Abstract

Abstract: An electronic forensics model of cloud computing based on blockchain was proposed, in which, an evidence prevention scheme based on Merkle Tree and an improved consensus algorithm were designed to implement the decentralized electronic forensics under cloud computing environment. This model can prevent any involved party-forensic investigators, cloud service providers, users, etc.-from colluding to tamper with the digital evidence. Experiments show that the model can effectively preserve and verify the electronic evidence, and guarantee the integrity and timeliness of the data.

Key words: electronic forensics, blockchain, decentralization, consensus algorithm
