The most common two-dimensional code is a square two-dimensional code, the three corners of the upper left, the lower left and the upper right are provided with 'Chinese character' as the basis for identification and positioning, and then square patterns with alternating black and white are filled in the two-dimensional code to form a two-dimensional code image. The obvious problems of the existing two-dimensional code are as follows: because the identification positioning occupies a large area, the information area which can be stored is relatively limited, and the logic 0 or 1 is directly represented by a square block, the two-dimensional code area occupied by one byte of information is also large, so that the data capacity which can be stored by the two-dimensional code is very limited. Then, damage to the two-dimensional code such as offset can also lead to the two-dimensional code to be unrecognizable, and damage resistance is limited.

Referring to fig. 1 to 6, the present embodiment provides a micro code encryption method, in which the encryption process is a process of generating a micro code from data to be encrypted. As shown in fig. 2, wherein the first identifier and the second identifier may be geometric figures, such as five-pointed stars, circles, quadrilaterals, diamonds, hexagons, and the like. And whether the color is filled or not can be used as a second identifier which is different, the recognition difficulty can be reduced and the recognition efficiency can be improved through a simple geometric figure, and in other embodiments, the recognition can be other complex figures, characters, numbers, braille lattices and the like. The present embodiment is illustrated with a first identifier in number of one and a second identifier in number of ten. The method comprises the following steps:
step S101, input data to be encrypted is obtained, wherein the data to be encrypted comprises numbers, symbols, letters, chinese characters and the like; and encrypting the data to be encrypted according to an encryption rule to obtain a decimal digital character string. The encryption rule can only obtain decimal number character strings, for example, directly replacing symbols, chinese characters, letters and the like with decimal number character strings with the same number of bits. In some embodiments, the data to be encrypted may be converted into binary codes according to existing encoding rules, and then the binary codes may be converted into decimal codes. Of course, in order to improve the anti-interference and error correction capability, generally, after encryption using an encryption rule, a check number may be further set at the tail of the encrypted digital character string, so as to improve the error correction capability of the character string.
And then, step S102 is carried out to sequentially take values according to the numerical character string and the fixed bit number value rule, the obtained values are sequentially used as included angle information and distance information and are grouped, and each group comprises one included angle information and one distance information. If the number character string is twelve digits and the fixed digit is one digit, six groups can be obtained, each group contains included angle information of one digit and distance information of one digit, and if the included angle information of one digit cannot be divided, the included angle information of one digit is complemented with 0 to form a group. Then, in step S103, a preset first identifier is placed at the center position on the blank image; as shown in fig. 3. Typically, the blank image is a fixed size, generally square image, and in some embodiments, may be a circular image. And then place the first identifier in the middle of the image.
And then, step S104 is carried out, wherein the second identifiers of the preset second identifier information set are sequentially taken according to the group numbers of the included angle information and the distance information, and each second identifier is allocated with one group of the included angle information and the distance information. If the identifiers are fetched according to the sequence of the second identifiers, the second identifiers are placed on the blank image by taking the distance information as the distance information between the second identifiers and the first identifiers, and the included angle information is taken as the included angle information between the second identifiers and the next second identifiers and is used for the placement operation of the next second identifier position until all fetched second identifiers are placed on the blank image. If the first graph in the second identifier is a solid circle, the corresponding distance number is 5, and the angle number is 7. The distance information actually on the image is determined according to the actual situation, the minimum identifiable actual distance is taken as 1 unit distance (such as 10 px), and then the distance number is multiplied by the distance number (such as 5 is 50 px). The solid circular center is placed at 50px from the center of the first identifier, of course 0 is more specific, and in order to avoid covering the first identifier, encryption and decryption can be performed with 0 being 10. And the angle is also 1 unit (e.g., 5 °) based on the minimum angle that can be actually recognized. And multiplying the minimum angle by the actual angle number to obtain the actual angle, wherein the two minimum units are prestored in the encryption and decryption processes, and the encryption and decryption processes are consistent. The angle is the included angle of the connecting lines of the two second identifiers and the first identifier. Of course, the second identifier of the first should have an initial position of placement, such as may be placed directly above. And then the included angle is set in a set direction, such as clockwise or counterclockwise. This direction may be preset on both the encryption and decryption devices. Thus, after the second identifier is placed according to the distances and angles of all groups, the process proceeds to step S105, and the images of the first identifier and the second identifier are used as the microscopic code images. This completes the encryption of the string to the microscopic code. In one embodiment, the simple microscopic code generated is as shown in FIG. 3. Such a microcode has a large number of gaps in the middle thereof, and can be decoded as usual even when the gap region of the microcode is stained. The existing two-dimensional code is only stained in the interior, and the data identification is greatly influenced because the interior is a data area. The anti-fouling capability is improved relative to the two-dimensional code.
