[0002] Blockchain, as a decentralized ledger, securely stores trusted data in a trustless environment using transaction formats. With its unique characteristics such as decentralization, distribution, flexibility, tamper-proofness, and immutability, blockchain has become a common tool for storing various types of information across platforms. These inherent properties make blockchain particularly advantageous for applications in university digital archive systems. Traditional blockchain data consensus systems involve one node initiating a data request, which is then sent to every node in the blockchain for verification. Only when all nodes pass verification is the node allowed to enter the archive into the blockchain. This method is prone to revealing the requester, recipient, and the content of the entered archive, and it offers limited protection for archive privacy.

[0003] As can be seen from the above, how to ensure that the requesting party can convince the receiving party that the entered file content is correct without disclosing any file content, and how to prevent the leakage of digital file content in universities, is a problem that needs to be solved in this field. Summary of the Invention

[0007] If the judgment result is that the archives have identity registration information corresponding to the university, then an anonymous proof parameter is generated based on the proof key and verification key sent by the archives, and the anonymous proof parameter is sent to other universities besides the university, so that the other universities can perform anonymous verification of the anonymous proof parameter. If the anonymous verification is successful, the archive data to be entered is entered into the blockchain network.

[0008] If the determination result is that the archive does not have the identity registration information corresponding to the university, then the university identity recognition parameters are sent to the archive, the proof key and verification key generated by the archive based on the university identity recognition parameters and the shared public key are obtained, the university registration data is sent to the collection node, so that the collection node returns a registration certificate based on the university registration data, and then the process of generating anonymous proof parameters based on the proof key and verification key sent by the archive is executed to complete the university identity registration and archive data entry.

[0024] The archive data entry module is used to generate anonymous proof parameters based on the proof key and verification key sent by the archive if the judgment result is that the archive has identity registration information corresponding to the university. The anonymous proof parameters are then sent to other universities besides the university so that the other universities can perform anonymous verification of the anonymous proof parameters. If the anonymous verification is successful, the archive data to be entered is entered into the blockchain network.

[0025] The identity registration and data entry module is used to send university identity recognition parameters to the archives if the judgment result is that the archives do not have identity registration information corresponding to the university. It then obtains the proof key and verification key generated by the archives based on the university identity recognition parameters and the shared public key, sends the university registration data to the collection node, so that the collection node returns a registration certificate based on the university registration data, and then executes the process of generating anonymous proof parameters based on the proof key and verification key sent by the archives to complete the university identity registration and archive data entry.

[0040] Blockchain, as a decentralized ledger, securely stores trusted data in an untrusted environment using transaction formats. With its unique characteristics such as decentralization, distribution, flexibility, tamper-proofing, and immutability, blockchain has become a common tool for storing various types of information across platforms. These inherent properties make blockchain particularly advantageous for applications in university digital archive systems. Traditional blockchain data consensus systems involve one node initiating a data request, which is then sent to every node in the blockchain for verification. Only when all nodes pass verification is the request allowed to enter the archive into the blockchain. This method is prone to revealing the requester, recipient, and the entered archive content, and it offers limited protection for archive privacy. Therefore, how to ensure that the requester can convince the recipient that the entered archive content is correct without disclosing any archive content, and how to prevent the leakage of university digital archive content, is a problem that needs to be solved in this field.

If the anonymous verification is successful, the archive data to be entered is entered into the blockchain network.

Based on the proof key and verification key, anonymous proof parameters are generated and broadcast to other universities other than the university mentioned above, so that the other universities can use preset verification conditions to anonymously verify the anonymous proof parameters. When all preset verification conditions are met, it indicates that the anonymous verification is successful, and then the archive data to be entered is entered into the blockchain network.

[0045] The specific process for generating anonymous proof parameters is as follows: obtaining the proof key and verification key sent by the archives; calculating a polynomial based on the proof key; and using the verification key to calculate the polynomial to obtain transaction identification data; selecting random parameters; and encrypting the archive data to be entered using the transaction identification data and the random parameters to generate anonymous proof parameters.

[0067] Finally, the college i broadcasts the proof parameters. Send to other colleges.

