  • 최근들어 보험사기로 인한 피해가 날로 극심해지고 있다. 이러한 보험사기로 인한 피해를 예방하고 억제하기 위해 오랜시간 논의를 해왔으며, 결국 보험사기방지 특별법을 제정하여 2016. 9. 30. 시행하였다. 그러나 단지 이러한 특별법 시행만으로는 보험사기로 인한 폐해를 완전히 해결할 수 없다. 따라서 특별법 시행으로 인한 현실적인 보험사기 억제효과를 살펴보고 이에 대한 문제점을 분석하여야 한다. 이에 본 연구에서는 보험사기방지 특별법 시행으로 인한 효과에 대하여 현실적으로 살펴보고, 이에 대한 문제점을 모색한 후 개선방안을 제시해 보고자 한다.

  • Recently, new light curing unit utilizing the plasma xenon arc lamp is introduced. This curing unit is operated at relatively high intensity, so shortening the curing time significantly. The aim of this experiment was to estimate curing capability of plasma xenon arc lamp curing unit compared to traditional halogen lamp curing unit. Degree of conversion was evaluated by Raman spectroscopy after irradiation of specimens with halogen lamp curing unit(Optilux 150, Demetron, USA) for 20s, 40s, 60s and plasma xenon arc lamp curing unit(flipo, Lokki, France) for 2s, 3s, 6s. The results showed that strong light intensity of plasma xenon arc lamp curing unit did not compensate for short exposure time completely. So, Multi-layered curing within 2mm thickness and additional exposure time is recommanded when light-cured composite resin is polymerized with plasma xenon arc lamp curing unit.

  • Recently, proving insurance fraud has become increasingly difficult because it occurs intentionally and secretly via organized and intelligent conspiracy by specialists such as medical personnel, maintenance companies, insurance planners, and insurance subscribers. In the case of car accidents, it is difficult to prove intentions; in particular, an insurance company with no investigation rights has practical limitations in proving the suspicions. This paper aims reveal that the detection of organized and conspired insurance fraud, which had previously been difficult, could be dramatically improved through conspiring insurance fraud detection modeling using social network analysis and visualization of the relation between suspected group entities and by seeking developmental research possibilities of data analysis techniques.

This paper aimed to suggest a direction for improvement of the EFFPS, through the analysis of electronic financial fraud cases. As a result of analysis on the fraud cases before and after implementation of the EFFPS, 'Fraud using Smartphone App' and 'Fraud using Calls and SMS' were increased after implementation of the EFFPS, and also the damage cost of 'Fraud using Smartphone App' had increased. Also we revealed some limitations of the EFFPS. For complementing this limitations, authors considered direction for improvement of the EFFPS focus on application of current services/systems related prevention of electronic financial fraud and considered the ways that are make connection with several measurements related prevention currently being discussed and implemented in perspective of defense in depth.

  • As the number of recent information security incident occurrence increases, more and more workload and liability pressure are given to info-security professionals, which results in decrease of morale level of working groups in the field. In order to solve this problem, Korean government is providing various action plans to improve the morale level of info-security professionals, and also requiring financial companies to submit its own action plan of increasing morale of info-security professionals to Financial Service Agency. For this study, based on the previous studies and relevant professionals' interviews, we selected 16 critical morale increase variables, and performed survey for empirical analysis. As a result, 3 features; role, system, and relationship were presented as the main factor of morale increasement of info-security professionals. This study also suggests a decision making method of utilizing the developed morale measurement model for individual organizations.

  • Recently, much attention in electronic financial fraud has been dramatically increased. In particular, the electronic financial fraud has been transforming to social engineering. Despite the growing interest in electronic financial fraud, few guidelines exist how to effectively avoid the serious damage from electronic financial fraud. Moreover, it is rarely investigated cases of victims from financial fraud. Therefore, the purpose of this study is to investigate why financial fraud crime victims occurs. To enhance mundane realism, we conducted Focus Group Interview(FGI) with actual victims from financial fraud crime. Drawing analysis of FGI with actual victims, we found that there are certain damage patterns. Further, we found that the reason why financial fraud crime victims occurs is optimistic biases of humans rooted in behavioral economics. Therefore, this study provides the valuable guidelines and directions to prevent electronic financial fraud based on risk and crisis management perspective. Ultimately, this study is able to help the establishment and implementation of a comprehensive electronic financial fraud prevention policy.

  • The purpose of this study is to empirically and practically verify the applicability of visualization data mining tool in detecting real-word insurance frauds that are now emerged as one of the most serious problems socially and economically. For the verification, Analyst's Notebook by i2, which has been known as the most effective visualization data mining tool, was adopted. With Analyst's Notebook, fraud-probable insurance transactions from a very large insurance claims are selected and then substantiation for insurance frauds are attempted. The results show that Analyst's Notebook not only detects insurance fraud transactions from a vast number of insurance claims, but is also able to pinpoint organized crime group by associating one fraud transaction to another fraud transaction. Therefore, it is safe to conclude that visualization data mining is very effective in detecting false transactions and crime behaviors including insurance fraud.

  • This paper analyzes insurance crimes using a game theoretic model. In blackmailing cases involving automobile accidents, insurance criminals deliberately induce innocent drivers(victims) to commit a moving violation such as crossing over the center dividing yellow line, and collide with the victims. After the collision, the criminals and the victims effectively engage in a bargaining game over the amount of the settlement for the damage. Because the penalty for that kind of moving violation is very severe (even criminally prosecuted), the victims do not have much bargaining power. Exploiting the weak bargaining power of the victims, the criminals demand and receive huge compensation (including settlement) from the victims. In the model, it is shown that under the current law agents have perverse incentives leading to insurance crimes. The criminals have incentive to induce car collisions and extract huge settlement from the victims. Based on the analysis, it is suggested that lowering the severity of penalty for certain kind of violation may be needed to prevent insurance crimes, in addition to increasing the crime investigation activities and strengthening punishment for insurance criminals.