Specifically, in the identification process, namely, the decoding process of the micro code, as shown in fig. 6, a micro code decryption method is provided, which comprises the following steps: step S601 acquires input image data; such as the microcoded image of fig. 3. Then step S602 identifies the first identifier in the image data according to the preset first identifier information and identifies the position of the first identifier as the origin position (first identifier center position). Step S603, identifying a plurality of second identifiers in the image data according to a preset second identifier information set, that is, firstly identifying which second identifiers are second identifiers, and identifying a plurality of coordinate values of the plurality of second identifiers relative to the origin position; i.e. the location of the second identifier on the image is identified. And then, step S604 is carried out, according to the coordinate values and the origin position, the distance between each of the second identifiers and the origin is calculated, the connection is carried out, the included angle between the adjacent connection is calculated, the sequence value is obtained by arranging according to the sequence after the distance and the included angle are rounded, and the decoded value is obtained by adopting a preset decoding algorithm according to the sequence value. The rounding here is: obtaining an integer number after rounding according to the actual distance divided by the preset unit distance, obtaining an integer number after rounding according to the actual angle divided by the preset unit angle, and then starting to arrange numbers according to a first second identifier (the first second identifier in the second identifier set can be the first second identifier in the second identifier set, such as a solid circle in the drawing) and a preset sequence direction (such as a clockwise direction), so as to obtain a sequence value, and obtaining a decoded value by adopting a pre-stored sequence value decoding rule. The decoding algorithm here is the inverse of the above rule for obtaining the decimal digital encryption rule. Thus, a character string can be obtained. And can be practically applied according to the character string. The final number sequence is used for obtaining the character string through a decoding algorithm, and the character string can have more types instead of just numbers, so that the character string can be used in practice. The decryption process of the microcodes is completed through the whole process, and similarly, the microcodes can be decoded as usual when the gap areas of the microcodes are stained due to a plurality of gaps in the middles of the microcodes. The existing two-dimensional code is only stained in the interior, and the data identification is greatly influenced because the interior is a data area. The anti-fouling capability is improved relative to the two-dimensional code.
The encryption process of the invention can be independently stored in one device, and the decryption process can also be independently stored in one device, thus realizing independent encryption and decryption. Or in some embodiments, the encryption and decryption steps may be stored in a device at the same time, i.e. the data may be converted into a microscopic code, or the microscopic code may be converted into data.
Further, in order to further improve the anti-fouling recognition capability, as shown in fig. 4, the generated microscopic code image may be further arrayed on the image to form a code image having a plurality of microscopic codes. As shown in fig. 4, four images are shown after the array, so that only one image can be identified without smear. At this time, the influence of the second identifier of the other microscopic code on the image on the identifier to be recognized is avoided at the time of recognition. And the identification decryption is that, when the number of the first identifiers is more than one, an identification area is defined according to the average value of the distances between the two adjacent identifiers, the identification of the second identifier is carried out in the identification area, and the sequence value operation is carried out according to the second identifier identified in one identification area. The identification area is thus cut and then only identified in the identification area, so that the influence of the second identifier of the further first identifier on the current first identifier is avoided.
In some embodiments, if there is a microscopic loss in each of the different microscopic codes, then portions of the plurality of microscopic codes may be combined to complement one microscopic code. And when decrypting, the method further comprises the step of sequentially comparing the second identifiers in different identification areas, and if the second identifiers in the same position in different identification areas are missing, supplementing the missing second identifiers to the missing areas according to the identification areas with the second identifiers. This achieves a higher decryption capability of the corrupted microcodes.
In some embodiments, in the case of a change of the microscopic code, to further increase the data storage of the microscopic code, a sequence number is introduced to the second identifier and this sequence number is used as part of the encryption. Further, the second identifier has a sequence number, the obtained values are included angle information and distance information in order and the grouping includes the steps of: the obtained values are sequentially used as included angle information, distance information and second identifier number information and are grouped. The step of sequentially taking the second identifiers of the preset second identifier information set according to the group number of the included angle information and the distance information comprises the following steps: and sequentially taking the second identifiers of the preset second identifier information set according to the second identifier serial number information. That is, when grouping decimal strings, the number of grouping bits is increased by one bit, and the increased one-bit number is used to obtain the corresponding second identifier. If the original number is twelve digits, the distance and the angle of one digit are respectively taken and divided into six groups. After the serial number is added, each group respectively takes the distance, the angle and the serial number of one number, and only needs to be divided into four groups. The sequence number may be the first or last bit in each group. If the number in the first group is 5, the 5 th bit corresponding to the second identifier is a double-bar image. The dual-bar image is placed as the first second identifier image. And (5) placing in sequence. Thus, the information storage capacity is increased through the serial number of the second identifier, and more information is stored.
