[0020] S11: Acquire a filter element identification image.

[0021] In one embodiment, the filter element identification image is obtained by photographing the filter element to be identified loaded on the filtering device by the imaging element on the filtering device. The filter element to be identified loaded on the filtering device may be the filter element installed when the filtering device leaves the factory, or may be the filter element replaced by the user. The imaging element may be any device capable of taking images, such as a camera; to solve the cost problem, a camera with the worst existing processing capability may be selected. When the filtering device is powered on, the imaging element may photograph the filter element to be identified to obtain a filter element identification image. In a specific embodiment, the filter element identification image may include only the filter element anti-counterfeiting mark, and the filter element anti-counterfeiting mark may be a QR code containing data information such as the production date, model, and expiration date of the filter element. In another specific embodiment, the filter element identification image may include an auxiliary identification mark and a filter element anti-counterfeiting mark; the auxiliary identification mark may be the trademark of the enterprise that produces the filter element.

[0022] S12: Based on the first recognition result of the filter element anti-counterfeiting mark in the filter element mark image, a second recognition result indicating whether the filter element to be recognized is counterfeit is obtained.

[0023] In one embodiment, the first recognition result includes the ciphertext data of the filter element anti-counterfeiting mark. Specifically, after the camera element on the filtering device captures the filter element identification image, the filter element identification image can be sent to the main control module in the filtering device, and the main control module identifies it to obtain a first recognition result; then based on the first recognition result, a second recognition result of whether the filter element to be identified is counterfeit is obtained. Among them, the second recognition result of whether the filter element to be identified is counterfeit based on the first recognition result can be executed by the main control module in the filtering device, that is, the main control module decrypts the ciphertext data to obtain the plaintext data of the filter element anti-counterfeiting mark, and determines whether the plaintext data is consistent with the encoding data of the filter element when it leaves the factory. If it is consistent, it indicates that the filter element has not been counterfeited; it can also be executed by a server connected to the filtering device, that is, the filtering device sends the first recognition result to the server, and the server processes it to obtain a second recognition result.

[0024] Specifically, the filter element anti-counterfeiting mark can be a QR code, and the QR code is identified to obtain the ciphertext data corresponding to the filter element anti-counterfeiting mark, and the ciphertext data can be obtained by encrypting the plaintext data including the production date, model, validity period, etc. of the filter element. In a specific embodiment, the second identification result is determined by the server based on the association information corresponding to the filter element to be identified, and the association information is obtained based on the plaintext data corresponding to the filter element anti-counterfeiting mark. The association information indicates whether the filter element to be identified is associated with other filtering devices, and the plaintext data is obtained by the server decrypting the ciphertext data received from the filtering device. Specifically, the filtering device sends the ciphertext data corresponding to the filter element anti-counterfeiting mark to the server, and the server decrypts the ciphertext data to obtain the plaintext data corresponding to the filter element anti-counterfeiting mark; judge whether the plaintext data conforms to the preset coding rule; wherein, the production information of the filter element is encoded according to the preset coding rule to obtain the plaintext data, and the production information of the filter element is the production date, model, validity period, etc. of the filter element. The plaintext data can be a string of characters, and the preset coding rule can be, for example, the meaning of each character in the plaintext data, for example, the first character represents the model, and the 2nd to 9th characters represent the production date. It can be understood that the preset coding rule is set by the user; in response to the plaintext data conforming to the preset coding rule, a second recognition result is obtained based on the plaintext data. In this embodiment, the server can also perform other steps, please refer to the second embodiment of the filter element anti-counterfeiting method provided in this application for details, which will not be described in detail here.

[0025] The above method can be performed only by the filtering device, which can include a device body, a camera element and a main control module carried by the device body, the camera element and the main control module are connected in communication, the camera element is used to photograph the filter element to be identified to obtain a filter element identification image, and the filter element to be identified is loaded on the device body. Specifically, the steps in the above method can be performed by the main control module; the main control module can be an electronic device including a memory, a communication circuit and a processor; the electronic device is, for example, a microcomputer, a server, etc.

