검색 가능 암호 시스템은 암호화된 자료를 복호화하지 않은 상태에서도 원하는 자료를 검색할 수 있도록 하는 암호기반 기술이다. 정보를 암호화하여 저장하는 기법은 데이터베이스 보안을 위한 핵심 기술 가운데 하나로 각광받고 있지만, 암호화를 통한 보안성 확보는 데이터베이스의 검색 속도를 현저히 저하시키는 문제를 야기한다. 검색 가능 암호 시스템은 이러한 문제의 해결 방안 중 하나로 주목받고 있으며, 학계를 중심으로 많은 연구가 진행되고 있는 상황이다. 본 고에서는 이제까지 발표되었던 중요한 검색 가능 암호 기술에 대해 살펴보기로 한다.

This research focuses on the perception of security screeners using a full body scanner at airport which had been newly introduced to terminal 2 of Incheon Int'l airport. To accomplish the purpose of research, this paper used UTAUT (Unified Theory of Acceptance and Use of Technology) model. Through an empirical analysis, it was proven the factors consisting of technological acceptance and how those factors affect both organizational innovation at airport and job satisfaction of security screeners. According to an empirical analysis, it was found out all the factors of technological acceptance have a significant effect on both organizational innovation and job satisfaction. However, only the effort expectation was shown to have a significant negative effect on the two dependant variables contrary to the other variables (performance expectation, behavioral intention and self efficacy. It was also proven organizational innovation had a moderating effect between technological acceptance and job satisfaction. Such results suggested organizational innovation at airport security division is necessary to enhance job satisfaction using a newly introduced full body scanner.

Countries across the globe, including those in Europe, are waging a "war against terrorism" as international terrorist groups such as ISIS and lone-wolf terrorists have unleashed various large-scale attacks on rail infrastructure. Anti-South Korean sentiment exists in Muslim-majority countries because the nation has cooperated with the US for its military interventions in the Middle East, and ISIS has threatened to target South Korea four times since September 9, 2015. In addition, North Korea has been left isolated in the international community with its missile and nuclear tests, while further escalating inter-Korean tension and threatening to strike major facilities and attack important figures in the South. These situations imply that South Korea is no longer immune to terrorist attacks. If the nation fails to prevent or deter such terrorist attacks against rail networks, massive casualties, property damage and social confusion would be unavoidable, deteriorating national and international trust in its counter-terrorism policies. This may lead to a national crisis involving decreases in the number of tourists, dampened interest of foreign investors, and capital flight. This study aims to propose policy measures to enhance railroad security checks, based on the work of railroad police officers, for the sake of protecting citizens and public safety. The suggestions include an incremental expansion of railroad security checks; growth of the railroad police force and adjustment of their policing distribution with other police officers; enhancement of security systems across important rail networks; improvement of the Railroad Safety Act; Southeast Asia, including the corresponding strengthening of the national crackdown illegal immigrants, and plans for pre-emptive and regular cooperation among organizations related to the promotion of security checks and the prevention of terrorist attacks.

악의적 목적을 가진 Hacker는 Google의 검색 기능과 키워드 사용을 이용해 인터넷 상에 존재하는 개인정보를 탈취하거나 웹페이지의 취약성, 해킹 대상에 대한 정보들을 수집할 수 있다. Google의 검색 결과 인터넷에서는 수많은 개인정보가 검색되고, 이중에는 타인에게 노출되지 않아야 하는 개인의 이력서, 기업의 기밀자료, 관리자의 ID, Password 등도 인터넷 상에서 보안되지 않은 상태로 존재하고 있다. 본 논문에서는 Google을 이용한 정보검색과 정보탈취에 대해 연구하고, 개인 탈취 정보를 이용한 침해사고와 포렌식 자료 생성에 관한 기술과 보안방안을 제안한다. 본 논문 연구를 통하여 인터넷 검색 결과에 대한 보안 취약성 보완의 기술 발전과 기초자료로 활용될 것이다.

The purpose of this study verify to the effect of applying the X-ray screening ability rating for security screening persons in Incheon International Airport. Data collected through a evaluation score of 1,034 security screening persons in Incheon International Airport. Data analysis performed using paired sample t-test. The research results found that it was a statistically significant difference pre-test and post-test applying the X-ray screening ability rating. In this article, we asserts that the X-ray screening ability rating is effective in improving the X-ray screening ability of security screening persons. This paper contribute to the academic expansion of motivation theory and self-determination theory. This study is valuable as a preemptive empirical research that provides practical implications about the application of X-ray screening ability rating for security screening persons.

Since 2006, social networking services such as Facebook, Twitter, and Blog user increasing very rapidly. Furthermore demand of Book Retrieval Service using smartphone on social network service environment are increasing too. This service can to easy and share information for search book and data in several university. However, the current edition of the social services in the country to provide security services do not have the right. Therefore, we suggest a social book Retrieval service in social network environment that can support user authentication and partial filter search method on smartphone. our proposed system can to provide more speed responsiveness, effective display result on smartphone and security service.

Smart Security is the global initiative of Airports Council International in collaboration with airports, airlines and governmental agencies. Its main objective is to create a step change in passenger and cabin baggage screening, escalating security costs and constantly evolving threats. Incheon International Airport should adopt and deploy smart security systems not only to strengthen aviation security but also increase passenger's experiences and operational efficiency by way of seamless security screening that it will lead to establish the best security environment to prevent terrorism and acts of unlawful interference.

An increasing in quantity of multimedia data brought a new problem that expected data should be retrieved fast and exactly. The adequate representation is a key element for the efficient retrieval. For this reason, MPEG-7 standard was established for description of multimedia data in 2001. In this paper, we designed a Audio/Image Retrieval System based on MPEG-7 that can retrieve multimedia data like audio, image efficiently. And we integrated high-level and low-level schemas to retrieve datas for users.