[0068] The anonymous verification process includes:

[0069] The proof parameters received by other colleges from college i The verification condition is demonstrated as follows:

[0070] ;

[0071] If both the proof verification condition C1 and the proof verification condition C2 are met simultaneously, the college i can enter the archive data into the blockchain network.

[0072] Step S13: If the judgment result is that the archive does not have identity registration information corresponding to the university, then the university identity recognition parameters are sent to the archive, the proof key and verification key generated by the archive based on the university identity recognition parameters and the shared public key are obtained, the university registration data is sent to the collection node, so that the collection node returns a registration certificate based on the university registration data, and then the process of generating anonymous proof parameters based on the proof key and verification key sent by the archive is executed to complete the university identity registration and archive data entry.

University registration data is generated based on the identity recognition key and the identity recognition public key. The university registration data is sent to the collection node so that the collection node can generate a registration certificate based on the university registration data and send the registration certificate to the blockchain network and the universities to be registered and / or entered. Then, the registration certificate returned by the collection node is obtained. The registration certificate is validated. If the validity check passes, the process of generating anonymous proof parameters based on the proof key and verification key sent by the archive is executed to complete the university identity registration and archive data entry.

[0074] Specifically, the process by which the archives generate proof keys and verification keys based on the university's identity recognition parameters and shared public key, and the collection nodes generate registration certificates, is as follows: The archives generate keys required by the archive category. Public key The system publishes public parameters such as the SHA256 encryption algorithm to each collection node in the network; collection node k generates a key required for the file category. and public key and the key and public key Send to the archives; the archives receive the keys and public keys from all collecting nodes in the network and generate a shared private key. and shared public key Based on shared public key And obtain the proof key of college i by receiving the identity recognition parameters of college i. and verification key and will prove the key and verification key Send to College i; College i calculates and generates the identification key. and public key Send identification public key and the identification number The authentication data is sent to the collection node k within its range; the collection node k generates a registration certificate for college i based on the authentication data. Then the registration certificate The registration certificate is sent to the blockchain network for verification and storage, and simultaneously sent to the college i; the college i receives the registration certificate.

[0094] In addition to enabling anonymous consensus-based data entry between universities and other universities, this application can also enable anonymous consensus-based data entry between secondary colleges within a university; the anonymous consensus-based consensus includes processes for anonymity proof and anonymity verification.

[0095] The process of entering anonymous consensus data between secondary colleges within a university is as follows: Figure 2 As shown, (1) the archive generates an archive category key and broadcasts it to all collection nodes; (2) the archive receives the collection node key and the secondary college identity information, and generates a proof public key and sends it to the blockchain; (3) if the archive does not have identity registration information corresponding to secondary college A, it sends the identity registration verification data of secondary college A to the collection node; (4) the collection node returns the registration certificate to secondary college A and sends the registration certificate to the blockchain; (5) secondary college A sends the anonymous proof data to the blockchain; (6) secondary college A sends the anonymous proof data to other secondary colleges (such as secondary college B) outside of secondary college A; (7) secondary college B performs anonymous verification on the anonymous proof data; (8) accepts the information that the anonymous verification is successful; (9) secondary college A enters the archive data to be entered into the blockchain network to complete the archive data entry process of anonymous consensus among secondary colleges within a university.

The archives set initialization parameters for the digital archive system, which are used for authorization and authentication of network nodes. Collection nodes are responsible for specific regions and issue registration certificates to colleges within those regions. Colleges access the blockchain network to perform archive entry operations. Colleges do not maintain the blockchain in their local storage; they participate in the consensus process for archive entry by receiving anonymous verification information from the archives, preventing the leakage of archive information from other colleges. The blockchain network is established using a consortium blockchain and is used to store digital archive information. Access permissions are established to allow legitimate nodes to access the archive information.

If the archive contains identity registration information corresponding to a university, the archive data entry process is executed. This involves generating anonymous proof parameters based on the proof and verification keys sent by the archive, and sending these parameters to other universities for anonymous verification. If the anonymous verification is successful, the archive data to be entered is then entered into the blockchain network. Based on blockchain technology, this method achieves... The requesting party can convince the receiving party that the entered archival content is correct without disclosing any archival content. If the archive does not contain identity registration information corresponding to the university, the university identity registration is performed first, and then the archival data entry process is executed.
