Code marking processing system for article management, code judgment system, article management system, code marking method for article management, code judgment method, and information display object

Abstract

In the manufacturing-specific information database (20), information related to articles is stored in association with each other, and a group of information related to the article can be specified for each article. The first code generation unit (43) generates, for each article, a first code representing the content unique to the article by using a part of a set of information that can be identified for the article. The second code generation unit (44) generates a second code for each item, wherein the second code includes information on the content unique to each item in the above-mentioned group of information, and the information is not included in the first code. . A two-dimensional code generation unit (45) generates an optical information code (two-dimensional code) representing the first code, and an identification code generation unit (46) performs predetermined conversion processing on the second code to generate character string data (identification code). A print control unit (47) executes processing of marking the generated optical information code and character string data on the article or its accessories.

Description

technical field [0001] The present invention relates to a technique for marking codes representing genuine items on counterfeit products (for example, industrial products, branded goods, securities, credit cards, etc.) that may imitate genuine items, and a technology for judging whether the content of the marking is correct. [0002] In addition, the "marking (marking)" referred to in this specification refers to not only printing processing, but also various marking processing, embossing processing, etching processing, laser marking, etc. for fixing information content in a visible state. deal with. Background technique [0003] In recent years, there has been an increasing number of sophisticated counterfeit products that are difficult to distinguish from genuine ones, and in view of this situation, technology has been developed to enable easy identification of counterfeit products. Among them, the following technology is included: the information set for each item is enc...

Problems solved by technology

[0008] However, in Patent Documents 1 and 2, the information represented by the two-dimensional code and the information serving as the source of the information are printed on the same object, so it is possible to decipher encryption rules, etc. from the relationship between the two pieces of information.

In addition, in the case where a fake character string or two-dimensional code is printed according to the decrypted encryption rules, it may not be possible to see through the falsification.

[0009] The present invention focuses on the above problems, and its object is to improve the reliability of each code by making it impossible to easily decipher the relationship between the optical information code and the character string, and to accurately judge whether the printed content is correct or not.
