METHOD AND APPARATUS FOR MULTISET MEMBERSHIP TESTING USING COMBINATORIAL BLOOM FILTERS

摘要

A method and apparatus providing improved set membership determination and group membership identification of candidate data elements using a single Bloom filter programmed to provide a plurality of non-zero f-bit binary vectors, where each of the f-bit binary vectors is associated with a respective group. The Bloom filter is programmed using one or more (but not all) of a plurality of hash filter sets.
