以多伺服器實踐高可用可回，復資訊隱藏之研究

Study of Implement High Availability Reversible Information Hiding with Multi-Server

資訊隱藏技術可應用於傳送國家及國防機密訊息，但若只有一台伺服器提供資訊隱藏技術服務，當執行資訊隱藏服務之主機因不明原因中斷服務，則會造成終端使用者無法利用執行資訊隱藏服務之主機將文件進行處理，造成服務中斷。目前資訊系統應用的發展趨勢乃能提供高可用服務為目標，避免因單一資訊系統主機中斷服務而導致無法進行後續作業，故本研究提出「以多伺服器實踐高可用可回復資訊隱藏之研究」，有效提供政府單位可靠的資訊隱藏服務。

"The data-hiding technology can be used to transmit confidential information about state affairs and national defense; however, if there is only one server providing the data-hiding technology service, and the server breaks down for unknown reasons, service will be interrupted, and terminal users will not be able to process files using that server. The development of the current information-system application is aimed at providing high-availability services. In order to avoid situations where a single information-system server stops functioning, which would cause half of the subsequent operations to fail, this paper proposed a ''Mesos architecture-based, high-availability, reversible data-hiding technology'' to provide government with effective and reliable data hiding services."