[0026] By acquiring a filter element identification image, wherein the filter element identification image is obtained by photographing the filter element to be identified loaded on the filter device by the camera element on the filter device, and then based on the first identification result of the filter element anti-counterfeiting mark in the filter element identification image, a second identification result indicating whether the filter element to be identified is counterfeit is obtained, and the anti-counterfeiting detection of the filter element can be realized. Among them, the first identification result includes the ciphertext data of the filter element anti-counterfeiting mark, and the ciphertext data is transmitted during the communication process, which can minimize the possibility of the filter element anti-counterfeiting mark being stolen during the communication transmission process, and help to improve the security of the filter element anti-counterfeiting mark and the reliability of the filter element anti-counterfeiting detection.

[0027] In other embodiments, the filter element identification image includes an auxiliary identification mark and a filter element anti-counterfeiting mark. Before executing step S12, it can be determined whether the auxiliary identification mark in the filter element identification image is the same as the target identification mark; in response to the auxiliary identification mark being the same as the target identification mark, a first identification result based on the filter element anti-counterfeiting mark in the filter element identification image is executed to obtain a second identification result characterizing whether the filter element to be identified is counterfeit.

[0028] In one embodiment, whether the auxiliary identification mark in the filter element identification image is the same as the target identification mark can be determined by judging whether the pixel value of each pixel point in the second image data of the auxiliary identification mark in the filter element identification image is within a preset range; in response to the pixel value of each pixel point being within the preset range, the pixel value of each pixel point is converted into a grayscale value; based on the difference between the grayscale value and the standard grayscale value, it is determined whether the auxiliary identification mark is the same as the target identification mark; wherein the standard grayscale value is obtained by grayscale processing of the image data of the target identification mark.

[0029] Specifically, the filter element identification image can be identified first, and the second image area where the auxiliary identification mark is located can be determined. In one embodiment, the size of the filter element anti-counterfeiting mark and the location of the filter element anti-counterfeiting mark in the first image area of ​​the filter element identification image are known, and the size of the filter element anti-counterfeiting mark in the filter element identification image and the size of the auxiliary identification mark in the filter element identification image have a fixed relationship, such as the length of the filter element anti-counterfeiting mark and the auxiliary identification mark are the same, and the width of the filter element anti-counterfeiting mark is 3 times or 4 times the width of the auxiliary identification mark. After the position of the filter element anti-counterfeiting mark is known, the second image area where the auxiliary identification mark is located can be determined based on the size of the filter element anti-counterfeiting mark and the size relationship between the filter element anti-counterfeiting mark and the auxiliary identification mark. In another embodiment, the second image area where the auxiliary identification mark is located can also be determined based on the pixel value of each pixel in the filter element identification image. For example, if the filter element anti-counterfeiting mark is in black and white, and the auxiliary identification mark is in color, the second image area can be determined based on the different pixel values.

[0030] After determining the second image area, the second image data can be obtained; the second image data includes the pixel value of each pixel in the second image area, and it is determined whether the pixel value of each pixel is within the preset range; due to different shooting lights, the pixel value of the same pixel in two images taken at the same shooting angle for the same object may be different, so a preset range is set, such as the range above and below the RGB value center of the target color, and the target color is the color that the second image area should display. In a specific embodiment, if the pixel value of each pixel is within the preset range, the pixel value of each pixel is converted into a grayscale value, and the grayscale value can be between 0-255. Based on the difference between the grayscale value and the standard grayscale value, it is determined whether the auxiliary identification mark is the same as the target identification mark; wherein the standard grayscale value is obtained by grayscale processing the image data of the target identification mark. In response to the difference being within the preset difference range, it is determined that the auxiliary identification mark in the filter element identification image is the same as the target identification mark; in response to the difference not being within the preset difference range, it is determined that the auxiliary identification mark in the filter element identification image is different from the target identification mark. It can be understood that the preset range and the preset difference range can be set by the user as needed, and no specific limitation is made here. In another specific embodiment, if the pixel value of each pixel point is within a preset range, the pixel value of each pixel point is binarized so that the pixel value of each pixel point is 0 or 255, and it is determined whether the pixel value of each pixel point is the same as the standard pixel value, and the standard pixel value is obtained by binarizing the image data of the target identification mark; if they are the same, it is determined that the auxiliary identification mark is the same as the target identification mark.

