This study analyzes the copyright problems of document delivery services based on interlibrary loan which are operated by KERIS and KISTI according to the agreements with KORRA. As a result of the study, we found that there are limitations of the libraries and copyright works to implement the document delivery services. Also, the electronic document delivery is the only between librarians and there is no provisions in the agreements for individual users who are not affiliated to libraries. This study suggests introduction of the ground provision for the interlibrary loan in the Copyright Act of Korea and development of authoritative guideline for details of document delivery services. Also, the study suggests that end users to request documents could be print out it but the library have to install systems to avoid copyright infringement. Finally, the study proposes the copyright fee based model for the document delivery services for individual users.

Based upon the provision of limitation of copyrights, libraries may provide the document delivery service which supplies copies of journal articles and book chapters owned at other libraries by request of users. However, more proactive information service is required as more users want to use the digital delivery of documents published overseas. This study reviews copyright law of Korea and international conventions related to the document delivery service. It then examines foreign cases to see how overseas information centers clear copyrights. Finally this study suggests that copyright clearance methods be adopted to make a proactive information service. Through those methods, a new information service model may be planned, which meets various information needs while protecting copyright.

Most of the existing methods make the index key with every 6 words in every sentence in a document in order to identify copyright infringement between two documents. However, these methods has the disadvantage to take a long time to inspect the copyright infringement because of the long indexing time for the large-scale document. In this paper, we propose a method to select the longest word (called a feature bock) as an index key in the predetermined-sized window which scans a document character by character. This method can be characterized by removing duplicate blocks in the process of scanning a document, dramatically reducing the number of the index keys. The system with this method can find the copyright infringement positions of two documents very accurately and quickly since relatively small number of blocks are compared.

Data structure in Framework interior is doing and propose copyright expression language of XML base of REL to establish copyright connection data standard and normalized based on no XML. But, a tool that can be easy as must understand whole framework and can have problem in to edit REL and create copyright document fast was required. In this paper, research about method that edit REL document and develop and spend a edit tool that tan be that expressing intuitionally.

The watermarking is a method to achieve the copyright protection of multimedia contents. Among several media, the left documents show very peculiar properties: block/line/word patterning, clear separation between foreground and background areas. So algorithms specific to the text documents are required that meet those properties. This paper proposes a novel watermarking algorithm for the grayscale text document images. The algorithm inserts the watermark signals through the edge direction histograms. A concept of sub-image consistency is developed that the sub-images have similar shapes in terms of edge direction histograms. Using Korean, Chinese, and English document images, the concept is evaluated and proven to be valid over a wide range of document images. To insert watermark signals, the edge direction histogram is modified slightly. The experiments were performed on various document images and the algorithm was evaluated in terms of imperceptibility and robustness.
