[0002] With the wide application of two-dimensional code technology, especially in the fields of identity authentication, Internet of Things, and intelligent devices, as a form of information carrier, the security and reliability of two-dimensional codes have become increasingly important issues.

[0020] To make the objectives, technical solutions, and advantages of the present invention clearer, the following will clearly and completely describe the technical solutions in the present invention in conjunction with the drawings in the present invention. Obviously, the described embodiments are some, rather than all, of the embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0021] The following describes the dynamic two-dimensional code data identity authentication method of the present invention in conjunction with the drawings. Figure 1 It is a flowchart of the dynamic two-dimensional code data identity authentication method provided by the present invention. As Figure 1 shown, the method includes the following steps 101 to 104.

[0022] Step 101: Obtain the vector data of the face features, and use the vector data as the key to encrypt the target data to obtain the encrypted data.

[0023] In some embodiments, before transmitting the target data, obtain the vector data of the face features. Here, a face image can be input through a collection platform or device, and then an image processing model is called to extract the corresponding face features, and the vector data of the face features is stored. For example, it is stored in a smart terminal or locally using the Web API of the collection platform or device.

[0024] When it is necessary to transmit the target data, at this time, use the vector data in the smart terminal or locally as the key to encrypt the target data to obtain the encrypted data. The encryption process can be implemented using a symmetric encryption algorithm, and the target data is the data that needs to be transmitted, that is, the real-time measurement data or running data collected in the smart terminal or locally, such as the driving speed, driving distance of a vehicle or ship, longitude, latitude, regional coordinates of vehicle positioning, temperature, humidity of the natural environment, etc.

[0025] Step 102: Generate a dynamic QR code based on the encrypted data.

[0026] Next, use the dynamic QR code to perform the data transmission of the target data. Here, generate a dynamic QR code based on the encrypted data, and the generation method can adopt the commonly used Dynamsoft Barcode Reader technology in the prior art. Since the target data is collected in real time, the QR code generated from the encrypted data is a dynamic QR code to ensure real-time synchronization and update with the target data.

[0027] Step 103: Obtain the QR code data by reading the dynamic QR code.

[0028] After generating the dynamic QR code in Step 102, at this time, the mobile terminal or mobile device where the destination of the target data needs to be transmitted can be used to scan the dynamic QR code to read the QR code data, and obtain the QR code data by reading the dynamic QR code for subsequent data decoding to obtain the target data.

[0029] Step 104: When performing face verification, use the vector data for identity verification, and decrypt the QR code data when the identity verification is successful to obtain the decrypted target data.

[0030] Here, since the QR code data is generated from encrypted data, and the encrypted data is encrypted using the vector data of facial features, during decryption, facial verification is required, and identity verification is performed using the vector data. Only when the identity verification is successful can the vector data corresponding to the facial features be used to decrypt the QR code data, thereby obtaining the decrypted target data and realizing the data transmission of the target data.

[0031] In the embodiment of the present invention, when using the dynamic QR code to perform the data transmission of the target data, by combining technical means such as encryption, decryption, and facial identity verification, the security of the QR code data during the transmission process can be ensured, and the target data can be prevented from being stolen and maliciously tampered with.

[0032] In some embodiments, generating a dynamic QR code based on encrypted data includes: calling the MD5 algorithm to generate the first hash value of the encrypted data; performing string splicing processing on the encrypted data and the first hash value to obtain spliced data; generating a dynamic QR code according to the spliced data.

[0033] Here, after the target data is successfully encrypted, the MD5 algorithm can be called to generate the first hash value of the encrypted data. This hash value can be used as a label for the encrypted data to verify whether there is data loss and affect the integrity of the data after the QR code data is generated.

[0034] When generating the dynamic QR code, the encrypted data and the first hash value are subjected to string splicing processing to obtain spliced data. Specifically, the strings of the encrypted data and the first hash value are spliced together through the "|" delimiter to form a new spliced string. Finally, by using the Dynamsoft Barcode Reader technology, the spliced string can be used to generate the corresponding dynamic QR code.

[0035] In the embodiment of the present invention, when generating a dynamic QR code from encrypted data, the MD5 algorithm is used to generate the hash value of the encrypted data, and a dynamic QR code is generated together with the encrypted data, which is convenient for subsequent verification of the integrity of data transmission and timely discovery of data loss.

[0036] In some embodiments, after obtaining the QR code data by reading the dynamic QR code, it further includes: respectively identifying the split encrypted data and the first hash value from the QR code data; calling the MD5 algorithm to calculate the second hash value of the split encrypted data; verifying the first hash value and the second hash value.

