由於整個資訊網路的發展,將形成一個無所不在運算環境。而在此環境底下,將會出現許多憑藉著使用者的位置資訊來提供服務的服務。因此位置資訊在無所不在運算環境中可當作存取權限的一種驗證方式。但在此環境中,由於使用者具有移動性,使得驗證使用者的位置也變的越來越困難。而先前的文獻中,大多採用相對距離的觀念來達成位置驗證的工作。因此我們提出了使用RFID的一種新應用架構-Mobile RFID來建構整個環境並採用絕對距離的觀念來達成位置驗證的目的。而且我們的方式確保了使用者在等待驗證的期間仍在伺服器所能驗證的距離範圍內,同時在建構整個環境時只需耗費較少的資源,也較不受環境限制的影響更加的實用。

Ubiquitous computing environments result from the development of information network. Plenty of services which offer services by means of the locations of users appear in this environment. Therefore, location information can serve as an authentication means in ubiquitous computing environments. However, it is harder and harder to authenticate users' locations because users are movable in this environment. According to previous technical literature, many previous studies were done by using the concept of relative distance to achieve location authentication. We offer a new applied framework using RFID, Mobile RFID, to build the whole environment and make use of the concept of absolute distance to achieve the goal of location authentication. In addition, our method ensures that users are still in the distance for servers to authenticate when waiting for authentication. Moreover, building the whole environment consumes fewer resources, and is less influenced by environment limitations and hence more practical.
