specific Embodiment 1

[0037] This embodiment is an embodiment of an information coding structure based on a circumferentially arranged step array.

[0038] The information coding structure based on the circumferentially arranged step array of this embodiment includes a coded inner layer and a sponge outer layer, the sponge outer layer is connected to the coded inner layer through a tearing line, and the surface of the coded inner layer is provided with a first disc, a second Second disc and third disc;

[0039] The schematic diagram of the information coding structure based on the circumferentially arranged step array before the outer layer of the sponge is torn apart is as follows: figure 1 shown;

[0040] The schematic diagram of the information coding structure based on the circumferentially arranged step array after the outer layer of the sponge is torn is as follows: figure 2 shown in figure 2 In , use black to represent high steps and white to represent low steps;

[0041] The first dis...

specific Embodiment 2

[0044] This embodiment is an embodiment of an information decoding method based on a circumferentially arranged step array.

[0045] The information decoding method based on the circumferentially arranged step array of this embodiment is implemented on the information coding structure based on the circumferentially arranged step array described in the first specific embodiment, and the method includes the following steps:

[0046] Step a, tearing off the outer layer of the sponge to expose the inner layer of the code;

[0047] Step b. Under the condition that the plane where the distance detection device is located is parallel to the plane where the inner layer of the code is located, take the center of the first disk as the center and take any length not exceeding the radius of the first disk as the radius, and run the distance detection device for one Circular trajectory, record the corresponding relationship between distance and angle for the first disc f 1 (d 1 ,α 1 ), ...

specific Embodiment 3

[0058] This embodiment is an embodiment of an information decoding method based on a circumferentially arranged step array.

[0059] The information decoding method based on the circumferentially arranged stepped array of this embodiment, on the basis of the second embodiment, further defines that step j includes the following steps:

[0060] Step j1, encoding the steps in the first disk, the encoding includes a period code and a step code;

[0061] Step j2, encoding the step in the second disk, the encoding includes a large period code, a small period code and a small step code;

[0062] Step j3, encoding the position line in the third disc, the encoding including the position code;

[0063] Step j1, step j2 and step j3 are executed synchronously or sequentially in any order;

[0064] The position code, the cycle code are consistent with the large cycle code, and the step code is consistent with the small cycle code;

[0065] Step j4. Based on the principle that the positi...

Abstract

The invention discloses an information decoding method based on a circumferentially-arranged step array and belongs to the fields of package and transportation, encryption and decryption and information security technology. According to the information decoding method based on the circumferentially-arranged step array, first, a sponge outer layer is torn to expose a coded inner layer; second, corresponding relations between distances and angles in a first disk, a second disk and a third disk are recorded respectively; third, the change law of steps along with the angles in the first disk and the second disk and the change law of a starting line and a position line along with the angles in the third disk are solved respectively; fourth, a starting position is found, and the corresponding relation between the steps in the first disk, the steps in the second disk and the position line in the third disk is determined; and last, hidden information is recognized according to the corresponding relation between the steps in the first disk, the steps in the second disk and the position line in the third disk. Through the method, the direct display mode of personal information on an express bill can be changed, and therefore the problem that the personal information leaks through the express bill is solved fundamentally.

Description

technical field [0001] The information decoding method based on the circumferentially arranged step array of the invention 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 troubles to peo...
