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.
