The invention provides a non-R-angle anti-counterfeiting method. The non-R-angle anti-counterfeiting method comprises: arranging some randomly-distributed non-R-angle glitter powder on a product, wherein the width W of the glitter powder is less than or equal to 1.2 mm or 0.05 mm; storing and filing the characteristic information of the glitter powder into an anti-counterfeiting inspection systemdatabase; when the authenticity is checked, shooting the glitter powder by using a shooting mobile phone to obtain to-be-detected information of the glitter powder; matching and identifying the distribution position characteristics of the glitter powder and the distribution position characteristics of the glitter powder recorded in a database; if the distribution positions are matched and the sharp angle is not the R angle, feeding back the information that the identification conclusion is true to the photographing mobile phone; and if the distribution positions are not matched, or the sharp corner is an R corner, or the edge of the glitter powder is not smooth, feeding back the information that the identification conclusion is false to the photographing mobile phone. The method is simpleand feasible in production and implementation, and authenticity can be easily distinguished by using a mobile phone; and printing cannot be copied, so that the technical loophole that the existing digital anti-counterfeiting is difficult to prevent a thief is blocked.
