Using Digital Forensics for Android Smartphone Devices to aid Criminal Investigations

Abstract

In the past decade, there has been an exponential adoption and ownership of smartphones by billions of users worldwide. However, as smartphone usage increases, criminals have taken advantage of them for illicit or criminal purposes. In criminal investigations, smartphone data has become an invaluable source of information. This study focuses on constructing a snapshot of Android-operated smartphone data to assist investigators in answering critical investigative questions. A thorough review of the literature with regard to the use of smartphone evidence in criminal cases, with the goal of emphasising the investigative phase and the supportive role of mobile data evidence in guiding investigations will be performed. In order to identify additional persons of interest and develop a thorough understanding of the case, the methodology will entail analysing user profiles, smartphone usage patterns, communication logs, application usage, geographic lookups, and device interactions. By conducting a thorough examination of relevant literature, designing a suitable model, and executing a case study, the study intends to offer valuable perspectives on the creation of timelines or visual representations derived from smartphone data. The results of this study will contribute to improving the efficacy of mobile forensics in assisting investigators and facilitating the use of Android-operated smartphone data as supporting evidence in criminal investigations.
