Purpose: Due to the rapid growth of e-commerce in Thailand, the operational excellence of distribution service providers has been elevated. Thus, this research investigated the key drivers of operational performance of e-commerce distributors in Thailand. The research contains key variables: the analytics capabilities of an organization, supply chain disruption orientation, innovation capability, and operational performance. Research design, data, and methodology: An online survey is administered to top managers and key personnel (N=425) employed for at least one year in Thailand's top five e-commerce distributors. The sampling methods were conducted using purposive sampling, quota sampling, and convenience sampling. Confirmatory Factor Analysis and Structural Equation Model were applied to analyze and confirm the model's goodness-of-fit and hypothesis testing. Results: The findings reveal that an organization's analytics capabilities significantly affect supply chain disruption orientation and supply chain resilience. Furthermore, operational performance is affected by supply chain disruption, supplier quality management, and innovation capability. Nevertheless, supply chain resilience and digital supply chain have no significant effect on operational performance. Conclusions: The results imply that supply chain digitalization could drive higher operational performance. Distribution businesses are encountering transformation and disruption, which should address the high level of a digital supply chain, innovation, and quality management to maximize their profit margin and delivery service quality.

In this paper, we propose a key management scheme which can provide delivery of the key used to encrypt a digital content from the package server to digital rights management (DRM) clients in a secure manner. The proposed scheme can protect digital content from attacks since an encrypted digital content is sent by a package server and only DRM clients can decrypt the encrypted digital content. It protects the key not only from purchasers but also among the other principals who manage the distribution and license servers.

Video Content owners seek to squeeze the maximum amount of revenue from their assets via distribution into more territories. Digital Cinema Package(DCP), trusted solution to distribute protected content to theaters, caters to relatively small user base, which limits revenue. With the growth of the Internet & other digital media, the economics of media content has changed dramatically. Security remains main concern to deliver content to millions of consumers using intelligent digital display devices like Tablets, Smartphones, Smart TVs, Desktop & Laptop. By making the video content available to this segment securely, content owners will benefit from increased revenue. Through this paper we propose Open Source HomeDCP model to distribute the content to home users for offline viewing. We propose to include other open source CODEC than JPEG2000/MPEG2, which are specifically designed for theatrical performance. Final image size will be further reduced considering the display device resolution where video will be finally played. Key Delivery Message(KDM) system to be altered to suit new devices. This will be a big boost to Content Economy as content owners would be able to distribute the content securely to the wider audience & ensure more revenue.

유비쿼터스 환경은 디지털 홈 기기들이 시간과 공간에 제약을 받지 않는 멀티미디어 서비스를 제공한다. 하지만, 디지털 콘텐츠의 사적복제 보장을 통한 콘텐츠의 이용 편리성 보장(Fair Use)이 이루어지지 않고 콘텐츠의 무차별적인 배포와 불법 콘텐츠의 사용 등으로 인해 피해를 주고 있는 것이 현실이다. 이러한 문제점을 해결하기 위해 등장한 DRM 시스템은 단말기에 저장된 라이선스의 보호와 콘텐츠의 재배포에 따른 라이선스 관리를 수행하지 못하는 문제점이 있다. 본 논문에서는 유비쿼터스 환경에서 DRM 시스템의 문제점을 해결하기 위한 대안으로서 콘텐츠와 라이선스에 대한 오용행위 감사 및 불법 대규모 유통을 사전에 차단하고 법적 대응을 위해 디지털 증거 생성 및 관리가 가능한 디지털 포렌식 모델을 제안한다.
