Saw tooth code anti-counterfeiting method

Abstract

The invention discloses a saw tooth code anti-counterfeiting method. The saw tooth code anti-counterfeiting method comprises the following steps: printing codes or / and images and texts on an object to be printed by utilizing a printing machine, and forming individualized saw tooth edges at the edges of the codes or / and the images and texts; photographing and acquiring the individualized saw tooth edges of the codes or / and the images and texts; storing characteristic information of the photographed and acquired individualized saw tooth edges and coding information into a computer anti-counterfeiting inquiry system database accessed into the Internet and taking the information as anti-counterfeiting characteristic filing information for distinguishing the true from the false through checking by the public. According to the saw tooth code anti-counterfeiting method disclosed by the invention, the edges of the codes or / and the images and texts of a product are slightly deformed and are prepared into the individualized saw tooth edges; only pictures of the saw tooth edges are conveniently preserved when a product is automatically checked, and the pictures are used as the anti-counterfeiting characteristic filing information and are stored in the database, so that the investment is hardly increased, procedures are not increased and the cost is not increased; however, an anti-counterfeiting function is given to the product; the vulnerability that a thieve in the family is difficult to find of digital anti-counterfeiting technologies including electronic code counterfeiting prevention and the like is prevented.

Description

technical field [0001] The invention relates to an anti-counterfeiting method, in particular to a sawtooth code anti-counterfeiting method. Background technique [0002] Chinese patent document CN202563817U discloses a kind of " dynamic color code anti-counterfeiting mark ", and it designs 10-21 anti-counterfeiting digital Arabic characters into randomly changing color characters (ie variable information), in order to increase the difficulty of copying and making fakes. When checking and verifying, the data is completely consistent, and the color of each character is also consistent with the character feature color recorded in the database of the computer anti-counterfeiting query system, so that the logo can be deemed as true. [0003] Chinese patent document CN2476070Y discloses a "cipher graphic anti-counterfeiting mark", which has printed some random graphics (ie variable information) on the anti-counterfeiting mark, in order to increase the difficulty of copying and mak...

[0002] Chinese patent document CN202563817U discloses a "dynamic color code anti-counterfeiting mark", which designs 10-21 anti-counterfeiting digital Arabic characters into randomly changing colored characters (i.e. variable information), in order to increase the difficulty of copying and counterfeiting

[0003] Chinese patent document CN2476070Y discloses a kind of "password graphic anti-counterfeiting marker", which has printed some random graphics (i.e. variable information) on the anti-counterfeiting mark, in order to increase the difficulty of copying and counterfeiting

This document provides a method to block the loopholes in the code anti-counterfeiting technology ("a house thief is hard to prevent"), but the implementation is relatively complicated, which increases the difficulty and cost of printing
