摘要: | 在這篇論文中,我們把傳統的買賣方浮水印協定帶到了雲端的環境中,並且利用了改進版展頻浮水印的技術,讓浮水印能夠更加的穩固。根據不同的雲端服務模型,我們提出了兩種不同的協定:在第一個協定中,雲端扮演的是基礎設備的提供者,賣方可藉此來大幅節省運算和溝通成本;而在第二個協定中,雲端扮演著平台的提供者,她提供一個買賣平台讓買方和賣方能在上面自由地做交易。利用雲端提供的軟硬體資源和隨用付費的商業模型,我們可以建立一個公平、有效率而且安全的多媒體交易環境。就我們所知,我們是第一篇把買賣方浮水印帶到雲端上的論文,不僅如此,我們還提供了對於消費者權利、規模化、穩固性問題的一個解決方案。 In this thesis, we expand the well-known Buyer-Seller protocol to Cloud environment, in which improved spread spectrum watermarking scheme is included to enhance the overall performance. Depending on the service mode the Cloud provided, two Cloud-based Buyer-Seller protocols are proposed. In the first protocol, Cloud behaves as a service infrastructure provider. Seller uses Cloud to speed up his computation and save storage and bandwidth costs. In the second protocol, Cloud behaves as a service platform provider. She offers an E-commerce platform to activate the transaction between Buyer and Seller. Owing to Cloud’s computation power and its Pay-as-you-go business model, we can build an efficient, effective, fair and secure service for multimedia trading. To the best of our knowledge, the proposed scheme is the first one that brings Buyer-Seller protocol to Cloud environment, and provides a solution to customer’s rights, scalability, and robustness issues in multimedia content distribution. |