When decryption is performed at this time, the second identifier information set further includes a sequence number corresponding to the second identifier, and when the second identifier is identified, the second identifier information set further includes a sequence number identifying the second identifier, and according to the sequence number of the second identifier; the step of obtaining the sequence value by sequentially arranging the obtained sequence value after rounding according to the distance and the included angle comprises the following steps: and arranging according to the distance, the second identifier serial number and the included angle in sequence to obtain a sequence value. Since the direction is already determined and then the second identifier is used again for the sequence number, it is necessary to locate which of the first second identifiers is, which can be achieved by marking the first second identifier. If a straight line is connected between the first and second identifiers, it is known which is the first and second identifier, and the second identifier connected with the first identifier is identified as the first identifier when decryption. Or a small marking pattern is arranged beside the first second identifier, so that the first second identifier can be marked, or if the data volume is small, the second identifiers are small in number, a large blank exists between the first and the last second identifiers, and the first second identifier can be determined by the blank and the decryption direction (clockwise or anticlockwise).
When the distance is determined, as the picture can be enlarged or reduced, the actual distance can be confirmed by determining the size of the first identifier, for example, the distance can be directly determined according to the multiple of the size of the first identifier, and the size of the first identifier can be the diameter of the circle where the periphery of the first identifier is positioned. I.e. the measured distance between the second identifier and the first identifier, and then calculating the value of the distance from the first identifier. In some embodiments, a third identifier may also be appended, the third identifier being different from both the first identifier and the second identifier. Further, two identical third identifiers are taken, standard interval values of the two images are set to be used as a part of the images, and the two third identifiers are placed at specific positions (such as upper right corners) of the blank images. The third identifier has two functions, namely, the use of the unit distance is determined, the position of the center of the image, namely, the position of the first identifier is determined in turn, when the first identifier is stained, the position is identified through the third identifier, and then the position of the first identifier can be obtained according to the preset position relation of the third identifier in the image. Further, in decryption, if the first identifier is not recognized, the third identifiers of two of the image data are recognized directly according to the preset third identifiers, and the origin position of the first identifier is determined according to the positions of the preset two third identifiers in the image. Of course, when the image range is large, it is possible to recognize the origin positions of the plurality of first identifiers, and the origin position placed in the middle of the plurality of second identifiers may be selected. Thus, through the first identifier inside and the third identifier outside, double insurance identification on the original point position can be realized, and the anti-fouling capability is improved.
The schematic diagram of the invention is illustrated by using relatively large patterns, and in fact, the existing patterns have strong recognition capability, and can recognize very small patterns, so that the patterns can be made very small. In some embodiments, in the case of a larger data size, the present invention may further sequentially place the second identifiers after the first identifier is placed for one turn (i.e. the placed angle and the angle close to 360 degrees, and the placement will be greater than 360 degrees), and the remaining second identifiers are placed to the outer periphery of the placed first identifier in the order of the placed order (the same clockwise or counterclockwise order as the second identifier of the first turn), where the distance information plus the maximum distance of the first turn is the actual distance (e.g. the maximum distance of the first turn is 10, and the distance between the second identifier and the first identifier of the actual second turn is 14), and the first identifier is the origin of the included angle (the included angle is also the origin of the first identifier, and the included angle between the two adjacent second identifiers is the same as the second identifier of the first turn), as shown in fig. 5. If the second turn is full, it can be extended to the third turn and placed in this way. The position of the first second identifier of the second turn is determined based on the angle between the last second identifier of the first turn. This allows more information to be encrypted. And during decryption, determining the number of turns of the second identifier according to the distance between the second identifier and the origin and the distance between each turn of the second identifier (for example, the first turn is 1-10, the second turn is 11-20), and obtaining a sequence value according to the sequence of the turns and from the outer ring to the inner ring. If the sequence value of each circle can be calculated, the final sequence value can be obtained after the sequence values of each circle obtained by sequentially combining the outer circle with the inner circle.

The encryption system of the invention realizes the encryption of data to the microcodes, and can also decode as usual when the gap area of the microcodes is stained because the microcodes have a plurality of gaps in the middle.
