A Smartphone has an ability accessing Internet by URL stored in NFC(Near Field Communication) Tag for storing the information of items, blogs and web pages. Because the system works through the Internet with URL, however, it needs to pay some costs like communication fee and time. If we can store the web page on the tags, we can save the communication overhead. But they have too small memory to store it. In this paper, we introduce the Micro-Webpage technology which can be stored in NFC tag or QR(Quick Response) code. To make a Micro-Webpage, we remove control tags from the web page to leave a user original content. The removed control tags are stored in our smartphone application as a template. The user content is also compressed to a smaller one by an lossless compression algorithm. When a tag is read, the stored content is decompressed and, it is combined with the template to make the original web page. We have implemented a prototype of Micro-Webpage system on Android platform and confirmed that the prototype has reasonable performance improvements in saving memory and loading web page time.

There are continuos tendencies toward that foreign tourists increase. Since 55% of them visit Korea without data communication for saving the communication costs, they can not utilize a variety of O2O services through QR/NFC/Beacon. There have been some researches to provide a smart map service based on the micro webpage technology even without data communication. But, they do not suggest how the templates are retrieved into their smart-phones. In this paper, we describe a mobile tourist information system for those who have no data communication. We utilize the micro webpage technology to develop a system for market promotion, shopping goods, and tourist maps. What matters in the micro webpage techniques is that the templates should be already downloaded to the users' smart phones before using it. The preceeded research did not mention the problem. We suggest a scheme that tourists obtain the tremplates in the information offices on the spot through Wi-Fi. We describe the details of the system, and evaluate the data overhead of templates and the time to be downloaded. We show that the overheads are endurable, which means that the system would be working well.

최근 인터넷 서비스 기술이 발달함에 따라 웹 서비스는 사용자의 컴퓨팅 환경에 많은 변화를 주었다. 시사, 경제, 게임/오락은 물론, 개인 금융까지도 웹 페이지를 통해 처리 된다. 이 때, 웹 페이지는 텍스트 형태의 코드를 전송받아 DOM 정보로 가공되어 웹 브라우저에 의해 사용자에게 보여 진다. 하지만, 이 정보들은 다양한 경로를 통해 접근이 가능하고 악의적인 목적으로 변조되어질 수 있다. 또한, 보안 매커니즘을 우회하여 사용자의 로그인 정보나 인증서를 획득할 수도 있다. 따라서, 본 논문에서는 이러한 웹페이지 변조 행위를 탐지하기 위해 웹 브라우저 중 대표적인 MicroSoft 사의 MS Internet Explorer의 Add-On 프로그램인 BHO를 이용하여 웹 컨텐츠에 대한 무결성을 검증하는 탐지 방법을 제안한다.
