With the continuous development of information technology, the construction of digital government is also accelerating.In the construction of digital government, smart contracts and homomorphic encryption technology of blockchain are combined.Based on the smart contract technology of the blockchain, this paper proposes a personal credit reporting privacy protection plan, which specifically includes the credit reporting system model and smart contract design.At the same time, it analyzes the specific operations such as adding access nodes and setting node permissions involved in this project.Through multi-party protection of personal privacy of credit investigation, automatic matching of user conditions for credit investigation access is realized.Since the solution in this article involves many contracts, we will further optimize the overall operating efficiency of the solution by strengthening the privacy protection during the message transfer process and improving the execution efficiency of the homomorphic encryption algorithm.
