The deletable Bloom filter: a new member of the Bloom family

, , , and . IEEE Communications Letters, 14 (6): 557 - 559 (June 2010)

Abstract

We introduce the Deletable Bloom filter (DlBF) as a new spin on the popular data structure based on compactly encoding the information of where collisions happen when inserting elements. The DlBF design enables false-negative-free deletions at a fraction of the cost in memory consumption, which turns to be appealing for certain probabilistic filter applications
