올해 정보문화의 달은‘함께하는 디지털 세상’이라는 주제에서 나타나듯이 정보화 격차 해소와 올바른 인터넷 이용에 초점을 맞췄다. 한국정보문화진흥원은 6월 한 달을 인터넷 이용률의 증대에도 불구하고 여전히 정보화에서 소외된 계층과 날로 확산되는 인터넷 유해 정보에 대처하기 위한 대국민 홍보의 장으로 적극 활용했다. 이와 함께 정부 산하기관, 체신청, IT 관련기업, 정보나눔실천운동본부, 정보보호실천협의회 등 관련 단체와 시민단체도 총 출동해 범국민적 건전 정보문화 확산에 앞장섰다. 17회 정보문화의 달을 맞아 6월 한달 동안 펼쳐진 주요 행사를 소개한다.

The digital watermark is one of important techniques to solve copyright authentication problems of digital media. Researches on the digital watermark are rapidly increasing in various media. The watermark system can resist some attacks such as signal attack, geometric attack and protocol attach. However, so far the robustness of the watermark needs to be improved. This paper suggests a watermarking technique with which a watermark is embedded on a coefficient of wavelet-based frequency band and extracted from it for protection of property rights and authentication of Blackfin processor-based digital sound. By carrying out hardware implementation of the suggested sound watermarking, the commercialization of protection of property rights and robustness of watermarks resulted from development of high-level programs can be confirmed.

I would like to analyze the customers accommodation availability of the provisional 'smart board,' having specific mode and style, as a circulation platform of digital contents with using a statistic model in order to find a way and means to activate legal circulation of convergence individual products. The smart board means a circulation platform for both users' convenience and copyright protection, by being conveniently able to upload personal convergence digital contents or apply various licence to the uploaded contents according to the purpose of use. Under these premises of the smart board, this paper is going to focus on verifying to find out which factors, such as users' profile attributes, contents using behaviors, awareness of licence and etc, influence on the intention of using the smart board of general users by using a logistic regression model.

본 논문에서는 국내에서 DTV 전환에 대비한 기술적 보호조치 방안 마련을 위하여 기술적 보호조치의 방법들에 대하여 간략히 살펴보고 이를 바탕으로 유통활성화를 도모하기 위한 기술적 보호조치 방법을 제안하였다. 디지털 방송프로그램을 보호하기 위한 기술적 보호조치는 인터넷을 통한 불법유통을 방지하여 저작권자의 이익을 도모하려는 목적이나, 이로 인하여 방송프로그램 유통의 지나친 억제는 저작권자의 권익보호를 위하여 바람직하지 않다. 따라서 사용자가 보다 편리하고 저렴한 비용으로 방송프로그램을 재시청 및 재활용할 수 있도록 방송프로그램의 기술적 보호조치를 마련하는 것이 저작권자의 권익을 극대화 할 수 있다. 이러한 방법의 하나로 방송프로그램에 콘텐츠 보호선호 및 콘텐츠의 이용을 위한 연결정보를 포함하여 송출하고 방송수선단말에서 사적이용범위 내에서는 방송프로그램을 자유롭게 녹화 및 복사하여 시청할 수 있지만, 사적이용범위 밖으로 복사/전송 시에는 콘텐츠 연결정보만을 복사하고, 이를 재생할 때는 콘텐츠 연결정보를 이용하여 방송프로그램 유통서버로 연결하며, 유통서버와의 통신을 통하여 저렴하고 편리하게 방송프로그램을 사용할 수 있는 기술적 보호조치의 한 방법을 제안하였다.

This study investigates the IPI (Information Protection Intention) of DHS (Digital Healthcare Service) providers by introducing PMT (Protection Motivation Theory). This study examines the effects of protection motivation, such as threat appraisal and coping appraisal, on IPI, such as ICI(Induction Control Intention) and SDI(Self Defense Intention). The research model, based on the PMT, adopted severity, vulnerability, reaction efficacy and self-efficacy as independent variables. The research model was validated through quantitative research, a survey of 222 DHS providers in South Korea, using structural equation modeling. The results show that (1) a clear awareness of the consequences of security threats increases the understanding of DHS providers on the severity of closure of healthcare information, and thus may decreases abuse of DHS by providers; (2) user confidence and satisfaction on the security system may make them be confident that they can handle the closure of healthcare information by themselves; and (3) although DHS providers are realizing the consequences of closure of healthcare information, they think that they are unlikely to encounter such situations. As a result of this study, venture companies that provide DHS need to provide contents that can continuously increase providers' security level in order to increase providers' information protection intention. It suggests that IPI is important through trust of healthcare service providers.

