Mobile Forensics: an Overview, and Challenges from Symbian OS Perspective
Mobile phone proliferation in our societies is on the increase. Advances in semiconductor technologies related to mobile phones and the increase of computing power of mobile phones led to an increase of functionality of mobile phones while keeping the size of such devices small enough to fit in a pocket. This led mobile phones to become portable data carriers. This in turn increased the potential for data stored on mobile phone handsets to be used as evidence in civil or criminal cases. This examines the nature of some of the new pieces of information that can become potential evidence on mobile phones. It also discusses some of the emerging technologies and their potential impact on mobile phone based evidence. The paper will also cover some of the inherent differences between mobile phone forensics and computer forensics. It also highlights some of the weaknesses of mobile forensic toolkits and procedures. Finally, the paper proposes a new approach for Symbian OS based mobile phones for collection and reporting of evidence and associated challenges.
