Abstract

After a thorough study of the characteristics of electronic evidence, an electronic evidence preservation scheme based on block chain and Merkle Tree is proposed. In this scheme, a P2P network technology is used to realize the decentralization of the system, an encryption algorithm is used to ensure the security of user data, Merkle tree technology is used to ensure non tampering and traceability of data, an improved consensus algorithm is designed to ensure data consistency between computing nodes, timestamp technology is used to ensure the existence of data in a specific time period or before a certain time, and block chain data structure is used to store electronic evidence. An electronic evidence preservation platform based on block chain and Merkle Tree is designed and constructed. This platform can achieve the decentralized electronic evidence preservation in the cloud computing environment, and prevent any involved participants, including evidence investigators, cloud service providers, users and so on, from colluding to tamper with the digital evidence. Experiments show that the scheme can effectively preserve and verify the electronic evidence, and guarantee the integrity and timeliness of the evidence data.
