How does the blockchain-based professional title review system achieve privacy protection of the review results?

Answer

The Hyperledger Fabric network provides the underlying platform service for the blockchain-based professional title review system. After receiving the professional title review request, the system calls the smart contract through the interface SDK to complete the review process on the Hyperledger Fabric network.

The user first registers and registers by calling the CA service to obtain the CA certificate. Then, the system administrator assigns the MSP certificate and initial key according to the user's role and stores the user information in the blockchain network.

The channel provides a private communication and transaction environment in the Hyperledger Fabric network. Channel management includes channel creation, channel update, channel joining and channel query.

The Peer node first needs to install the chain code locally, and then deploy the chain code by sending a request to instantiate the chain code. The process of instantiating the chain code includes creating a chain code image, starting the chain code container, and calling the chain code interface initialization.

After the qualified faculty and staff users log in to the system, they fill in and submit the application form and related supporting materials through the application and approval business application.

The external review experts query the external review materials in the material external review business application, and review the qualifications of the materials within the specified time, and feedback the review opinions to the system.

The subject group review experts are responsible for reviewing the application of the applicants, and refer to the application materials, personal performance reports, etc. to score the applicants.

The comprehensive evaluation method of the expert (evaluation) committee uses smart contracts to implement voting rules and strategies, and uses digital signatures and EC‑ElGamal encryption algorithms to ensure the privacy and immutability of voting, ensuring the fairness and justice of the review.

The difference review voting rules apply to the situation where the number of candidate review places is less than the number of candidate places, while the conditional review voting rules apply to the situation where the number of candidate review places is greater than or equal to the number of candidate places.

The system uses digital signatures and EC‑ElGamal encryption algorithms to encrypt the review results to ensure that only authorized users can view the results. At the same time, homomorphic encryption technology is used to implement ciphertext counting, which ensures the accuracy of counting while protecting privacy.

Key Terms

Term Definition Hyperledger Fabric An open source enterprise-level blockchain framework that provides a modular and configurable architecture. Blockchain (Blockchain) A distributed database that uses cryptographic technology to ensure data security and immutability. Smart Contract (Smart Contract) A piece of code running on the blockchain that is used to automatically execute predefined rules and terms. Consensus Mechanism (Consensus) An algorithm that all nodes in the blockchain network reach a consensus on to ensure the validity and consistency of data. Ordering Service is responsible for receiving transaction requests from clients, sorting transactions, and packaging sorted transactions into blocks. Peer Node is a node in the blockchain network, responsible for storing blockchain data, executing transactions, and maintaining the ledger. Channel is a private subnet in the Hyperledger Fabric network. Only members who join the channel can access the data and transactions in the channel. Chaincode is the code used to implement smart contracts. The chaincode runs in the blockchain network and can access and modify the ledger data. Digital Signature is a mechanism that uses cryptographic technology to sign data, which can verify the source and integrity of the data. EC‑ElGamal encryption algorithm is an encryption algorithm based on elliptic curve cryptography. It has additive homomorphism and can perform addition operations on ciphertext without decryption. It is suitable for scenarios that need to protect privacy. Summary

By studying this research guide, I hope you can better understand the concepts, processes, and advantages of the blockchain-based professional title evaluation method and system. I wish you a smooth study!
