近場通信技術(NFC)的出現在近年來在各個領域廣泛發展，在移動通信系統上，電子支付、交通運輸以及身分控制的應用已逐漸受到市場注目。因為其快速，可靠且非常容易操作的特性，NFC有望取代現有的許多技術，如藍牙無線連接和信用卡電子支付。首要解決的問題著重在案全與隱私部分以提高使用者的信心。本文提出的方法為NFC應用上最隱私考量的安全保護。利用實例來證明所提出的方法是可以被實現。在本文中利用了Andriod作業系統下具備NFC功能的智慧型手機，在驗證章節展現了此方式在現階段NFC的應用上，對於安全性的保護是可行且易於使用的

The emerging technology of Near Field Communication (NFC) has resulted in the development of many NFC mobile applications from the access control, electronic payment, transportation and many others. NFC is expected to replace many existing technologies such as Bluetooth in wireless
connection and credit cards in electronic payment, because it is fast, reliable and very easy to operate. The Security and Privacy issues need to be addressed and implemented to secure users’ confidence. This thesis proposes a method for NFC application with most privacy concerns. A private lock is used an example to implement and demonstrate the proposed method. An NFC Android cell phone is selected as the mobile device. The system configuration is designed and fabricated for the presentation. The results show the preliminary NFC application is feasible and useful.
