Abstract
An interface is operable to receive an element for deletion from a bloom filter. The bloom filter includes multiple hash functions and an array. A processor is operable to generate hash function output values for the element using the hash functions. The hash function output values correspond to indices identifying bits in the array. A memory is operable to maintain supplemental data structure entries. The supplemental data structure has entries associated with the indices. The processor is operable to modify the supplemental data structure entries to delete the element from the bloom filter.
