設計及製作一文件保護與講解錄製之應用系統-以PDF和TXT文件為例

Abstract

隨著資訊發達、網際網路的便捷，文件原始作者(content creator)可以輕易地將自己製作的文件，透過網路在平台上分享知識；讀者(content reader)亦可透過網路，輕易取得該文件來閱讀、複製、列印、甚至是編輯，這對文件原始作者的智慧財產權是一重大打擊。因此，我們須思考如何對文件原始作者分享的文件作保護，以維護文件原始作者該有的權益。

許多關切這個議題的公司：如微軟，從 Microsoft Office 2003 版本開始提供文件保護的機制，稱作IRM(Information Right Management)的文件加密管理[4][5]。每位使用者或群組根據文件原始作者定義的存取層級，賦予使用權限：讀取、變更或完全控制；Adobe在2006年12月發佈Adobe LiveCycle Policy Server 7.2[8]，對於Adobe Acrobat文件播放器權限控管的生命週期從文件建立直到歸檔與銷毀，之中透過發送與協同合作方式來持續保護並控管文件。

不論是微軟或者Adobe，都僅針對自己發展的文件作保護，對於文件原始作者而言是一大負擔，因為必須學習各種不同的文件保護方式。因此本研究的首要目標，便是提供一文件保護機制，來保護各種不同類型的文件，讓文件原始作者僅需熟悉一種簡易的操作模式，即可做出對文件的限制，達到智慧財產權的保護。

另外，現有的文件播放器，並無提供講解錄製的功能，對於以文字為主的文件而言，會使讀者在閱讀時不易掌握內文重點。因此本研究另一個研究重點，就是提供文件的多媒體講解錄製功能，讓讀者在閱讀文件時，可在第一時間了解文件的重點所在。

With the convenience of the Internet, content creators can share their knowledge easily with document they have made through the Internet. Content readers can also read, copy, print, even edit any documents what he wants easily by way of the Internet. This is a great challenge on content creator's intellectual property rights. In order to protect the property rights for content creators, we must face the issue of document protection. Companies such as Microsoft and Adobe have taken actions on this issue. For example, Microsoft office provides a mechanism for document protection starting from version 2003, called Information Rights Management[4][5]. According to permission levels defined by content creators, individuals and group users are assigned to some access rights such as reading, changing, or full control. The Adobe company released the product - Adobe LiveCycle Policy Server 7.2 [8] - in December, 2006. For Adobe Acrobat's access control management, Adobe LiveCycle Policy Server provides to monitor the whole lifecycle from every document which is established or destroyed. Since Microsoft and Adobe use the mechanism for document protection only working on their own products. This will create burdens for content creators because they must learn different ways of setting for different document formats (i.e., doc or pdf). For this reason, the first objective of my thesis study is to provide a mechanism for document protection that can be applied to all kinds of document formats. The second objective of my thesis study is to provide document narration recording capability for the document under consideration. Through this extension feature, document readers can enhance the document’s capability to incorporate multimedia narration during the presentation mode.
