Mine Cross-Level Location Sequences in RFID System
نویسندگان
چکیده
With RFID technology being applied in more and more applications nowadays, many researchers have focused on how to manage and analyze RFID data efficiently. Obviously, location information, which is an important part of RFID data, has the characteristic of multiple conceptual levels. Existing methods of RFID data management mainly deal with the cases of non-hierarchy (single hierarchy) or multiple hierarchies. In this paper, we propose an efficient algorithm to mine the cross-level location sequences. It can find the location sequences with items at different conceptual levels to help different analysts making decisions. Experimental results have shown that our new algorithm is practical and effective.

In this paper, we present a method named Signal Level Matrix (SLM) which can improve the accuracy and stability of active RFID indoor positioning system. Considering the accuracy and cost, we use uniform distribution mode to set up and separate the overlapped signal covering areas, in order to achieve preliminary location setting. Then, based on the proposed SLM concept and the characteristic o...

In this paper, a new approach for providing security as well as privacy is proposed. The un-authorized reading and relay attacks on RFID system is avoid by using location sensing mechanism. For example, location sensing mechanism used for location specific application such as on the door of ATM cash transfer van for providing security because the location of the van is fixed. So after reaching ...
