Digital watermarking is the technique that embeds invisible signalsincluding owner identification information, specific code, or pattern into multimedia data such as image, video and audio. Watermarking techniques can be classified into two groups; robust watermarking and fragile(semi-fragile) watermarking. The main purpose of the robust watermarking is the protection of copyright, whereas fragile(semi-fragile) watermarking prevents image or video data from illegal modifications. To achieve this goal watermark should survive from unintentional modifications such as random noise or compression, but it should be fragile for malicious manipulations. In this paper, an invertible semi-fragile watermarkingalgorithm for authentication and detection of manipulated location in MPEG-2 bit-stream is proposed. The proposed algorithm embeds two kinds of watermarks, which are embedded into quantized DCT coefficients. So it can be applied directly to the compressed bit-stream. The first watermark is used for authentication of video data. The second one is used for detection of malicious manipulations. It can distinguish transcodingin bit-stream domain from malicious manipulation and detect the block-wise locations of manipulations in video data. Also, since the proposed algorithm has an invertible property, recovering original video data is possible if the watermarked video is authentic.

In this paper, we proposed fast and efficient algorithm for detecting near-duplication based on content based retrieval in large scale video database. For handling large amounts of video easily, we split the video into small segment using scene change detection. In case of video services and copyright related business models, it is need to technology that detect near-duplicates, that longer matched video than to search video containing short part or a frame of original. To detect near-duplicate video, we proposed motion distribution and frame descriptor in a video segment. The motion distribution descriptor is constructed by obtaining motion vector from macro blocks during the video decoding process. When matching between descriptors, we use the motion distribution descriptor as filtering to improving matching speed. However, motion distribution has low discriminability. To improve discrimination, we decide to identification using frame descriptor extracted from selected representative frames within a scene segmentation. The proposed algorithm shows high success rate and low false alarm rate. In addition, the matching speed of this descriptor is very fast, we confirm this algorithm can be useful to practical application.

Open educational resources(OER) enable the spread of mutual information exchange and provide advantages to both their users and institutions, such as reducing costs, improving content quality, and establishing relationships. The recent research on OER was about their connection to formal education, copyright trends, and corporate e-learning. There have been very few studies, however, on the utilization of OER and on the problems related to their practical use. Thus, this study was conducted for the purposes of analyzing the status of OER usage in education-related institutions and of providing suggestions for institution operation based on the analysis results, to promote the use of OER. A survey was conducted among more than 200 institutions in Asia, and the survey results showed that 'images and visual materials' are the most commonly used materials in Asia, and that the factors barring OER usage in the said region are 'lack of awareness', 'lack of skills', 'the absence of a reward system', and poor cooperation in participation. To promote OER usage, each institution should provide training courses about awareness, utilization skills, and copyrights. There is also a need to provide support for the establishment of reward systems and environments for OER usage. Finally, more active participation is required for inter-agency cooperation in OER sharing.

