[0002] As a decentralized ledger, blockchain uses a transaction format to securely store trusted data in an untrusted environment. Blockchain has unique characteristics such as decentralization, distribution, flexibility, tamper-proof and immutability. It has become a universal tool for storing various information across platforms. These inherent properties make blockchain particularly advantageous for digital archive systems in colleges and universities. The traditional consensus system process for archive data in blockchain is that one of the nodes in the blockchain initiates a data request, and the acquisition request is sent to each node in the blockchain for verification. When each node passes the verification, the node is allowed to enter the archive in the blockchain. This method is easy to leak the requester, the recipient and the content of the archive, and there is less judgment on the privacy of the archive.

[0003] From the above, it can be seen that how to achieve the situation where the requesting party can make the receiving party believe that the entered archive content is correct without revealing any archive content to the receiving party and prevent the leakage of digital archive content in colleges and universities is a problem to be solved in this field.

The blockchain has unique features such as decentralization, distribution, flexibility, anti-tampering, and immutability, and has become a common tool for storing various information across platforms. These inherent properties make the blockchain particularly advantageous in the application of the university digital archive system. The process of the archival data consensus system in the traditional blockchain is that one node in the blockchain initiates a data request, and this acquisition request is sent to each node in the blockchain for verification. When each node passes the verification, the node is allowed to enter the archive in the blockchain. This method is prone to leaking the requester, the recipient, and the content of the entered archive, and there is less judgment on the privacy of the archive. As can be seen from the above, how to enable the requester to make the recipient believe that the content of the entered archive is correct without leaking any archive content to the recipient and prevent the leakage of university digital archive content is a problem to be solved in this field.

[0074] Specifically, the archives generates the certification key and verification key based on the university identification parameters and the shared public key. The process for the collection node to generate the registration certificate is as follows: The archives generates the key required by the archive category , public key , SHA256 encryption algorithm and other public parameters, and publish the public parameters to each collection node in the network; the collection node k generates the key required by the archive category and the public key , and the key and the public key Sent to the archives; the archives receives the keys and public keys of all collection nodes in the network to generate a shared private key and shared public key , based on a shared public key and receive the identification parameters of college i to obtain the certification key of college i and verification key , and the proof key and verification key Sent to college i; college i calculates and generates the identification key and the public key , send the identification public key and the identification number The identity verification data is sent to the collection node k within the range; the collection node k generates the registration certificate of the college i based on the identity verification data , then the registration certificate Sent to the blockchain network for verification and preservation, and also sent to the college i; the college i receives the registration certificate Test its effectiveness.

If the archives have the identity registration information corresponding to the college, the archive data entry process is executed, that is, anonymous proof parameters are generated based on the proof key and verification key sent by the archives, and the anonymous proof parameters are sent to other colleges and universities except the college so that other colleges and universities can perform anonymous verification. If the anonymous verification is passed, the archive data to be entered will be entered into the blockchain network. Based on the blockchain technology, it is realized The requesting party can convince the receiving party that the entered archive content is correct without disclosing any archive content to the receiving party.
