The rapid development of digital media and communication network urgently brings about the need of data certification technology to protect IPR (Intellectual property right). This paper proposed a new watermarking method for embedding contents owner's audio signal in order to protect color image IPR. Since this method evolves the existing static model and embeds audio signal of big data, it has the advantage of restoring signal transformed due to attacks. Three basic stages of watermarking include: 1) Encode analogue ID owner's audio signal using PCM and create new 3D audio watermark; 2) Interleave 3D audio watermark by linear bit expansion and 3) Transform Y signal of color image into wavelet and embed interleaved audio watermark in the low frequency band on the transform domain. The results demonstrated that the audio signal embedding in color image proposed in this paper enhanced robustness against lossy JPEG compression, standard image compression and image cropping and rotation which remove a part of image.

This paper explores the determinants of the economic value of patents using a survival time analysis. The analysis is based on renewal information of about 250,000 patents filed from 1984 to 2005 in the Korea Intellectual Property Office. A patent right is valid only when its owner pays yearly maintenance fees. Failure to pay causes patent rights to be lapsed. We use the fact that more valued patents live longer and the lengths of their renewals can be closely related to their value. The value can be affected not only by its own technological aspects such as quality and breadth, but also by characteristics of its owners such as innovativeness and age. This paper presents patent-specific and firm-specific characteristics which influence patent value. The result of analysis implies that patent value depends on both the technological contents of the patent and general capabilities of a firm.

Recently the portion of international collaborative research in national R&D is being on the increase. But the management system of products from the international collaborative research is not sufficient. Not only the internal management system of public research institute, universities or government support R&D centers, are not enough, but also the legislations in government level are not established. In this paper, the problems and situations of product management system in international collaborative research are investigated and analyzed, and the methodology of improvement of them are presented.

DRM(Digital Right Management)은 디지털 컨텐츠의 불법유통과 복제를 방지하고, 적법한 사용자만이 컨텐츠를 사용케 하며, 과금서비스 등을 통하여 디지털 컨텐츠의 저작권을 관리하는 기술이다. 현재 많은 DRM 시스템이 개발되고 있고 관련 표준화 또한 활발히 진행 중이다. 본 논문에서는 DRM 표준인 MPEG-21 IPMP(Intellectual Property Management and Protection)를 고려하여 구현한 DRM기반 유통 시스템에 관한 설명과 IPMP 표준화 현황 및 이슈에 대해 기술한다.

1998년 9월 ITU-T TSAG의 제3차 회의에 이은 금년 4월의 제4차 회의에서도 IPR(Intellectual Property Right: 지적재산권) 논의를 통하여 ITU 지적재산권 정책에 대한 보완작업이 진행되고 있다. ITU 지적재산권 정책 보완의 초점은 특허권자가 표준화의 추진에 대하여 특허권 허여를 거절할 경우를 미연에 방지코자하는 절차 및 규정의 적용과 컴퓨터소프트웨어가 권고안에 포함될 경우의 저작권 보호 및 사용을 위한 방침의 정립에 있다. 이 두 가지 사안에 대하여 추진되고 있는 핵심 활동으로서 전자의 경우 ITU 특허정책에 대한 운용 가이드라인을 금번 4차 회의에서 보완하여 표준화된 특허성명서 양식과 함께 현재 시행하고 있으며, 후자의 경우는 독립적인 저작권 정책을 수립하고 있다. 본 고에서는 먼저 기본적인 ITU 지적재산권 정책상의 문제가 되는 배경을 설명하고, 정책 보완을 위한 3차 TSAG 회의로부터의 활동 경위와 금번 4차 회의 때의 주요 논의 내용 및 추진동향을 분석하여 소개하였다.

Digital watermarking has been recently proposed as the means of intellectual property right protection of multimedia data. We present a novel watermarking scheme to hide a copyright information in a digital image. The method Is based on the 2D DWT(Discrete Wavelet Transform) and image statistics. Gaussian and Laplacian noises as the watermarks are added to the large wavelet coefficients at the high and middle frequency bands in the wavelet domain. Experimental results show that the proposed Laplacian watermark is stronger to several common image distortions, such as noises, JPEG coding as different qualities, Gaussian blurring, and edge enhancement.

Digital watermarking is a technique which blends intellectual property right with security Blind watermarking 1S one of the difficult watermark technique because original data or inserted watermark is not needed. In this paper, we propose a new blind watermarking method using energy quantization in wavelet domain to insert watermark. The proposed method is robust for various attacks and attack strength because watermark strength is adaptively changed for energy variation of attacks. Simulation results show the proposed method is robust to various attacks such as noise addition, cropping, blurring, sharpening, maintaining imprescriptibility.

International trade conflict has been increased since WTO has appeared. Like this, the cause that the number of international trade conflict has been increased is by means of enlargement of agreements range. But some new facts have been added. They are Anti-dumping, subsidy, Countervailing duty, Safeguard, the norm of intellectual property right, the procedure of permitting importing products, Technical Barriers, agricultural products, and the area of textile. Since Japanese government has decided to give lavor import quarters to China without permission of Korea, Korean government formally presented the system of lavor import quarter to WTO DSB due to WTO agreement disobedience of Japan. Accordingly, this paper has the following purpose; to analyze situation on fiber dispute of Japan. Some methods about trade barrier against Japan need to be solved from another viewpoint owing to lavor IQ dispute.

This Paper is implementing IPMP system based on Server/client Structured Linux. We referenced OpenIPMP System, which is a reference software of IPMP (Intellectual Property Management and Protection) solution. Using this system, we developed multimedia contents service providing system using MPEG-21's REL(XML), which is applicable to new media service environment.

우리 저작권법은 저작권자에게 저작인격권을 통하여 성명표시권을 부여하고 있다. 저작권법 제12조에 의한 성명표시권은 저작권자가 자신의 저작물에 대하여 실명 또는 이명을 표시할 권리를 뜻한다. 우리 사회에는 대필작가, 소위 고스트라이터를 통해 저작물을 창작하고 최종 저작물(위탁저작물)에는 대필작가의 이름이 빠지는 경우가 관행적으로 이루어지고 있다. 그러나 법적 관점에서 볼 때 위탁저작물을 창작한 자는 대필작가이고, 대필작가의 이름이 저작물에 표시되지 않는 것은 성명표시권 침해에 해당한다. 또한 성명표시권과 같은 저작인격권은 일신전속성을 지닌 권리로 양도, 포기, 불행사가 불가능하다. 그렇기에 법적으로는 대필작가의 성명을 위탁저작물에 무조건 표시해야 하지만 현실은 그렇지 못하다. 그렇기에 본고에서는 이에 대하여 간략하게 살펴보겠다.
