A bloom filter is generated for efficient query processing for unsorted data in a column of a
columnar database. Bloom filters represented as bitmaps are generated for data blocks …

BACKGROUND As the technological capacity for organizations to create, track, and retain
information continues to grow, a variety of different technologies for managing and storing …

Implementing a Bloom filter index as a hierarchical data structure. Bloom filters are received
and their bit vectors are decomposed into successive bit sequences. For each bit sequence …

A Bloom filter index is implemented as a multiway tree that stores Bloom filters having a
predefined number of N-bit sequences. Nodes are labeled with portions of the N-bit …

Abstract Systems and methods for securing or encrypting data or other information arising
from a user's interaction with software and/or hardware, resulting in transformation of original …

A method for weighted data traffic routing can include receiving a data packet at data switch,
where the data switch includes a plurality of egress ports. The method can also include, for …
