Random solution imprinting pattern anti-counterfeit label based on image comparison

The utility model discloses a random solution imprinting pattern anti-counterfeit label based on image comparison. The electronic label comprises an information recording layer and a pattern layer which are sequentially arranged from top to bottom, the pattern layer is provided with a random pattern identification area formed by dripping, permeating and diffusing a colored solution, and the information recording layer is adhered to the upper portion of the pattern layer and allows the random pattern identification area to be exposed. According to the utility model, the pattern layer is provided with the random pattern identification area formed by dripping, permeating and diffusing the colored solution; due to the randomness of the capacity, the position, the color and the quantity of thecolored solution, the generated anti-counterfeiting pattern can be ensured to have stronger uniqueness, and due to the fact that the formed pattern has a complex edge outline, the difficulty and the cost of batch imitation an