본 연구는 지적재산분쟁의 중재에 대한 미국 케이스에 관한 연구입니다. 본 연구의 목적은 한국의 지적재산분쟁의 중재에 대한 추후 연구와 가까운 장래에 비교연구를 위해서 지적재산에 관련된 케이스들에 관하여 미국의 연구들을 논하는데 있습니다. 본 연구에서 지적재산 관련 사건들의 중재에 관한 미국케이스들을 채택하였습니다. 그리고 본 연구의 목적 달성과 효과적인 연구를 성취하기 위해 그 케이스들을 인용하였습니다. 그러므로, 본 연구의 구성은 특히, 라이센싱분쟁의 중재, 특허분쟁의 중재, 저작권분쟁의 중재를 위하여 지적재산분야와 중재 분야에 있는 케이스로 이루어져 있습니다. 중재조항은 분쟁에 관해 누가 결정할 것인가 그리고 분쟁이 중재 가능한가 아닌가에 관하여 법원에서 중재적격 문제들을 분석할때에 계약 원칙을 적용하게 됩니다. 일반적으로, 중재적격의 의문은 사법적 분야의 질문에 관한 것 입니다. 그러나, 중재조항이 분명하고, 명백하고, 오해없는 문구들인 곳에서 법원은 연방 중재법이 중재조항과 중재범위를 포함하고 있기 때문에 중재를 존중합니다. 그러므로, 저런 경우에 중재인은 중재적격을 판단 할 수 있습니다. 그러나, 미국에서 법원은 어떤 케이스들은 ICC 룰로 구속되어지고 그리고 다른 케이스들은 AAA 룰로 구속 되어지는 것을 발견했습니다. 어떤 룰이던지 간에 중재조항은 주의깊게 만들어야만 하고 그리고 분명하고 명백한 구문을 제공하여야만 한다는 것을 법원에 의해 요구되어지고 있습니다. 본 연구에서 발견한 점들은, 라이센싱분쟁의 중재에 있어서, 중재합의의 범위가 광범위 또는 제한적일지라도 양 당사자의 중재조항을 위해 계약에서 분명하고 명확한 문구를 만드는 것이 중요합니다. 이것은 우리에게 계약의 원칙이 분쟁에서 적용 되어지고 있다는 것을 보여 주고 있습니다. 그래서, 중재조항의 조문은 법원이나 중재인에게 논쟁 또는 오역이 없게 확실하고 분명하게 명시하여야 합니다. 특허분쟁의 중재에 있어서, 대부분 법원들은 케이스들을 분석할때에 광범위한 중재조항에 따라오고 있습니다. 중재적격 결정의 테스트로서 계약에서 "arising under" or "relating to" 구절은 ADR을 위해 그리고 분쟁의 예방을 위해 중재가 광범위한 문구를 포함하고 있는가 아닌가를 보는데 중요합니다. 더구나, 특허 또는 특허관련 권리들 하에서, 중재는 연방중재법에 의해 지배되기 때문에 계약은 특허 유효성 또는 침해 문제들이 중재를 통한 분쟁을 해결하도록 하나의 문구를 포함해도 됩니다. 그러므로, 이 분석은 미국의 케이스들을 비교한 결과로서, 한국중재법도 또한 모든 필요한 조문들이 그것들이 광범위하건 제한된 범위이건 간에 모호한 이슈들을 피하기 위해 분명하고 오해없는 문구들이여야 한다는 것을 제시합니다. 지적재산분쟁의 중재에 있어서, 케이스에 근거하여 발견한 점들은 저작권법을 포함한 광범위한 중재조항이 있는 경우 저작권의 유효성은 법원이 독점할 수 없다고 법원은 판단했습니다. 그리고 연방중재법은 법원이 청구취지가 중재가능한 클레임들에(arbitrable claims) 관하여 중재를 강요하도록 지원하고 있습니다. 이것은 저작권 케이스일지라도 계약에 있어서 중재조항이 법원이 중재를 강요하도록 중재가능한가 아닌가 결정하는데 분쟁에 있어 중요한 역학을 한다는 것을 제시합니다. 그러므로, 본 연구는 계약에서 광범위한 중재조항은 중재인이 지적재산 클레임에 대해 판정 또는 룰을 결정하게 허용한다는 것을 발견했습니다. 본 연구의 결과들은 계약에 있어 중재의 범위는 계약의 원칙을 적용한다는 것입니다. 그리고 중재조항에 있어서 침해와 유효성 문제들의 결정은 계약 해석에 관련되어 있다는 것을 제시합니다. 그러므로, 양 당사자가 분명하고 명확하게 달리 결정하지 않았다면, 양 당사자가 중재에 대해 동의했는가 아닌가의 의문점은 법원에 의해 결정되어지는 것입니다. 이것은 분명하고 명확한 문구가 중재조항에 존재하지 않는다면 중재인에 의해 결정되지 않는다는 것을 뜻합니다. 중재조항은 명백하게 중재인에게 결정의 권한을 주어야만 한다는 것입니다.

