摘要: A Bloom filter has been widely utilized to represent a set of items because it is simple space-efficient randomized data structure. In this paper, we propose new structure support the representation with multiple attributes based on filters. The composed Parallel Filters (PBF) and hash table accurate efficient query items. PBF counter-based matrix consists submatrixes. Each submatrix can store one attribute an item. as auxiliary captures verification value item, which reflect inherent dependency all for Because correct item becomes complicated, use two-step process ensure presence particular reduce false positive probability.
