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.
利用 Android 智能手机设备的数字取证技术协助刑事调查
在过去十年中,全球数十亿用户成指数级地采用和拥有智能手机。然而,随着智能手机使用量的增加,犯罪分子也利用智能手机达到非法或犯罪目的。在刑事调查中,智能手机数据已成为宝贵的信息来源。本研究的重点是构建安卓操作的智能手机数据快照,以协助调查人员回答关键的调查问题。 将对有关在刑事案件中使用智能手机证据的文献进行全面审查,目的是强调调查阶段和移动数据证据在指导调查中的辅助作用。为了确定更多的相关人员并全面了解案件,该方法将包括分析用户配置文件、智能手机使用模式、通信日志、应用程序使用、地理查询和设备交互。通过对相关文献进行深入研究、设计合适的模型和开展案例研究,本研究旨在为创建时间轴或从智能手机数据中提取的可视化表述提供有价值的观点。本研究的结果将有助于提高移动取证在协助调查人员方面的效率,并促进将安卓操作的智能手机数据用作刑事调查的辅助证据。
