디지털 매체의 증가로 인해 범죄의 상당한 부분이 디지털매체로 이루어지고 있다. 따라서 디지털 증거는 수사, 재판 과정에서 그 중요도가 점차 증가하고 있다. 그러나 형사소송법은 증거의 일반적인 규정만 하고 있을 뿐 디지털 증거에 관해서는 따로 규정하고 있지 않다. 또한 디지털 포렌식 절차에 대한 대부분의 연구는 범죄수사의 시간의 흐름에 따른 연구만 이루어질 뿐, 궁극적으로 법정에서 증거로 사용되기 위해 어떠한 절차를 따라야 하는지에 대한 연구는 이루어지지 않고 있다. 따라서, 현행 증거법에 맞게 디지털 포렌식 절차를 연구할 필요가 있다. 본 논문에서는 현행 증거법의 내용을 분석하고 현행 증거법에 적합한 디지털 포렌식 절차를 소개한다.

Based on the analysis of criminal investigators' recognition of judicial autopsy, this study presented policy alternatives as follows. First, a procedure is needed that optometrists and investigators jointly make previous explanations to bereaved families the status of investigation and the results of examination to their satisfaction and collect their opinions, for the purpose of obtaining an agreement to autopsy from them. Second, the dignity of the dead should be kept. To this end, particular consideration should be given to women bodies. Also, we need to minimize the number of autopsy witnesses and obtain agreement from bereaved families when there is an on-the-spot study. Third, we need to establish a guideline that investigators could request a warrant later in certain cases of dead bodies. Also, if a bereaved family positively asks for autopsy, it should be allowed through tentatively named ‘Request for Autopsy.’ Finally, To make a careful decision on whether an autopsy should be made or not, we can form a joint investigation team of public prosecutors and criminal investigators; however, an autopsy should be done only if it is deemed inevitable, considering the bereaved family's opinion.

The court in Korea values evidence justice, and also demands justification for the process of collecting evidence. Therefore, it is necessary to raise the level of organizational commitment, which means that the police investigators performing these tasks feel attached to the police organization they belong to, and that they feel united about the goals of the organization. Based on this recognition, the study analyzed the effects of the police's perception of organizational Justice on organizational commitment, and classified organizational Justice into distributive Justice, procedure Justice and interaction Justice. Therefore, this study analyzes the effect of the police's perception of organizational Justice on organizational commitment and verifies the effect through multiple regression analysis by injecting the trust of Supervisors into a mediating variable. The study was also conducted on the assumption that the trust of Supervisors is important in carrying out the field investigators work in the South Korean police. To achieve the purpose of this research, a total of three surveys were conducted from May 2017 to October 2019 at the National Police Agency using the selection process of investigators and job training courses for the national police, and a total of 500 copies were used as analysis data. Looking at the results analysis of this study, first, it was found that there was a statistically significant static (+) effect on organizational commitment, where the organizational Justice of police officers was a independent variable. Second, the relationship between organizational Justice and organizational commitment has shown that the trust of Supervisors has a mediating effect in korean police organization.

Cyber forensics is used the process and technology of digital forensics as a criminal investigation in cyber space. Cyber crime is classified into cyber terror and general cyber crime, and those two classes are connected with each other. The investigation of cyber terror requires high technology, system environment and experts, and general cyber crime is connected with general crime by evidence from digital data in cyber space. Accordingly, it is difficult to determine relational crime types, collect evidence and the legal admissibility of evidence. Therefore, we considered the classifications of cyber crime, the collection of evidence in cyber space and the application of laws to cyber crime. In order to efficiently investigate cyber crime, it is necessary to integrate those concepts for each cyber crime-case. In this paper, we constructed a cyber forensics domain ontology for cyber criminal investigation using the concepts, relations and properties, according to categories of cyber crime, laws, evidence, and information of criminals and crime-cases. This ontology can be used in the process of investigating of cyber crime-cases, and for data mining of cyber crime; classification, clustering, association and detection of crime types, crime cases, evidences and criminals.

