ACQUISITION AND PRESENTATION OF DIGITAL EVIDENCE IN CRIMINAL TRIAL IN INDONESIA

Digital evidence is not included in the types of evidence as stipulated in Article 184 paragraph (1) of the Criminal Procedure Code, but is regulated in Law No. 11 of 2008 concerning Electronic Information and Transactions as amended by Law No. 19 of 2016. However, it is often found that the submission of digital evidence is not only for criminal cases related to electronic information and transactions, but also for criminal cases that are not regulated in the Law on Electronic Information and Transactions. Furthermore, distinct characteristics of digital evidence compared to evidence in general require different acquisition and presentation method. Hence the writers intends to examine the method of acquisition and presentation of digital evidence in criminal trial and how judges evaluate digital evidence by examining how it was obtained and presented to the trial. This research is normative legal research, where the data sources include research on legal principles, legal system, and legal comparison. From the research, it was concluded that Indonesia already has laws and regulations governing the expansion of evidence to include digital evidence, Indonesia also has rules regarding the method of acquisition and presentation of digital evidence in the criminal trial. Therefore, judges are required to be able to evaluate the validity of digital evidence by observing the method of acquisition and presentation of digital evidence in the criminal trial based on applicable laws.

Digital Integrity

Abstract Researchers working with digital evidence must be aware of its vulnerabilities if they hope to maximize its value for justice and accountability. In this paper, we highlight two important vulnerabilities: the impermanent nature of digital evidence, and its susceptibility to attack from online dis/misinformation campaigns. We argue that to overcome the challenge that the impermanent nature of digital evidence presents, researchers can implement rapid response archiving techniques that, while not as rigorous as protocols set out for the collection of evidence in legal cases, could leave them with digital breadcrumbs to aid with the recovery of deleted digital evidence. We further propose that researchers consider implementing a stance of radical transparency in the collection, synthesis, and presentation of digital evidence with the goal of fortifying it against dis/misinformation campaigns.

A Survey on Digital Forensic Investigation Practitioners Approach and Challenges

Digital crimes are taking place over the entire world. For any digital crime which commit at any part of world, computer or any electronic devices are used. The devices which are used to commit the crime are useful evidences which must be identified and protected for further use. The crimes involving electronic devices are called as cyber-crime. To investigate such crimes, a scientific procedures needs to be followed. The data collection, analysis, preservation and presentation of digital evidence is must in order investigate the cybercrime. This paper highlights the practices that are used worldwide in the investigation process of cyber-crime. Keywords: Digital Forensics, Analysis, Investigation, models of investigation.

Comparative Study and Analysis on Integrity of Data Files Using Different Tools and Techniques

Digital forensic investigation is the scientific process of collection, preservation, examination, analysis, documentation and presentation of digital evidence from digital devices, so that the evidence is in compliance with legal terms and acceptable in a court of law. Integrity of the digital evidence is an indispensable part of the investigation process and should be preserved to maintain the chain of custody. This is done through hashing technique using standardized forensic tools. However, while handling the evidences , lack of knowledge might lead to unintentional alteration of computed hash. This violates the chain of custody and makes the evidence inadmissible in a court of law. In this paper, our objective is to determine the different conditions under which the original hash value of a digital evidence changes. For this, we create different scenarios using sample data files and compute their hash values. A comparative study and analysis are done to determine in which scenario the original hash value of the data file changes. The results of the research will prove useful and essential for Criminal Justice Functionaries in gaining knowledge about various conditions leading to the change in hash value of digital evidence and therefore, avoid its accidental alteration during forensic investigation/examination.

Applying Digital Forensics to Service Oriented Architecture

Digital forensics is an emerging research field involving critical technologies for obtaining evidence in digital crime investigations. Several methodologies, tools, and techniques have been developed to deal with the acquisition, preservation, examination, analysis, and presentation of digital evidence from different sources. However, new emerging infrastructures such as service-oriented architecture has brought new serious challenges for digital forensic research to ensure that evidence will be neutral, comprehensive, and reliable in such complex environment is a challenging research task. To address this issue, the authors propose in this article a generic conceptual model for digital forensics methodologies to enable their application in a service-oriented architecture. Challenges and requirements to construct a forensically sound evidence management framework for these environments are also discussed. Finally, the authors show how digital forensics standards and recommendations can be mapped to service-oriented architecture.

New Model for Cyber Crime Investigation Procedure

In this paper, we presented a new model for cyber crime investigation procedure which is as follows: readiness phase, consulting with profiler, cyber crime classification and investigation priority decision, damaged cyber crime scene investigation, analysis by crime profiler, suspects tracking, injurer cyber crime scene investigation, suspect summon, cyber crime logical reconstruction, writing report. Computer forensics emerged in response to the escalation of crimes committed by the use of computer systems either as an object of crime, an instrument used to commit a crime or a repository of evidence related to a crime. Computer forensics can be traced back to as early as 1984 when the FBI laboratory and order law enforcement agencies begun developing programs to examine computer evidence. Digital forensics has been defined as the use of scientifically derived and proven methods towards the preservation, collection, validation, identification, analysis, interpretation and presentation of digital evidence derived from digital sources for the purpose of facilitating or furthering the reconstruction of events found to be crime or helping to anticipate the unauthorized actions shown to be disruptive to planned operations. Digital evidence includes computer evidence, digital audio, digital video, cell phones, digital fax machines etc. The U.S. Department of Justice published a process model in the Electronic Crime Scene Investigation: A guide to first responders that consists of four phases: collection, examination, analysis, reporting. The analysis phase of this model is improperly defined and ambiguous. Brian Carrier (5) proposed integrated digital investigation process. It (5) was consisted of 5 phase like readiness phase, deployment phase, physical crime scene investigation phase, cyber crime scene investigation phase, review phase. The Brian Carrier (5) procedure didn't include which classifying cyber crime and deciding investigation priority, psychological profiling investigation method, and so on. In this paper, we presented a new model for cyber crime investigation procedure. The proposed procedure model is as follows readiness phase, consulting with profiler, cyber crime classification and investigation priority decision, damaged cyber crime scene investigation, analysis by crime profiler, suspects tracking, injurer cyber crime scene investigation, suspect summon, cyber crime logical reconstruction, writing report. This paper presented a new methodology of a digital forensic investigation procedure. Section 2 shows previous cyber crime investigation model. We present our method for cyber crime investigation procedure model in section 3.

Memory-Based Antiforensic Tools and Techniques

Computer forensics is the discipline that deals with the acquisition, investigation, preservation, and presentation of digital evidence in the court of law. Whereas antiforensics is the terminology used to describe malicious activities deployed to delete, alter, or hide digital evidence with the main objective of manipulating, destroying, and preventing the creation of evidence. Various antiforensic methodologies and tools can be used to interfere with digital evidence and computer forensic tools. However, memory-based antiforensic techniques are of particular interest because of their effectiveness, advanced manipulation of digital evidence, and attack on computer forensic tools. These techniques are mainly performed in volatile memory using advanced data alteration and hiding techniques. For these reasons memory-based antiforensic techniques are considered to be unbeatable. This article aims to present some of the current antiforensic approaches and in particular reports on memory-based antiforensic tools and techniques.
