Query: The State of the Art Forensic Techniques in Mobile Cloud Environment: A
  Survey, Challenges and Current Trends   Smartphones have become popular in recent days due to the accessibility of a
wide range of applications. These sophisticated applications demand more
computing resources in a resource constraint smartphone. Cloud computing is the
motivating factor for the progress of these applications. The emerging mobile
cloud computing introduces a new architecture to offload smartphone and utilize
cloud computing technology to solve resource requirements. The popularity of
mobile cloud computing is an opportunity for misuse and unlawful activities.
Therefore, it is a challenging platform for digital forensic investigations due
to the non-availability of methodologies, tools and techniques. The aim of this
work is to analyze the forensic tools and methodologies for crime investigation
in a mobile cloud platform as it poses challenges in proving the evidence. The
advancement of forensic tools and methodologies are much slower than the
current technology development in mobile cloud computing. Thus, forces the
available tools, and techniques become increasingly obsolete. Therefore, it
opens up the door for the new forensic tools and techniques to cope up with
recent developments. Hence, this work presents a detailed survey of forensic
methodology and corresponding issues in a mobile device, cloud environment, and
mobile cloud applications. It mainly focuses on digital forensic issues related
to mobile cloud applications and also analyze the scope, challenges and
opportunities. Finally, this work reviewed the forensic procedures of two cloud
storage services used for mobile cloud applications such as Dropbox and
SkyDrive.
