Abstract
Computer system security can be improved through the use of whitelists and blacklists based on Bloom filters in the context of real-time data and electronic actions. A transaction may use a specific asset. A first search of the specific asset can be conducted in a Bloom filter whitelist comprising first assets classified as having a first status. The first search may return a plurality of first binary results corresponding to different hash functions performed the first assets. A second search of the specific asset can be conducted in a Bloom filter blacklist comprising second assets classified as having a second status different from the first status. The second search can return a plurality of second binary results corresponding to different hash function performed on the second assets, and the specific asset can be determined to be good or bad based on values of the first and second binary results.
