Acquiring a clear perspective of events and artefacts that occur over time is a challenging objective to accomplish in digital forensics. Reconstruction of the timeline of events and artefacts, which enables digital investigators to understand the timeline of digital crime and interpret the conclusion in the form of digital evidence, is one of the most paramount and challenging tasks in digital forensics. This challenging task requires the analysis of immense amounts of events because of the explosive growth of the internet, interconnected devices, and innovative technology nowadays. Various approaches have been developed during the last decade, but most of them are not able to handle huge volumes of data, explore evidence, and enhance the understandability of timelines in a competent way to assist the investigator. For this purpose, we introduce a methodology backed by an abstraction concept and forensic tools that can support investigators during the reconstruction, understanding of the timeline of events and artefacts, and interpretation of evidence by tracing the activities performed by users of the typical computer system. The Java programming language is used to implement the proposed methodology, which is object-oriented and follows the symmetry definition in software. Generally, symmetry in software can be viewed as an invariant change that aims to preserve a specific property of the system, namely its structure, behaviour, regularity, similarity, familiarity and uniformity. Similarly, the abstraction-based methodology also permits us to follow the properties of symmetry. For instance, a uniform structure is stipulated for all the sources at the particular level of abstraction, such as the number of fields to be considered to provide the abstract level of timeline. The primary purpose of this approach is to assist with the analysis of the timeline in an optimum way. This paper illustrates the approach and then focuses on conceptual aspects of the methodology. The performed experiment shows that the proposed approach enhanced the analysis of the timeline.

Original Information

Steganography is one of the anti-forensic techniques that allow criminals to hide information in other messages so that during the investigation, the investigator will experience problems and difficulty in getting evidence of original information on the crime. Therefore an investigator is required to have the ability to be able to find and extract (decoding) using the right tools when opening messages that have been inserted by steganography techniques. The purpose of this study is to analyze digital evidence using the static forensics method by applying the six stages to the Digital Forensics Research Workshop (DFRWS) framework and extracting steganography on files that have been compromised based on case scenarios involving digital crime. The tools used are FTK Imager, Autopsy, WinHex, Hiderman, and StegSpy. The results of extraction of 9 out of 10 files that were scanned by steganography files had 90% success and 10% of steganography files were not found, so it can be concluded that the extraction files in steganographic messages can be used as legal digital proofs according to law.

The Brain

The prevalence of mobile phone addiction (MPA) has increased rapidly in recent years, and it has had a certain negative impact on emotions (e.g., anxiety and depression) and cognitive capacities (e.g., executive control and working memory). At the level of neural circuits, the continued increase in activity in the brain regions associated with addiction leads to neural adaptations and structural changes. At present, the spontaneous brain microstates that could be negatively influenced by MPA are unclear. In this study, the temporal characteristics of four resting-state electroencephalogram (RS-EEG) microstates (MS1, MS2, MS3, and MS4) related to mobile phone addiction tendency (MPAT) were investigated using the Mobile Phone Addiction Tendency Scale (MPATS). We attempted to analyze the correlation between MPAT and corresponding microstates and provide evidence to explain the brain and behavioral changes caused by MPA. The results showed that the total score of the MPATS was positively correlated with the duration of MS1, related to phonological processing and negatively correlated with the duration of MS2, related to visual or imagery processing, and MS4, related to the attentional network; the score of the withdrawal symptoms subscale was additionally associated with duration of MS3, related to the cingulo-opercular emotional network. Based on these results, we believe that MPAT may have some negative effects on attentional networks and sensory brain networks; moreover, withdrawal symptoms may induce some negative emotions.