[0031] In another embodiment, it is possible to determine whether the auxiliary identification mark in the filter element identification image is the same as the target identification mark by using the first hash value of the standard image and the second hash value of the second image data of the auxiliary identification mark in the filter element identification image. Specifically, the first hash value of the standard image is obtained, and the second hash value of the second image data of the auxiliary identification mark in the filter element identification image is obtained; based on the first hash value and the second hash value, it is determined whether the auxiliary identification mark is the same as the target identification mark. Specifically, the standard image contains a target identification mark, which may be the same size as the second image area where the auxiliary identification mark is located; the first hash value and the second hash value are obtained, and the Hamming distance between the first hash value and the second hash value is calculated; in response to the Hamming distance being less than the preset distance, it is determined that the auxiliary identification mark is the same as the target identification mark; in response to the Hamming distance being greater than the preset distance, it is determined that the auxiliary identification mark is different from the target identification mark. It can be understood that the preset distance can be set by the user, for example, set to 5, 10, etc.

[0032] In other embodiments, after obtaining the filter element identification image, the main control module in the filtering device can first compress the filter element identification image to obtain a compressed image; and determine whether the auxiliary identification mark is the same as the target identification mark based on the compressed image. The processor compresses the filter element identification image including: dividing the filter element identification image into at least one image block based on the processor's memory space; binarizing the image block to obtain a data block; specifically, obtaining the pixel extreme values ​​of each channel in the RGB color space of the filter element identification image; determining the binarization threshold based on the pixel extreme values ​​of each channel and the preset error, and the binarization threshold may include an upper limit value or a lower limit value. For example, the upper limit value of the R channel is 255 / 8-5, the upper limit value of the G channel is 255 / 4-10, and the upper limit value of the B channel is 255 / 8-5; the lower limit value of the R channel is 10; wherein 5 and 10 are the preset errors. Based on the binarization threshold, each pixel in the image block is binarized to obtain a data block; specifically, it is determined whether the pixel value of each pixel in each channel is greater than the upper limit of the channel, and in response to the pixel value of each pixel in each channel being greater than the upper limit, the pixel is binarized into a first value; or it is determined whether the pixel value of each pixel in each channel is less than the lower limit of the channel, and in response to the pixel value of each pixel in each channel being less than the lower limit, the pixel is binarized into a second value. Among them, the first value can be 0, which represents white; the second value can be 1, which represents black. At this time, the obtained data block only contains 0 and 1. Further, the data block is compressed to obtain a compressed block corresponding to the data block; the data block is divided into several sub-data blocks; for each sub-data block, each element in the sub-data block is weighted and averaged to obtain the compressed data corresponding to the sub-data block; using the compressed data corresponding to each sub-data block, a compressed block is obtained. Finally, based on the compressed blocks corresponding to each image block, a compressed image corresponding to the filter element identification image is obtained.

[0034] S21: receiving the ciphertext data corresponding to the filter element anti-counterfeiting mark sent by the filtering device.

[0035] Among them, the ciphertext data is obtained based on the recognition of the first image data of the filter element anti-counterfeiting mark in the filter element identification image, the filter element identification image also includes an auxiliary identification mark, and the filtering device sends the ciphertext data based on the auxiliary identification mark being the same as the target identification mark; the filter element identification image is obtained by photographing the filter element to be identified loaded in the filtering device.

[0036] This embodiment can be executed by a server, and the server can be a memory and a processor coupled to each other, and the processor is used to execute program instructions stored in the memory to execute steps S21 and S22. The filtering device sends the ciphertext data corresponding to the filter element anti-counterfeiting mark to the server. In one embodiment, before sending the ciphertext data corresponding to the filter element anti-counterfeiting mark to the server, the filtering device can first determine whether the auxiliary identification mark in the filter element identification image is the same as the target identification mark. The specific judgment steps can refer to the relevant steps in the aforementioned embodiment, which will not be repeated here. If the auxiliary identification mark and the target identification mark in the filter element identification image are the same, it indicates that the filter element in the filtering device is produced by the target manufacturer. Further, the filtering device recognizes the first image data of the filter element anti-counterfeiting mark in the filter element identification image, obtains the ciphertext data corresponding to the filter element anti-counterfeiting mark; and sends the ciphertext data to the server.

