RFID technology has been widely used and the main problem is how to process the massive path data generated. The most important work in quick access technology of the RFID Database is supply the information of object movement patterns for people, as mining frequent path. There is little research in this area so far, on the basis of Apriori, the MP-Mine algorithm proposed in this paper mines the time-related path sequence.Meanwhile, we analyse the performance of the MP-Mine. The theoretical analysis and the results of experiment indicate that the algorithm is very effective. At last, we propose corresponding prediction method, which is very useful and valuable for enterprises.
