In most hacking attacks, hackers tend to access target systems in a variety of circumvent connection methods to hide their original IP. Therefore, finding the attacker's IP(Internet Protocol) from the defender's point of view is one of important issue to recognize hackers. If an attacker uses a proxy, original IP can be obtained through a program other than web browser in attacker's computer. Unfortunately, this method has no effect on the connection through VPN(Virtual Private Network), because VPN affects all applications. In an academic domain, various IP traceback methods using network equipments such as routers have been studied, but it is very difficult to be realized due to various problems including standardization and privacy. To overcome this limitation, this paper proposes a practical way to use client's network configuration temporarily until it can detect original IP. The proposed method does not only restrict usage of network, but also does not violate any privacy. We implemented and verified the proposed method in real internet with various VPN tools.

To provide visitors with the various services, Many web sites distribute many ActiveX controls to them because ActiveX controls can overcome limits of HTML documents and script languages. However, PC can become dangerous if it has unsecure ActiveX controls, because they can be executed in HTML documents. Nevertheless, many web sites provide visitors with ActiveX controls whose security are not verified. Therefore, the verification is needed by third party to remove vulnerabilities in ActiveX controls. In this paper, we introduce the process and the technique to fad vulnerabilities. The existing proof codes are not valid because ActiveX controls are different from normal application and domestic environments are different from foreign environments. In this paper, we introduce the technique to prove vulnerabilities in ActiveX control.

This paper analyzes the attack method of pastejacking and proposes a clip toaster that can effectively defend it. When programming, developers often copy and paste code from GitHub, Stack Overflow, or blogs. Pastejacking is an attack that injects malicious data into the clipboard when a user copies code posted on the web, resulting in security threats by executing malicious commands that the user does not intend or by inserting dangerous code snippets into the software. In this paper, we propose clip toaster to visualize and alertusers of threats to defend pastejacking that threatens the security of the developer's terminal and program code. Clip Toaster can visualize security threat notifications and effectively detect and respond to attacks without interfering with user actions.

Records related to a certain cultural heritage are concrete evidence that prove the value of the cultural heritage and become a criterion for long-term preservation of its records. The value of the records is as important as cultural heritage value. In the case of specific cultural heritage with national or socially important values, various studies are conducted on cultural heritage as one theme, and various programs about cultural heritage are developed. However, it is difficult to grasp the scope, record types, and contents of the records because they have been distributed and managed in many institutes. They also appear in various forms. As a solution to these problems, this study collected records of a major cultural heritage with social and historical values such as Hwangnyongsa from 11 public institutions and web services and analyzed the types of records, activities related to the records, and metadata. Through data analysis, an ontology that can understand the range and relationship of the entire record was suggested so that the record can be understood with a focus on specific cultural heritage.

Clinical nomogram is a graphical representation of numeric formula, constructed from clinical cases database of followed patients' treatment, which is used for medical predication. For a clinical nomogram to contribute patient care, it is required to accumulate as many as clinical cases and to extract medical prediction knowledge. It needs to be equipped with an effective method to build medical nomogram with high predication accuracy. It is desirable for medical nomogram to be accessible at patient care point. This paper proposes a medical nomogram service system architecture which takes into account the above-mentioned issues. The proposed system architecture includes a web-based database subsystem to maintain and keep track of clinical cases. On the periodic basis, a new clinical nomogram is reconstructed for the updated clinical database. For the convenient use of patient care practice environment, an app-based program is provided which makes prediction based on the most recent clinical nomogram constructed in the service system. The proposed method has been applied to a clinical nomogram service system development for recurrence and survival prediction in bladder cancer patients.
