Detailed Description
For the purposes of making the objects, technical solutions and advantages of the present application more apparent, the present application will be further described in detail below with reference to the accompanying drawings.

As described in the background section, the related method for generating the verification code and the method for checking the verification code are also difficult to meet the actual anti-counterfeiting requirement of the product.
The applicant finds that in the process of implementing the application, the related verification code generation and verification mode is often that the verification code is generated in advance, the verification code is pasted on a product in a label pasting mode, and the verification code is sent to a verification code verification end by a user for verification, so that the main problem of the mode is that: the pre-generated verification code is easy to leak, and is further cracked.
In some other schemes, the verification code may be generated by a verification code generation mechanism built into the product, but in such schemes it is often necessary to set a complex encryption mechanism, so that additional hardware is required to support the operation of the encryption mechanism.
Based on this, one or more embodiments in the present application provide a method for generating a verification code and a method for checking a verification code, which dynamically generate a verification code based on a verification code generating end integrating a sequence code, a random code generating mechanism and an encryption mechanism, and decrypt and check the verification code by the verification code checking end based on a stored sequence and a decoding mechanism, so as to complete an anti-counterfeit verification process for a product.
Embodiments of the present application are described in detail below with reference to the accompanying drawings.
In the embodiment of the present application, in the specific example shown in fig. 1, a verification code generating end is provided in a product, a sequence code, a random code generating mechanism and an encryption mechanism are integrated in the verification code generating end, and based on the integrated mechanism, a verification code about the sequence code of the product can be generated.
The produced product can be a display device such as a display screen, a spliced screen, or other products; and the generated verification code can be regarded as the anti-counterfeiting code of the product.
Further, as shown in fig. 1, in the production process of the product, the above sequence code may be pre-written into the product, and the sequence code may be pre-uploaded to the verification code checking end.
The verification code checking end can be a data system with an operation function, a database or the like.
Further, in the production process, the sequence code written into each product can be uploaded to the verification code checking end in advance.
As shown in fig. 1, a user may obtain a verification code of a product through a user device, and send the verification code to a verification code checking end for checking.
Specifically, the user equipment may be a communication device such as a mobile communication terminal, and the user may acquire the verification code by using the user equipment in a manner such as scanning or manual input, and send the verification code to the data system for the data system to check.
Based on the verification code, the verification code is generated through the product, the user obtains the verification code, and the verification code is checked, so that the anti-counterfeiting verification process of the product can be completed.
Referring to fig. 2, the method for generating the verification code according to one embodiment of the present application is applied to a verification code generating end, and specifically includes the following steps:
step S201, randomly generating at least one random code by utilizing a hash algorithm.
In an embodiment of the present application, each random number may be mapped to one random code based on at least one random number generated in the authentication code generation end.
Specifically, the verification code generating end may generate a multi-bit random number by using a built-in random number generator, and may generate one or more random numbers according to specific requirements.
Further, for each generated random number, a hash algorithm may be utilized to map it to a random code.
Specifically, any multi-bit random number is input to a hash function preset in the verification code generation end, namely, a hash function, and a hash value corresponding to the random number, namely, a hash value is obtained through operation of the hash function.
Further, the hash value corresponding to the random number obtained by the operation can be used as a random code corresponding to the random number corresponding to each random number generated by the verification code generation end.
It can be seen that if the verification code generating end generates a random number, a random code can be obtained according to the random number, and if the verification code generating end generates a plurality of random numbers, a plurality of random codes can be obtained according to the random number, and the random numbers generated by the random number generator each time are different, so that the random codes mapped each time are different through a hash function.
In a specific example, taking a spliced screen product in a display device as an example, an anti-counterfeiting code generating end is mounted in the spliced screen product, when the spliced screen product is started, a generating process of the anti-counterfeiting code can be automatically started, and a triggering instruction can be sent to the spliced screen product to trigger the generating process of the anti-counterfeiting code.
The anti-counterfeiting code may be regarded as the anti-counterfeiting code in the foregoing embodiment, and based on this, the anti-counterfeiting code generating end may be regarded as the anti-counterfeiting code generating end and may be used to generate the anti-counterfeiting code.
Further, after the generation process of the anti-counterfeiting code is started, the built-in anti-counterfeiting code generation end of the spliced screen product triggers the random code generator to generate at least one multi-bit random number.
Further, the anti-counterfeiting code generating end maps each random number by utilizing a built-in hash function, so that a random code corresponding to the random number is obtained.
Step S202, combining all random codes with preset sequence codes to obtain a combined code.
