Along with the increasing use of cloud services, security threats are also increasing and attack methods are becoming more diverse. However, there are still few measures and policies to deal with security incidents in the cloud environment. Although many solutions have been proposed through research on digital forensics for responding to security incidents, but it is still difficult to prove the integrity of evidence collection and storage in the cloud environment. To solve these problems, in this paper, we propose a blockchain based data logging and integrity management system for cloud forensics. In addition, compare the performance of the proposed system with the other blockchain based cryptocurrency.
