagram of a method of storing information having such a hierarchical structure.

Next, the processing process of the information authentication gateway 2 of this invention is demonstrated using the flowchart of FIG. 3, and the system block diagram of FIG.

In the information code attached to an object or the like, hierarchical positional information of the object is coded and stored. The user who wants to acquire attribute information or the like for the object reads the information code using the reader 5 provided in the user terminal 4, and reads the hierarchical position information contained therein (100).

The hierarchical positional information read by the reader 5 is transmitted to the information authentication gateway 2 by the user terminal 4, and received by the hierarchical positional information obtaining means 6 of the information authentication gateway 2 (S110). The received hierarchical position information is transmitted to the information comparing means 7, and the information comparing means 7 compares whether the received hierarchical position information is included in the metadata stored in the metadata storing means 8. (S120).

For example, when the received hierarchical position information is "A, X, XA" as shown in FIG. 6, it is checked whether the hierarchical position information is included as metadata, and when it is included (S130). ), The ticket issuing means 9 is delivered to the ticket issuing means 9.

The ticket issuing means 9 which has received the request for issuing the ticket from the information comparing means 7 generates the ticket information necessary for the user terminal 4 to access each of the company servers 3, and the respective company servers ( In step 3), the hierarchical positional information is transmitted to the stored server (S140). For example, when the information corresponding to hierarchical positional information "A, X, XA" exists in the server A of each company server 3, ticket information is transmitted to the server A.

In the above case, the information corresponding to the hierarchical positional information "A, X, XA" is stored in one server, but this may be stored separately in a plurality of servers. For example, the information of the hierarchical positional information "A, X" may be stored in the company A server, and the information in "XA" may be stored in the company B server. In that case, the ticket issuing means 9 delivers the ticket information to both the A company server and the B company server.

In addition, in the following description, when the information corresponding to hierarchical positional information is memorize | stored in the one server among each of the four servers 3 from the user terminal 4 (for example, hierarchical positional information "A, X, XA "is stored only in the company A server), but as described above, even when the information corresponding to the hierarchical position information is stored in a plurality of servers among the company servers 3, What is necessary is just to perform the process similar to the case of one server with respect to each server from the user terminal 4 simultaneously or with a predetermined timing. That is, when the information of the hierarchical positional information "A, X" is stored in the company A server and the information of "XA" is stored in the company B server, the processing from the user terminal 4 to the company A server (hierarchical positional information "A , The process of acquiring the information corresponding to "X", and the process (the process of acquiring the information corresponding to hierarchical positional information "XA") from the user terminal 4 to the company B server are similarly performed.

As a result of the comparison in the information comparison means 7 of S120, when the received hierarchical position information is not included in the metadata stored in the metadata storage means 8 (S130), the information comparison means 7 The error notification is transmitted to the user terminal 4 (S150). For example, when a third party fabricates hierarchical positional information, an object has an information code including the fabricated hierarchical positional information. At first glance, it is considered to be a legitimate object. Since the hierarchical positional information does not exist in the data, it can be determined that the object is illegal. By comparing the hierarchical positional information read in this way with the metadata, the processing can be performed as if it had been authenticated.

In addition, when hierarchical positional information does not exist in metadata, even if searching is performed based on the hierarchical positional information in each company server 3, there is no information corresponding to the hierarchical positional information. Therefore, inconsistency of the hierarchical position information can be determined before each company server 3 executes a search, and the processing can be speeded up.

The ticket receiving means 11 of each company server 3 (the company A in the above example) which received the ticket information from the information authentication gateway 2 in S140 temporarily stores it (S160). By this temporary storage, the ticket receiving means 11 of each company server 3 (here, A company server) delivers a notification of data preparation completion to the information authentication gateway 2.

The information authentication gateway 2 which received the notification of the data preparation completion from each company server 3 (here A company server), also receives the ticket information produced by the ticket issuing means 9 about the user terminal 4, too. To pass. At this time, information indicating which server should be accessed from each of the company servers 3 (here, address information of the server of A company, etc.) is also transmitted to the user terminal 4. For example, information such as "http: // A company server address / ticket information /" is transmitted. The information indicating which server should be accessed from each of the company servers 3 may be selected from a server (each company server 3) disclosed by a company, organization or the like on the Internet based on the hierarchical positional information.

And when the user terminal 4 receives ticket information from the information authentication gateway 2 (S160), each company server 3 which stores the information corresponding to the hierarchical position information read based on the information ( The server A is accessed, the ticket information received from the information authentication gateway 2 is transmitted, and a search request for information corresponding to the hierarchical position information is performed (S170).

The ticket comparing means 12 of the server (in this case, the server of A) which has been accessed among each of the company servers 3 includes the ticket information received by the ticket receiving means 11 from the information authentication gateway 2, and the user terminal. When ticket information received from (4) is compared (S180), and the access information is determined to be accessible, the search is allowed by the information search means 13, and when it is determined that access is not possible, an error is reported to the user terminal ( 4) to pass on.

After the permission of the search is made, the information retrieval means 13, based on the information of the hierarchical positional information ("A, X, XA") received from the user terminal 4, receives the information corresponding to the hierarchical positional information ( Here, the hierarchical position "A", the hierarchical position "X", and the information corresponding to the hierarchical position "XA") are retrieved from the information storage means 14, and the result is returned to the user terminal 4 (S190).

The result is received by the user terminal 4 and displayed or the like, whereby the user can know the attribute information attached to the object (S200).

In this case, the case where the attribute information is searched based on the hierarchical position information included in the information code attached to the article has been described. However, when the user requests a request for modification, deletion or new registration of the attribute information, etc. By inputting to 4), the information retrieval means 13 can also perform the process of correction, deletion, new registration, etc. of information corresponding to hierarchical positional information.

In addition, the metadata update means 10 accesses the information storage means 14 of each company server 3 at a predetermined timing or at a timing specified by an administrator of the information authentication gateway 2, It is also possible to detect the change in the hierarchical positional information at each server and store it in the metadata storage means 8. This makes it possible to always update the metadata with new information.

In addition, the information authentication gateway 2 transmits to the user terminal 4 information indicating which server of each of the company servers 3 should be accessed, and the user terminal 4 performs access based on the information. As a result, information corresponding to hierarchical positional information can be obtained by simultaneously accessing a plurality of servers.

In addition, the encryption of the information at the time of transmitting the search information which is the authentication information at the time of accessing each company server 3 from the user terminal 4 to the user terminal 4 from each company server 3 is carried out. It can also be used as a key. That is, the result of the processing of the information in the information retrieval means 13 is returned as a result to the user terminal 4 after encrypting the ticket information temporarily stored as an encryption key. The user terminal 4 which received the encrypted information decrypts the ticket information received from the information authentication gateway 2 as a decryption key, and reads the result. As a result, when the unauthorized access is made, the destroyed information is sent, thereby increasing the safety.

By providing metadata on the gateway, which is the data representing the entire hierarchical structure of the property of the article, based on the information read by the reader 5, comparing with the metadata in the gateway, the server of each company can search. In the past, it is determined whether or not there is information corresponding to the information. In addition, since the metadata manages which information resides on which server, it is also possible to retrieve information from a plurality of servers at the same time.
