Associated code anti-counterfeiting method, anti-counterfeiting paper and printing package

Patent name associated code anti-counterfeiting method and its anti-counterfeit paper and printing packaging patent applicant Hainan San Ben Technology Co., Ltd. The main applicant address Hainan City, Hainan Province, Yusha Road, Haohai District 14, Room 701 inventor Liu Xiaopeng application (patent) No. 02114656. X Application date 2002.07.03 Award date Approval notice number 1466081 Validation announcement date 2004.01.07 Manual CD-ROM number D0401 Main classification number G06F17/30 Classification number G06F17/30; G06K5/00 Division Original application number Priority item summary This invention provides An improved code anti-counterfeiting technology is proposed. It prints a group of codes on a cable or a security thread, and embeds the security thread in a specially-designed security code-proof printing and packaging paper. The two sets of codes in adjacent positions are stored as an associated code and each set of codes in an anti-counterfeit database. When consumers query each set of codes, they must also check the associated codes. Only when the codes and their associated codes are correct, the computer can Making a query is a true judgment. The present invention can effectively prevent counterfeiters from falsifying by recovering a code. Ming special anti paper step can be simplified and the cost of the user. Sovereignty item 1. An anti-counterfeit method of associated codes. It prints a set of group codes on the cable or security line (1) and stores the codes in a computer anti-counterfeit database. Consumers can use telephones and other communication tools to pull cables or security. The code on line (1) is input into the computer security database and compared with the record data to identify the authenticity of the product. It is characterized in that it includes the following steps: a. The length of the cable or security thread required for each individual product is used. L determines the arrangement density of the code on the cable or security line (1) to ensure that the number of coded characters printed in any L length range is greater than or equal to the number of characters of a set of code (2); b. Pull cable or security cable (1) Each set of codes is stored in the computer anti-counterfeiting database, and the adjacent code (3) before and after each code (2) on the cable or security line (1) is regarded as adjacent to the code (2). The associated codes are also stored in the computer anti-counterfeiting database; c. When the authentication is true or false, the consumer input cable or security line (1) consecutively arranged on the digital and computer anti-counterfeit database storage equipment The code (2) and the associated code collating section of the digital test input is not a security thread or wire (1) on the associated section of the digital code of the given truth judgment.
