specific Embodiment 1

[0037] This embodiment is an embodiment of a packaging system with information hiding function.

[0038] The packaging system with information hiding function of this embodiment includes an information hiding packaging box and an information decoding device,

[0039] 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 respectively provided with a first stepped structure and a second stepped structure;

[0040] The first step structure includes n step periods, and there are p in the i-th step period i steps, the height of each step cycle changes monotonically;

[0041] The second step structure includes...

specific Embodiment 2

[0044] This embodiment is an embodiment of a packaging system with information hiding function.

[0045] The packaging system with information hiding function of this embodiment, on the basis of the specific embodiment 1, further defines a facade with a stepped structure, with a stepped structure in the middle, and rails at both ends of the stepped structure.

[0046] The vehicle body is provided with wheels capable of traveling on the rails.

[0047] This example is in figure 2 The same applies in .

specific Embodiment 3

[0048] This embodiment is an embodiment of a method for identifying hidden information based on distance identification.

[0049] The hidden information identification method based on distance identification in this embodiment includes the following steps:

[0050] Step a, the information decoding device passes through the through hole according to a fixed direction, and records the corresponding relationship between distance and time f for the first step structure 1 (d,t), record the correspondence between distance and time for the second step structure f 2 (d, t), the corresponding relationship between the identification record label and time f 3 (n,t);

[0051] Step b, for f 1(d, t) to calculate the derivative, when the absolute value of the derivative is greater than the threshold, it is the step change time; in the step change time, if the derivative is less than 0, it is the ascending step, and if the derivative is greater than 0, it is the descending step; according ...

Abstract

The invention, which belongs to the technical fields of packaging and transportation, encryption and decryption, and information security, provides a distance-recognition-based hidden information recognition method. The method comprises: an information decoding device passes through a through hole in a fixed direction and correspondence relationships between distances and time as well correspondence relationships between marks and time in a first step structure and a second step structure are recorded respectively; changing rules of steps in the first step structure and the second step structure with time are determined; according to a time equal principle, a correspondence relationship between the step in the first step structure, the step in the second step structure, and the mark is determined; and on the basis of the correspondence relationship between the step in the first step structure, the step in the second step structure, and the mark, hidden information is identified. Therefore, a direct display way of individual information on an express document can be changed and thus a problem of individual information leakage through the express document can be solved.

Description

technical field [0001] The invention relates to a hidden information identification method based on distance identification, which belongs to the technical fields of packaging and transportation, encryption and decryption, and information security. Background technique [0002] Online shopping has become an indispensable way of consumption in people's lives, and express delivery has also become an important voucher for transactions between buyers and sellers. At present, since the personal information of both buyers and sellers will be directly displayed on the courier receipt, and the delivery will be carried out according to the information on the courier receipt, the personal information of both buyers and sellers will be completely exposed to the public at all stages of delivery, which will easily cause personal loss of information. According to the survey, more than 70% of personal information is leaked through express delivery documents, which has brought many trouble...
