The application discloses an anti-fake optical element and a preparation method thereof. The anti-fake optical element comprises a plane substrate, and is characterized in that the anti-fake optical element further comprises a surface optical anti-fake layer on the plane substrate; the surface optical anti-fake layer is composed of periodically distributed phase areas; each phase area is composed of a plurality of closely arranged stepped pixel blocks with different heights and the same square bottom surface; and the surface optical anti-fake layer forms an anti-fake pattern under visible light irradiation. The anti-fake optical element has the advantages of low processing cost, strong anti-fake ability, wide application range, clear anti-fake image and the like, and can be applied to the fields of currency, certificates, labels and the like.

This application relates to the field of biometric feature acquisition technology, specifically a biometric feature acquisition device, including an installation structure. The installation structure is equipped with a first biometric feature acquisition device and a second biometric feature acquisition device. The installation structure also includes a shielding mechanism, and a linkage component is provided between the second biometric feature acquisition device and the shielding mechanism. This biometric feature acquisition device, through its linkage design, ensures that the precision acquisition camera is always sealed and protected by the shielding plate when not in use, effectively preventing dust, moisture, fingerprint contamination, and physical scratches, significantly reducing maintenance frequency and failure rate. Furthermore, the entire authentication process must be completed through a real, continuous physical pressing action, achieving efficient liveness detection and effectively preventing attacks using photos, videos, or static molds. Simultaneously, the linkage mechanism increases the complexity and cost of fraud, achieving superior security and anti-counterfeiting advantages.

The utility model discloses a composite packaging material structure with built-in hidden anti-counterfeiting laser images and texts, which comprises a PET (polyethylene terephthalate) base film layer, a nano coating layer, an aluminized layer, a water-based glue layer and a paper layer, and the paper layer, the water-based environment-friendly glue layer, the vacuum aluminized layer and the nano coating layer are arranged from inside to outside. A local laser pattern layer is arranged between the nano coating layer and the PET base film layer close to the inner part, positioning cursor layers are arranged close to the two side edges, printing positioning cursor layers directly facing the positioning cursor layers are arranged close to the two side edges outside the PET base film layer, and a printing image-text layer directly facing the local laser pattern layer is arranged close to the inner part. The local laser pattern is arranged in the PET base film layer and is secondarily protected by the printing layer, on one hand, the laser pattern is protected and is not easy to damage, on the other hand, the laser pattern does not need to be arranged in the PET base film layer and is not easy to imitate, the anti-counterfeiting effect is better, the positioning cursor layer and the printing positioning cursor layer are arranged, registration positioning in the printing process is facilitated, and the anti-counterfeiting effect is improved. And the positioning precision is higher.

This invention discloses an anti-counterfeiting card and its manufacturing and verification methods. The card includes a first substrate layer, an intermediate layer, and a second substrate layer stacked sequentially from top to bottom. A first printing layer is disposed on the side of the first substrate layer opposite to the intermediate layer. The card has mounting holes that pass sequentially through the first printing layer, the first substrate layer, the intermediate layer, and the second substrate layer. Both the top and bottom of the mounting hole are open. A colored film containing silver halide photosensitive emulsion is disposed within the mounting hole. An anti-counterfeiting image is disposed on the colored film, including at least one of the following: numbers, personal signature, portrait, and pattern. A second printing layer is disposed on the side of the second substrate layer opposite to the intermediate layer. The anti-counterfeiting card of this invention has good anti-counterfeiting effect and is convenient to manufacture and verify.
