[0001] The present application belongs to the field of communication technology, and specifically relates to an anti-counterfeiting verification method, device and electronic equipment. Background Art

[0002] With the development of science and technology, the use of QR codes has become increasingly common in users' daily lives. In particular, by printing or affixing QR codes to product packaging, users can scan the QR codes on the product with their electronic devices, which will redirect them to an anti-counterfeiting verification webpage to obtain the authenticity of the product. This allows for product traceability through QR codes.

[0003] However, the QR code has a single function in this process, which is to provide the URL of the anti-counterfeiting verification web page. It is easy for illegal elements to tamper with and forge it, affecting the accuracy of the authenticity results. Summary of the Invention

In this way, the color information carried in the graphical code reduces the possibility of malicious attackers altering the graphical code of the target object, thereby increasing the security of the graphical code. Furthermore, because the arrangement of the code elements in the graphical code is not changed, only the colors of certain code elements are adjusted, so that the graphical code carries color information, the information stored in the graphical code is retained and the authenticity of the target object can be verified using the color information in the graphical code. Thus, the graphical code achieves a "one code, two uses" effect, effectively increasing the information capacity of the graphical code, ensuring the security of the graphical code, and preventing tampering with the graphical code, thereby improving the accuracy of authenticating the target object using the color information in the graphical code.

[0027] The following will be combined with the accompanying drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field fall within the scope of protection of this application.

[0028] The terms "first," "second," and the like in the specification and claims of this application are used to distinguish similar objects, and are not used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of this application can be implemented in an order other than that illustrated or described herein, and that the objects distinguished by "first," "second," and the like are generally of the same type, and do not limit the number of objects; for example, the first object can be one or more. In addition, the term "and / or" in the specification and claims refers to at least one of the connected objects, and the character " / " generally indicates that the objects connected are in an "or" relationship.

[0029] Counterfeit and substandard products harm the vital interests of businesses and consumers and seriously affect economic development. However, due to factors such as limited anti-counterfeiting technology and a single anti-counterfeiting method, most current product anti-counterfeiting solutions are imperfect. In order to combat counterfeit and substandard products and to provide a powerful "weapon" to trace problematic products, QR code anti-counterfeiting has emerged. A QR code (2-dimensional bar code) is a graphic that uses a certain geometric shape to record data symbol information in black and white distributed in a plane (two-dimensional direction) according to a certain pattern. In this way, QR code technology can be used to identify products and provide the URL of an anti-counterfeiting verification webpage. In this way, the QR code can be printed or affixed to the product packaging. The user can scan the QR code on the product with an electronic device to jump to the anti-counterfeiting verification webpage. Then, the user can scratch off the anti-counterfeiting layer on the product packaging and manually enter the product serial number under the anti-counterfeiting layer into the anti-counterfeiting verification webpage. Then, the authenticity result of the product can be obtained based on the product serial number.

[0030] However, in this process, since QR codes are easily modified, criminals can easily tamper with the address of the anti-counterfeiting verification webpage, resulting in inaccurate product authenticity results for users. This leads to low security of QR codes and low accuracy of the anti-counterfeiting information retrieved. Furthermore, since product serial numbers are generally long, this process increases the number of manual entries required by users, making the query process cumbersome and reducing the efficiency of anti-counterfeiting information retrieval.

[0031] Therefore, in response to the above-mentioned problems, an embodiment of the present application provides an anti-counterfeiting verification method for a target object based on the color information carried in a graphic code. The color information carried in the graphic code reduces the possibility that the graphic code of the target object may be changed by a malicious attacker, thereby increasing the security of the graphic code. In addition, since the arrangement structure of the code elements in the graphic code is not changed, only the colors of certain code elements in the graphic code are adjusted so that the graphic code carries color information. Therefore, the information stored in the graphic code is retained, and the authenticity of the target object can be verified through the color information in the graphic code. Thus, the graphic code achieves the effect of "one code for two uses", effectively increasing the information capacity of the graphic code, that is, ensuring the security of the graphic code and preventing the graphic code from being tampered with, thereby improving the accuracy of identifying the authenticity of the target object through the color information in the graphic code.

