The invention belongs to the technical field of informatization anti-counterfeiting, and particularly relates to a cloud picture comparison hot stamping alumite and a preparation method thereof.The alumite comprises a printing layer, a release holographic coating layer arranged at the lower end of the printing layer, a digital information layer arranged at the lower end of the release holographic coating layer, and a metal reflecting layer arranged at the lower end of the digital information layer; a holographic information layer is arranged in a hollow area of the metal reflecting layer, anti-counterfeiting dual verification is achieved through holographic information correspondence of a set two-dimensional code and physical characteristic particle points of the data information layer and set data of the holographic information layer, a consumer scans the two-dimensional code, rotates the label and inputs holographic verification data at a specific angle, and the anti-counterfeiting effect is achieved.
