UPnP讓設備之間具有無縫連接的能力，不需設定即能互通，帶給使用者極大的便利性。但這也帶來權限控管的問題，設備、服務與內容僅能提供單一種授權，家庭網路中任何身分的使用者都具有相同的授權，並且無法紀錄使用稽核。除此之外，UPnP是針對單一家庭網路環境定義之標準，若使用者希望在自己家中分享親戚或朋友家的內容，只遵循現階段 UPnP 定義的標準，無法達到此目的。
本論文設計一個數位家庭的管理系統，來解決上述的問題。管理系統具有符合UPnP標準的Control Point元件，能收集設備與服務的描述檔案，並能控制與訂閱服務。管理系統有預先瀏覽內容的能力，可預先瀏覽設備上的內容。並具備管理介面，能讓家中的管理者設定資源授權、瀏覽使用稽核、管理使用者與設定互信家庭等。
為讓管理系統能附加功能於UPnP設備，並可無縫整合到標準的UPnP架構中，本論文設計一實體資源虛擬化的方法。管理系統能保護與控管UPnP設備，提供使用者虛擬UPnP設備，管理系統能在虛擬UPnP設備上附加功能，讓設備、服務與內容具有授權、稽核與容錯的功能。並設計一個虛擬化設備為整合性多媒體伺服器，能整合家中所有多媒體伺服器的內容清單，提供使用者整合性瀏覽內容的功能。管理系統具有與異地信任家庭分享內容清單的能力，使用者要分享異地信任家庭的內容時，透過自己家中的整合性多媒體伺服器就能瀏覽信任家庭的內容清單。

UPnP allows devices to have a seamless connection without configuration. But UPnP have the issue of privilege management , everyone access devices , services and contents in the home with the same authorization. No auditing on devices , services and contents. In addition , UPnP define for single home network environment. . Based on current UPnP standard , the user can’t share contents on the devices of his friend’s home.
This paper developed a management system for the digital home, to solve the above issue. The management system complies the UPnP standard and has the control point , to collect description of devices and service , and can control services and subscribe eventing of services. The administrator can configure authorization of the resources , browse auditing of the resources , manage the users and configure the trusted home , etc.
This paper design a physical resource virtualization approach , to allow additional functionality can be seamlessly integrated into the UPnP architecture. The management system can protect UPnP devices , and create virtual UPnP devices for users , and add functionalities in virtual UPnP devices . The functionalities are authorization , auditing and fault-tolerance. Based on the physical resource virtualization approach , the management system has a custom virtual device , is an integrity media server .The integrity media server provides integrated content directory service , and integrated content list .The user can share contents from devices in his home and devices in other trusted home by the integrity media server