[0032] Based on this, the embodiment of the present application provides an anti-counterfeiting verification method. Figures 1 to 4 The anti-counterfeiting verification method provided in the embodiments of the present application is described in detail.

[0033] Figure 1 A flowchart of an anti-counterfeiting verification method provided in an embodiment of the present application.

[0034] like Figure 1As shown, the anti-counterfeiting verification method can be applied to electronic devices, based on which, it can specifically include the following steps:

[0035] Step 110, obtain the first graphic code corresponding to the target object at the current moment; the first graphic code carries color information; Step 120, obtain the verification string corresponding to the target object at the current moment; Step 130, determine the second graphic code corresponding to the target object at the current moment based on the verification string, the second graphic code carries color information; Step 140, determine the verification result of the target object based on the color information of the first graphic code and the color information of the second graphic code.

[0036] In this way, by obtaining the first graphical code corresponding to the target object at the current moment and a verification string, the first graphical code carries color information. Then, based on the verification string, the second graphical code corresponding to the target object at the current moment is determined. The second graphical code also carries color information. Thus, the verification result of the target object can be determined based on the color information of the first and second graphical codes. The color information carried in the graphical code reduces the possibility of malicious attackers altering the target object's graphical code, thereby increasing the security of the graphical code. Furthermore, because the arrangement of the code elements in the graphical code remains unchanged, only the colors of certain code elements are adjusted, allowing the graphical code to carry color information. This preserves the information stored in the graphical code and allows the authenticity of the target object to be verified using the color information in the graphical code. Thus, the graphical code achieves a "one code, two purposes" effect, effectively increasing the information capacity of the graphical code, ensuring the security of the graphical code and preventing tampering, thereby improving the accuracy of authenticating the target object using the color information in the graphical code.

[0037] The above steps are described in detail below.

[0038] First, step 110 is involved. In one or more possible embodiments, step 110 may specifically include:

[0039] Based on the object identification information of the target object, a first graphic code corresponding to the target object at the current moment is obtained from the server; wherein, the server determines the first encryption information corresponding to the target object at the current moment based on the verification string corresponding to the target object at the current moment, converts the first encryption information into a binary string, and adjusts the universal graphic code corresponding to the target object based on the color information corresponding to each character in the binary string at the current moment to obtain the first graphic code corresponding to the target object at the current moment, and associates the first graphic code with the object identification information of the target object; the universal graphic code is determined based on the object identification information of the target object.

[0040] It should be noted that the target object in the embodiment of the present application can be a product to be authenticated, which can be a physical product or a virtual electronic product. In this way, the object identification information of the target object can be a string of at least one of the following information: product serial number, product batch number, product anti-counterfeiting code.

[0041] Based on this, for example, the target object can be product A to be verified for authenticity. The user logs in to a web page or application for verifying the authenticity of product A through an electronic device, and enters the product serial number of product A in the web page or application, so that the request server calculates the first encryption information corresponding to product A at the current moment, such as a hash value, based on the verification string corresponding to product A at the current moment, such as a salt value (salt), converts the hash value into a binary string such as a 01 string, and adjusts the universal graphic code corresponding to product A according to the color information corresponding to the characters in the binary string at the current moment to obtain the first graphic code.

