Although the various crime involved numerous digital evidence, the digital evidence is hard to be acknowledged as a evidence to proof the crime fact in court. We propose the method of verification for the legal admissibility of digital evidence using digital forensics ontology. In order to verify the legal admissibility of digital evidence, we will extend the digital ontology by standard digital forensics process from Digital Forensics Technical Manual defined by KNPA and set up the relation properties and the rule of property constraint to process class in the digital forensics ontology. It is possible for proposed ontology to utilize to plan the criminal investigation and to educate the digital forensics.

Over the past decade, law enforcement organizations have been dealing with the development of cybercrime. To address this growing problem, law enforcement organizations apply various digital forensic (DF) tools and techniques to investigate crimes involving digital devices. This ensures that evidence is admissible in legal proceedings. Consequently, DF analysts may need to invest more in proprietary DF hardware and software to maintain the viability of the DF lab, which will burden budget-constrained organizations. As an alternative, the open source DF tool is considered a cost-saving option. However, the admissibility of digital evidence obtained from these tools has yet to be tested in courts, especially in Malaysia. Therefore, this study aimed to explore the admissibility of digital evidence obtained through open source DF tools. By reviewing the existing literature, the factors that affect the admissibility of the evidence produced by these tools in courts were identified. Further, based on the findings, a conceptual framework was developed to ensure the admissibility of the evidence so that it will be accepted in the court of law. This conceptual framework was formed to outline the factors affecting the admissibility of digital evidence from open source DF tools, which include; 1) The Availability and Capability of open source DF tools, 2) the Reliability and Integrity of the digital evidence obtained from open source DF tools, 3) the Transparency of the open source DF tools, and 4) the Lack of Reference and Standard of open source DF tools. This study provides valuable insights into the digital forensic field, and the conceptual framework can be used to integrate open source DF tools into digital forensic investigations.

This study aimed to analyze the quality concepts and requirements of digital records as evidence and to find an implication to develop requirements for trusted digital records with securing authoritative qualities. To this end, this study compared requirements of records domain linking records process, records metadata and records systems with judicial domain on digital evidence, and identified the records requirements to secure the legal admissibility linking records and judicial domain. This study analyzed the relationship of quality concepts between digital records and digital evidence, found the legal admissibility is highly related to the reliability, and derived that it needs the measure to secure the reliability at the stage of records creation and capture. To prove authenticity of digital evidence, this study identified importance of records process, records metadata and records system, and proposed the necessity of measurement to secure records' evidence.

As many companies are considering to use server virtualization technology to reduce cost, the crime rates in virtual server environment are expected to be increasing rapidly. The server virtualization solution has a basic function to produce virtual machine images without using any other disk imaging tools, so that investigating virtual servers are more efficient because the investigator only has to collect the virtual machine image and submit it to the court. However, the virtual machine image has no admissibility to be the legal evidence because of security, authenticity, procedural problems in collecting virtual machine images on virtual servers. In this research, we are going to provide requirements to satisfy security, authenticity and chain of custody conditions for the admissibility of the virtual machine image in server virtualization environment. Additionally, we suggest definite roles and driving plans for related organizations to produce virtual machine image as a admissible evidence.

With the development of information and communication technology, various data including digital data have increased exponentially. In a society where such data utilization is generalized, criminal investigation processes and trial processes have also been influenced. However, in comparison with the progress of the technical capability and analytical capability of digital certification which is increasing exponentially, the establishment of the digital forensic related legal system is still in short supply. Therefore, it is necessary to activate balanced research for legal recognition of digital certification. Therefore, in this research, meta analysis was conducted to grasp trends of research related to digital forensics and to provide objective data for research revitalization.

Recently, digital imaging is frequently used by crime scene investigators. However, the admissibility of digital photographic evidence in court is often raised because of the fact that digital photographs are more easily modified than film-based photographs. Therefore, in this article, the researcher reviewed some basic theories and legal considerations related with police crime scene investigations in Korea and The United States. This article is presented in the hope of clearing up some of the possibilities of falsifying photographic evidences and in the hope of setting the strict the rules of evidence regarding digital evidence in this county.

In 2012, the major jurisdictions regarding medical cases caused the controversial issues towards medical and legal fields by getting the judgments from the Supreme Court, which admitted the exceptional admissibility on discretionary grant. By regarding the serial negligence of medical organizations as a separate tort, the sentences which made up irrationality, were spoken by the court. As a result, if the treatment was made, which did not follow the entered matters in medical documents attached, the court announced the jurisdiction that presumes the negligence, which provided the evidence of negligence; on the other hand, this gave had the burden to medical branch to take great care for medicinal treatment. To be applicable for the Principle of Trust, the doctors have to give and take the necessary information for the treatment process and symptom decisions, which also commented in the court. Thus, this case made it difficult to apply the Principle of Trust and considered all the conditions as tough ones, which eventually induced lesser faults for patients' care. Moreover, the court confirmed that the medical ads sending the emails to the members belong to the internet portal sites, are not the inducing behavior by considering that the actions are only medical ads. Furthermore, in the case of Namsu Kim, the court's interpretation was rather limited the definition for medical practice that announced limited Erweiterung der Strafbarkeit cases by lower courts. As a consequence, it is very interesting whether the Supreme Court may change their position and concerning the duty of explanation, the trend to expand the contents and scopes for the duty of explanation continues by admitting instruction explanation obligation and all the compensations and so on.

This study aims to develop the trustworthiness model for public digital records, as an admissibility framework for establishing trust. The trustworthiness model is deemed to used to identify the qualities of the digital records in their lifecycle, including the identity that could be identified at the time of the creation, integrity obtained from the chain-of-custodial management, the evidence of relationship between business activities and records, and the technical or cognitive accessibility. Based on the analysis of the QADEP model, it was decided to develop a model that could measure the trustworthiness of public digital records in the external measurement type, which are authenticity, reliability, and usability. In line with this direction, the model expanded measurement areas and indicators of the QADEP model through the analysis of ISO 16175-1:2020, and measuring metrics was also proposed so that it could be a measuring instrument for public digital records in Korea, after analysing NAK 19-3. It would be useful to expand the model and to test the approach of the trustworthiness model for public digital records.
