In response to the potential issues of tampering,forgery,and leakage in the electronic storage of law enforcement case data,this article proposes a data access control scheme that integrates IPFS+blockchain technology.The scheme is based on the DPOS consensus mechanism,combined with hash algorithm and asymmetric encryption algorithm,and uses Merkle tree to verify the integrity of data transmission in a semi distributed network.The incentive layer uses Token and smart contract reward and punishment mechanism to improve the accuracy of public security file transmission.The application results show that this scheme can ensure the confidentiality and immutability of archive content,which is of great significance in preventing favoritism,bending the law,and archive leakage.