[0042] Here, as Figure 2 As shown, the universal graphic code 20 in the embodiment of the present application can be a black and white QR code, which can be a QR Code (Quick Response Code). Its version (Version) can be any of the 40 versions of the QR code (e.g., Version 1 to Version 40). In the embodiment of the present application, Version 1 (21×21) with a tolerance level of L is used as an example for illustration. It should be noted that since the achromatic code elements in the black and white QR code include black code elements 201 and white code elements 202, the process of adjusting the universal graphic code corresponding to product A based on the color information corresponding to the characters in the binary string at the current moment to obtain the first graphic code can be understood as adjusting the color of the black or white code elements based on the color information corresponding to the characters in the binary string at the current moment, such as 01, based on the color information corresponding to 0 corresponding to red (the code element corresponding to 1 remains unchanged), thereby obtaining the first graphic code carrying color information. The black and white code elements refer to the black and white blocks of a certain shape (e.g., square) that constitute the black and white QR code.

[0043] Next, step 120 may include:

[0044] According to the object identification information of the target object, obtain the verification string corresponding to the target object at the current moment from the server;

[0045] The server periodically updates the verification string corresponding to the target object.

[0046] For example, still referring to the above example, the target object can be product A to be verified for authenticity. The user logs in to a web page or application to verify the authenticity of product A through an electronic device, and enters the product serial number of product A in the web page or application, so that the request server is based on the verification string corresponding to product A at the current moment, such as a hash value.

[0047] It should be noted that the verification string can be obtained simultaneously with the first graphic code. In addition, since the server regularly updates the verification string corresponding to the target object, the first graphic code generated based on the verification string is also regularly updated and dynamically changed.

[0048] Next, step 130 is involved. In one or more possible embodiments, step 130 may specifically include:

[0049] Step 1301: Determine the second encrypted information corresponding to the target object at the current moment based on the verification string;

[0050] Step 1302, converting the second encrypted information into a binary string;

[0051] Step 1303, adjust the universal graphic code corresponding to the target object according to the color information corresponding to each character in the binary string at the current moment, and obtain the second graphic code corresponding to the target object at the current moment; the universal graphic code is determined according to the object identification information of the target object.

[0052] The above steps 1301 to 1303 are described in detail below.

[0053] In an example, the above-mentioned step 1301 may specifically include step 13011 and step 13012.

[0054] Step 13011: Determine the encrypted string corresponding to the target object at the current moment based on the verification string and the object identification information of the target object.

[0055] Among them, the first character of the verification string, such as the salt value, can be concatenated with the last character of the object identification information, such as the product serial number, to obtain the encrypted string str. For example, the salt value, such as "####", can be directly appended and concatenated after the product serial number "AAAAAA" to obtain the encrypted string str "AAAAAA####"; or, the verification string can be inserted into the product serial number to obtain the encrypted string str. For example, the salt value, such as "####", can be divided into "####" according to the preset character interval 1 to obtain "#", "#", "#" and "# ", then "#", "#", "#" and "#" can be inserted into the product serial number such as "AAAAAA" in sequence and at intervals to obtain the encrypted string str "A#A#A#A#AA", or, the salt value such as "####" is divided into "####" according to the preset character interval 2 to obtain "##" and "##", then "##" and "##" can be inserted into the product serial number such as "AAAAAA" at intervals to obtain the encrypted string str "A##A##AAAA", "AA##A##AAA", "A##AAAA##A", etc.

[0056] Step 13012: Encrypt the encrypted string according to a preset encryption algorithm to obtain the second encrypted information corresponding to the target object at the current moment.

[0057] Exemplarily, the encrypted string str can be encrypted by a preset encryption algorithm such as a hash algorithm to obtain second encrypted information such as a hash value or a hash value. Here, the preset encryption algorithm can include an MD5 algorithm, and the hash value can be represented in lowercase hexadecimal with a length of 16 bits.

[0058] Therefore, in the embodiments of the present application, message digest technology is used, that is, a check string such as a salt value is combined with object identification information such as a product serial number, and a hash value is generated using a preset encryption algorithm (such as MD5). Since the immutability of the object identification information is guaranteed by the performance of the hash function and the confidentiality of the check string, a slight change in the object identification information will cause a significant change in the final hash value. Therefore, the security of the graphic code (i.e., the first graphic code and the second graphic code) can be guaranteed, and the possibility of the graphic code being tampered with can be effectively prevented.

