Abstract

Email is an imperative method of communication that is changing the way people share their data and information. It provides effective and efficient communication, especially in business, convenience, and easy access and replication. Those electronic data should be considered by a fraud investigator to comprehend the investigation. Email can be divided into two parts: the head of the email and the email body. The head of the email is metadata that consists of unstructured data, and the body and its attachment consist of semi-structured data. The email data usually comes in large volumes and ranges of types. Therefore, a manual investigation of an email should be avoided. This paper uses the Design Science Research Methodology to discover the most profound framework in an email fraud investigation. Using email metadata and email body, this research performs a digital forensic framework: preparation, gathering, processing, and presentation, combines with social network analysis to be applicable in the investigation. The result shows that digital forensics process, network analysis, data visualization provides a more valuable and comprehensive insight into email analysis.

Abstract

Digital evidence has become increasingly important in corruption investigations; however, its quality and utilization vary significantly across Indonesia’s judicial system. This study examines how digital evidence influences anti-corruption justice by analyzing institutional capacity, forensic quality, and regional disparities. Using a mixed-methods approach combining quantitative analysis of 1,248 court decisions from 2010–2023 and qualitative document analysis, this study identifies patterns in digital evidence adoption and forensic procedures. The findings reveal a dual-track system in which corruption cases demonstrate substantially higher forensic compliance than other case categories, while significant disparities exist between Jakarta and regional courts. The study argues that legal frameworks alone are insufficient to ensure consistent digital evidence practices, as institutional capacity and resource distribution play critical roles. This research contributes by proposing a reform framework emphasizing tiered standards, regional forensic capacity development, specialized task forces, and procedural improvements.