Today, the international community make every effort to suppress security crimes, to provide numerous institutional strategies and to prevent security crimes such as the terrorism and spy. Particularly, developed countries in the field of security are strengthening related legislation under new-security conditions. Things work a little differently about security crimes because the nation's benefit and protection of the law is the basis of individual benefit and protection of the law under investigation procedure of the security crimes. Therefore they have policy that permits major investigative agency under the arrest and detention procedure(e.g. security and communication monitoring ${\ldots}$). Criminal procedure's improvement and reinforcement are very important for events related security. But, The investigation procedure between criminal offense and security crimes makes no odds in the Korea. Continuance of such a national mood will accuse of not responding appropriately in preparation for new-security conditions recently. To revise with international best security legislation, We should institute a proper registration system in Korea's situation. This study have been discussing how to improve related legislation under new-security conditions through the cases analysis of the arrest and detention procedure in Korea.

Right to counsel means a defendant has a right to have the assistance of counsel (i.e., lawyers), and if the defendant cannot afford a lawyer, requires that the government appoint one or pay the defendant's legal expenses. The right to counsel is generally regarded as a constituent of the right to a fair trial. Historically, however, not all countries have always recognized the right to counsel. The right is often included in criminal law and constitutional law etc. First, any person who is arrested or detained shall have the right to prompt assistance of counsel. When a criminal defendant is unable to secure counsel by his own efforts, the State shall assign counsel for the defendant as prescribed by act in article 12(4) of the constitutional law. Second, the defense counsel or a person who desires to be a defense counsel may have an interview with the defendant or the suspect who is placed under physical restraint, deliver or receive any documents or things and have any doctor examine and treat the defendant or the suspect in article 34 of the criminal law. Nonetheless, problems about guarantee of the rights to counsel to the national security violators like spy terrorist and etc will be important for Koreans to consider. That is because national security violators's cases are qualitatively different from general criminal offense's cases and historically, lawyer obstruct a investigation in the process of examination of a suspect for national security violators. Therefore, this study suggest a way that a restriction the rights to counsel with an attorney in cases of the national security violators. To this end, in this paper, I touch on restriction of right to counsel during interrogation in the England and Germany etc in comparison to that of Korea and review Korea's Supreme Court decision and Constitution Court decision to understand the prospective and trends for Korean investigation procedure improvement.

정보저장매체에 저장된 디지털정보로부터 범죄 단서를 찾고, 법정에 증거로 제출하기 위한 일련의 활동을 일컫는 디지털 포렌식의 개념과 기법이 국내 수사기관에 도입되어 활용된 지 10여년의 시간이 흘렀다. 그러나 디지털증거라는 새로운 개념의 탄생은 최근까지 정보의 압수대상 여부 논란 등 수사실무에서의 혼란을 초래하고 있다. 기존 증거와 구별되는 디지털정보의 특성으로 말미암아 증거로 활용함에 있어 필요한 별도의 절차적 기술적 조건이 요구되고 있으나, 과거 규정과 지침만으로는 디지털증거를 취급함에 있어 해석, 처리의 혼선을 가져 왔으며, 아직 명확하고 구체적인 실무 지침과 규정은 마련되지 못하고 있는 실정이다. 디지털증거 확보체계는 이러한 혼선을 최소화하기 위해 디지털증거의 증거능력 유지를 위해 필요한 최소한의 요건을 정의하고, 이를 바탕으로 법정 제출시까지 동일성, 무결성과 이를 증명하기 위한 보관연속성(Chain of Custody) 등을 유지 관리하기 위해 수사기관간에 구축하고 있는 인프라 시스템이다. 본 고에서는 수사기관간의 디지털정보, 디지털증거 처리, 유통, 취급에 있어 문제점을 살펴보고, 이를 보완 개선하기 위한 그간의 노력과 향후 발전방향에 대해 고찰해 보고자 한다.

When current cyber attacks to information and communication facilities are examined, technologies such as chase evasion technology and defense deviation technology have been rapidly advanced and many weak systems worldwide are often used as passages. And when newly-developed cyber attack instruments are examined, technologies for prefect crimes such as weakness attack, chase evasion and evidence destruction have been developed and distributed in packages. Therefore, there is a limit to simple prevention technology and according to cases, special procedures such as real-time chase are required to overcome cyber crimes. Further, cyber crimes beyond national boundaries require to be treated in international cooperation and relevant procedural arrangements through which the world can fight against them together. However, in current laws, there are only regulations such as substantial laws including simple regulations on Punishment against violation. In procedure, they are treated based on the same procedure as that of general criminal cases which are offline crimes. In respect to international cooperation system, international criminal private law cooperation is applied based on general criminals, which brings many problems. Therefore, this study speculates the procedural law on cyber crimes and presents actual problems of our country and its countermeasures.