[0037] In another embodiment, the filtering device determines that the auxiliary identification mark and the target identification mark in the filter element identification image are the same, and identifies the first image data of the filter element anti-counterfeiting mark in the filter element identification image to obtain the ciphertext data corresponding to the filter element anti-counterfeiting mark; the ciphertext data can be decrypted to obtain the plaintext data corresponding to the filter element anti-counterfeiting mark; a preliminary judgment can be made on the plaintext data, for example, it can be determined whether the plaintext data conforms to the preset coding rules. The preset coding rules are used to encode the production information of the filter element according to the preset coding rules to obtain plaintext data when the filter element leaves the factory; when the plaintext data conforms to the preset coding rules, the ciphertext data corresponding to the filter element anti-counterfeiting mark is sent to the server.

[0038] S22: Process the ciphertext data to obtain an identification result indicating whether the filter element to be identified is forged.

[0039] After receiving the ciphertext data, the server decrypts the ciphertext data to obtain the plaintext data corresponding to the filter element anti-counterfeiting mark. In one embodiment, the plaintext data can be compared with the original data corresponding to the filter element anti-counterfeiting mark stored in the database to obtain a comparison result; based on the comparison result, the identification result can be determined. Among them, the original data is obtained by encoding the production information of the filter element to be identified when the filter element to be identified leaves the factory; the comparison result is that the plaintext data and the original data are consistent or the plaintext data and the original data are inconsistent. In response to the comparison result indicating that the plaintext data and the original data are consistent, it is determined that the filter element to be identified is counterfeit; in response to the comparison result indicating that the plaintext data and the original data are inconsistent, it is determined that the filter element to be identified is not counterfeit.

[0040] In another embodiment, the server may also obtain the device information of the filtering device, or receive the device information sent by the filtering device; compare the plaintext data with the original data corresponding to the filter element anti-counterfeiting mark stored in the database to obtain a comparison result, and the comparison result is that the plaintext data and the original data are consistent, which means that the filter element to be identified is manufactured by the target manufacturer. Further, in response to the comparison result indicating that the plaintext data and the original data are consistent, based on the device information and the plaintext data, it is determined whether the filter element to be identified has been associated with other filtering devices; the association information indicating whether the filter element to be identified has been associated with other filtering devices can be stored in the database, that is, the database is searched for association information indicating that the filter element to be identified has been associated with other filtering devices. If not, it indicates that the filter element to be identified has not been associated with other filtering devices. In response to the fact that the filter element to be identified has not been associated with other filtering devices, it is determined that the filter element to be identified is not counterfeit, and the filter element to be identified is associated with the filtering device; if there is information that the filter element to be identified has been associated with other filtering devices, in response to the fact that the filter element to be identified has been associated with other filtering devices, the filter element to be identified is determined to be counterfeit.

[0041] In this embodiment, each filter element will store the original data corresponding to its filter element anti-counterfeiting mark in the database when it leaves the factory. Therefore, when the filter element to be identified is used, the plain text data corresponding to the filter element anti-counterfeiting mark in the filter element to be identified can be compared with the original data to determine whether the filter element actually exists. Furthermore, since each filter element is unique and can only be associated with one filtering device, it is possible to determine whether the filter element to be identified has been associated with other filtering devices to determine whether the filter element to be identified has been counterfeited. In this way, when unscrupulous merchants copy the filter element anti-counterfeiting mark of the same filter element to be identified on a large scale, only at least two filtering devices need to be connected to the network, and the server can clearly know that the filter element to be identified has been counterfeited; the target manufacturer can locate the sales area of ​​the filtering device and the counterfeit filter element to be identified through the association information between the counterfeit filter element to be identified and the filtering device, and then hold the unscrupulous merchants accountable.

[0042] In the above method, before identifying the anti-counterfeiting mark of the filter element, it is first determined that the auxiliary identification mark is the same as the target identification mark. If they are the same, the anti-counterfeiting mark of the filter element is then identified; otherwise, the anti-counterfeiting mark of the filter element is not identified. This allows the target manufacturer to only perform anti-counterfeiting identification on the filter elements it produces, and will not mistakenly identify the filter elements produced by other manufacturers, thereby reducing the detection time and thus reducing the detection cost. Furthermore, as long as the filtering equipment is connected to the Internet, the interface determines whether the filter element to be identified is counterfeited through the server, rather than the user simply scanning the anti-counterfeiting mark of the filter element to determine whether the filter element is counterfeited. This allows the manufacturer of the filter element to be identified to clearly understand whether the filter element to be identified is counterfeit, which is convenient for the manufacturer to protect its rights.