In the embodiment of the present application, the random code mapped in the foregoing step may be combined with the sequence code written in advance to the verification code generating end, so as to obtain a combined code.
Specifically, in some embodiments, the resulting random code may be used as one field, while the preset sequence code is used as another field.
Further, the verification code generating end can splice the two fields into a combined code corresponding to the random code and the sequence code.
When only one random code is generated in the above steps, the random code is used as a field, and when a plurality of random codes are generated in the above steps, the plurality of random codes can be spliced into a field, then the fields related to the plurality of random codes and the fields of the sequence codes are spliced, and a combined code corresponding to the plurality of random codes and the sequence codes is obtained.
In other embodiments, other ways of combining the random code and the sequence code may be employed.
Specifically, when only one random code is generated in the foregoing step, the random code and the sequence code may be subjected to a binary operation, and the result obtained after the operation may be used as a combined code corresponding to the random code and the sequence code.
Further, when a plurality of random codes are generated in the foregoing step, the plurality of random codes may be first spliced into one field, the field related to the plurality of random codes and the sequence code are subjected to a binary operation, and the result obtained after the operation is used as a combined code corresponding to the plurality of random codes and the sequence code.
In a specific example, taking the spliced screen product in the previous step as an example, when at least one random code is generated by the anti-counterfeiting code generating end, all the random codes can be spliced into one field.
Further, a unique serial number may be written for each spliced screen product during the production of the spliced screen product.
Based on this, the fields related to the random code obtained above can be combined with the sequence code to obtain a combined code in which the random code and the corresponding sequence code are bound.
Step 203, encrypt the combined code with a preset private key to obtain a verification code, and display the verification code.
In the embodiment of the application, based on the combined code obtained in the previous step, the combined code may be encrypted, and the encrypted combined code is used as the verification code, and the verification code is displayed to the user.
Specifically, a key for encryption may be preset at the verification code generating end, where the key may be, for example, a private key for a symmetric encryption mechanism.
Based on this, the authentication code obtained in the foregoing step may be encrypted by means of AES (Advanced Encryption Standard ) using a preset private key, and an encrypted combination code may be obtained.
In this embodiment, the encrypted combined code may be used as the verification code, and the verification code may be displayed to the user, so that the user may obtain the verification code by reading or scanning.
In some other embodiments, the encrypted combined code may be subjected to digital-to-analog conversion, and the DAC code (digital-to-analog conversion code) obtained after conversion is used as the verification code and displayed.
Specifically, the encrypted combination code may be input to a preset DAC (digital-to-analog signal conversion) chip, and the DAC chip may be used to perform digital-to-analog conversion on the encrypted combination code.
Further, after conversion, the DAC chip outputs a DAC code, and in this embodiment, the DAC code may be used as an authentication code and displayed to the user, so that the user may obtain the authentication code by reading or scanning.
In a specific example, taking the spliced screen product in the previous step as an example, a private key for encryption may be set in advance at the anti-counterfeiting code generating end.
Based on the combined code generated by the anti-counterfeiting code generating end, the private key can be utilized to carry out AES encryption on the combined code.
Further, the encrypted combined code is used as an anti-counterfeiting code, and the anti-counterfeiting code is displayed to a user, so that the user can obtain the anti-counterfeiting code in a reading or scanning mode.
In the spliced screen product, the encrypted combined code can be input into a DAC chip for digital-to-analog conversion, and after the conversion, the DAC code obtained by conversion is used as an anti-fake code for display.
Therefore, the method for generating the verification code according to the embodiment of the application is based on the generated random code and based on the pre-written sequence code, the combination of the sequence code and the random code is comprehensively considered, the sequence code and the random code are bound and encrypted, so that the encrypted verification code is obtained, and the verification code generated by the verification code generating end is different each time due to the fact that the random code is bound in the verification code.
Referring to fig. 3, a verification code checking method according to another embodiment of the present application includes the following steps:
step S301, decrypting the verification code sent from the outside of the verification code checking end by using a preset private key to obtain a combined code, and determining a target sequence code from the combined code;
in the embodiment of the application, the verification code checking terminal can receive the verification code sent to the verification code checking terminal from the outside, decrypt the verification code by using a preset private key to obtain a combined code, and determine a target sequence code needing to be checked from the combined code.
Specifically, in the production process of the product, when the sequence code is written into the product and the private key is set in the product, the sequence code and the private key can be uploaded to the verification code checking end for storage.
Further, when the user sends the verification code to the verification code checking terminal, based on the received verification code, the verification code can be decrypted by utilizing a pre-stored private key.