[0059] In another example, still taking step 1301 as an example, in the above-mentioned step 1302, the hash value (length is 16) can be converted into a decimal ASCII code, and then the decimal number can be converted into an 8-bit binary number, so that a 01 binary string with a length of 128 is obtained.

[0060] In another example, when the binary string includes characters of the first type and characters of the second type, and the universal graphic code corresponding to the target object includes a first color area and a second color area, step 1303 may specifically include:

[0061] According to the first color information corresponding to the first type of character, the first color area in the universal graphic code is adjusted, and according to the second color information corresponding to the second type of character, the second color area in the universal graphic code is adjusted to obtain the second graphic code corresponding to the target object at the current moment.

[0062] For example, still based on the above example, Figure 3 As shown, if the binary string includes a first type of character, i.e., 0, and a second type of character, i.e., 1, and the black and white two-dimensional code 20 includes a first color area, i.e., a black code element, and a second color area, i.e., a white code element, each code element in the black and white two-dimensional code is traversed. If the color of the code element is black, the black code element in the universal graphic code is adjusted according to the first color information corresponding to the first character of the first type, such as red, and the white code element in the universal graphic code is adjusted according to the second color information corresponding to the second type of character, i.e., blue, to obtain the second graphic code 30, as shown in FIG. Figure 3 As shown, the second graphic code includes an area 301 where the adjusted color code elements are located, and an area 302 where the black and white code elements are located.

[0063] It should be noted that the first color area and the second color area involved above can correspond to black code elements and white code elements respectively, or both can correspond to black code elements. In this way, the black code elements in the universal graphic code can be adjusted according to the red and blue colors. For example, the area corresponding to the black code elements is filled with color, and the white code elements in the universal graphic code remain unchanged. In this way, a target two-dimensional code with red code elements, blue code elements, black code elements and white code elements can be obtained.

[0064] At this point, it should be noted that the first or second graphic code in the embodiments of the present application does not change the arrangement of the various code elements in the universal graphic code. Therefore, the first or second graphic code includes the original content of the universal graphic code. In addition, due to the color adjustment of certain code elements in the universal graphic code, the first or second graphic code also includes colored code elements of different colors used to verify the authenticity of the target object. Here, the colored code elements in the embodiments of the present application include code elements corresponding to colors other than the black and white code elements in the achromatic code elements.

[0065] Furthermore, before step 1303, the anti-counterfeiting verification method may further include:

[0066] According to the object identification information of the target object, the color information corresponding to each type of character at the current moment is obtained from the server;

[0067] The server periodically updates the color information corresponding to each type of character.

[0068] For example, the first color information corresponding to the first type of characters and the second color information corresponding to the second type of characters mentioned above may be updated periodically by the server.

[0069] In this way, the client device obtains the first graphic code corresponding to the product at the current moment and the verification string (salt) corresponding to the product at the current moment from the server, and generates the second graphic code corresponding to the product at the current moment based on the verification string. If the color information of the first graphic code and the color information of the second graphic code are consistent, then the target object such as product A is authentic. Conversely, if the color information of the first graphic code and the color information of the second graphic code are inconsistent, then the target object such as product A is a counterfeit.

[0070] In addition, in addition to determining the second graphic code according to the method shown above, the embodiment of the present application also provides another method for determining the second graphic code, as shown below.

[0071] If the target object is a product, and the product appearance is marked with a second graphic code, then, in order to facilitate the subsequent verification of the authenticity of the target object, the user can take a picture of the product appearance marked with the second graphic code, that is, the electronic device captures the first image in the scan preview box, the first image includes the target object and the second graphic code, then recognizes the second graphic code, obtains the verification string in the second graphic code, and then obtains the color information in the second graphic code based on the verification string through the above method, which will not be repeated here.