[0037] Specifically, after obtaining the QR code data by reading the dynamic QR code, the target data transmission process is completed through the dynamic QR code. At this time, the integrity of the target data needs to be determined before decryption. First, the encrypted data and the first hash value after splitting are respectively confirmed from the read QR code data. Here, the "|" separator in the QR code data is identified through string detection, and the string of the QR code data is split to obtain the encrypted data and the first hash value after splitting.

[0038] Next, the MD5 algorithm is called again to calculate a hash value for the split encrypted data, and then the calculated hash value is compared with the original first hash value obtained after the split to verify the integrity of the encrypted data.

[0039] In the embodiment of the present invention, when completing data transmission through a dynamic two-dimensional code, the MD5 algorithm is used again to generate a hash value of the encrypted data, and the integrity verification of the target data is implemented through hash value comparison, thereby ensuring the effectiveness of the data integrity verification.

[0040] On the basis of the above embodiment, when verifying the first hash value and the second hash value, when the first hash value is equal to the second hash value, the encrypted data after splitting is used as the two-dimensional code data for decryption. Here, when the hash values ​​generated twice are the same, it means that the target data is complete when the dynamic two-dimensional code is used for data transmission, and there is no data loss phenomenon. Then, the encrypted data after splitting can be used as the two-dimensional code data for decryption, and the subsequent decryption process of the target data is executed.

[0041] When the first hash value is not equal to the second hash value, the encrypted data after splitting is discarded. Here, when the hash values ​​generated twice are different, it means that the target data is lost when the dynamic QR code is used for data transmission, the data is incomplete, and the data is no longer suitable for data transmission. In this case, the encrypted data after splitting is discarded, and there is no need to perform the next step of data decryption process.

[0042] When executing data transmission of target data, the embodiment of the present invention determines the integrity of data transmission by comparing hash values. When the verification is incomplete, the data decryption process is decisively discarded and terminated, thereby ensuring the data transmission quality and the real-time and validity of the target data.

[0043] In some embodiments, when performing face verification, vector data is used for identity authentication, including: obtaining a vector to be verified of facial features extracted during face verification; comparing the vector to be verified with the vector data; when the comparison is consistent, determining that the identity authentication is successful; when the comparison is inconsistent, determining that the identity authentication has failed.

[0044] Here, face verification can be performed at the destination of the target data transmission because the target data is encrypted with vector data of facial features. After obtaining the QR code data by reading the dynamic QR code, identity verification must be performed through facial features to complete the decryption of the QR code data and obtain the target data.

[0045] During face verification, the corresponding face image can be directly obtained, and then the corresponding facial features can be extracted using the corresponding image processing model, so that the vector to be verified of the facial features can be obtained. Then, the vector to be verified is compared with the vector data for identity verification. The comparison method can be to calculate the similarity of the two vectors. When the similarity is greater than the similarity threshold (e.g., 99%), it indicates that the comparison is consistent; otherwise, the comparison is inconsistent.

[0046] When the comparison is consistent, it is determined that the identity verification is successful and it is determined to be the same person. In this way, the encrypted data in the QR code data can be decrypted using the vector to be verified of the facial features to obtain the target data. If the comparison is inconsistent, it is determined that the identity verification fails and it cannot be determined to be the same person. At this time, the vector to be verified of the facial features cannot perform the decryption of the encrypted data, and thus the target data cannot be obtained.

[0047] In the embodiments of the present invention, when performing data transmission of target data through a dynamic QR code, the biometric information of the face is used as a key to perform encryption and decoding of the target data, which can effectively prevent traditional passwords and keys from being stolen, copied, or cracked, provide a more secure identity authentication method than traditional authentication methods, and further enhance the security of the target data.

[0048] In some embodiments, before using the vector data as a key, it further includes: performing identity authorization on the vector data; and calling the PCA dimensionality reduction algorithm to perform compression processing on the vector data after identity authorization.

[0049] Here, before encrypting with the vector data of facial features, identity authorization is first performed on the vector data so that it can be used as a key for data encryption, which can ensure the effectiveness of identity verification before data decryption and ensure the successful execution of data decryption to obtain the target data. And calling the PCA dimensionality reduction algorithm to perform compression processing on the vector data after identity authorization can map the facial feature information from high-dimensional data to a low-dimensional space, reduce the dimension of the data, thereby simplifying the data structure, making data processing and analysis more efficient, and at the same time reducing information loss and ensuring the accuracy of identity verification.

[0050] Next, the dynamic QR code data identity authentication device provided by the present invention will be described.