And during decryption, based on the AES encryption mode adopted in the steps, adopting a corresponding AES decryption mode at the verification code checking end to decrypt the verification code.
Further, after decryption, a combined code may be obtained.
In some other embodiments, when the verification code received by the verification code checking terminal is in the form of a DAC code, the DAC code needs to be subjected to analog-digital conversion, and a combination code to be decrypted is obtained after the conversion, and based on this, the combination code to be decrypted is decrypted in an AES decryption manner, and the combination code is obtained.
Based on the splicing mode in the previous step, the verification code checking terminal can distinguish two fields of the spliced combined code from the combined code and distinguish a target sequence code needing to be checked from the two fields.
It can be seen that the target sequence code corresponding to the verification code corresponds to a product with the verification code.
In a specific example, taking the spliced screen product and the data system in the foregoing embodiment as an example, in the production process of the spliced screen product, when a unique sequence code is written into the spliced screen product, the sequence code is uploaded to the data system at the same time; and when a private key is preset for the spliced screen product, the private key is also preset into the data system.
Further, the data system may receive the anti-counterfeit code sent from the user equipment, and decrypt the anti-counterfeit code using a preset private key.
When the anti-counterfeiting code is a DAC code, analog-digital signal conversion can be performed on the DAC code, a to-be-decrypted combined code is obtained, and based on the to-be-decrypted combined code is decrypted by using the preset private key.
Further, after decryption, a combined code corresponding to the anti-counterfeiting code can be obtained, and a target sequence code corresponding to the anti-counterfeiting code is determined from the combined code.
In this embodiment, the target sequence code corresponds to a spliced screen product with the anti-counterfeiting code.
Step S302, checking whether the product sequence codes which are the same as the target sequence codes exist in the prestored product sequence codes.
In the embodiment of the present application, the verification may be performed on the target serial code based on a plurality of product serial codes stored in advance at the verification code verification terminal.
Specifically, based on the product sequence code of all the products pre-stored in the verification code checking terminal, the target sequence code obtained in the previous step can be compared with each product sequence code, so as to check whether the product sequence code identical to the target sequence code exists in all the product sequence codes.
In a specific example, taking the spliced screen products and the data system in the previous steps as examples, the product sequence codes of each spliced screen product are pre-stored in the data system, and based on the product sequence codes, whether the product sequence codes which are the same as the target sequence codes exist can be compared in all the product sequence codes.
Step S303, in response to the existence of the product sequence code identical to the target sequence code, determining that the verification code is valid.
In the embodiment of the present application, based on the comparison result of the foregoing steps, it may be determined whether the verification code is valid.
Specifically, when the comparison result shows that the product sequence code which is the same as the target sequence code exists in the product sequence code prestored in the verification code checking end, the target sequence code is considered to be a real and effective sequence code, and the verification code corresponding to the target sequence code is determined to be an effective verification code, namely, the product generating the verification code is a genuine product.
Further, when the comparison result shows that the product sequence code which is the same as the target sequence code does not exist in the product sequence code prestored in the verification code checking end, the target sequence code is considered to be an invalid sequence code, and the verification code corresponding to the target sequence code is determined to be an invalid verification code, namely, the product generating the verification code is a fake product.
In a specific example, taking the spliced screen product and the data system in the previous step as an example, when the comparison result shows that the product sequence code which is the same as the target sequence code exists in the product sequence codes prestored in the data system, the target sequence code is considered to be a real and effective sequence code, and the anti-counterfeiting code corresponding to the target sequence code is determined to be an effective anti-counterfeiting code, that is, the spliced screen product for generating the anti-counterfeiting code is a genuine product.
Further, when the comparison result shows that the product sequence code which is the same as the target sequence code does not exist in the product sequence codes prestored in the data system, the target sequence code is considered to be an invalid sequence code, and the verification code corresponding to the target sequence code is determined to be an invalid anti-fake code, namely, a spliced screen product for generating the anti-fake code is a fake product.
Therefore, according to the verification code checking method, based on the received verification code, the verification code is decrypted, the combined code can be obtained, and the target sequence code forming the combined code is determined from the combined code, so that whether the target sequence code is truly effective or not is checked.
It should be noted that, the method of the embodiments of the present application may be performed by a single device, such as a computer or a server. The method of the embodiment can also be applied to a distributed scene, and is completed by mutually matching a plurality of devices. In the case of such a distributed scenario, one of the devices may perform only one or more steps of the methods of embodiments of the present application, which interact with each other to complete the methods.
