  Smartphones have created a significant impact on the day to day activities of
every individual. Now a days a wide range of Smartphone applications are
available and it necessitates high computing resources in order to build these
applications. Cloud computing offers enormous resources and extends services to
resource-constrained mobile devices. Mobile Cloud Computing is emerging as a
key technology to utilize virtually unlimited resources over the Internet using
Smartphones. Offloading data and computations to improve productivity, enhance
performance, save energy, and improve user experience. Social network
applications largely utilize Mobile Cloud Computing to reap the benefits. The
social network has witnessed unprecedented growth in the recent years, and
millions of registered users access it using Smartphones. The mobile cloud
social network applications introduce not only convenience but also various
issues related to criminal and illegal activities. Despite being primarily used
to communicate and socialize with contacts, the multifarious and anonymous
nature of social networking websites increases susceptibility to cybercrimes.
Taking into account, the advantage of mobile cloud computing and popularity of
social network applications, it is essential to establish a forensic framework
based on mobile cloud platform that solves the problems of today forensic
requirements. In this paper we present a mobile cloud forensic framework that
allows the forensic investigator to collect the automated synchronized copies
of data on both mobile and cloud servers to prove the evidence of cloud usage.
We also show our preliminary results of this study.
