Magic square multifunctional numerical code information anti-counterfeiting label and anti-counterfeiting method

Abstract

The invention discloses a magic square multifunctional digital information anti-fake label integrated with anti-counterfeit, logistical monitoring, lottery promoting and game promoting. The multifunctional digital anti-fake label comprises the label with ID code, anti-fake code and defect magic square; the anti-fake code has covering layer; the defect magic square is obtained in such way: selecting part of column, row or diagonal in an optional magic square as bidirectional correction number element, and then selecting about half of the numbers as label character number information as plain code printed on the label defect magic square. The invention makes the ID code, the anti-fake code and the defect magic square integrated in a label, and makes the label lottery information to hide in database correction code. The invention has multiple anti-counterfeiting ability including anti-fake correction before non-destructive purchase and destructive anti-fake authentication after purchase, which accomplishes commodity in set associative anti-counterfeit, and improves inquiry ratio of anti-fake label greatly by promoting lottery and promoting game; meanwhile, the encryption algorithm can be public, as well as the database.

Description

technical field [0001] The invention relates to a magic square multifunctional digital information anti-counterfeiting label integrating anti-counterfeiting, logistics, lottery tickets and games and an anti-counterfeiting method thereof. Background technique [0002] There are many kinds of anti-counterfeiting methods for existing commodities, such as common laser anti-counterfeiting, DNA reagent anti-counterfeiting, magnetic ink anti-counterfeiting, temperature-changing anti-counterfeiting, bar codes, and recently more popular digital anti-counterfeiting technologies. With the rapid development of science and technology, physical anti-counterfeiting technologies such as laser anti-counterfeiting and barcodes are very easy to be copied, and ordinary consumers generally cannot recognize the authenticity of laser anti-counterfeiting and other signs. Therefore, traditional anti-counterfeiting technologies have serious defects and it is difficult to achieve anti-counterfeiting. ...

AI Technical Summary

Problems solved by technology

However, the current digital anti-counterfeiting system has many shortcomings such as low anti-counterfeiting effect, single function, poor security, low query rate and difficulty in realizing two-way anti-counterfeiting verification.