In the intellectual based society of the 21th century, intellectual property of nation and enterprise management has been the key element of nation's competitiveness and development. Therefore in countries like Korea, China, and many other countries, intellectual property of advancement strategy are being constructed and intellectual properties are protected at national level. Top priority task of protecting the intellectual property is to efficiently resolute intellectual property right disputes. Considering the nature of intellectual property right and arbitrage system, arbitration to solve intellectual property disputes is realistically the best method. However, not all cases of them are qualified. In order to relieve the intellectual property disputes through arbitration, qualification must be obtained. During the process, generally and globally, intellectual property right dispute is evaluated by three parts, intellectual property right contract dispute, intellectual property right violation dispute, and intellectual property right validity dispute. Based on UN's "Convention on the Recognition and Enforcement of Foreign Arbitral Awards Agreement" in 1958, June 10th, in New York, both arbitrage organization and judgment can be approved in both Korea and China countries. However, as of today, there is a big gap of arbitration qualification between two countries, which can be troublesome if intellectual property right disputes arise. For instance, in Korea, intellectual property right contract disputes and intellectual property right violation disputes are both generally accepted as arbitration qualification. However for intellectual property right validity dispute, arbitration qualification is only accepted for non-registered intellectual property as in copyright entity. It does not apply to other registered intellectual property right as in patents. In China, arbitration qualification is accepted for intellectual property right contract dispute, and also accepted for intellectual property right violation dispute to copyrights but restricted to others. As for intellectual property right validity dispute, arbitration qualification is completely denied. Therefore, when there is an intellectual property right dispute between Korea and China, the biggest problem is whether China will accept arbitrage judgments made in Korea. Theoretically, arbitrage judgement made in Korea should be also accepted in China's court. However, considering the criticism of China's passive nature of arbitration qualification for its own local intellectual property right disputes, it's very unlikely they'll actively accept arbitrary judgment made in foreign countries. Korea and China must have a more open minded approach for intellectual property disputes and arbitration qualification. Base on WTO's Intellectual Property Right Agreement, it's being defined as private right. Therefore, sovereign principle should be the basic principle of solving intellectual property right disputes. Currently, arbitration qualification is expanding internationally. So both Korea and China must also follow the trend expand the arbitration qualification with a more open minded and forward looking approach, for the good of intellectual property disputes.

The world is focusing on e-books as the e-book market is growing rapidly as a fused industry at the crossroads of information technology and digital content. Many countries are actively participating in this new market and leveraging on its potential and growth, while Korea's market is still in its preliminary stage. There is a good reason to be concerned over the fact that access to digitalized materials that are the most relevant to the current time are not readily available. Therefore, the strategy in collecting and utilizing content must be newly refurbished. In order to do this, the legal issues and policies related to digital libraries must be considered. The most relevant examples from abroad are Google Book Search and the EU's Europeana project. Then, what are the necessary measures for Korea to materialize its own digital library? Digital libraries can significantly influence social welfare and bring forth economic effects. Social preparation surrounding this subject should continue to increase because digital libraries will change the manner in which people share and use information. Therefore, this paper aims to examine the legal and economic problems and issues related to the establishment of digital libraries as well as to provide policy recommendations.

Purpose - The purpose of this study is to subdivide trade transaction-centered structure in a logistics/distribution industry system to apply blockchain, to establish and resolve with which types of technology, and to provide policy direction of government institution and technology to apply blockchain in this kind of industry. Research design, data, and methodology - This study was conducted with previous researches centered on cases applied in various industry sectors on the basis of blockchain technology. Results - General fields of blockchain application include digital contents distribution, IoT platform, e-Commerce, real-estate transaction, decentralized app. development(storage), certification service, smart contract, P2P network infrastructure, publication/storage of public documents, smart voting, money exchange, payment/settlement, banking security platform, actual asset storage, stock transaction and crowd funding. Blockchain is being applied in various fields home and abroad and its application cases can be explained in the banking industry, public sector, e-Commerce, medical industry, distribution and supply chain management, copyright protection. As examined in the blockchain application cases, it is expected to establish blockchain that can secure safety through distributed ledger in trade transaction because blockchain is established and applied in various sectors of industries home and abroad. Parties concerned of trade transaction can secure visibility even in interrupted specific section when they provide it as a base for distributed ledger application in trade and establish trade transaction model by applying blockchain. In case of interrupted specific section by using distributed ledger, blockchain model of trade transaction needs to be formed to make it possible for parties concerned involved in trade transaction to secure visibility and real-time tracking. Additionally, management should be possible from the time of contract until payment, freight transfer to buyers through land, air and maritime transportation. Conclusions - In order to boost blockchain-based logistics/distribution industry, the government, institutionally, needs to back up adding legal plan of shipping, logistics and distribution, reviewing standardization of electronic switching system and coming up with blockchain-based industrial road maps. In addition, the government, technologically, has to support R&D for integration with other high technology, standardization of distribution industry's blockchain technology and manpower training to expand technology development.

