Abstract

The invention provides a random matrix moire fringe anti-fake pattern and a manufacturing and identifying method and application of the random matrix moire fringe anti-fake pattern. The random matrix moire fringe anti-fake pattern comprises four matrixes of two layers of hidden texts or six matrixes of three layers of hidden texts. The random matrix moire fringe anti-fake pattern has high information bearing capacity, random factors are added, the manufacturing difficulty is high, a common forger cannot copy the pattern, and therefore the random matrix moire fringe anti-fake patter has the good anti-fake function. The invisibility of the random matrix moire fringe anti-fake patter is remarkably higher than that of a common parallel line type moire fringe, the change of the direction formed by the text content hidden in parallel lines is not obvious, and no matter whether people see the random matrix moire fringe anti-fake with the naked eyes or a magnifying lens, people can only see chaotic dotted lines and cannot see the hidden content. The random matrix moire fringe anti-fake can be identified with a grating piece, the identification method is regular and controllable, and product anti-fake inspection can be more accurate and convenient.
