Embodiment 1
[0050] Such as figure 1 As shown, the holographic hot stamping feature identification anti-counterfeiting mark includes a first printing layer 1, a plastic film layer 2, a release layer 3, a first glue layer 4, a second printing layer 7, The substrate layer 8 and the second glue layer 9, the first glue layer 4 and the second printing layer 7 are provided with a local positioning holographic hot stamping layer 5 and a local positioning random physical feature layer 6;
[0051] The anti-counterfeiting mark can be peeled off and is divided into a peeling part and a bottom part. The peeling part is the part above the release layer 3, and the bottom part is divided into the release layer 3 and the part below the release layer 3.
[0052] The information of the first printing layer 1 includes a feature code; the feature code is a set of random physical feature distributions obtained by collecting local positioning random regions on the random physical feature layer 6, performing mul...
Embodiment 2
[0071] Such as figure 2 As shown, the holographic hot stamping feature identification anti-counterfeiting mark includes a first printing layer 1, a plastic film layer 2, a release layer 3, a first glue layer 4, a second printing layer 7, The substrate layer 8 and the second glue layer 9, the first glue layer 4 and the second printing layer 7 are provided with a local positioning holographic hot stamping layer 5 and a local positioning random physical feature layer 6;
[0072] The anti-counterfeiting mark can be peeled off and is divided into a peeling part and a bottom part. The peeling part is the part above the release layer 3, and the bottom part is divided into the release layer 3 and the part below the release layer 3.
[0073] The information of the first printing layer 1 includes a feature code; the feature code is a set of random physical feature distributions obtained by collecting local positioning random regions on the random physical feature layer 6, performing mu...
