specific Embodiment 1
[0036] This embodiment is an embodiment of a packaging system based on the information hiding function of stripe grayscale.
[0037] The packaging system based on the stripe grayscale information hiding function of this embodiment includes an information hiding packaging box and an information decoding device,
[0038] The structural diagram of the information hiding packaging box is as follows: figure 1 As shown, the information hiding packaging box should include a cardboard box body, and a through hole with a rectangular cross-sectional shape is provided in the longitudinal direction of the cardboard box body. The two end faces of the through hole are sealed with opaque films, and the opposite sides of the through hole The two facades are drawn with the first grayscale stripe and the second grayscale stripe respectively;
[0039] The first gray-scale stripes include n stripe periods, and there are p in the i-th stripe period i fringes, the fringe grayscale changes monoton...
specific Embodiment 2
[0043] This embodiment is an embodiment of a hidden information identification method based on grayscale identification.
[0044] The hidden information identification method based on grayscale identification in this embodiment includes the following steps:
[0045] Step a, the information decoding device passes through the through hole according to a fixed direction, and records the corresponding relationship f between brightness and time for the first grayscale stripe 1 (l, t), the correspondence between the brightness and time of the second grayscale stripe record f 2 (l, t), the corresponding relationship between the identification record label and time f 3 (n,t);
[0046] Step b, for f 1 (l, t) Calculate the derivative, when the absolute value of the derivative is greater than the threshold, it is the stripe change time; in the stripe change time, if the derivative is less than 0, the gray scale becomes larger, and if the derivative is greater than 0, the gray scale be...
specific Embodiment 3
[0056] This embodiment is an embodiment of a hidden information identification method based on grayscale identification.
[0057] The hidden information identification method based on grayscale identification in this embodiment, with figure 1 The structure of the information hiding package box shown is taken as an example to explain the specific steps of the method, including the following steps:
[0058] Step a, the information decoding device passes through the through hole according to a fixed direction, and records the corresponding relationship f between brightness and time for the first grayscale stripe 1 (l, t), the correspondence between the brightness and time of the second grayscale stripe record f 2 (l, t), the corresponding relationship between the identification record label and time f 3 (n,t);
[0059] For the first grayscale stripe, as time goes by, the distance presents two alternating periods of bright and dark; for the second grayscale stripe, the distance...
