Marking processing system for article management code, code judging system, article management system, method for marking article management code, code judging method and information displaying object

Abstract

A plurality of kinds of information relating to articles are stored in a manufacture-coherent information data base (20) by being related, so as to specify for each article a group of information relating to each article. A first code generating section (43) generates for each article a first code that indicates contents inherent to the article by using a part of the group of information specified for each article. A second code generating section (44) generates for each article a second code that includes information, which is of contents inherent to each article in the group of information and not included in the first code. A two-dimensional code generating section (45) generates an optical information code (two-dimensional code) that indicates the first code, and an identification code generating section (46) performs prescribed conversion processing to the second code to create character string data (identification code). A print control section (47) executes marking processing to mark the generated optical information code and the character string data on the article or to the object attached to the article.

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.
