無線射頻辨識 (Radio Frequency Identification, RFID) 是採用非接觸式的方式對無線射頻標籤達成自動化識別的技術，此技術運用在許多不同的領域上，其易於讀寫的特性尤其適合在供應鏈的物流管理上應用，讓供應鏈中的企業夥伴有效控管庫存和分享資訊。
供應商管理庫存 (Vender Managed Inventory, VMI) 是一種共同管理庫存的方式。其主要目的是整合供應鏈中的企業資源以抑制長鞭效應，並在共同的協議下由製造商管理庫存，分攤以往下遊廠商獨自負擔的庫存成本。
在這篇論文中，我們針對應用VMI的供應鏈設計了兩套多擁有者的RFID所有權轉換協定。目的是為了解決VMI在RFID實務執行上的困難，並增進庫存成本分配的效率。我們根據情境設計出能夠處理多個擁有者同時擁有某一物件的協定，且能根據情境取消某些擁有者的擁有權或是加入新的擁有者。我們也提出並解決可能的攻擊方式，以確保其安全性。
第一個協定應用了公正第三方 (Trusted Third Party, TTP)　的概念，讓企業夥伴在公正第三方的協助下共同管理庫存，並且將企業夥伴分級管理，達到具安全性的擁有權轉移目的；第二個協定則針對了應用電子產品碼資訊服務 (Electronic Product Code Information Service, EPCIS) 的供應鏈，讓企業夥伴能夠在雲端上即時的共享庫存訊息或處理擁有權轉移的方式。

Radio Frequency Identification (RFID) is a contactless automatic identification technology. This technology is used in variety of fields, its easy-to-read feature is particularly suitable for applications in the logistics supply chain management, and it permits business partners in supply chain to effectively control inventory and sharing information.
Vendor Managed Inventory (VMI) is an inventory co-management approach. The purpose of which is to integrate enterprise resource and inhibit the bullwhip effect. Moreover, the vendor will be able to manage the inventory under mutual agreement to share the inventory costs which were solely borne by the dealer in the past.
Two RFID multi-ownership transfer protocols aimed for the VMI environment are presented in this thesis. They are developed to solve the difficulties of the RFID system implementation in VMI environment, and to improve the efficiency of the inventory costs allocation. These protocols are designed to handle one object with multiple owners based on the situations encountered; the ownership of particular users can be added or terminated as needed. Possible security issues and strategies to prevent such attacks are also discussed.
The first protocol is referred to as Multi-ownership Transfer Protocol with Trust Third Party (TTP), as it would allow business partners to manage inventory in the control of TTP. It also provides a level mechanism to divide business into two levels, to maintain the confidential information privacy.
The second protocol is called EPCIS-oriented multi-ownership transfer protocol, which is designed to support supply chain members who uses Electronic Product Code Information Service (EPCIS). It provides an information transparency environment to allow the users to share information and control the ownership immediately.
