異質性的應用系統程式整合研究

Abstract

現今社會上，各個公司行號或單位組織內部都充斥著許多的應用程式系統。使用者常會需要輸入許多組的帳號密碼來登入各個系統，不管是相關或不相關的；若遇上公司合併，更是加深使用者的困擾。

加上目前科技日新月異，使用者已經不再只是單純使用個人電腦來使用相關應用程式。人們可以利用許許多多的裝置，例如：個人桌上型電腦、手提電腦、PDA、手機或者是其他行動裝置來連結網路或使用相關應用系統。使用者面對這樣的情況，更是需要記住更多的系統連結方式或者是更多組的帳號密碼。

因應上述的情況，對於系統管理者而言在系統的維護及開發上，更是耗神費力。除了針對異質性的應用程式的維護管理外，更要費心管理異質性的資料內容以及資料庫的認證問題。這對維護者而言是非常費時的工作。

在這篇論文中，我們提出了幾個方法來解決這一類的問題：單一登入窗口及不同內容的早期繫結(Content early binding)可減低維護人員的負擔並提供使用者一個簡單的進入點；數位式權限管理則可有效管理使用者並保護富創意的資料內容。

Nowadays, every company or organization has many kinds of different application systems. Users usually need to remember several combinations of user account and password to logon different kinds of application systems, even the related functions. When different companies or organizations are merged, users will suffer more painful work. Also, as the technology evolves daily, users may use many different kinds of devices (for example: desktop personal computer, notebook, PDA, mobile phone, or other mobility devices) to access web site or other related application systems. Users usually need to remember more IP address links or many combinations of account and password information.

For system managers, they usually need to spent more efforts on the system maintenance in order to support these different needs. System manager not only needs to maintain the heterogeneous applications, but also the heterogeneous contents and databases authentication. It is a very time-consuming activity.

In this thesis study, these problems mentioned above are addressed. Specifically, we investigate single-sign-on approach and content’s early binding approach to reduce the maintenance efforts and provide an easy way for users to logon these systems. Also a DRM mechanism is provided to achieve access control and created digital contents protection.
