英文摘要：

A passive monitoring model of P2P specific information based on data verify algorithm is pres- ented. Taking P2P specific information as the object, A two-dimensional Bloom Filter algorithm is used to verify data as the judgment reference. To analyze two-dimensional Bloom Filter algorithm＇s time perform- ance, space performance and misjudgment rate, the algorithm compensates the current data verify algorithm＇s defect of taking more memory space and with low efficiency. Two-dimensional Bloom Filter al- gorithm can meet the performance requirement of passive monitoring model to data verify algorithm.