Today, Digital Right Management (DRM) is used to protect copyrights of digital contents from illegal reproduction and redistribution. Unfortunately, current DRM systems are causing user's discomfort because of lack of mutual compatibility. In order to overcome this drawback, technologies for interoperability of heterogeneous DRM systems are developing. In this paper, we study the protection profile for conversion technologies of heterogeneous DRM systems, using the Common Criteria. Especially, this paper is written by reuse of the existing protection profile. Therefore, performance analysis reveals that efficiency of time and cost is significantly improved. This protection profile can be used by contents provider and administrator who manage user's copyrights to reference data for copyright protection.

The illegal copying and redistribution of digitally-stored information is a crucial problem to distributors who electronically sell digital data. fingerprinting scheme is a technique which supports copyright protection to track redistributors of electronic information using cryptographic techniques. Anonymous asymmetric fingerprinting scheme prevents the merchant from framing a buyer by making the fingerprinted version known to the buyer only. And this scheme allows the buyer to purchase goods without revealing her identity to the seller. In this paper, a new anonymous asymmetric fingerprinting scheme with TTP is introduced. The buyer's fingerprint is generated by the Fingerprint Certificate Authority which is a TTP. When the seller embeds the fingerprint in the digital data, the protocol uses the homomorphic encryption scheme. Thus the seller cannot know the buyer's fingerprint and the buyer's anonymity is guaranteed by using anonymous key pair.

Recently, with the advance of network and internet technologies, it is appeared the Problem that the digital contents such as image, voice and video are illegally pirated and distributed. To protect the copyright of the digital contents, the digital watermarking technology of inserting the provider's information into the contents has been widely used. In this paper, we propose the method of applying the digital watermarking into biometric information such as fingerprint and iris in order to prevent the problem caused by steal and misuse. For that, we propose the method of inserting watermark in frequency domain, compare the recognition performance before and aster watermark inserting. Also, we experiment the robustness of proposed method against blurring attack, which is conventionally taken on biometrics data. Experimental results show that our proposed method can be used for protecting iris and fingerprint data, efficiently.

The concept and discussion of copyright should reflect changes in using environments of digital properties and developments of technology. Further discussions are required about protection, transfer and usage of copyright for user created contents or digital activities. Digital archives should clarify the ranges of permitted usage or guides to quotation. One should not be biased toward regulating digital copying, but consider the value of diverse transformation of digital properties. This will trigger tension between private and public usage, or sharing of digital fabrications, which leads to the necessity of discussions on policy level. The interpretation of copyright is limited to protecting the copyright owner's right, but it should be suggested to widen the range to permitting fair use. The extended fair use of digital contents and by clarifying specific rules will activate creation and distribution of digital contents and contribute to more productive usage of innovation.

최근에는 디지털 미디어 기술의 발달로 다양한 형태의 미디어 서비스가 개발되고 있으며 미디어 콘텐츠의 불법 복제를 방지하고 콘텐츠 제작자의 권리를 보호하기 위해 많은 DRM 기술이 개발되고 있다. 여러 개의 DRM을 사용하려면 DRM 서비스 제공 업체와 콘텐츠 제공 업체가 별도의 계약을 통해 상호 의존적인 방식으로 서비스를 제공해야한다는 제약이 있다. 본 논문에서는 클라우드 기반의 DRM 스토어를 제안한다. 이 시스템은 DRM 서비스 제공 업체가 여러 DRM을 쉽게 등록하고 콘텐츠 제공 업체는 자신의 서비스 특성에 따라 DRM을 필요한 만큼 사용할 수 있는 오픈 마켓 형식의 DRM 중계 서비스이다.