Software license agreements, to be useful in the mass market, could not be individually negotiated, and had to be standardized and concise. The software license agreement needs to be presented to the licensee-users in a fashion that would allow for mass distribution of software, also for it to enforceable, that would draw the users' attention to the terms and conditions under which the publisher allowed the use of the software. These needs have been accomplished, with or without fail, through so called the "shrink-wrap licenses" Shrink-wrap licenses purpose to transfer computer softwares to their users by defining the terms and conditions of use of the software without implicating the "first sale doctrine" of the Copyright Act. These shrink-wrap licenses have become essential to the software industry. However, in USA, the law applicable to these licenses has been unclear and unsettled. Courts have struggled to develop a coherent framework governing their enforceability. Meanwhile, the National Conference of Commissioners on Uniform State Laws ("NCCUSL") in USA promulgated the Uniform Computer Information Transaction Act ("UCITA") governing contracts for computer information transaction on July 29, 1999. One clear objective of UCITA was to settle the law governing the enforceability of shrink-wrap licenses. In these respects, this paper first introduces the various forms that shrink-wrap licenses take(at Part II. Section 1.), and explains the main advantages of them(at Part II. Section 2.) Here it shows how shrink-wrap licenses value themselves for both software publishers and users, including that shrink-wrap licenses are a valuable contracting tool because they provide vital information and rights to software users and because they permit the contracting flexibility that is essential for today's software products. Next, this paper describes the current legal framework applicable to shrink-wrap licenses in USA(at Part III). Here it shows that in USA the development of case law governing shrink-wrap licenses occurred in two distinct stages. At first stage, judicial hostility toward shrink-wrap licenses marked such that they were not enforced pursuant to Article 2 of the Uniform Commercial Code. At second stage, courts began to recognize the pervasiveness of shrink-wrap licenses, their indispensability to the rapidly expanding information technology industry, and the urgent need to enforce such licenses in order to maintain low prices for consumers of computer hardware or software, resulting in the recognition of shrink-wrap licenses. Finally, in view of the importance of UCITA, this paper examines how it will affect the enforceability of shrink-wrap licenses(at Part IV). The drafters of UCITA, as well as the scholars and practitioners who have criticized it, agree that it validates shrink-wrap licenses, provided certain procedural protections are afforded to purchasers. These procedural protections include the licensee end-user must (i) manifest his assent to the shrink-wrap license, (ii) have an opportunity to review the shrink-wrap license, (iii) have a right to return the product without costs.

According to the changes of the mobile environments, the usage and interest of the Android apps have been increased. But the usage of illegally-copied apps has been also increased. And the transparency and dependability of the app markets has been decreased. Therefore there are many cases for the copyright infringement of app developers. Although several methods for preventing illegally-copied apps have been studied, there may exist possible ways to bypass the methods. Since it is difficult to find out the first distributors of the illegally-copied apps, it is not easy to punish them legally. This paper proposes the method of detecting illegally-copied apps. The proposed detector can detect the illegally-copied apps using odex file, which is created when the app is installed. The detector can also find out the information of the first distributors based on forensic watermark technique. Since the illegally-copied app detector is running as a service on the system server, it is granted that the detector hides from the users. As an experiment result, the illegally-copied app detector takes on average within 0.2 seconds to detect and delete an illegally-copied app.

Early stages of technology valuation have been often overlooked or under-represented. The early stage technologies are even riskier due to their inadequacy of commercial development and market applicability. More than 95% of patents fail to earn any revenues so that the majority of patents were valueless. Technology transfers from laboratories at universities and research institutes to industrial firms have increased to acquire value from invented technologies. Technology transfer, a process of transferring discoveries and innovations resulted from research to commercial sectors, typically comprises several steps: disclosing the discoveries and innovations, i.e., intellectual property (IP), evaluating the IP's economic prospects, securing a patent, copyright or trademark for the IP, commercializing the technology through licensing, forming a joint venture, or selling. At each of those stages in the research and development of technology, the value of technology would play a very important role of making decision on the movement toward the next step, however, the financial value of technology is not easy to determine due to a great amount of uncertainty in the course of research and development, and commercialization. This paper refers to technology embodied as devices, equipment, software or processes primarily developed at public research institutions such as universities. Sometimes it is also as the result of externally financed projects contracted with industry. Nearly always technology developed at public research entities results in laboratory prototypes. When it is required to define the technology transfer contract terms for the license of the university patrimonial rights to external funding companies or other interested parties, a question arises: what is the monetary value? In this paper, we present a method for technology valuation based on the identification of specific value points related to its development. The final technology value must be within previously defined value limits. This paper consists of the review of issues related to technology transfer and commercialization, the identification of characteristics of technologies in the early stage of technology development, the formulation of framework of methods to value the early stage technologies, and the conclusion and implication of the previous review.
