오늘날 인터넷 사용자의 급속한 증가와 데이터 중심의 무선 동신 기술의 빠른 성장으로, 중요한 정보를 비밀리에 전달하고자하는 보안성의 요구가 증가하고 있다. 무선인터넷은 데이터 공개성을 갖는 무선 매체를 사용한다는 점과 단말 혹은 사용자가 이동한다는 고유의 특성으로 인하여 제한된 CPU와 메모리 때문에 기존의 유선 PKI(Public Key Infrastructure)체계를 그대로 적용할 수 없는 기존 인터넷 보안 체계에 비해서 훨씬 복잡한 구조가 요구된다. [1] 본 논문에서는 이동하는 단말의 인증을 위한 효율적이고 유용한 식별자 적용기술인 스마트카드를 이용한 무선 인터넷 보안을 제공하기 위해 Mobile PKI 기반의 보안구조를 제안하여 보안을 강화하고자한다.

This study aimed to examine predictors of the intention to protect personal information on Facebook. We conducted an online survey of 679 Facebook users in the Republic of Korea. The findings of this study showed that usefulness and ease of use had significant effects on attitudes toward protection behavior. The results also revealed that risk factors (privacy risk severity and vulnerability) had significant effects on protective behaviors. Based on our findings, we discussed the information protection of privacy on Facebook.

Security is concerned with the protection of assets from threats, where threats are categorised as the potential for abuse of protected assets. All categories of threats should be considered, but in the domain of security greater attention is given to those threats that are related to malicious or other human activities ISO/IEC 15408 requires the TOE(Target of Evaluation) Security Environment section of a Protection Profile(PP) or Security Target(ST) to contain a list of threats about the TOE security environment or the intended usage of the TOE. This paper presents a specific physical threats should be considered in the smart card PP which developers of smart card PP must consider.

As the Internet use has been spreading worldwide, illegal and harmful contents have been increasing on the Internet, which has become a very serious social problem. To prevent children form exposing themselves to such illegal and harmful contents on the Internet, harmful information protection systems have been developed. We examine component technologies of harmful information protection systems including text and image-based filtering solutions as well as url-based filtering solution. Also we examine the related trends and strategies which effectively prevent access to the harmful contents.

After North American wide area black out on August 14, 2003, various studies have been conducted to find out the reason of the disaster. One of main reasons was misoperation of generator protection system. Since then, protective coordination between generator protection system and excitation system controls has been hot issue among electrical engineers. Among various generator protection relays, in this paper, we focused on generator overvoltage and overexcitation relay, which protect the over-flux condition of the generator. Thus, at first, we modeled the generator overvoltage, overexcitation relay and detailed power system including excitation system, governor and etc., based on actual field data. And then, we reviewed the protective coordination of generator overvoltage and overexcitation relay using electromagnetic transient program. In addition, we discussed the protective coordination method for redundant protection relays in both automatic voltage regulator and generator side.

European Union and United States have introduced new Privacy Shield agreement after decision of Court of Justice of the European Union which invalidated Safe Harbor agreement. Privacy Shield agreement contains several clauses to raise the level of personal data protection such as enhanced commitments, stronger enforcement, clear safeguards and transparency obligations, and effective protection of EU citizens' rights with several redress possibilities. This agreement has received positive response as an enhanced measure for personal data protection. This paper examines EU and US discussion history and current situation regarding Privacy Shield and suggests national policy direction such as measures for personal data transborder flow system improvement and international cooperation.

As the utilization value of personal information increases, discussions on how to provide personal information are active, but information required by institutions to utilize personal information is being exposed more than necessary. Therefore, personal privacy protection is essential to overcome the problems and limitations of personal information protection. In this study, a decentralized identity information management model that overcomes the problems and limitations of the centralized identity management method of personal information and manages and selectively provides personal information by the information owner himself and demonstrates the excellence of personal information by implementing the Smart Personal Information Provision System (SPIPS) in the PBFT consensus algorithm through experiments.

As a result of various personal information leakage incidents, the government implemented enhanced privacy protection measures, and financial companies are making efforts to periodically check whether personal information is misused according to government measures, but the problem of misuse of personal information is still not improved. The purpose of this study is to analyze the results of field experiments using the monitoring system for misuse of personal information and to suggest ways to improve the misuse problem. Based on the specific deterrence theory, this study examined the effects of misuse prevention according to the method of dealing with misusers, and analyzed the relationship between the duties of misusers and their years of service and misuse. It is expected that the analysis results of this study will be used for effective policy establishment.

Objective: The purpose of this study was to analyze the operation and personal information management of public and private kindergarten homepages. Methods: A total of 2,846 kindergartens were selected from the I-Sarang portal service for analyzing operation, and 217 self-operating homepages were selected for evaluating management. Seven evaluation items from three domains (information gathering procedures and scope, information security, and management of file exposure protection) were used. Wireshark and Google were used for analyzing some evaluation items. Results: The operating ratio of kindergarten homepages was low and most of the kindergartens self-operated their homepages. The evaluation of the information gathering procedures and scope showed that the rule of consent process was not rigidly followed but that the rule of legality for information gathering was followed. Items related to information security were followed at very low levels. As for the management of file exposure protection, the evaluation of items related to the prevention of attachment disclosure showed that the rule of protecting personal information included in an attached file was followed but that the notice regarding information protection was not. Across all evaluation items, the level of personal information management was higher in public (vs. private) kindergartens. Conclusion: These results indicate methods to more securely and effectively manage personal information on kindergarten homepages.

Precision Medicine, which utilizes personal health information, genetic information, clinical information, etc., is growing as the next-generation medical industry. In Korea, medical institutions and information communication companies have coll aborated to provide cloud-based Precision Medicine Hospital Information Systems (P-HIS) to about 90 primary medical ins titutions over the past five years, and plan to continue promoting and expanding it to primary and secondary medical insti tutions for the next four years. Precision medicine is directly related to human health and life, making information protecti on and healthcare information protection very important. Therefore, this paper analyzes the preliminary research on inform ation protection models that can be utilized in cloud-based Precision Medicine Hospital Information Systems and ultimately proposes research on ways to improve information protection in P-HIS.
