    Abstract: 雲端計算的發展為中小企業的資訊處理，帶來更多樣的選擇與更經濟的效 益。中小企業能夠使用公共雲端服務，如Google Docs，快速地將資訊傳遞 給客戶，能將心力集中在處理資訊上，而不必花費精力在建置網站的硬體、 軟體與維護等這些工具上。 然而雲端計畫的公共雲端服務為企業所帶來的生產力也可能為企業的檔案 管理帶來混亂與危機，而使得企業在擁抱新科技時顯得猶豫與裹足不前。 混亂來自兩方面：「資訊混亂」與「管理風險」。資訊混亂來自於內部檔案 與雲端檔案之間不一致的情況，造成認知錯亂與失序。管理風險來自於內 部的權限與雲端的權限之間缺乏一致性的對應關係，使企業擔憂自己的數 位資產在雲端上曝露在非預期的閱讀（外洩）與編輯（竄改）風險。 本計畫根據數位資產的資訊面向與權限面向，劃分成兩個子計畫，嘗試分 別探討該面向在區網與雲端之間一致性（同步）的問題，然後選擇具代表 性的公共雲端服務，整合實做成一個可行的方案，嘗試為數位資產在企業 內部的區域網路與外部公共雲端服務之間的一致性問題，提供公開程式碼 的解決方案。
    The development of cloud computing brings more flexible options of information technology for the small and medium business (SMB). With the help of public cloud services, such as Google Docs, the SMB share their business information with lower cost and higher efficiency. They do not need to take care of the facilities of how to share but what the information they want it to be coordinated. There is downside for this situation. The hybrid environment might mess up the digital assets of the SMB because of the leak of integrity between the interior repository and its counterpart in the cloud. The risky downside makes the SMB been hesitated on embracing the cloud technology even it could be beneficial in the long-term prospection. The downside has two aspects: “the chaos of information” and “the crisis of management”. The chaos originated from the possibility of informational-disagreement among the scattering copies. The crisis means the unauthorized access to the private-owned digital assets. Our research and development project plans to solve the problem by synchronizing the content and permissions between the local file repository and the cloud services. The project has been split into two affiliated sub-projects. The major project will base on the research results of sub-projects to build up an integrated solution by utilizes their libraries and components. And the solution is going to open source.
