Digital forensics is a critical technology for obtaining evidences in crime investigation. Now-a-days, the overwhelming magnitude of data and the lack of easy-to-deploy software are among the major obstacles in the field of digital forensics. Cloud computing, which is designed to support large scale data processing on commodity hardware, provides a solution. However, to support forensic examination efficiently using cloud, one has to overcome many challenges such as lack of understanding and experiences on configuring and using digital forensic analytic tools by the investigators, and lack of interoperability among the forensic data processing software.
