Digital forensic in cloudsim

Abstract

Digital forensic is the method of providing digital evidence in order to prove the crime in digital world. In context of cloud environment the term digital forensics becomes more challenging due to dynamic and decentralized nature of cloud. The research proposes the digital forensic technique using Cloudsim. Cloud simulator is a powerful tool for modeling, simulating and carry out experimentation. This research presents digital forensic technique in context of cloud environment using cloudsim. The scenario of crime is created by hacking the client’s sensitive data, which is stored in cloud. The tiled bitmap algorithm is used to detect tampering of database on cloud server which presents the potential evidence. Also the proposed method is used to store the file on cloud server using timestamp and encryption method to avoid hacking. The research focuses on one of the category of crime that is tampering of data on cloud server.
