Forensic investigation and analysis on digital evidence discovery through physical acquisition on smartphone

Cybercriminals are changing their strategies as users are less concerns on the smartphone and social networks security risks such as spams, that will threaten them as they are more dependent on the smartphone [1]. Thus, there's a need to perform the smartphone forensics analysis to retrieve and analysed the potentially great amounts and extremely valuable information on these devices. This paper investigates a wealth of personal and sensitive data by types of digital information as evidence and conducted forensic analysis on a popular smartphone Samsung Galaxy Note III. The standard approach applied to extract information from smartphone through physical acquisition and analysis using Cellebrite UFED. The results are presented to demonstrate the smartphone as a goldmine for investigators and as sources of digital evidence. Furthermore this research also presents the forensic tool and techniques for acquiring and examining digital evidence on this device. The evidence discovered include files, contacts, events of smartphone and social network data storage and location. The smartphone examined produced abundant user information and in total 98,127 artefacts were recovered. Performing the extraction and analysis of digital evidence over smartphone activities show the possibility of identifying potential suspects that could assist the forensic investigators in crime investigations.
