The present invention is derived from the research conducted as part of the information and communication standard development support project of the Ministry of Information and Communication and the Ministry of Information and Telecommunications Research and Development.

Recently, a radio frequency identification (RFID) tag containing a two-dimensional bar code or identification information is attached to an object, a reader reads the information, and an information processing system such as a host computer via wired or wireless network. The technology for processing information by transmitting it to the Internet is rapidly developing.

Readers, such as Radio Frequency Identification (RFID) readers, read the code recorded on the storage medium, convert it to Uniform Resource Name (URN) and Fully Qualified Domain Name (FQDN), and convert The information is sent to a domain server so that various contents corresponding to a code obtained from a storage medium can be obtained.

An object identifier is information indicating what kind of information is recorded on a storage medium, and when an identifier is recorded on a storage medium such as an electronic tag by an international organization such as the International Organization for Standardization (ISO), Standardized to be recorded together to indicate the type of identifier.

In a conventional multiple code interpretation technique, an object identifier (OID) recorded in a radio wave identification (RFID) tag is sent to a multiple code interpretation server, and meta information is obtained in response thereto. Meta information is typically stored on multiple code parsing servers and passed to the client at the request of the client.

Radio frequency identification (RFID) reader system converts a specific code into a form for querying a code interpretation server, and generally knows meta information. However, when a new code scheme is designed, since there is no meta information in the RFID reader system, the code cannot be converted into a form for querying a code interpretation server.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings and the contents described in the accompanying drawings, but the present invention is not limited or limited to the embodiments. Like reference numerals in the drawings denote like elements.

As a storage medium according to an exemplary embodiment of the present invention, an electronic storage medium such as a radio frequency identification (RFID) tag, a physical storage medium such as a two-dimensional bar code, or the like may be used. Although the invention has been described, the invention is not limited thereto.

1 is a diagram illustrating a configuration of a storage medium according to an example of the present invention. A storage medium according to an example of the present invention will be described with reference to FIG. 1.

Radio wave identification (RFID) tag according to an example of the present invention comprises a meta information 110 and a code 120.

The meta information 110 is recorded in the radio wave identification tag for conversion of the code 120 data.

The meta information 110 includes information about the format or type of the code 120, and includes information for generating a query message requesting location information of content corresponding to the code 120. Can be.

Code 120 in a radio frequency identification (RFID) system means a unique number or a combination of numbers and letters that identifies a particular item. Here, codes are generally classified into classification codes, identification codes, and attribute codes. Classification codes contain information grouping similar items into common categories, identification codes are codes for the purpose of clear identification of certain objects, and attribute codes give meaning to infer the attributes of a product. This is the code.

The role of the code 120 in a radio frequency identification (RFID) system is to uniquely identify a thing to which a radio frequency identification (RFID) tag is attached. Therefore, the radio frequency identification (RFID) code may be considered to correspond to the identification code of the above classification. Depending on the system using radio frequency identification (RFID), additional information may be assigned to the code to include classification and attribute information in the code, but in a radio system (RFID) system the code is for identification purposes.

The identification information may be used to find classification and attribute information through a query to another server.

Additional information is needed to interpret the Radio Frequency Identification (RFID) code as having accurate meaning. A radio frequency identification (RFID) code is apparently just a binary bit string consisting of '0' and '1', and by itself has no meaning. In order for this meaningless binary to have meaning, there must be extra information about what this binary means. For example, if there is information about a unique item identifier (UII) defined in ISO / IEC 15459 as information on this binary number, the binary number is ISO / IEC 15459. A unique item identifier (UII) defined in FIG. 5 may be interpreted as meaningful information.

Also, even if there is no information on what this binary means, it can have meaning in a system using this binary number. For example, the Electronic Product Code (EPC) system assumes that all binary numbers it processes are EPC codes. Thus, the EPC system will interpret all binary numbers read from tags created according to certain rules as EPC codes.

An example of the 64-bit code '1000000000000001011001101000000000000000000000000000000000000001' will be described. This code can be interpreted only if there is additional information, including the type or format of this code. If there is additional information that this code is defined in ISO / IEC 11784, or if the system that handles it handles only ISO / IEC 11784, then this code is' 1.00000000000000.1.0110011010 It is interpreted as '.00000000000000000000000000000000000001', and it can be interpreted to mean 'This tag is an animal recognition tag, and after this code, there is more data, the code used in Korea, and the serial number is 1.' On the other hand, examples of a system for processing codes include radio frequency identification (RFID) readers and related software, servers for code interpretation, and the like.

At present, numerous codes exist worldwide, and there is mCode, a dedicated code system for mobile radio frequency identification (RFID) services in Korea. In Japan, there is a unique code system called uCode, and ISO has defined a number of code systems for various purposes as well as for item management. In addition, standards such as ISO / IEC 15961 and 15962 are separately enacted to provide effective data implementation and application interfaces for reading and interpreting codes.

The uniqueness of the radio frequency identification (RFID) code means that it exists uniquely within a particular system and can only be interpreted within that system. For example, the code used in the application of handling air baggage can only be interpreted in the air baggage application area.