[0072] Then, step 140 is involved. The above is an example of obtaining the first graphic code and the second graphic code, as well as the color information carried by the first graphic code and the color information carried by the second graphic code, so as to verify the authenticity of the target object based on these contents. In this way, the electronic device can be triggered to output the verification result of the target object in the following manner.

[0073] Then, involving 140, the user can compare the color information of the first graphic code with the color information of the second graphic code. At this time, if the color information of the first graphic code and the color information of the second graphic code are consistent, it means that the product including the second graphic code is authentic. Conversely, if the color information of the first graphic code and the color information of the second graphic code are inconsistent, it means that the product including the second graphic code is a counterfeit.

[0074] Therefore, in the embodiment of the present application, since the arrangement structure of the code elements in the universal graphic code is not changed and only the colors of certain code elements in the universal graphic code are adjusted, the information stored in the universal graphic code is retained and the authenticity of the target object can be verified through the color information in the universal graphic code. Therefore, the first graphic code and the second graphic code achieve the effect of "one code for two purposes", effectively increasing the information capacity of the universal graphic code, that is, ensuring the security of the graphic code, and improving the accuracy of identifying the authenticity of the target object through the second graphic code.

[0075] Furthermore, during the manufacturing process, the second graphic code can be recognized by a black and white camera, enabling rapid identification of different target objects and facilitating their management. For the user, electronic devices can use the graphic code, which carries color information, to obtain information about the target object and verify its authenticity. This eliminates the need for users to manually input the target object's identification information, simplifying the query process and improving the efficiency of querying anti-counterfeiting information.

[0076] In addition, since the provider of the target object does not need to maintain a complex authenticity query system and only needs to periodically change a specific string salt, the anti-counterfeiting verification method provided by the embodiment of the present application has lower maintenance costs.

[0077] Based on this, in order to better explain the above Figures 1 to 3 The anti-counterfeiting verification method shown is described in detail below, taking the object identification information corresponding to the target object, namely product A, such as the product serial number: 6920999701730, as an example, according to the anti-counterfeiting verification method provided in the embodiment of the present application.

[0078] In step 1, the target object can be product A to be verified. The user logs in to a webpage or application for verifying the authenticity of product A through an electronic device and enters the product serial number of product A on the webpage or application, so that the server is requested to verify the authenticity of product A based on the verification string corresponding to the current moment, such as the salt value (salt). Assuming that the verification string salt = 'vivo1' is specific within a certain period. Furthermore, based on salt = 'vivo1', the first encrypted information corresponding to product A at the current moment, such as the hash value 1, is calculated. The hash value 1 is converted into a binary string, such as a 01 string. Based on the color information corresponding to each character in the binary string at the current moment, the universal graphic code corresponding to product A is adjusted to obtain the first graphic code.

[0079] Step 2: Add salt = 'vivo1' to the product serial number 6920999701730 of product A to obtain an encrypted string, recorded as info, that is, info = '6920999701730vivo1'.

[0080] Step 3: Encrypt info using the MD5 function to obtain the second encrypted information, namely, hash value 2. The hash value is represented by a 16-bit lowercase hexadecimal number, which is recorded as hash='02e9758fa39435d2.

[0081] Step 4: Convert the hash value 2 into a decimal ASCII code, and then convert the decimal number into an 8-bit binary number to obtain a binary string.

