We have developed a new remote-configurable firewall system that provides secure and easy-to-use access to home-network appliances such as network cameras, PVRs, and home file servers, through the internet. With a simple web browser operation, remote users can dynamically open and close the firewall of the home gateway. The firewall rule creation is based on an authentication of the remote client, and thus only packets from the authorized client can pass through the firewall, we analyses the sorority design for home gateway in ubiquitous surroundings.

In spreading an internet service and developing a network technology, The interest of study about the remote control system using web environment increased. In treatise, We describe a design and an implementation of the gateway system that is based 3-tier model using corba in middleware. This system is applicatble various system environment because of using middleware and overcome a time limit and range limit because of using web browser interface.

우리는 현재 유선망에서 웹 브라우저와 여러 검색엔진을 통해 필요한 서비스를 찾고 다운로드 받을 수 있다. 그러나 이동 적응망에서는 사용자가 쉽게 사용할 수 있는 브라우저가 아직 개발된 것이 없으며 유선망에서와 같이 서비스 검색을 담당할 중앙의 서버를 가정할 수도 없다. 본 논문에서는 이동 적응망의 노드들이 망에 존재하는 서비스와 주변 노드들을 검색, 관리하기 위한 서비스 브라우저와 이를 뒷받침할 프로토콜을 소개한다.

일반적인 사이버 범죄 중에서 포탈사이트 게시판에 명예를 훼손할 목적으로 글을 올린 경우를 생각해보자. 인터넷 웹브라우저 내용을 출력하거나 화면캡쳐 도구를 이용하여 생성한 파일은 웹브라우저 내용을 클라이언트가 임의로 수정하여 출력하거나 화면캡쳐 파일을 수정할 가능성이 존재하고 무결성 보장이 힘들다. 본 논문에서는 실제 내컴퓨터의 모니터에서 보이는 화면은 얼마든지 조작이 가능함을 예를 들어 보일 것이며 화면캡쳐 파일의 무결성 보장을 위한 시스템을 제시하려고 한다.

멀티미디어 자료는 빠르게 증가하고 있는 반면, 텍스트 기반의 검색엔진을 이용한 멀티미디어 자료 검색은 자료 내부를 검색할 수 없는 단점으로 인하여 검색된 정보의 정확성과 정확한 정보의 위치를 찾는 것이 어렵다. 그래서 이러한 문제를 해결하고자 멀티미디어 Deep Tagging 개념을 이용하여 비디오 파일에 자동으로 Deep Tagging 을 생성하고 또한 기존 하이퍼텍스트 기반의 하이퍼링크를 하이퍼비디오로 확장한 브라우저를 제안한다.

As a voice browser is introduced, voice dialog application becomes available on the Web environment. The voice dialog application consists of voice Web pages that need to translate the dialog scripts into SALT(Speech Application Language Tags). The current Web pages have been designed for visual. They, however, are potentially capable of using voice dialog. This paper, therefore, proposes an automated voice Web generation method that finds the elements for voice dialog from Web pages based HTML and converts them into SALT. The automatic generation system of a voice Web page consists of a lexical analyzer and a syntactic analyzer that converts a Web page which is described in HTML to voice Web page which is described in HTML+SALT. The converted voice Web page is designed to be able to handle not only the current mouse and keyboard input but also voice dialog.

The existing information retrieval systems utilize thesaurus in order to search and retrieve the desired information even when the query is not accurate. However the cost for implementing and maintaining thesaurus is very high and it can not guarantee complete success of search/retrieval operation. Thus in this paper, Information Retrieval System using Keyword Network(KNetIRS) which was designed and implemented to solve these problem is introduced. Keyword Network composed of keywords which were extracted from documents. KNetIRS finds the appropriate documents by using the Keyword Network which is based on the concept of "inverted file". In addition, KNetIRS can carry out query expansion by using the Keyword Network Browser, and deal with the conjunction of "정보 검색", "정보", and "검색", by defining and implementing spilt function.

Java applets are downloaded from web server through internet and executed in Java Virtual Machine of clients' browser. Before execution of java applets, JVM checks bytecode program with bytecode verifier and performs runtime tests with interpreter. However, these tests will not protect against undesirable runtime behavior of java applets, such as denial of service attack, email forging attack, URL spoofing attack, and annoying sound attack. In order to protect malicious applets, a technique used in this paper is java bytecode modification. This technique is used to restrict applet behavior or insert code appropriate to profiling or other monitoring efforts. Java byte modification is divided into two general forms, class-level modification involving subclassing non-final classes and method-level modification used when control over objects from final classes or interface. This paper showed that malicious applets are controlled by java bytecode modification using proxy server. This implementation does not require any changes in the web sever, JVM or web browser.

Web pages with complex layout and small font size do not display well on large screen display such as TV because it has limited capabilities: long distance view, passive user attitude, limited input device like a legacy remote controller. We have designed and implemented new semantic zoom browsing facilities to support effective navigation on Internet-connected digital television with limited capabilities. Our browser performs partitioning of an HTML document content into semantic blocks. Semantic blocks present summarized information with more readable style and modified layout for optimal reading and browsing. Individual blocks can be selected by the user and zoomed in more detail information by the user. The scrolling on large display device needs more user interaction. Our browser modifies the layout of an HTML document with removing horizontal scrolling and minimizing vertical scrolling. This method allows users to easily view the web page by converting into optimal reading style and layout and to easily seek the information just with zooming.