[0082] Step 5: Adjust the universal graphic code corresponding to the target object based on the color information corresponding to each character in the binary string at the current moment, obtaining a second graphic code corresponding to the target object at the current moment. The universal graphic code is a black and white QR code containing the product serial number 6920999701730. The QR code selected here is Version 1 (21×21), a QR Code with a tolerance level of L, and the black and white QR code is recorded as black_qr. Each character in the hash = '02e9758fa39435d2, such as '0', is converted to the decimal ASCII code 48, and then 48 is converted to the 8-bit binary number 0011 0000. The binary string formed here will be filled into the QR code bit by bit using different colors. Furthermore, we can scan black_qr row by row in a row-first order. When we encounter a black square, we choose to fill it with the corresponding color. When we encounter a white square, we skip it and do not fill it with color. The color filling method can be freely selected as long as there is a large contrast between different colors. For ease of operation, the filling scheme used here is: red represents 0 in the binary string, and blue represents 1 in the binary string. Figure 3 The colors of the black squares in the first row after filling are: red, red, blue, blue, red, red, red, red. Repeat the above steps, convert each character in hash = '02e9758fa39435d2 into a binary string of length 8, and use the color information of the squares in the QR code to represent different characters, finally forming the following Figure 4 The QR code is shown in color.

[0083] It should be noted that the recognition of QR code information relies on the color difference between each small pattern and the QR code background. In the embodiment of this application, white is used as the background. The color of the QR code pattern is very different from white. Therefore, the target QR code with color can be correctly recognized by ordinary recognition devices. That is, in the production and circulation of products, ordinary recognition devices scan Figure 2 and Figure 4 The same result will be achieved; after seeing the product, the user can scan it with an electronic device Figure 4The graphic code in the image (which can be the universal QR code in step 5 above) can be used to obtain a salt, and then a second graphic code can be regenerated according to the above algorithm. If the color information of the newly generated second graphic code is inconsistent with the color information of the first graphic code obtained from the server, it can be considered that the QR code on the product is forged and the product is counterfeit. Conversely, if the color information of the newly generated second graphic code is consistent with the color information of the first graphic code obtained from the server, it can be considered that the QR code on the product is not forged and the product is authentic.

[0084] Thus, the server generates a hash value of the product at regular intervals, converts the hash value into a binary string, and assigns a color to each of the 01 characters in the binary string, adjusting the color of the black and white QR code generated based on the product's object identification information. Based on this, when the user obtains the salt at the current moment to generate the hash value at the current moment, the hash value is converted into a binary string, and each of the 01 characters in the binary string is assigned a color, adjusting the color of the black and white QR code generated based on the product's object identification information to obtain a second image code. If the generated colored second graphic code is consistent with the colored first graphic code obtained from the server, it means that it is authentic. In fact, the generated hash value needs to be consistent, and the colors corresponding to the 01 strings need to be consistent in order to generate a consistent colored QR code. In this way, through message digest technology, the verification string such as the salt value is combined with the object identification information such as the product serial number, and a preset encryption algorithm (such as MD5) is used to generate a hash value. Since the immutability of the object identification information is guaranteed by the performance of the hash function and the confidentiality of the check string, a slight change in the object identification information will cause a significant change in the final hash value. Thus, the security of the graphic code (i.e., the first graphic code and the second graphic code) can be guaranteed, effectively preventing the possibility of the graphic code being tampered with, thereby increasing the security of the graphic code. In addition, the anti-counterfeiting verification method provided by the embodiment of the present application does not change the arrangement structure of the code elements in the universal graphic code, but only adjusts the color of certain code elements in the universal graphic code. Therefore, the information stored in the universal graphic code is retained, and the authenticity of the product can be verified through the color information in the second graphic code generated by the universal graphic code. As a result, the second graphic code achieves the effect of "one code for two purposes", effectively increasing the information capacity of the initial QR code, that is, ensuring the security of the QR code, effectively increasing the information capacity of the graphic code, that is, ensuring the security of the graphic code, preventing the graphic code from being tampered with, and thus improving the accuracy of identifying the authenticity of the target object through the color information in the graphic code. In addition, for the user side, by using the electronic device to determine the first graphic code and the second image code, it is possible to obtain the object identification information of the product and to identify the authenticity of the product. During the product identification process, the user does not need to manually input the object identification information, which simplifies the query process and improves the efficiency of querying anti-counterfeiting information.
